Hey all, I just noticed that the official Powermat back battery door for the MT4GS is on sale at T-Mobile for ten bucks. You'll still need the actual Powermat charger, which goes for $20-30 online. The website also charges shipping and sales tax, FYI. But still a good price:

great find, is it only in black?
These are highly worth the money, it charges the phone much faster and is nice to not "plug" my phone in..
Got one for xmas and works amazing..

my battery door just **** the bed, so this is a godsend!
Case that fits?
I just got the PowerMat and battery door when I upgraded on Saturday. I love it, but I can't find a case that will fit over the slighty larger than normal battery door. Has anyone else had luck finding something that works?
Where's the best place to get a single position mat? Best price?

I looked around Amazon a little bit and saw plenty of single-position mats for a particular device, usually including the receiver door for that device, for under $10. (You know, for a device that you don't have. ) Here is one example (for BlackBerry Bold 9700): http://www.amazon.com/Powermat-Position-Charging-BlackBerry-Receiver/dp/B00462QB4C
It looks like these mats have a custom indentation to hug the back of the device, so it's unlikely to be a perfect fit. Also, if you device doesn't fit into the indentation, it might not charge.
But ... cheap! Most of these are not Amazon Prime eligible, so it costs another few bucks for shipping.

I'm sort of inspired by this thread to try hacking some powermat chargers for some other phones where the receiver is still expensive or there just isn't a receiver. If you search around, you can find some reports of folks who have done this with varying degrees of aesthetic sensibility in the results.
One idea, that I kind of like a lot, is to use the Palm Pre charging "Touchstone" as the transmitting mat. Because the Palm Pre was kind of a dud in the marketplace, the Touchstones are available for pretty cheap. Here's an example at Amazon for under $5, including shipping: http://www.amazon.com/Palm-Touchstone-Charging-Dock-Pre/dp/B002CMEIWK. One hitch with the Touchstone is that it uses a couple of magnetic thingies to activate it (and, I guess, hold the device in place). I'm sure one could deal with that somehow.
Thanks for the last post.
Alright, I'm totally confused. I took a look on Amazon earlier this week, but without confidence in the mat actually working with the device perfectly, I decided to check out what was in stores.
I go to Best Buy and couldn't find them. I asked an associate and they said that they no longer are carrying PowerMats because of the shorting out risk.
Ummmmmmm, okay....
I go to Radio Shack and the associate there starts talking to me about two different types and how one doesn't charge fully all the time and that kills your battery over time and the other involves walking around with a "puck" on your phone.
What the hell is everyone talking about??? I thought these were pretty good and I'm reading nothing but nice reviews online, with the exception of the expense. Frankly, at $10 plus shipping for the case, I no longer care about the expense.
Thoughts????
I don't know anything definitive about most of that. From poking around today, I've deduced a few things (none of which involved "shorting out" ).
Powermat and Duracell both made something that looked like roughly the same technology. Some time in the recent past, Powermat and Proctor and Gamble (who I guess own the Duracell brand?) formed a joint venture or some marketing agreement to make and sell "Duracell Powermat" devices.
The mention of a puck thing could mean either of two things. First, Powermat sells a "universal" receiver, which is a little block with the inductor coil inside it. You still have to connect it to your phone's charger port via mini/micro USB (or one of their other tips). Of course, you wouldn't have that on all the time, except when you are charging. Second, Duracell sells or used to sell a gadget that semi-permanently plugs into your USB port and then sticks to the back of your phone. The latter sounds like what the RS guy was talking about.
After a couple days out of town, I returned to find a bunch of packages of el cheapo Powermat stuff for experiments.
I got a single-position mat specially intended for iPhone 3G and 3GS from a 3rd party supplier on Amazon for $7.44 (and free shipping due to Amazon Prime). With the MT4GS Powermat receiver cover from T-Mobile, I can charge using this mat. It's not a perfect fit. The mat does have an indentation, but it's not for the iPhone. The included iPhone case has a rectangular hump on the back, and the indentation is for that hump. Still, by wiggling things a bit and placing the MT4GS off-center, it does charge. The MT4GS cover does not have that hump ... it's just slightly thicker than standard overall.
From the feel of things, there must be magnets that activate the mat. So, I had to fiddle with the placement of the phone to get the mat to turn on. Once it did, the charging light came on for the phone.
(I haven't taken any of this apart yet, so I'm speculating a little.)
On spec, I bought a Palm Pre Touchstone charging kit. They are pretty cool looking and are available pretty cheaply. (Mine cost less than $10, and I've now seen them for $4.) Alas, the kit include the charging dock (which I hope turns out to be compatible with Powermat) and a receiver cover for the Palm Pre (yawn), but it turns out that it wants to reuse the power cord from the original Palm Pre charger.
It looks like it's a mini USB connector (though it could be micro USB), but it fits into a pretty cramped tunnel in the charging dock. None of the USB cords I have on hand will fit all the way into that tunnel.
So, that's a bit of a bust, but I reckon I might buy a Palm Pre power supply since they are also pretty cheap. The looks of the Touchstone are so cool, I hope I can get it working with my MT4GS.
Anyone interested in one or two of these?
Sorry to Necro this thread but has anyone gotten this door to work with Qi chargers? I suppose it won't work out of the box but I can imagine switching out the coil with one for like a SGS3 or some such.
I plan to buy a wireless charging chip and stand for my gs5. I leave a otterbox defenders case on my phone at all times because I dont want to lose her.. My question is that will the wireless charging work through the case? Or do i have to take the case off every day. And i have no idea which chip and stand i will buy yet. Here is a link to my case I use. thanks. http://www.otterbox.com/Defender-Series-for-Samsung-GALAXY-S5/sam2-galaxy-s5-set,default,pd.html
There are several threads detailing wireless charging, I suggest you look into one of them.
Short answer is the charging can work through the case. Long answer is your milage may vary.

