Zens Wireless Charging Kit

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.

Wireless charging. Finally

So wireless charging is here for the s3 by Duracell. Finally. Yeah mad expensive. I'll keep using the wired one
Thanks to Facebook advertizong for the link. Lol

I've had wireless charging since August . . .
Have one in my car and one next to my bed. The phone locks to the wireless dock with magnets which keep it in place and at an incline rather than flat. It's nice. Cost me ~ $25 for all of it.
Oh...and mine doesn't require an ugly case like the Duracell or some sort of special back cover. Phone looks like any other S3.

Ok. I'll try compiling something later tonight. It is basically based off of the Palm Pre charging that everyone on the I9300 forums has gone over except I change the magnets so it's secure and also shave the back cover so that it doesn't bulge.

This might sound stupid but whats the point to spend 100$ on a wireless charger ? Does it really bother you that much to have a cord laying around ? I find it not very conveniant at bed time... /unless its because you need some juice and there is no power source close to you i understand

One advantage is that the micro USB connectors are a weak point in the design of most cell phones. They often break or wear out. Given the extra contacts in ours, I like the idea of avoiding the wear and tear.
But it looks like this one doesn't follow the Qi standard which our phones support with the replacement back which was promoted so I'll pass.

If you look at duracell's page closer, 99.99 is for a S3 "kit" , which :
Includes:
(1) Powermat® for 2 Devices
(1) Wireless Case for Samsung Galaxy S III
(1) Power On The Go
(1) Universal Power Supply (100-240VAC)
(1) Owners Manual
You can also buy the case, powermat or portable battery seperately. The bulky wireless case is 34.99 , the 2 device powermat is 49.99 and power on the go is 49.99.
I'd prefer changing only the backplate instead of having a case around it, but I guess that if you only change the backplate and put a cover on top of it, it could very likely interfere with the wireless charging being to far from the charging mat.
Samsung's own wireless recharger should be available soon somewhere, and supposedly has coils 40 percent thinner than other charger out there, keeping the backplate as thin as possible. Although, I expect the price will be high. I am pretty fed up with all the asian designed cheap accessories ordered over the net for a fraction of the price.. so I wouldn't mind spending on something that i would use as often as a charger.
99.99$ could of been a deal, if the case wasn't so damn huge.

If they would have made a blue or black version I would buy this. Can't see putting a white case on my blue phone.. ugh

Still have to provide power to the wireless charger. Fail.
I'll keep it simple (and stylish looking... man that thing is an eyesore) and plug a cord in

I don't consider it wireless charging if we have to have a gigantic bulky ugly case to do so.

Here's a link to give you a better idea of a DIY wireless charger.

My solution
I guess }{Alienz}{ isn't going to reply. I'll tell you what I did for my wireless charging needs.
I purchased the Palm Touchstone wireless dock from Amazon for about $8 and a new SIII back cover, with a touchstone compatible module to charge the battery, from e-bay for $29 (the scumbag I bought my case from is now selling them for $99) Put that cover on my phone and it looks and works like normal (including NFC), but I can now charge the phone by just putting in on the Touchstone.
Works for me and $35 is hell of a lot better than $80-$100

That's real nice and really simple to implement unlike the hacks I've seen from a few month ago. But the hacks are cheaper, lol. It may even work with the flygrip I have attached to the back of my phone. It's just at 5mm.

Wireless charging compatible cases

Hi all,
I've been reading a lot of threads about wireless charging and one of the most frequently asked questions is:
"Does this work with my [insert case here]?".
Click to expand...
Click to collapse
So I thought it would be a good idea to make a thread where everybody can check if their cases are compatible before they actually buy the kit.
The 'set-up' I'll use for the testing will be this one; this backcover and this touchstone.
(Please note that I'm not affiliated with any of those products nor sellers. I'm just a guy that's trying to help his fellow S3-owners out before they buy the kit/mod. Those products also were the cheapest ones I could find on eBay as of 27th november.)
I will divide this into 2 sections; the QI wireless charging and the Touchstone wireless charging (mod).
I've ordered a couple of cases to test out and I will report back later. Also, I'll probably give these cases away afterwards anyways.
In the meantime it would be great if people could add cases that are compatible and if they use the QI or the Touchstone wireless charger.
QI wireless charging compatible cases:
-Otterbox Defender
-Otterbox Commuter
-Otterbox Prefix
-Spigen SGP Neo Hybrid
-(some) TPU/Plastic cases
Touchstone wireless charging compatible cases:
.

