Wireless Inductive Charging Palm Touchstone Mod for Galaxy S2 i9100

This post has info about a wireless charging mod for the T-mobile variant of the i9100, so I decided to do it to our variant.
I purchased a Palm Touchstone kit (cover and dock). The back cover (palm pixie) has the inductive charging circuit, so I removed the coil stuck to it using a heat gun (be careful), and removed the four metal studs that align it to the magnets in the touchstone base dock charging station.
I have the i9100T, which is the same as the i9100 international variant. I removed the battery cover entirely and made use of the space between my hard snap on case and the battery.
I used copper foil tape (eBay) to make the copper traces. I placed route from the +5v USB connection to the battery compartment using thin strips next to the top of the resistor, leading out to toward a thicker folded copper strip that heads to the battery edge of the pcb. I soldered over the thin trace to increase the current handling capability. Another folded strip leads to the grounded chassis screw. These two connections pair with the full width strips on the case. These run to the underside of the coil circuit strip, where two small square plates are pressed onto the copper strips. I glued a very thin rubber strip to the top side to ensure the connection. The metal studs, coil and circuit are glued to the case. I'd recommend tape also for water/moisture protection.
See the photos of what I did below:

Kudos! Great job mate. Will try and report how it goes..
Time to get one Palm wireless charger..

Very interesting, been looking for something like this for a while. I wonder if this could affect reception or the functionality of compass, Wi-Fi, Bluetooth, cell reception or anything else and damage it over time.
Could this also work with the coils inside the original battery cover or, if this is impossible could it work inside the extended battery cover (but without the extended battery, instead using normal battery) thus there could be enough space?
I thought about my own method, but this could be to simple: glue the coils inside the battery cover, then somehow glue or connect thin stripes from the coil to the contacts of the battery, right between the connectors of the battery and the contact ports in the battery compartment where the battery is connected to. This way, the battery could be charged through micro USB or inductive.
Do you know what I mean? Possible or too simple?

No, I have experienced no effect on other signals. The reports from other users are the same. The only effect it will have is on the compass, due to the magnets in the charging dock.
If you use the original battery cover, it will buldge out and look like ****. It also won't sit neatly on the flat charging dock. Yes, you could use an extended battery cover also. My solution seems to be the neatest for me, as I use a protective case anyway.
Don't connect the coil directly to the battery. I'm not sure if the coil circuit even has any battery charging functionality. You are much better off supplying 5 volts to the phone's charging circuits. I can charge either via induction or micro usb, both are working fine.

you've mentioned effects on the compass. Do you mean it is only affected while on the dock or does it permanently damage the compass due to the magnets in the touchstone? If this is the case, I'd rather not think about doing it. Would it be possible to use something else instead of the touchstone, like an inductive charging mat, e.g. a powermat, Duracell myGrid or Energizer inductive charger? Thus, there won't be any magnets. Of course one would still need the palm back cover with the coil.

The presence of magnets will just throw off the built in compass, I doubt very much whether it would cause permanent damage. You would quite possibly find that the compass refused to calibrate, due to 'abnormally high magnetic field'.
The PowerMat also uses magnets built in to the induction coil units on both the receiver and base in order to ensure correct allignment.

since it messes with the compass, would gps turn by turn have issues too ? since I have no idea if the compass is used to determin the direction for the gps.

So, I'm getting ready to look for and purchase the necessary parts to do the mod. This is just to confirm that I'm getting the correct parts.
I need some copper foil.
This back cover here: http://www.amazon.de/Pixi-Touchston...KPGU/ref=sr_1_1?ie=UTF8&qid=1353844406&sr=8-1 (Palm Pixie Touchstone Back Cover). Palm Pre back cover won't work?
And this: http://www.amazon.de/Pre-Zubehörtei...0JGY/ref=sr_1_3?ie=UTF8&qid=1354893172&sr=8-3 (HP Pre 3 Touchstone charging kit with international charger)
and this: http://www.amazon.de/Samsung-EB-K1A...HRY8/ref=sr_1_2?ie=UTF8&qid=1354716530&sr=8-2 (Galaxy S2 extended battery and back cover). I'm modifying here and use this instead of the snap on case. I hope I can fit the extended battery and the induction mod all under the extended battery cover. If there is not enough space, I'll have to use the normal battery and extended cover.
Is this all correct?