Maybe. The only people that can really answer your question are those who own the same case as you and have tried it. Or maybe a well written review that tests charging through thick cases if you can find a review that does that.
I don't own an Otter box and you didn't give us any crucial details e.g. how thick the thing is? But my impression is that you own one of the larger, thicker cases. The current chargers work through thin cases but a lot of people with fortress type cases have reported problems. Not to mention that it depends on what brand of charger you have and several other things. I'd say it's iffy, actually I'll venture that it won't work with some charger brands. But if you find a better than average model you may be okay.
Advice? Either buy locally where you can presumably test whether it will charge through your case in the store. Or buy from a mail order vendor with a good return policy and test it first hand.
And just to complicate things.. you should know that there is a battle in progress between several incompatible charging technologies. Most of the current wireless chargers use the Qi system. And Qi really isn't designed to charge through thick cases. But there is an underdog called PMA aka Power Matters or Powermat that use a different technology. Resonant, rather than inductive charging. And it is said to work fine through thick cases.
So regardless of who ends up dominating the market, I'd try to buy a Powermat or PMA product if the price is similar. Keep in mind that you can't mix and match. The piece that goes inside your battery cover (or is built into the cover) has to match the charger. Both need to be Qi or both need to be PMA to work.

Thank you so much for the detailed reply!
Sent from my SAMSUNG-SM-G900A using XDA Premium 4 mobile app
This is a quality product from Choetech. I received my review unit and overall, it far surpassed my expectations. Here are some things I liked/may not have preferred:
Pros:
1. Stylish, sleek, elegant design
2. Minimalistic yet effective packaging
3. The cord fits in my microUSB with a Spigen case no problems (for those with Spigen cases, you know the port cut out is quite tight and most cords are too big to fit without taking off the case
Cons (specifically related to my PERSONAL preferences):
1. The included cord is not as long as the original OEM Samsung cord which tends to get difficult to maneuver when I'm charging the device and using it in bed.
2. The USB input port on the wall charging puck is place on top which causes the cord to bend to the left while I'm laying in bed. This could eventually damage the cord due to prolonged bending.
Overall, I am very pleased with this product and I would definitely recommend their products to others.
I tested this charger with my phone and 2 Kindle Readers. Everything charged very quickly but the Qualcomm compatible phone which would ordinarily take 2 hours and 20 minutes to charge from the 40% level on a standard charge, took about an hour and a half with the CHOE charger. http://www.amazon.com/dp/B00QTJZ3D0
Adaptive Wall Charger is awesome!
Those charger works great with all of my Samsung devices. I've got the Note 5, S6, and 2 Galaxy Tab S2 tablets. I've got link to my video review of it below.
https://youtu.be/GV9o1xeVNdw
Sounds good, fitting with a Spigen case is a plus because I always order chargers that have wide rubber (aux cords too).
Got in the LG OEM wireless charging back today for the V10. It is of very nice quality and maybe only a hair thicker then stock back, very hard to tell. I don't think there will be any problem fitting into standard cases.
I got it for the everyday low price of $79.00 plus shipping from Amazon.
Only has LG and not V10 on the back corner.
I've add a few pictures showing it side by side with the stock back.
Very cool but also a bit pricey but it's LG oem so your gonna pay a bit more bought a cheap back cover from china with wireless charging that works well only paid about 15 bucks it has a leather back and the fit isn't quite as good as the stock back if you have the money I would definitely get the one you picked
I've used both Yootech and OEM. OEM charges quite a bit quicker and with less heat.
Thanks to the OP's for the information and photo's.
It isn't going to be much different in the quality of the charging, the only different is the built quality, the QI and PMA circuit (PCB) is in the phone, the back cover only contains the coil to complete the wireless charging part.
The current coil use for both the OEM and third party is a flexi coil, isn't the best, it's used because it's thin, I'm going to mod mine when I get the V10 within the week, and put a proper copper strand wire coil, has better detection, less heat and less transmission loss.
I have a few types of coils made especially for wireless charging, and will post back.
you can just buy the Qi receiver sticker for less than $10 and apply yourself.. why would anyone buy this for that price?

