Saw this article this morning. Thought I'd share it.
http://www.phonearena.com/news/Samsung-Galaxy-S-III-wireless-charging-kit-introduced-by-Zens_id32935
Won't be coming out until September, for about 85 USD, but at least there will be options.
Does anyone know how much the official one will cost?

anyone know how wireless charging compares to outlet powered charging as far as strength and charge time?
$85 to me just seems ridiculous for a wireless charger when the technology obviously doesn't cost nearly that much. I think even after these official setups come out that I will stick with the palm touchstone conversion if I decide I want to do wireless charging. Even if I mess something up I can buy and screw up 8 of those before I even get close to paying $85.

I agree, the touchstone cost less, but with the touchstone charging rate is only 500mAh which has slow charging time.
I'll like to see the official one first.
The Qi standard offers a maximum of 1A in low power mode but a lot of the ICs on the market (TI) only support up to 500 mA. 500mA is about half of dedicated wall charging one I believe and the same as when you plug it into your PC to charge.

I plan on modding a case to do this. I am currently looking for some schematics because I have a feeling that this was provisioned in the design of the phone.

1A is more like it,the SGS3 has a charging rate of 1A through the mains.
i'm not in a rush for one so i'll see bother before I decide.

I'm not too sure myself, but I've heard some people say it takes longer and others that say it takes just as long. I know when my husband had the palm pre and would use his touchstone it really didn't seem to be a very noticeable difference in time.

Does seem a little pricey, but would love to pick up one for my desk at work, grab and go when I go out on the floor.
It's new technology(For phones at least) so obviously they gonna rip off the early adopters, I mean I bought one for Nintendo DSI for £3 which has identical technology to what they put in that so I'm gonna take that apart and if it works just buy a cheap battery cover and stick it together.
If it is qi or compatible then the energizer charging pad will work. It is well worth the money imo. I used it with tbolt every night , before my slim, lean, toned s3 arrived. Now I just can't decide whether to ripe one of my spare tbolt qi doors apart or wait for factory s3 qi door.
For what I've seen if the palm is so easy why not use the "proper" dock and hack a tbolt or similar door.

Hopefully this combined with the Verizon version that someone posted some photos of will put some pressure on samsung to hurry up and release the official one...
Sonof the zens unit is $85 then the official Samsung one will be $100or more.
still no word on the wireless kit?

For overnight charging, this is a good thing - extends the life of your battery. The higher your charge rate, the less your battery will ultimately live. The performance of your battery overall will degrade. Slow charging is a good thing.
If you want a fast charge, just plug into a USB cable if you are in a pinch.
Also, I read in the Galaxy Nexus threads (where the Palm Touchstone mod originated) that there's a software mod they are applying to increase that rate up to be nearly as quick as the 1A charger. The same type of mod may be applicable here.
I just got my ZENS+Shield kit for the S3 that has the protective shield instead of the OEM-style backing. I'm loving it!
Previously I had been using an OEM back with a Touchstone wireless charger installed in it, but I really wanted to have my elago slim hard case that makes the buttons recessed. I made an ugly hack that made it work most of the time but I hated having to fiddle with those Palm Touchstone chargers and making it align to the magnet.
Sometimes my cat could get annoying and just nudge it or maybe the phone would vibrate enough from alerts, it would get into this "charge-discharge" loop state that can't be good for the phone, sometimes even fully lose contact. It was just not very reliable -- I found myself sometimes just plugging it into USB to get a better charge.
The ZENS wireless back fits really well and provides the backing I wanted. I wish the texture was a bit more grippy but it's not exactly slippery. It's on-par with the stock grip. It's a bit heavier and slightly more bulky than the elago case but that's because it provides a bit more protection and has a rubbery pad for some sort of shock protection.
The charger is great too. I can put the phone in just about any position and it'll charge. They even brag it'll charge if you put it on a high volume speaker in the instructions (but it may take up to 2 mins for it to "negotiate" in that case.) It seems to charge faster than my Touchstone.
It's Qi standard so I should be able to use it with any charging pad. I was shopping for a second charger but the 3-position Energizer looks much too big as does the Duracell and the single position Energizer is slanted and I've read some people have issues with it sliding off. I like that the ZENS charger is flat and the size is nice, so I ordered another.
There's one downside to the ZENS charger but I think other chargers (except the Palm Touchstone) suffer the same problem: they do not use USB as a power source. My ZENS charger uses some ugly wall-wart. Also it's a bit more expensive.
Here is my review video! I am a huge fan of the palm touchstone wireless charging mod and this is the best way to get it...
http://youtu.be/NGvyWBOQy0U
Nice, couple questions.
Do you use a case? I have an Otterbox Commuter and was wondering if that is thin enough to still register.
Also, will that back cover work on the Energizer Qi charging system?
Sent from my SPH-L710 using xda app-developers app
Thanks for the video!, few questions tho:
Does it work with a case (I imagine this will be a popular question)
Is the quality of the back cover noticeable different to the stock back cover? Or is it a completely stock totally 100% the same back cover with the wireless charging mod?
And what charging pad do you recommend?
Unfortunately I do not use cases as I just use a clear shield so I have no idea if it works with otterbox or any case.
This mod will not work with any pad. It will only work with the Palm Touchstone. I dont recco any pad as I only recco the touchstone. I like having one in my car, at the office and one on the nightstand.