Hi mate. I'm interested in doin the same with my SGS2 inside the 2000mA cover with the 1650mA battery. I've already invested in a Touchstone cover and dock and like you I was looking to apply the coil directly to the battery. I did some research and a little poking around the four terminals on the galaxy battery with my multi meter. I'm led to believe the battery has its own circuitry for protection which is controlled by the extra terminals. How far did you get with your project, did you experiment applying the coil directly to the battery?

no, I didn't apply the coil to the battery for the simple reason that it makes switching the battery easier if it's empty or faulty.
However, I did not follow the exact steps in the description. As you suggested, I wanted a more elegant solution and so I stuck the coil, magnets and circuits from the palm backcover to the 2000 mAh extended battery cover and used it with the 1650 original battery.
I also did not use cooper foil but soldered small wires to the + and - pole of the Galaxy's board, these I connected to the approbiate places on the circuit inside the Galaxy extended back cover. This way I can remove the back cover and lay it next to the phone when switching the memory card, sim card or battery.
From the outside, no mod is visible at all. It just looks like the extended battery cover. Very elegant. However, due to the size of the circuits and coil, you can't put the 2000mAh battery and the extended battery together. It's just to thick. Trust me, I tried.
You can only use the coil and circuits with the standard battery and the extended cover.
If you feel good at doing this stuff, then go ahead. You won't regret it. I myself helped my dad while he was doing it because he has a soldering iron and a lot of experience with this. I didn't want to risk anything.
It's well worth it. I have the mod since Tuesday and my phone has never seen a charging cable attached to it since then (although you can still use it if you want!). It really awesome and cool. No searching for the charger cable, no plugging in and out, no tripping over the cable and knocking down the phone, no wear and tear. Just drop it on the touchstone and it charges!
The phone gets a little hotter than usual while charging but nothing serious. When charging is finished, the temperature is normal again. Lastly, it charges a little slower than with the charger cable. The phone recognizes the touchstone as USB connection so charging is 450mAh not 650mAh.
I just purchased my second touchstone from ebay so I can charge at two places without carrying around the one touchstone. This is how much I like the mod.
If I buy a new phone sometime in the future, it MUST have inductive charging built in! It's a whole new feeling. Plugging in the charger cable is so 2010
Thanks very much to the OP for the mod. It's really cool and works flawlessly!! The only thing I regret is, that I didn't do it earlier.

There is no problems with the reception of the phone ?

no, there are no problems at all! See, the back cover with the coil and the touchstone were originally released for the palm/hp smartphones pre, pixie and a bigger touchstone for the hp touchpad. All these phones have gps and everything. HP wouldn't release this if it affects their phones function's negatively. The mod just uses these parts and ports them to the S2.

Hi!
I managed to do this mod with extended cover + 2000 mah battery :laugh:

very smart to use the mold on top of the SIM card holder and put the circuits there. Should have thought about that earlier! I glued them to the inside of the extended battery cover and used little wires so that I can remove the back cover, memory card, SIM card and battery if necessary without affecting the mod.
I have now the extended back cover + induction mod + standard battery. Looks nice and original. The icing on the cake would have been the extended battery included as well.
Anyways, keep it going. I hope to see the final result. Trust me, inductive charging is so cool and convinient.

Thanks vry much:good:

thanks

What happenes when I put the phone on touchstone and plug a USB cable in? Does USB charging "override" inductive charging?

Good question but as my mod use usb socket I am not able to check
Sent from my I9100 @syiah5 using xda premium app

I don't advise doing both as the S2 doesn't recognise wireless charging like the S3. Your effectively doubling the input current which as I experienced lit the screen brightness up vastly for a split second until I broke the connection. I was lucky not to cook mine as is it still works.

Awesome Idea!! Will probably try it by myself but ill use the extended Battery i think the cover has still some space to loose
Question, how thin is the solution? more than 2 millimeters?
What happens if we "increase" the usb charging speed via custom kernel to 650 ma ?
Does it work?