That doesn't make sense, the charging hardware is already built into the v10, 3rd party including OEM is just a coil and connection to the pins. Which should not make a difference in charging speed or heat. Only thing that might affect that is placement and alignment of the back of your v10 to the charging pad..
What are you using to determine charging speed and heat?
EDIT: Attached is my Brown Leather Back with NFC/Qi sticker. (btw is that the British way of spelling chargeing?) I've also ordered NeWisdom's sticker, will review once I get it in and on.
Where did you get the leather charging back from? Is it much thicker then the stock back? Please let me know how the NeWisdom sticker works out. Was going to order one also.

You are correct to a certain point, both OEM and third party uses a flexi coil with a flexi magnet, the quality of these also determine the detection and aligment.

There on eBay just search connection station on eBay around $15 four different colors there slightly thicker than the stock back you can tell the difference by the volume buttons but not too bad a fit though
I just received my leather back with wireless charging from eBay today and it's not charging at all, is there some setting I need to turn on? I'm using an official Samsung qi charger btw.

There are no special settings that I'm aware of.
I'm fairly irritated at LG for the glacial speed at which they're releasing official accessories for the v10 . . .
Now that that's out of the way, I bought this: http://smile.amazon.com/gp/product/B017R40JRA?psc=1&redirect=true&ref_=oh_aui_detailpage_o00_s00
It's already unavailable (which isn't terribly surprising). It is just a little too thick, which pops the case up a bit over my power/volume buttons (so they're annoying to use). Also, it's pretty much stopped working. I might try to realign the thing, but it worked fine for both NFC and Qi (TYLE Vu) for the first week or so. Now it doesn't reliably charge (though NFC continues to function).
All-in-all, I'd rather pay for an OEM cover, where I SHOULD have to worry less about alignment and having a poor fit.
I'm curious about the NeWisdom though . . .

I liked the wireless charging on my nexus 6 so when i bought the V10 i had to get wireless charging working on it so i bought the leather qi/nfc back for $15 of eBay (connection station) and it works very well with the Anker qi little disc charger i bought off Amazon but the leather back doesn't fit exactly as good as the stock back there's that little gap by the volume buttons you described but worth it to have the wireless charging working
Yeah, I'm going to give it a few weeks--hopefully the stock one will come out (a more reasonable price would be nice too), or someone will come up with a back cover that's a better fit. A guy can dream, right?

GSM and the fact that it literally takes twice as long with the Yootech. So a watch is what I'm using to determine the speed. It can and does make sense as it depends on the conduction of the materials used. If yootech uses different metal composition in the coil then it gives off more heat energy and doesn't charge as fast. Welcome to physics.

That looks pretty nice. Check out my cart here, you can see all my goodies. I'm going with an off brand Spigen clone because I like to use my phone wile it's on the dock and this one looks more stable for that.
I am planning to go with the Yootech back cover. Hopefully it's wont cause the phone to get warm like some others seem to be saying...
For the OEM back, is it able to trickle charge at 100%? On my Nexus 5 at 100% it would just trickle charge and stay connected and cool while keeping the battery full. With my qi leather back I got, it hits 100 disconnects and then reconnects in an endless cycle randomly waking my phone up and keeping it warm. Sometimes my Tylt clone will just shut off completely from the cycling which isn't conducive to having a topped off phone for overnight charging.

