One of the things I was really excited about with the Lumia 920 was the built in wireless charging feature. Since the Nokia charging plate was selling for about 70 bucks (ouch) I decided to see what alternatives were available. I've tried two different wireless chargers so far with mixed results:
LG Electronics WCP-700 - This charger works great and I was able to snag it from amazon for 35 bucks shipped. If you want wireless charging but don't want to pay 70 bucks for one charger, then I highly suggest this model. You can get 2 for the price of one Nokia Charger.
Powermat 2x - I was hoping the community could give me some advice on the powermat. Naturally if you plug the powercube into the phone, it will charge just fine. BUT I noticed that if you put a charging plate on the charger and then put the 920 on top of it, the 920 will begin to go into charging mode, although when i tried doing that, it didn't really seem to be charging at any noticeable rate( I may have been taking the phone off the charger too frequently though). Does anyone know exactly what voltage and amperage the powermat wirelessly charges at? My concern is that the volts or amps will be off and damage could be done to the battery in my lumia 920. Any thoughts?
Good questions! I was wondering the same thing about the different mats out there.
What about the Energizer one?
Also, the LG one apparently beeps a lot...does it do so with the Nokia? When it finishes charging it turns off and lets the phone run off battery for a bit, then turns back on to top it off again, causing it to beep each time it turns on throughout the night. Have you noticed this?

From what I've read, the Energizer QI chargers will work fine with the 920, I just didn't get one since the LG model was a bit cheaper. The LG one does beep, although I haven't found it to be too much of an issue. When I place the phone on the charger, the LG mat will beep and show the green charging icon, and my phone will make the connection noise. I also think the mat will beep occasionally when the phone is charged, since it lets the battery drain a bit, then starts charging again, although last night it didn't wake me up at all while I slept. You could probably remove the speaker from the LG pad fairly easily, although from my experience, it's not bothersome enough to be worth the trouble.

Doesn't the PowerMat use a different wireless charging standard? I thought I read somewhere it wasn't the QI standard.
PowerMat is its own standard.
Not sure where you are, but the plate is $50 and the stand is $70 here.
Might want to try mail-order?
As for other plates, I have a few lying around, but I don't want to risk my phone trying them without knowing. I have 2 plates and a stand, so I am pretty covered.
Philips DLP7210B/10 also works with the Lumia 920.
I ordered a Palm Touchstone off Amazon for $6 and free shipping. I'll know in a few days when it gets here if it works or not, but I read somewhere that it should.
Sorry to disappoint you, but the Touchstone does not work. It makes the charging notification sound, but the battery still drains; it doesn't charge at all.
I have the Maxell Airvolt QI charger. It works but the phone seems to get warm unlike the Fatboy charger I use at night.

Doh!
I really hope someone makes a 12v charging pad to keep in your car. Plug into the cig lighter and lay the phone on the "pad" somewhere in the car. I know the new dodge cars have it as an option now.

There's no reason why a 12v adaptor of sufficient ampage wouldn't work. Just match up the plug and polarity to the DC adaptor that comes with the charging pad.
But obviously a QI charger is not designed for use in a car. QI only recently release their guidelines:
http://www.wirelesspowerconsortium....ermarket-chargers-v-10.pdf?force-download=yes
It seems there are two current wireless charging standards: QI and PMA
Powermat are PMA, and this is a copyrighted licensed standard, i.e., Powermat will get revenue/license on each device. There is a limited trial in Starbucks.
QI is open, and I think a "free" standard. They have public charging spots in Japan, and Japanese handsets are predominantly QI
This is all just what I've recently read, so I'm not an expert or utterly certain it is correct, but it does seem that Nokia 920's are to the QI standard, and so any QI charging plate should work...?

I personally plan to do just this. I figure a Qi compatible charger hard wired into the car, then find a good place to mount it with a thin grip pad covering it. It should work just fine.