Mod for sony liveview stock watchband to facilitate charging

Hi,
I have here a simple mod for the stock sony liveview watch band to facilitate charging without taking out the liveview at its retaining base. I would just like to share this simple mod so that anyone with a broken tabs that clips the liveview in place can use their stock watchband again (Mine broke the other day ,the engineer who design this thing must be fired) or for those anybody that would like to use their stock watchband and was tired of constantly taking out their liveview for charging. This mod will allow the liveview to be charged still attached to the stock watchband. (Caution; Pics are very huge....sorry). Liveview app has a recently updated so it improves connectivity but no auto connect yet. Otherwise I'm enjoying it more now on jellybean than previously where it stays more of its time inside my desk unused, so for now will be using it more frequently.
Materials needed are the following:
a. Long nose flier (preferred as it allow small length bending of the paper clip)
b. paper clip
c. super glue (for those with broken tabs)

Steps:
1. Cut, measure and shape the paper clip according to the image shown. Remember to measure the lenght of the clips and its bending in proportion where the retaining pin is attached to the watch base. ( I would not explain further as a picture is worth a thousand words)
http://i1223.photobucket.com/albums/dd501/gorgycuads/IMG_20121008_105715.jpg?t=1349708412
2. when done, remove the stock retaining pin from the watchband. You will have to enlarge the hole where the retaining pin is attached to the base of your live view by using the extra paper clip and heating the tip of it using a gas stove, a candle or anything at your own convenience. (Be careful with this procedure, take extra caution). While the tip of the paper clip is still red hot immediately insert it to the hole and take it out afterwards and do the opposite side.
3. Now that the hole is larger, and your modded paper clip pin is ready to be inserted to the notch. Now replace the stock retaining pin with your modded paper clip retaining pin and place it back. Put your liveview back. For those with broken tabs super glue on the back of your liveview and put it back allow the glue to dry for several minutes.
Here are some pics in action: You still retain factory look and gain some convenience charging with the port without removing anything( except for the rubber cover which you will still have to open). Enjoy (Sorry if I have made some grammatical error or did not explain properly as english is not my primary language).

nice idea... i'll try how to think how to do it on my watch strap

Good Job. I have to look for a technician to do it for me .

superb job! i am doing this right away! wish me luck
---------- Post added at 03:17 AM ---------- Previous post was at 02:43 AM ----------
wooaahhh done! great idea... and quite easily achievable

Thank You!
Thank you so much for this tip,
without it i would have to struggle to remove the watch from its strap everyday as on my one it is way to stiff,i found i didn't have to make enlarge the hole for the paperclip and is quite sturdy :good:

just did this and I didn't had to enlarge the hole

Could use some advice.
This thing has a TINY battery and doesn't use that much power.
As a watch mode it's in the light all the time. What if we never had to plug it in to charge it again... but instead kept it plugged in the whole time to a solar watch strap?
ebay has these (which, two, in series relation might work)
http://www.ebay.com/itm/PowerFilm-F...00918136469?pt=UK_Gadgets&hash=item2ec7a77695
http://www.ebay.com/itm/Thin-Film-F...489?pt=LH_DefaultDomain_0&hash=item3a81313771
and my favorite (one of these might work... don't think their calculation can be right: e.g. 2V *420mA = .84W
So if we .84W / 5V = .168 = 168ma that's more than standard usb @ 100ma and should give enough juice over 8 hours of office and sunlight right? Plus this thing is waterproof and looks sick (they even have a black one now too).
for dirt cheap that puts out decent charge ... anyone have any ideas how to fashion one of these (or two) into a watchstrap?
Perhaps solder on a male micro usb that will couple to liveview on that side and then a regular watch pin on the other side.
Wouldn't this generate enough energy to never have to plug in and allow unlimited use?
50ma * 8hours a day??? for a 100mah ish battery?
Am I missing something here?
The only issue I see is the voltage... usb needs 5V +/- .25ish?
Would one use a voltage regulator?
Any input greatly appreciated. I'm more software than EE.
Thanks,
Frank

FYI: Liveview mn800 Sony $18 free shipping! Just wanted to pass it along.

IT WORKS! IT'S ACTUALLY CHARGING!
Just need to clean it up a bit and do some testing. But it is indeed charging.

How did you do that???

Nice!
Just ordered a liveview the otherday for $20 from amazon. Can't wait for it to get here! How did you get the solar strip to charge it, that's a great idea?

Just need to get a solar band to be about 5v. Ebay has cheap voltage converters with usb outputs. I'm soldering on a male micro usb and removing female full size usb port. I cut the end of the charger that came with the live view off... only two cables inside. Having some weird results though. Will report more after some more tinkering.