Can you try just putting something a few mm's thick between the phone and the charge pad and seeing if it still charges?
i got this mod with a 3mm thin case from ebay. they work perfectly.
Sent from my GT-I9300 using xda app-developers app
It works with a few mm but not sure how that affects charging. Please dont just take my word for it. Dont want you spending 30 on a back cover you cant use. But if it doesnt work i will buy it from ypu for a major discount. Lol
I dont believe qi is the way to go. The new nexus has wireless charging like the touchstone. I wonder if its compatible?
probably not. afaik, each of these wireless charging is proprietary and most probably incompatible with each other. The touchstone will only work with touchstone products (atleast from what I understand, it's different frequencies and also component parts differences)
You are probably right but i hope you are wrong... either way i am so surprised more phones dont charge like this.

Frequencies have anything to do with it. I'm pretty sure inductive charging uses magnetic fields to charge your device hence the giant coil in the phone cover. BUT, each base is most likely specific to it's counter part coil as different size coils will charge at different rates from the magenet in the base vs the amount of voltage and amps they put through the magnet. So it would make sense if a say Powermat didn't work with a Touchstone coil.
On the other hand, the touchstone uses a standard phone charger so it has a maximum of 5V at 1amp. I do not know what power source the Duracell Powermat uses (looked a little but didn't search long) so if it were to use a higher voltage at the same amps or higher amps at the same voltage then it may charger your phone faster.
NOTE: It should also be noted that if you use a different charging source with the touchstone base you could end up generating a different level of voltage and in turn damage your phone. It's not recommended to do this. The downfall (that I have found) with the touchstone setup is that it WILL charge through thin TPU cases and my Rock Quicksand case BUT the magnet is not strong enough to hold the phone in place. Since the touchstone is angled and not flat the phone starts to slide down and charging stops.
You can always switch out the magnets so your phone sits better on the touchstone. Its easy to change and it can make a nice diference.
Just ordered one. Touchstone rules.
@setzer715
that's an interesting read. thanks for clarifying the differences. I skimmed on articles about different wireless charging tech and remembered a few mentions of frequencies.
If only there is a standard that can adapt or provide compatibility with other methods... but that would probably drive up costs and probably extend r&d time.

Hello.
I'm using the same charger with my i9300. But it charging the phone too long
Also I have removed a wireless charging module from a custom back cover and install it on my original i9300 back cover.
First I thought to buy the Google one, but it just to small, and I need 2, for nexus 5 & 7, then I thought, why not to kill 2 rabbits, with 1 bullet, and buy a dual charger, the ZENS looks good, and big, so tablet not look out of place, any other recommendations?

The zen is consider ok, any charger with 7 coils tends to be little weaker, if you can find a 3 coils charger that is the best bet.
Of all the dual qi chargers i've tested, the yijieneng Q300 first generation version is the best, using it right now for the past 2 years, charges everything I have whiles other chargers has had problems of some sort.
This charger is hard to find, and the newer version are just load of crap, with reducing cost meaning cheaper component and very unreliable.
I ended up buying the ZENS, just for the size, and it works great with nexus 5 & 7 of mine.

The descrption on the box states all the info, maxell is also a rebadged version of the zens, or a japanese version known as sanwa.
The zens contains a total of 14 coils, 2 for each charging area.
Also note, all 7 coil chargers will need a dedicated charger, they will not run on USB.
A good charger is worth considering is the powerqi which has 3 coils and is powered using USB, you can find more information is the main note 3 wireless charging thread.
My USB cable charger cord that came with my P-600 is starting to loosen up. You know, when you have to adjust out so it's in the slot just right in order for it to charge. I know that you can't use just any AC adapter combined with just any USB cord to get the power needed to charge a tablet fast and efficiently. Are there any recommendations out there for a new AC adapter and/or USB cord that has been proven to work well with this tablet? (Besides buying a replacement from Samsung.)
Thanks.

Right. I think most smartphone chargers won't even be able to charge a tablet at all because a tablet, any tablet, needs more power (volts) to charge it effectively. I've tried using my Galaxy S3 charger to charge my Note 10.1 just to see if it would work and it shows the charging icon with a line through it (doesn't charge at all).