Ooooo, my Edge has a little 'shelf' under the console that has a ribbed rubber bottom. And it has a 12v plug right beside it. I bet my husband (the engineer) might be able to wire up a charging plate. He would need to shorten the cord so it wouldn't flop around. But he's very good at that sort of thing.
This is a great idea! He works overseas but I think I have a new 'honey-do' for him on his next R&R. Thanks!

Anything that is a Qi charger should work, it's a standard.

I have an Everyready Qi charger, the 920 and it are happy as clams together.

Nice! I'll get one too!
tabletop charging
I personally think it would be awesome to be able to integrate QI wireless charging into a tabletop. think about it, when you sit down at a table for dinner, you usually take your phone out of your pocket, right? what if you could charge it while you eat? why doesn't starbucks do this?:highfive:
Hi guys. I bought my G3 few months ago. Its not a new one, I bought it as second hand but condition is 99,99%.
As the information I got from the seller its D855 Vodafone - International.
So my question is as those images i shot on my back case is this true that my phone can use with a Qi charging pad right away now or not?
Because after searching through the net, I didn't find any information about Qi charging relate to G3 Vodafone.
The receiver on my back case has 4 pins (as I know 2 is for NFC, and the other 2 will be for Qi charging).
The problem is I went to other shop (not really a shop, this guy just shipped items from China), he was selling some Qi charging pad. I put on 1 pad there but nothing happen, try many angles but still the same.
So whats the problem, my phone or his pad?
And here my back case. Thanks for your feed back and sorry for my bad English:
Yes, it should work.
If it doesn't work with the Chinese charger it's because the charger...