Goddamnit. I cant figure it out. It doesn't seem to be working. The charging indicator light comes on and the screen charging icon indicator shows charging. But even when the device is off and left on the charger... no charge seems to accumulate in the battery.
Not sure if the voltage regulator efficiency is to blame resulting in sub 100ma output??? (This seems to be the case as my phone doesn't report charging). But why would liveview report charging but never charge?
The other possibility is that I need to incorporate a diode, like an led, inline to keep current flowing back from liveview to boost converter when a cloud goes over? Oddly, if I disconnect solar cell... liveview seems to illuminate an led built into regulator. Odd!
This morning I charged for about twenty minutes and when I disconnected, the charging light stayed illuminated for several minutes and liveview would not respond.
Anyone have any ideas?
I'm hoping I don't have to incorporate a tiny rechargeable coin battery intermediate to liveview and the solar cell.

I don't know much about electrical setups but it sounds like the current is flowing into the liveview, then back to the converter and is circulating in and out. Basically, the solar strip is charging the liveview, and at the same time the liveview is powering the converter. This would explain the led staying on after it had been disconnected as the remaining charge in the battery was sent to the voltage converter. Did you try disconnecting everything (usb cable and all) after charging it?

Not yet. Been busy at work. But dying to try. I agree with your assessment. Wish I had an extra led to isolate so there was no backwards flow.

I'm hitting 59.6milliamps on an overcast day with a portion of the panel covered.
Usb provides 100ma max non-negotiated. I'm seeing the liveview pulling 74ma from a usb computer outlet. Getting close!
There seems to be some accumulation. I'm thinking of incorporating a tiny rechargeable nimh coincell to balance everything out and provide more current. I don't see any negative current flowing from live view beyond the voltage converter to the ammeter. Successfully charged my bt headset. Getting there.
I've got, what I hope, is a more efficient converter on the way.

Never run out of battery again on liveview:
Charge from your phone!!!
Otg male micro to micro usb will charge the live view from note2 usb.
3300mah note2 battery at about 100ma to live view's 100ish... while liveview provides an awesome second screen! And remote control/ game D pad plus select. Sick!!! Fxuck yeah
Phone remote.
My note 2 is so big... I need a remote.
In the hood don't even need to whip out note2. There's some serious benefits here.
Schematic attached for my idea of male to male plug to charge liveview from phone:
*Data (D+/D-) generally green and white wires not needed.
*Depending on the orientation of your phone port and whether you want second screen face up (as I do) then there's this difficult twist.
Use the shield to send GND and maybe a conductive ink pen to draw a trace from 1 to 5.
*4 and 5 on OTG side must be coupled for phone to detect OTG.
*Not sure how the phone will react to seeing pins 2/3 D+/D- as open. Hope this works. I think it will.
My phone charges the liveview using a 2 conductor cable... so they should show open anyway.
*if your phone connector is reversed or you don't care about the orientation (which might be nice in some configs)... this is a **** ton easier. Only need to couple two male micro-b to male micro-b with all connectors going straight through. (and couple 4 and 5).
Schematic up just FYI FWIW.
ONE CAVEAT to this. Without the data cables you can't negotiate for higher current above 100mA. But for bluetooth peripherals and liveview... this should be quite sufficient.

Solar charger wrist band working on smartwatch1! They are going to have to build their own for smart watch 2 as I believe it's proprietary connection.
Best news ever just hit... Sony OPENS up dev on smartwatches; home brew friendly behavior? Hell yeah sony! This is such a relief, if this is the new Sony, I'm getting ps4 *****es! The boycott is over! I'm totally getting smarter watch 2 when it comes down to a reasonable price...Cannot wait for full multitouch.
Does anyone have specs fir smart watch 2 plug? Its not microusb is it?

OR - the really easy way if you don't need structural coupling:
$5
http://hakshop.myshopify.com/products/micro-to-micro-otg
Male to male
micro-b to micro-b
with OTG (on the go) enabled.
Already all the work is done... great cable to charge liveview directly from phone!
Also works with your bluetooth headset, mouse, keyboard, and the like.
One improvement on this would be to couple in a resistor across the data lines to allow charging the phone while derivatively charging the liveview.
I'll leave that to the other threads.

Review of RAVPower wall charger for Note 2 batteries (incl ZeroLemon) w/pics!!!

