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...

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.
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.
Wouldn't be a very good accessory a slim protective case that can charge the N5 wirelessly via Qi and get cahrged using the same tecnology?
This would not make the case huge increasing height and with but just thickness, as there would not be the need of integrating the micro usb port.
I think that a slim 2 mm 1000mah would be perfect.
I'm talking about something like this for HTC One Max, with Qi instead of pogo pins.
Is it in your opinion possible?
Would you buy it?
I'd buy it for <50$ USD

Possible? Yes. Worth it? No.
Qi is expensive, the case would need to be 90-150 dollars depending on a number of factors.
Qi is inefficient, you would need double or triple the capacity battery vs the amount of charge you would actually get to the phone. This means 2000-3000mah batteries for 750-1500mah charges. Huge thickness increase. Your example battery would provide sub 500mah actual charge to the phone. Best case scenario for Qi is 70%, from my research.
When you're discharging one battery, there's a heat cost. When you're wireless charging, there's a heat cost, and when you're charging the other battery, again, more heat. All of this made worse by the fact that it is significantly less efficient. I don't know enough to say if the heat would be totally limiting as in impossible..But I do believe overall battery longevity would be degraded by the heat, and it may even be impossible to do in warm climates.
The pogo pins are the way to go for this. Anything else is too inefficient or bulky. Unfortunately, those have to be put in from the factory.

I'll never stop shouting why Google left (some of) us 5$ and 700mah far from having a perfect smartphone!

If any of you guys used any of these, what is your experience with it? Also if you could provide info on whether or not the Nexus 5 will stick on there until a certain angle or will it slip right off even if you move the charger around. Asking this because i'll be using it in the car also.
Thanks
I have the Lugulake one. It's good, works well, charges the phone in a very similar time to the wall charger and has a decent grip on the phone, not sure how good it'd be in car tho. But.... I also want one of these which I'll be ordering soon for the car -

I think both of those devices are available on Amazon and for under $50. I'm thinking of getting the first one. Vent mount and I can use my SGS3 with it.

I have one I got on ebay that is 10,000mah and looks identical to the first link. (http://www.ebay.com/itm/141047804367) It cost $37 (looks like the price dropped a little since) and so far I'm very happy with it, though I've only used it a bit when traveling. It does take a while to charge since 10,000mah on a 1A charger is 10hrs. I haven't really carefully tested its functionality though. I wonder if its current discharge limit is lower than it says, though, since I noticed when I had my n5 plugged into it the 2.1A port and under heavy use (games) the phone battery didnt charge, it only discharged slower... I'll have to test more.