I've added a section like that on the stickied qi thread as well [last night]. (in my post that is).
Specifically for the Qi ones. Afaik, members who have the otterbox commuter & defender are able to charge w/ the Qi charger.
I have a hybrid tpu/plastic case that also works with the qi kit.

Alright, thanks for your input. Do you want me to delete the QI piece? So there are no double posts and whatnot.

I don't really care. I think it's fine to have a place to double check.

i just manage to put the Touchstone wireless charger from palm into the galaxy s3 battery cover, ordering some case on amazon, will report back.

Since this thread is about Qi & Wireless charging tech.
Why not link to where we can get a battery back with the capability to wireless charge our phones? just a thought.
I've brain stormed ideas including ways to add a wireless charging station to a car/truck but I have yet to get a wireless/Qi battery door to make it even possible to start doing such experiments.
I had heard Samsung announced a wireless charging kit for the S3 but apparently never released it. (hopefully they show it off this week at CES for release alongside the new Extended battery coming this month)

check my 2nd post in the sticked thread for different options. That was all I was able to gather before it got close due to some members who blatantly abused the thread for their personal gains.

Are the Qi backs compatible with the Nokia wireless pads? I read some threads on here that some users are using them but wasn't sure if that was entirely true and if it worked or not.

they work. It's a qi reciever so any transmitter will work. (i have the yijieneng one and tested it out on the nokia pad and the speaker/charger pad combo at the AT&T store and it charges just fine.

Received my cover a while back. Also ordered 2 touchstones and *about* 20 different types of cases from different locations.
Was on holiday and didn't manage to get home yet but tonight I'll try everything out.

Alright, will add this in the OP.
FYI, I bought this backcover and 2 of these touchstones (note: doesn't come with a cable or anything; just the touchstone).
Also, haven't had a chance to try the combo out -yet. See previous reply.
Yeah, they announced it but haven't released anything yet. Frankly, I don't even know if they'll ever release it. Maybe it was just for the hype of it.
After all, they were 'one of the first' that would incorporate this in a device so widely sold.

I have the Zens white backcover with the Zens charging pad. It works but the cover is too thick for use with my case (which i want to keep) + it's white (Black S3).
I was wondering if anyone has experience with dismantling the tech in the zens cover and 'mounting' it in the standard samsung cover. Any feedback is welcome before i rip it apart

I got this touchstone back;
http://item.mobileweb.ebay.com/viewitem?itemId=170950767865
The magnet is terrible, it can barely stay on the touchstone without a case on it, and let alone with a case.
I have a touchstone on my dash in my car and even when driving slow in a straight line with no case on, the phone won't stay on the touchstone.
This Sucks because I bought sygic gps and was hoping this could replace my windshield mounted deactivated HTC touch pro 2 with igo8 finally.
Has anyone got one with an acceptable strength magnet?

Question regarding Galaxy S3

Hi I am planning on purchasing the Palm TouchStone wireless charging kit for my S3 i747m from eBay
http://www.ebay.ca/itm/281051460427...eName=STRK:MEWNX:IT&_trksid=p3984.m1439.l2649
Does anyone who have the mod or an eBay kit tell me if the magnet attachment is on the TouchStone charger or is it on the Phone battery cover or both?
Also, how fast does it charge with the TouchStone?
Does it overheat after charging for a long time?
Does the TouchStone charger "turn off" or switch to "tinkle charging" after the phone is fully charged?
Any answers to my question would be highly appreciated.
Thanks in advance.

Anyone can help?

I would look for a touchstone forum or review site for answers, not here, bro. There is an accessories thread you could possibly get an answer in.

I had seen a YouTube video where someone did this to their s3! Check there!