This is a review of RAVPower wall charger for Note 2 batteries. http://www.amazon.com/RAVPower®-RP-UC03-Charger-Samsung-GT-N7100/dp/B00DGNMD4E/
I'm pretty sure by now we all got a number of OEM size, double extended size, and triple ZeroLemon size batteries for our Note 2. Most of us using our phone to charge these up, but it's probably the most inefficient way, and you need an external charger. For a slim OEM size battery its not a problem, those are available everywhere. Some will fit double extended batteries as long as charger doesn't have a cover, but how many times a question been raised in our forum about charging zerolemon battery which has triple size and capacity? I personally lost a count of it.
So what is the choice? Sure, you can look up Note 2 battery wall charger on ebay and will get a bunch of hits. The problem, there are two types of charges with a different battery layout. For a slim OEM battery it doesn't matter since you can flip it on either side. But with double or triple capacity - you can't. So first you have to be sure battery fits across the charger instead of sticking out half way. The next problem, and that is a big one - they confuse a hell out of you by writing a spec of 5V 1A charge. These wall chargers have usb output which can provide 1A of current, but the actual DC battery charger is only 350 mA which I tested in reality to be even less than 300 mA.
The solution? You need to get a specific wall charger that fits battery across and has a spec of 600 mA for DC port. That is the fastest available wall charger I have found so far. I have seen a number of vendors offering them bundled with their batteries, but nobody sells them by itself. If you already got batteries or your main concern is how to charge up externally your enormous ZeroLemon slab, RAVPower sells this charger by itself for $9.99 and it WORKS perfectly with either slim or Zerolemon battery. True, 600 mA of charging current will take you 3 times longer in comparison to your 2A charging from within a phone. BUT, it also twice as fast as buying any other cheap ebay 300 mA wall charger. Plus, convenience of charging it externally why you are using a phone with another battery has a big advantage. So until someone else release a wall charger with a higher charging current and capability to accommodate larger Note 2 battery sizes - this RAVPower wall charger is the way to go!
Here are the pictures.

Exactly, Anker sells it as well as a few other vendors. But they all sell it bundled with their 3100 mAh batteries. So if you are buying those bundles, you will get exactly the same battery charger. I was looking just for a charger without batteries. That was the only place selling 600 mA version of it separately.

9300 mAh / 600 mA = 15.5 h With some variation, give or take, I would keep it on for about 16-17h for a full charge from empty. Also contacts in those chargers could be a bit finicky and sometime a slight move can make charging light toggle. Yes, this is not your fast 2A charging inside of the phone, but the beauty of this is to put it on the charger and let it sit there for a day while you continue using your phone with OEM or double capacity battery.

Unfortunately for the likes of us in Australia, we don't have such options easily available to us (Amazon, etc).
From this http://www.youtube.com/watch?v=vgTdAUcT87U, it states that it can charge the battery at 1.7a (if the supplied note 2 charger is connected).
Only problem is the charging pins are on the opposite side, so you won't be able to plop the ZL or other larger capacity batteries in and charge, unless you modify the pins to accommodate it (and dismantle that flip lid)

That is precisely what I did to that same model in the youtube video.. I removed the lid and transferred the charging pins to the other side. Coupled with my custom 3A charger and high amperage cable my ZeroLemon charges from dead to full in 5.5 - 6 hours. This setup has been working flawlessly for me for months now.....

Ive just bought the zerolemon charger, which is basically a copy of this ravpower one. I have two samsung desktop chargers too. Im not overly impressed with the zl/ravpower charging times so I am considering modifying one of them samsung ones.

I would appreciate if you could share ypur method. Ive taken in of my official chargers apart and without soldering I dont see how it can be modified. Id like to convert one for use with my zerolemon battery.

☆★

Hey gang, sorry for the delays. I have been asked about many of my mods, from the s-pens to the rugged case, etc., but haven't had much spare time to take photos and upload, etc. I have been crazy busy, but, will try to set aside time in the future to make posts on them.....
For this mod, basic soldering skills will be needed. First I desoldered the contacts from the circuit board. Then, I had to figure out the proper new location. I cut out a rectangular hole in the new location. Also, in the battery compartment, there are two little tabs on the sidewalls that won't let the battery sit right unless you modify them.The contacts were rewired and then epoxied into position. I wanted to make the charger as small as possible, so, I chopped off the whole front section that usually cradles the phone since I would never use it again because of the thickness of my phone with the zerolemon. I removed the lid and covered the holes where the hinges used to be with black plastic. Then, I repurposed part of the lid to make a cover for the cradle section that I had cut off. Next, I needed a way to know of the charging status. Unmodified, the zerolemon battery covers the status LED, rendering it useless. At first I was going to relocate the LED. Then, I figured out the exact location of the LED and then drilled a sight hole on the side of the housing. It works perfect and easily visible when charging the zerolemon. When I am able to make a full post later, I will show you pics of it visible while charging the zerolemon. To polish off the mod, I made labels. In the meantime, here is a pic.....