Make sure the golden square hits the ones on the back of the phone
Is there anyway i can get qi wireless charging on my f400s by buying a back cover which supports qi?
Qi works out of the box
Yes your G3 should be Qi compatible out of the box...I have a Panasonic, and Nokia Qi Charger, and they start working about 2 seconds after I place them on the charge pad.
Just FYI, the G4 on the other hand isn't Qi Compatible out of the Box...Go figure, I guess Quick Charge 2.0 is the better standard...=(
So I've been able to test out this nice USB car charger from Choetech Official with Qualcomm 2.0 charging capabilities. And I must say this lil thing works very well. Charged my Nexus 6 up from 15% to 73% around 45min. It's a well built charger that has smart technology for recognizing what kinda devices you have plugged in.
Has a dimmed LED that changes from blue to green when you plug up a fast charge device.
It's a dual USB port charger.
Input: 12-24V
Output 1: 5V 2.4A
Output 2: 5v 2.1A/9V 1.7A/12V 1.3A
I really like this unit. Works better then the crappy one i used to own by Qmadix. That one always seem to stop working after 2 weeks of use.
[Quick Charge 2.0 Car Charger]CHOE 30W (with Most Powerful QC 2.0 Port) Dual USB Car Charger with Micro USB Cable(White) https://www.amazon.com/dp/B00YX7Y3G8/ref=cm_sw_r_other_awd_GxKlwbPTT27F2
PS. the Choetech C0046 does come with nicely built 3ft USB cable.
I received this charger couple weeks ago and have been using it. The charger arrives in a nice package with the standard accessories. Inside it has the charger, the usb cable, instructions manual, and a pamphlet that ask if you're happy with the product or not. Pretty standard nowadays. I got the black charger but they also offer it in white. The charger is shorter than my other ones which is a plus for me. I don't like them to stick out of my car port since it's really close to my shift knob. The charger comes with two usb ports. 1 is for quick charge 2.0 for some phones like my galaxy note 5. The other is a normal port that charges pretty fast too, up to 2.4 amps. You can use either ports to charge your devices and they will charge to the max allowed but if you have a quick charge 2.0 enabled device, it's best to use that port. They colored the port blue for fast recognition which is nice. I don't have to fiddle around with it while I'm driving to figure out which port it is. The quick charge can charge my phone from 50% to close to full in about 45 mins. It takes longer if the phone is being used. I use the charger daily during my drive to school. I always charge it up to 100% before I head to class so it can last me all day. I was worried that by using quick charge so often, it would deteriorate my battery life but I haven't experienced that yet and hope I never do. When I use the charger to charge 2 devices, they both charge at their max. My phone charges with the quick charge while the other phone charges with the other port and it doesn't affect each other, which is very good. I really love this charger. If Iphones had quick charge, I would buy this charger for everyone in my family.
Choetech also was nice enough to allow me to test one of these charger for them.
I found it to be an excellent charger.
I have copied my review from amazon here for the fine folks here at XDA.
I will try to answer any questions you may have, just post up a reply or send me a PM.
--------------------------------------------------------------------------------------------------------------------------------------
This is a great little charger, and I do mean little.
The size actually surprised me a bit considering this is a 4 port charger.
I expected this to be a huge block sticking up from my 12v car port, but it actually is a nice small charger.
I have 2 port chargers that are bigger than this is, enough about that, on to the review.
Looking in the package you will find:
The Choetech 4 port Quick Charge 2.0 certified charger
3' USB cable
Instruction manual
The USB cable is one of the best ones I have received with a charger in a while.
It is not thin and flimsy like you usually get.
The charger itself is made of a nice gloss black plastic and looks and feels like it will hold up well to years of abuse in your vehicle.
This charger does support Qualcom Quick Charge 2.0, meaning that it will auto adjust voltages and amperage to best charge you compatible device as quick as possible.
In testing I found this charger to be able to charge my LG G4 and Samsung Galaxy Note 5 in about the same time as my other Quick Charge 2.0 certified wall chargers.
This will also charger non Quick Charge 2.0 certified devices at the maximum rate they will allow.
I tested my LG G3 that is not Quick Charge 2.0 certified and will max out at 2.1a charge rate.
It got 2.0a charge rate from this charger which is great.
There is also a blue LED on this to help you find it easier in the dark.
The LED itself is dim as to not be distracting,
I have attached some pictures showing how small this charger is and me using it to charge multiple devices including 2 phones and a GPS unit.
I have had zero problems with this unit and am glad to have it.
I would recommend this to anyone with a car or truck and either multiple devices they need to use daily or a device that is Qualcom Quick Charge 2.0 certified.
If this review has helped you at all, please click thanks below to let me know.
I received this at a discount in exchange for an honest review, this does not change my opinion of the product in any way.
Hey guys,
I got to use this charger too. Having 4 ports, one with quick charge was really handy. I was able to charge my Nexus 6, Nexus 9 tablet, and an iPhone 5S all from the same charger without having any drop off in charge rate from any of the devices I could measure with Ampere (Nexus 6 & 9). Overall, there isn't much more to say that the other guys above didn't say.
Other thoughts:
It's really small. This thing packs a lot of power for its size.
It is scratch and finger print prone, but I plan on leaving this in the car all the time; so that doesn't really affect me.
The charging light changes color based upon normal charging (Blue) versus quick charging (Green)
NOTE: I was given a discounted product in return for an honest review. All opinions and statements are my own
I grabbed the 2-port charger at 10 bucks a couple of weeks ago at Android Police.
I wonder why there aren't dual QC 2.0 ones out there.

probably grabs too much power and the design to make that might be too complicated without having some power fall off? Personally, my phone is the only QC device i'd worry about and the rest could take the slower charging. But that's my 2 cents.
I have this charger, too, along with a number of other CHOETECH products. Their quality is top notch with affordable pricing!
I have this charger in white so it sticks out surrounded by all the black leather in my car, but that makes it easy to spot and I keep the white charging cable in the quick charge slot so I know which to use when my phone is low. It doesn't seem to charge fast while the phone is in use, but it does charge quickly if you just leave your phone idle and let the charger work its magic.
Even you didn't have a quick charge device, it's handy to have a two port charger. I'm happy with that product.