Bought a little Anker qi disc charger of Amazon for $12 it claims that it regulates the heat and that it doesn't waste energy overcharging i just put my phone on it when i go to bed wake up and it's at 100% and my phones not hot the charger has 2 led's blue when it's charging and red and blue when the phones charged
This wireless charger is one of today's deals on Amazon: http://www.amazon.com/Anker-Wireless-PowerPort-Charging-Qi-Enabled/dp/B00Y839YMU/ref=dp_ob_title_wld
I've heard a pretty substantial amount of good reviews for this charger, so I'm thinking of picking it up since it's only $15. I was also looking into getting an OEM LG wireless charging back, but I'm not willing to pay $50+ for it. Ran across the NeWisdom Qi sticker and it seems to have mixed reviews: http://www.amazon.com/NeWisdom-Wire...sr=8-1&keywords=lg+v10+wireless+charging+chip
Was wondering if anybody has had experience with the NeWisdom Qi sticker. Any overheating? Went bad after a while? Ect.

So i bought the new Wisdom sticker off Amazon. I'll say this--i used a hair dryer as the instruction indicates--and peeled the original NFC only sticker off (or so i thought) and applied the new wisdom. It would register like it was charging but not actually charge as dr_w indicates above.
HOWEVER...frustrated i looked at a couple videos and noticed that the battery doors with the sticker fully removed didn't look like mine. With an exacto knife i picked at the remaining black area only to find there was still copper wire underneath. In effect the original NFC sticker had multiple layers and i'd only peeled off the top. Getting ALL of it up was a challenge...like a real challenge...it did not peel off i had to scrape with a knife for an extended period of time.
At the end of the day though once i had the original sticker all the way off i reapplied the New Wisdom Sticker (which surprisingly survived multiple attempts at reapplying without ill effect). Then setting it on my Spigen charger stand and running the Ampere app i was amazed at how well it was charging. It actually was over 1000ma at one point and after finding it's range (it starts low and builds) it averaged at about 800ma. That was decent enough to charge my phone pretty quick. For reference fast charging is like 1350--1500ma or so. In comparison the Monroy wireless back i bought from Amazon that already had a sticker applied (presumably NOT New Wisdom) typically does maybe 350-500ma.
So the bottom line is it was WAY more of a pain than i anticipated but now i'm stoked and actually rather impressed with the performance.
LEt us know if its consistent. I've had a very similar experience before it began discharging at a rapid rate. Thanks for the post, I'll keep checking back.
Originally had a cheap sticker off eBay that lasted several months, about 3,then the chip in the phone caved out. Got the newisdom the other day and got a Tylt charger to go with 2 Samsung fast chargers and no issues so far. The constant lighting up the phone when it's charged is annoying and the g4 tweaksbox doesn't seem to fix it.
I'm using the OEM LG wireless back and it's quite nice. Feels exactly like the original and fits very flush, no problems with wireless detection on my TYLT charger. I'm actually surprised at how little the back weighs as my understanding is the copper coils should add some noticeable weight but in this case it doesn't. Maybe not that much copper in these OEM backs?
Just ordered an OEM wireless charging back for my V10 (a seller on Amazon has it for $29.99 atm though no prime shipping with the fastest option being expedited shipping) and due to the price, I'd imagine it already being sold out by the time this post is read. I didn't want to get the third party stickers as I want to keep my current back and the third party plastic backs are pretty horrible in terms of feel and fit.
Anyways, what do you guys recommend for a good wireless charging pad? The official Samsung pads look interesting enough as is and I've seen it work with every device with Qi built in or using one of those plug-in Qi pads you place inside a case before the phone though I'm gonna have to wait til my next paycheck to get a pad: already spend a good chunk of cash on an MSI RX 480 and only bought this back due to the steal of a price at $29.99, $36 with expedited shipping. It was that or go with prime and spend $60 on a back
Finally received my OEM wireless back. As expected, the battery door feels exactly like the original back albeit curves near the button cutout due to the extra elevation it adds. Also makes cases a tighter fit if you're concerned about compatibility. Works on my Yootech wireless charger as well as a friend's Samsung wireless charger and Tylt Vu 3, the last two having the best range in terms of surface since the Yootech seems to only have one coil. As for charging, going from 0-100% took about 2-3 hours and the phone got pretty warm too though just a smidgen cooler than it gets when quick charging via cable. The packaging DOES have the description for what would've been a wireless charging variant of the Quickview cover which would attach as a battery door too but I guess that didn't work after all the hullabaloo about the faulty Qi chip. Sucks that the LG logo simply takes place of the rather sexy V10 logo
Either way, I'd recommend getting an OEM back when you can though might wanna wait. Some listing still sell it for $60 a pop and even $100