I see, I will take a gamble and buy it... rated at ~500mAh with coil and charger directly aligned.
With my Otterbox Commuter case, I think the charging should not be affected too much (my guess is around 480mAh-490mAh)
This is because the Touchstone, like the Qi, is using EMR for coil and charger transmission/receiving. The only different is that Qi and Touchstone operate at different frequencies and the coil designs might be slightly different to have either slightly better range or better efficiency.
From my experience with Wacom tablets (Intuos, Bamboo) and Wacom integrated tablets (Galaxy Note 10.1, Note 1/2, Tablet PCs, Cintiqs etc)
The pen can hover even with an overlay sheet or a pane of glass over it.. The hovering range is around 5-7mm depending on how thick the surface cover is.
Hopefully the charger has a built in tinkle charging mode and a auto shut off mode (the phone power management should have this)
Also hopefully it does not overheat the phone when it is charging through my Otterbox Commuter case.

Wireless charging confirmed working on our T-mobile S4

Hey guys, don't know if people have done this already, but I just got a T-mobile S4 for testing this weekend and I wanted to find out if the wireless charging port was enabled since I've done the touchstone wireless charging mod on my S3 and note 2.
It was especially a PIA on the note 2 since T-mobile, in all of its corporate and engineering wisdom, decided to disable the feature for the Note 2, even though it was enabled for the S3. So for those of you who don't like to dissemble your new phone and solder on a tiny PCB, you'll be happy to know that I confirmed that wireless charging ports on the S4 is indeed enabled.
I took a pack of 4x AAA battery assembly, which provides ~4.7v of DC power, and connected to the charging port in the back. The small pair on the left is the charging port, the pair on the right is supposedly NFC, even though the NFC antenna is located on the battery for S4.
As you can see from the pics, the "the phone is now charging wirelessly" notification pops up when the circuit is live, which is pretty annoying IMO and can't be disabled (that's why we have custom roms right?)
I haven't gotten a chance to install the actual touchstone wireless charging receivers on the back yet, as this is a test unit that I have to return, but I don't imagine this to be too different than on the S3. There will be a slight bulge, but it'll be worth it.

Just follow the instructions from this thread (it's for an S3). The design for S3 is pretty similar, so it should work. Remember the positive pin is on the left, negative (ground) is on the right.
Also note that the touchstone mechanism is not Qi compatible, so it wont work with the newer charging mats for Nokia or HTC.
And always remember to perform these mods at your own risk.

Did you install any receiver on the S4?
I didn't mean to confuse anyone, I only confirmed that it is POSSIBLE to perform the mod. I used a 4.7v DC power supply to test if the wireless charging pins on the back are live, which wasn't the case for T-mobile note 2 so I had to check to make sure.
If you already have a Qi charger, you can get one of these receivers and connect it to your phone, then you'll be able to charger with your mat
http://www.ebay.com/itm/qi-Wireless...l_Phone_PDA_Chargers&var=&hash=item51abef6de9
But I would argue that the touchstone method is superior to qi if you plan on using it in a car, as the magnets keep the phone in place is it's really convenient to connect/disconnect when you're driving.

Samsung will be officially supporting wireless charging for the S4 through accessories. The ad for the pad and back wireless charging cover is already listed on the promo S4 accessories page. http://www.samsung.com/global/microsite/galaxys4/
Though there seems to be no price or date yet.
Of course there will be 3rd party wireless charging solutions as well.

also;
can anyone confirm or deny wether or not the palm touchstone + receiver will trickle charge the GS4 after it is fully charged ? (or does it completely cease charging until the phone is physically picked up and replaced ?)

It seriously only took 5~10 minutes once I'd figured out which way to put what.
I have the photos set up and just need to put notes on them explaining what I did.
Will post them when I get home tonight (12am CT)

Ummmm, from everything I read the pins you have it hooked up to are NOT the ones for inductive charging, the gold ones on the right are......
I could be mistaken however. I remember the s3 used those pins, but I've read in a couple places that the ones made specifically for inductive charging are the ones on the right above the battery.

What ARE all the other pins back there for? I figured one set (had no idea which one) was for inductive charging, but couldn't figure a reason for the others..

the smaller set is wireless charging, the larger set is presumably for additional NFC antenna (although I measured no resistance in the circuit with my voltmeter), as the back cover seemed to have a carved out area for a NFC like the Note 2 did.
Although the S4 battery says "NFC" on it, which seems like samsung made a last minute decision to put NFC on the battery instead of the back cover... oh samsung ¯\_(ツ)_/¯

Nope, the NFC is in fact in the battery, the same way Samsung has been doing it for years now. They made no change.
Oh false information from people that don't know what they're talking about ¯\_(ツ)_/¯