Ok, I finally got the Choetech T513 charging pad. I was given a 40% off code if I'd do a review. All in all it's a good charging pad. I didn't want a round charging pad because I don't like how the phone hangs off the edges so when I put a back on my S5 to charge it wirelessly I bought first the pad Samsung made marketed for the S5. That little round thing I hated. I then saw the one that was marketed for the S4. This is what I settled for http://www.amazon.com/gp/product/B00F358AVI?psc=1&redirect=true&ref_=oh_aui_detailpage_o03_s00 The biggest problem I had was if you didn't have the phone centered just right the phone would repeatedly keep notifying that it was charging. Wife got upset more then one night. The Choetech is a lifesaver with 3 coils in it so you don't have to center the phone so much. My biggest complaint: it doesn't come with a wall adapter. I was told the adapter for the S7 won't work so I ordered a Quick Charge 2.0 wall charger to charge the pad.
Now for the charging times. I tested With the Choetech in fast charge mode. I tested with the S7 wired charger and I pulled out a 2.1a Samsung charger. I'm a little surprised by the numbers reported but I'm just gonna report what the phone told me. At 34% the S7 wired fast charger would take 59 minutes to fully charge. The 2.1a charger would take 1 hour and 9 minutes. The Choetech charger came in at 1 hour 23 minutes. Not that I was worried about the charging times. I wanted the charging pad for my phone at night. This is when I learned the Galaxy S7 apparently has some kind of a fan in it. When I put the phone on the pad I noticed. With no other noises I could hear a very quiet fan. I thought it was the charger. I tested my wifes phone and same result so I emailed Choetech about it and I quickly got a responce. I wish other companies responded that quickly. She explained Samsung is aware of the fan noise and if I turned off Fast Charging I wouldn't hear it. She then attached a pic of the setting in the S7 battery area that shows where to turn off fast wireless charging. The phone even mentioned I'd hear the fan noise in fast charging mode. All in all I'm quite happy with this charger. Yes it doesn't come with a wall adapter but there are other fast charging pads that do that are much more in price.
Should I use the one by Samsung so as not to degrade the battery?
or it doesn't matter at all?
What brands would you recommend?
It doesn't matter. I use 2 official wireless chargers and one 3rd party pleeson brand.
Not one difference.

I don't know, after the latest system update on verizon my 3rd party wireless charger stopped working. Only charges about 20% then stops.
Shouldn't be. But I'm waiting for the new convertible one to be on sale.
No problem with my choetech stand fast wireless charger.
The S8 supports most wireless chargers, but it's best to make sure the charger you pick was made for at least the S7 if you want to get the wireless fast charge function.
The transmitter for the wireless charger also needs to line up with the right spot on your phone or it might not make a proper connection. I had this issue with my S6 where the spot on the phone was lower than the charger, so I had to put something below the phone to line it up with the charger.
Just saw this fast wireless charger deals on Slickdeals! Hope useful for you: https://slickdeals.net/f/10178316-choetech-qi-wireless-charging-stand-for-galaxy-note-5-s8-s7-s6-edge-and-more-16-ac-fsss?src=SiteSearchV2_SearchBarV2Algo1
I snagged the official 2017 wireless charger for a steal at best buy. I showed them an online add from cdw and they took it!!! Only cause it was the last one in stock and they wanted to slang it quick. Lady at the register was surprised I got the deal.
Bought a Tronsmart Chocolate Bar charger. Works just fine, though I plan to move the charger circuit (replacing the microUSB port with a soldered USB cable or even a QC3.0 power brick) into a 3D printed phone stand.
I have a normal diy wireless charging coil. It heard up more than it charges.
I bought a Black Web wireless charger from Walmart originally as a temporary charger until we got in the Samsung one. Honestly not going to bother. It works well enough, no heat and holds the phone at 100% once charged.
I looked around on Amazon and it seems to be identical to several they sell, just different branding.
I'm content at the moment, was only $20.
My Nexus 6 charger worked only at normal speeds. I like the magnet in it so ordered magnets to attempt to modify the Blackweb charger. They aren't necessarily needed, just something I want to attempt.