Doesn't matter what the input, just care about the output. Also, keep in mind that you have 2 output ratings, one for usb port (1A vs 0.6A) and the actual battery charging output 0.6A which is common in both.

thanks for the clarification!!!!

So the rated input is 750mA, and output is 5W? That means it doesn't charge at 1A like some of the other chargers? (i.e., Nexus Orb, LG's circular charger, etc?)

No qi charger charges at 1 amp. There's a 30% loss in the wireless transfer. Mine charges at 640mAh

My sound noobish, but that means charge time is really slow.

I wouldn't say really slow. Think the stock charger is 1-1.3 amps so its probably about half as fast as the plug.

I really love the design, but I hate the price.

Its really the best wireless charger for the price, no need to hit the sweet spot since its position agnostic
Sent from my Nexus 7 using Tapatalk 4

i got one from kickstarter too.
I like it a lot, my only gripe is the angle of the stand, its not the greatest angle to view from bed side. I use my tablet as my alarm too, and its a weird angle to see the clock from alarm app while in bed.
Other than that, I would say it works great. Doesn't charge as fast as a wired connection, but it will charge the tablet to 100% overnight. It has charged for me 100% every time. I also have the clock app running and the screen dimly lit to show the clock the whole night.
Hope that helps show it can charge well enough.
Also side note, i have not found a angled Qi charger on the market. all the ones i found are flat on the ground.

$70+ is pretty expensive for a wireless charger now a days.
I'd say if you want an angled wireless charger, pick up the nokia dt-900 for $25 and a cheap tablet stand and attach them (there's a thread about here). Not quite as pretty, but less than half the price and you can adjust it.

$99 - NO WAY

wierd they were $50. verizon is selling them cheaper http://www.verizonwireless.com/b2c/...ccessory&&change=&zipcode=&state=&fd=&filter=

Before : 3 colors, 70$
Now : only Black 99$
I was already wondering if I should buy one, since I have to pay additional international shipping (25-30$) + taxes (20% :/)
That's a definitive NO given their price / marketing policy
I'd rather pledge this, even if it is not wireless charging ...

Yeah, no kidding. I was gonna buy one, but there is no way I am paying $100 for it. $70 was expensive enough (which is what it was last time I looked at Tylt's website). That's a pretty ridiculous price jump. Guess I'll be looking elsewhere.
---------- Post added at 01:55 PM ---------- Previous post was at 12:58 PM ----------
So, I sent an email to Tylt and asked why the giant price jump. They got right back to me. Here is what they said:
Hi Phil,
Thank you for contacting TYLT customer support. It's very expensive for us
to produce this product so we had to increase the cost if we want to stay in
business. Thank you for the link and I will definitely forward this to our
management team.
Thanks,

It doesn't make the price any easier to swallow, but I do really appreciate them getting right back to be with an answer. I suggested they check out what people are saying on forums, because it isn't good.