Any charger will work, but the higher-wattage ones will charge faster. Samsung ones are available all over the place AMZN/FLEABAY/A4C/etc. for cheap (<$10).
My original charger and a supposed duplicate purchased later seem to be charging slower as time goes by. Just as with my last purchase have read a good bit. But I too need advice on the best safe but fast charger and cable. I'm seriously considering the above recommendation for the Anker 40w (8A) 5 port charger. At most I charge only two devices at one time and usually only one. But if this is solid and reliable, the extra ports are ok. Before ordering, several questions:
- I notice the write up states two ports have the IQ charging - is this the case and are they labeled?
- I'd be charging my LG G3 with this too - any issues doing this?
- Lastly, seems cable length/gauge can affect charging speed, right? Which cables are folks having best experience with? I'm considering: http://www.amazon.com/Anker-Premium...ref=lh_ni_t?ie=UTF8&psc=1&smid=A294P4X9EWVXLJ. I prefer long cables if possible...
Bottom line, want a solid charger and cables for my Note 10.1 2014 Edition (and LG G3 if possible) that I won't have to replace in 6-12 months. If there's a two-port of same top quality, let me know too!
Thanks in advance!!

Went ahead and ordered the Anker charger and instead, am trying the http://www.amazon.com/Hi-mobiler-Go...8252875&sr=8-2&keywords=28/24+micro+usb+cable. See it's 28/24AWG hopefully will do the trick...only worried about the gold plating (ones tried before from Amazon seemed to get "lose" their prongs and slip out of my tablet's charging slot). Not sure if it's the gold being softer or ?
In any case, do let me know if anyone thinks the charger would create any issues if used on my LG G3!

All 5 ports are IQ.Charges a Note 10.1 2014, S4, Note 3, Z blue tooth headset and a LG tablet all at the same time and all quickly and fully. Great charger.
I found an issue with the Anker and one of the half a dozen devices of all kind I charged with it.
The touchscreen of my Huawei Tablet acts weird when connected to the Anker. This is a not uncommon thing, but first time i encountered it. And found the reason.
The Anker emits some weak 80v AC current on the GND line. Tested with another brand name charger(One for All, the universal remote maker). That one carried 20 Volts. My previous fav charger also emits AC, like with the Anker, the Texture of the tablet's aluminium case felt rougher during charging, when softly brushing over it with a finger tip. Only there were no touch troubles. Which can be avoided by touching the metal frame with your thumb during tapping the screen.

Is there any concern with this potentially causing damage, or just an inconvenience if plugged in while using the device (if one's unit was emitting that current)?
In my case, I haven't noticed this with either my Note 10.1 or LG G3. My guess is if it hasn't happened after a month or two, I don't need to be overly
concerned - the unit is functioning properly?
Personally, overall been happy with the Anker and haven't noticed any issues...
Thanks!
I had no damage so far, and the Note is happy with the Anker. And it seems that many or most chargers seem affected, like at least three of mine. Probably Samsung's too. Connect a multimeter to Usb 5v ground(the metal shield of the plugs seems to be griunded, though I tested with the plug for my Huawei tablet. Connect the meter's ground probe to something appropiate, like central heating, water pipe or the third line of the mains, which should be "protective ground" or something.
The current only produces a slightly bitter taste on the tongue, near nothing, but it's amazing how the feel of a metal surface changes.
I was reading for a while through the various subforums here trying to catch some info on selecting the "best" qi charger for charging our devices here at home (N4, N5 + some others). Finally after reading this review I came to the conclusion that in terms of efficiency, power consumption and charging time more or less all qi chargers perform equal. There are some exceptions tho, like the Panasonic TM101 with it's moving coil or the Tylt VÜ. Both allow free positioning (more or less) of the devices.
I noticed that especially with a case on, proper alignment becomes very important. So you give up fiddling with tiny microUSB connectors but have to deal with aligning the phone to accquire efficient charging. So I wonder is there any affordable charger out there with multiple coils?

I have almost all the big names out there. I have the nexus 4 orb charger and the nexus 5 charger. The energizer and LG verizon branded one. I also have the Tylt Vu. Now I have the AirDock in the car.
To me multiple coils is a feature and not really required. The only one I have that has multiple coils is the Tylt Vu. Its good, but has a big footprint so that charger remains next to my alarm clock and LG G Watch charging set up. I have the LG verizon charger that my wife uses for the Nexus 4. and I use the Nexus 5 pad at work because that had the smallest footprint. I have used various cases with each of these chargers, including the airdock. From the Spigen Ultra Hybrid to the Nexus 4 replica bumper for the Nexus 5, they all work. Sure the Tylt can charge my phone horizontally, but that's it really. lol.
I guess to answer your question, the cheapest multi coil? Well even though this technically not a mulit coil, it does locate your coil for you on your qi compatible device. Pretty neat IMO.
Panasonic QE-TM101

Here's a cheapy tylt VU clone

And here's a late addtion...the Nillkin 3 coil charger
http://www.ebay.com/itm/like/141370021990?lpid=82
Thanks for your answer. The Panasonic charger is, according to most reviews, not supporting trickle charging. If the device is charged completely the coil returns to initial position and the battery dicharges. In some cases there is also the charging coil repeatedly moving to the device and back to parking position again. Plus for some odd reason it is only available from Japan as direct import.
Tylt VU is way too overpriced, although the concept behind it seems great. Even the clone is too expensive.
So far the Nillkin Energy Stone looks good. Just cannot sind any serious reviews of it. Also only shipping from HK only which could be a problem due to strict german customs here