Tylt Vu Review (ReVu?)
I received my black TYLT Vu the other day and have been testing it (and admiring it). I am concerned with the number of insertions my phone and tablet will endure for their micro usb connectors so wireless charging is a great solution for me. This made me very interested in this Kickstarter project and the Vu itself.
Ive attached pictures in the Android Central review I posted a couple weeks ago but the ones posted by the original poster cover that off well enough so no need to duplicate.
http://forums.androidcentral.com/google-nexus-7-2013-accessories/309752-qi-pad-will-charge-nexus-standing-up.html
The packaging is a rich/amazing clear firm plastic box and a bright green plastic rim around the front edge. Included inside is the stand, a power brick in the horizontal orientation charging position with a round power connector (not micro or mini usb) and a permanently attached long cord from wall plug/brick to the connector. Also included is the requisite standard regulatory/safety pamphlets. The long (approximately 6' long) cord on the charger is a good feature allowing for plugging in and placing the stand almost anywhere. The stand itself is solid and stable with a sort of soft touch plastic The connector is a little challenging to plug in but once inserted feels solidly in place and shouldn't disconnect if you were to knock the stand off a desk or night stand. The stand has a nice cable management slot so the connector is protected and provides good bend relief from the connector leading out of the stand. The connector is not a micro usb as I had hoped but a round 1-2mm connector. Apparently this is due to the power draw of the coils in the stand being higher than the microusb standard.
I tested it on my Nexus 4 and my Nexus 7. Detailed results are for the Nexus 7 but similar results were observed on both.
Nexus 4
It works in both orientations for the Nexus 4 quickly recognizing the phone and promptly beginning charging in both landscape and portrait modes. The green light comes on to show that it is charging. For the Nexus 4 the phone also charges with a thin Nilikin Case on the phone with no issue. The phone does not charge with a Ballistic SG Case installed.
Nexus 7 (no case/cover installed)
The Vu only works in landscape mode for the Nexus 7 as in portrait mode the center of the back of the tablet reaches above the charging edge/coils of the Vu. The Nexus 7 also begins promptly charging with the Green LED lighting when placing the tablet on the charger with the Home capacitive button centered over the LED. With the Dashclock Battery Widget running it shows it "xx% - Charging (Wireless)" until 100% and shows "100% - Charged" when charged.
Concern
When the Nexus 7 reaches 100% it appears that it does not shut down charging waiting till it discharges significantly before starting again. It cycles on and off going from "100% - Charged" the LED cycling to Red briefly to "100% - Not Charging" back to "100% - Charged". After letting it sit on the charger and discharge for some time it cycled back to "99% - Charging (Wireless)" to repeat. This takes some time as the battery discharges very slowly.
My preference and expectation would be to have it to charge to 100%, go to sleep, gradually discharge to 90-95%, occasionally checking and then restarting the charge. Cycling at 99-100% could impact battery life. Also, once it reaches 100% and starts the cycling the temperature seems to stay at about 29 C (room ambient approximately 23 C) so this doesn't seem to be a an issue that would impact battery life, however, I'm not 100% sure about that. When it cycles back and forth the tablet makes no sound so this also shouldn't be an issue using it as an alarm clock next to the bed. The LED cycles to Red briefly but the LED is not so bright that this would be an issue for me.
This behavior is not as I expected and TYLT stated it would operate and in fact matches a early design issue they reported to Kickstarter Sponsors. TYLT stated they were aware of the issue and were working to resolve it prior to shipping to sponsors. I have reported this to Customer Service and their engineers are looking into it and they have stated they will have a solution in the coming weeks. Customer Service is extremely prompt in responding and provided me with the confidence that this is being looked into.
Pro's
Clean solid feel design
Good length cord on charger
Small total real estate on desk
Charger brick is horizontal which allows for access to other plugs in the wall plug
Con's
Price (Price has been increased above the originally high price)
Charging cycling
Minor - Power connector being round (if it were micro usb I'd have another power supply to use)
Overall
This product is great. It looks good, is stable on my desk, charges my Nexus 4 and Nexus 7 well, and has practical considerations such as long power cords unlike many other included cables.
As I mentioned previously, I am concerned with the number of insertions my phone and tablet will endure for their micro usb connectors so wireless charging is a great solution for me. Also, being able to see the display while charging is a great option allowing for use of the phone or tablet as a alarm clock, daydream clock or music player. The stand with the phone/tablet sitting on it does not take more real estate than a pad charger would. Overall, It is attractive and functional.
I'm not sure if it is operating exactly as expected but charges quickly. Unfortunately, if the cycling of charging might impact battery life I won't know that for some time. Once I learn more from Customer Service I'll report back.
Summary
I wouldn't hesitate to have this on my desk at work or on my nightstand next to the bed.
I would purchase this product again but might wait on the resolution to the charging cycling if I were concerned about it.
I will likely get a second unit for my desk as my first will be on my nightstand.
This is my first ever mini review so be gentle on comments. These are my opinions only.
No tablets were harmed in the making of this review.
If you have questions or need clarification PM me or reply to this post.

looks like they dropped it back to 69.95 and there is a 10 percent coupon out there.

But to late... that price gouge pissed me off.

Seriously, I wanted to get this stand for the longest time but the high price followed by the price jump then backtracking leaves me with little to no faith in this company and their products.

Ravpower Qi Wireless Charger and a wireless wireless charger?

http://www.amazon.com/Upgraded-RAVPower-Qi-Enabled-Wireless-Single-Position/dp/B00DMZPQIG/ref=sr_1_1?ie=UTF8&qid=1384638435&sr=8-1&keywords=ravpower+qi
So after getting my Nexus 7 I wanted to get a qi charger but I didn't want to get a charger for a tablet; but after getting my Nexus 5 I didn't need much more of a push to get one....or two.
Introducing Ravpower's QI wireless charger and Ravpower's Qi wireless powerbank charger.
First we'll do an overview of the wireless wireless charger aka Qi charging pad w/ built-in 4800 mah battery powerbank.
As usual, Ravpower packaging has the Black and Green Box.
Included is a wall plug with usb port, a micro usb cable and the Qi powerbank.

}
The size is roughly as big as the Nexus 5 which is a nice thing for me.
The one knock I can think of about the Qi powerbank are the indicator lights. They bleed into each other. It doesn't affect the functionality but would be nice to have that sorted out.
There are 6 lights in total.
The first one on the left is merely indicating that the powerbank has power and the power button has been pressed to start charging. Its a pink light.
Lights 2-5 are blue and indicate how much power is left. 4 lights = 100%, 3 lights = 75%, 2 lights = 50%, 1 light = 25%
The final and sixth light is the wireless charging indicator thats green. If its flashing green it means that is charging your device and is in the correct position.
It was able to charge the Nexus 5 and Nexus 7 without a problem. The nexus 5 had a Ringke Slim case and the Nexus 7 had a Poetic Folio case.
Charging the Nexus 5 here is some charging times
Starting @ 4:53 and 27%
5:26 @ 45% ( 33mins for a 18% charge)
5:44 @ 56% (18 mins for a 11 % charge)
Now, finding the "correct" placement is simple and fast. I've read other reviews where it took awhile to find the sweet spot to get the charging to start working. With both powerbank and non-powerbank versions it was fast and painless.
Simply placed it on top of the charger and it made a beeping sound and starting charging. Now don't expect it to be halfway off the charging pad and start charging. It just has to be semi close to fitting the phone on the pad and it will do its job. There isn't 1 spot it has to be in.... its like a range of spots with some wiggle room if it shifts on the pad.
One thing to notice is that it is a wireless powerbank, so leaving it plugged in isn't a great idea for it will be constantly draining the powerbank and recharging it while plugged in and wirelessly charging your device. If your goal is to have a set wireless charging pad than you are better off going with the wireless charger without a powerbank but if you are constantly on the go, study at the library or starbucks where there are a shortage of wall sockets then this might be your answer. I like going to starbucks, not having to find a table near the wall socket....set the wireless charger on the table and charging my nexus 5 on it while I study or do cases.
The build quality is top notch and seems like it will hold up to on the go bumps and bruises. Also, if you have a second device like a tablet or camera that don't have a built in wireless charging capability; than you can use the standard usb port on the powerbank to charge your device; just needed the usb cable to do so.
NOTE: There is an updated version with a non slip rubber center ring on the pad to revent slipping and sliding of the device. Contacting Ravpower that is the only difference between the one I have and the updated version.
Updated version with rubber non slip ring:
Non-updated version:
Now; if you dont need a powerbank and would like a stand alone charging pad than the Ravpower Qi pad w/out the powerbank is your answer.
This is the updated surface with the non slip rubber ring and it can stay plugged in without having to worry about the built in battery.
It comes with the same accessories as the powerbank version, usb cable and a wall plug.
It was able to charge the nexus 5 and nexus 7 at the same rate as the powerbank version.
It is slightly thinner and slightly larger.
The Non power bank version has just one single light that blinks when its wirelessly charging your device instead of 6 like the powerbank version.

Thanks for the review and pics. I wanted to just confirm, the power bank version will provide wireless charging capabilities without the actual device being plugged into the wall outlet? Even though its obvious, I just wanted to confirm that it does give that feature. That would "TRULY" make it wireless.
I needed a power bank for travel, since my family is traveling soon. On top of that, if this one gives wireless charging on-the-go, that's a sell for me. Also, how much time did it take for it to charge your N7?

For how much?

Yes, it charges wirelessly while not plugged into the wall. The Nexus 7 charge times I'll post tonight as I have them at home. That was the main selling point for the powerbank qi charger for me, plop it down on a starbucks table and voila..... no searching for an outlet.

if the xperia has built in wireless qi charging; then it should be able to be charged wirelessly. But IT MUST have that feature.
The older version without the rubber non slip ring is sold out on ebay and amazon. The updated version should be stocked back up soon; I'll email ravpower and give an answer when that will happen. The price I don't know as the updated version might be more or might be less.
