CHOETECH QI Wireless Charging Pad and Receiver Pad for Galaxy S4

I got this from Amazon for $22 came yesterday.
I'll need more time to check out how well it works & how long it takes to charge my phone.
Right now I know my phone gets little bit hot with the case on & charging. I'll do more test tomorrow.
The charging pad is compatible with all smartphones that use the prevalent Qi standard.

Wireless Charger Question

I've had a Nexus 7 since they launched last year and I just got the new one on Wednesday. I'd like to get a wireless charger, will any wireless charger work or do I need to look for specific attributes?

As long as it is designed for the Qi standard it should work. I have a LG WCP-300 and I used it to charge the Nexus 7 I bought for a friend. It worked fine, but since it's so small the tablet was poorly balanced on it. That charger is at some Verizon stores for $40 + tax, and Verizon online for the same price with free shipping. The WCP-300 comes with it's own power supply.
I have seen good reviews for the new Samsung wireless charger, it's $50, but it may still be available for half off. You'll need to get a separate power supply, but I think it probably needs to be 1.8 or 2 amp output. It's also larger, so the tablet won't tend to rock or slip off as easily on the LG charger.
You can see threads on both of those qi chargers over on the Nexus 4 accessories threads.

The Panasonic TM-101 is simply fantastic. Toss your tablet anywhere on the pad - and the pad will find it. Will charge multiple devices - sequentially. Nice to have a tablet that is always charged now.

the nexus orb has been great with the 7. my 4 will slide of frequently but I've had no problems with the 7

I bought the Samsung charger with 50% off coupon and so far, it works with original nexus(2 amp) plug, 2013 Nexus(1.35 amp) plug, iphone 4s/5 plug(don't know what amp).
I like that I can lay the Nexus down cross ways to see the charging indicator led come on, also works with i-blason folio case on the Nexus.
So I lay it down to see the led come on, hear the little tone from Nexus telling me that's it's charging, I close the magnetic cover and turns the screen off. I wake up next morning and it was fully charged from ~20%.
So, I'd say the Samsung charger with 50% off coupon is worth it. I think they are backordered right now though.

Any Qi charger should work. The Samsung 50% off deal is nice bout out of stock.
I JUST FOUND THIS, AT&T has the Nokia DT-900 at half off currently. That's $24.50 plus tax.

Another vote for the Orb. Holds it so that you can see the time on it at night if you set Daydream up.

I have read that the Panasonic TM-101 will stop charging once you device reaches 100% then not touch it again to keep up the charge as the phones drains in sleep mode. Something that most other chargers do. That would just bug me.
Even though it cool, I'll be satisfied with the Nokia DT-900 I paid $25 for, and eill keep my device topped off.

Looks like you already made your choice, but I was going to put in another vote for the Panasonic TM101.
I also have a Nokia DT-900, which looks nice and is compact. The only problem is that the Nexus 7 is large compared to the charging plate, and it'll take a bit of practice to perfectly center your tablet onto the charging plate when you can't really see the charging plate under the tablet.
The Panasonic one, as you've probably read by now, automagically positions the charging coil via motors to line it up with your device. The coils light up when they move, so you can visibly see the charging coils as they center behind your Nexus 7. You can hear the motors working, but it's only about as loud as a quiet inkjet printer, so it doesn't really bug me at all.
As far as cases are concerned, you should be fine as long as the case isn't made of metal, and as long as the case isn't too thick. After experimenting a bit with placing a magazine between my N7 and the charging plate, you can get away with about 1/4" of space and still be able to charge.

Also, if you put two devices on the Panasonic, it will charge one and then move over and charge the second. I also read - somewhere - that when one of them drops down to 90%, it will charge again. Unproven by me, since my tablet is always fully charged when I pick it up. Loving it - neatest gadget I have bought in a long time.

I'm not sure what your talking about. I just roughly center my N7 on the Nokia DT-900 and it charges. I'd have to be grossly off for it not to charge. As long as I'm placing my N7 on the charger and not tossing from 2 feek away it works flawlessly. Something must be wrong with either your N7 or your charger.

If that's true, that sounds great. But read or saw a video review that said the opposite. I don't own the Panasonic TM-101, so I don't know which is correct. Maybe someone who has first hand knowledge can chime in.

I got the Choi wireless charger after reading a lot of positive reviews on it, but I'd go for a different brand. I've found that it tends to heat the phone up significantly if I leave it on the charging pad overnight, and it's got a small 'target' for correct phone placement compared to this other one I bought:
http://smile.amazon.com/gp/product/B00E9MUNWU/ref=oh_details_o01_s00_i00?ie=UTF8&psc=1
(Note: that's the U.S. Amazon site.)
This one's got a bigger 'target' area, I haven't noticed much excessive heat (maybe only once that I can recall) but I've only got it at my office vs. using it overnight at home. Overall, it works great for me and I like it better than the Choi, for what it's worth.

I got a LG WCP-300 and a Docooler QI mat....ill post up the pics later but both work just fine...

IMO, I have the Nokia DT100 and the Official Google Nexus Charger and sadly for a quick fast charge.. I like the Nokia one. There is a light status for charging and it's just easier, set it down, it works. Google one gotta line up with the magnets.. BUT your choice on what you pick

I have 2 of your first link. Neither heat my phone up significantly and I have my phone in a case with daydream running. Placement is also not an issue. If you center it and place it the notification sound goes off and it's charging. Great price and it works very well.

[Q] Qi Charger (Stand)

Currently have this wireless charging dock for my Nexus 7: http://www.amazon.com/KiDiGi-Wireless-Charging-Google-Nexus/dp/B00FIG39RC
Works great (once you cover the sticker) and also works with the LG G3 (Verizon, I replaced the NFC sticker with the Qi/NFC from Alibaba).
Would like to get 2 more Qi chargers (both stand style). One to put on my nightstand (for my phone mostly, tablet usually sits in my living room) and another for my desk.
Is there another stand style charge that works well with LG G3 and Nexus 7. Ideally would be slightly more compact than the KiDiGi, as well as better looking and/or not $70.

How quickly does it charge your phone?

it charge at 1.0 a, so is slower than using the usb cable, but for me is not a problem

It is a rubber material and it holds it in place. I bought the same one but it does the power cycle issue where it will charge for 10 seconds, stop charging, and then start charging again. I wonder if only people with the Amazon/Ebay stickers have this issue. I have tried two stickers and 3 different cheap chargers with the same outcome.

Depends on which sort of model you have. G3's sold in India (and I believe Asia as well) have the wireless charging support inbuilt to the default cover as well as the Quick Circle case. US variants don't have it by default as far as I know. I'm not sure about the European models.

how about the tylt vu? http://www.tylt.com/vu/
works well with the G3, but only works in landscape for the nexus 7.

This one, it was basically the cheapest one I could find June 2014. Once the phone is charged you can see the light cycle on and off just maintaining 100%. Works fine for a bunch of devices and I don't notice if it's slow as it has 8 hours to charge when I sleep.
CHOE UPGRADED Qi Wireless Charger Charging Pad https://www.amazon.com/dp/B00DRBFMZM/ref=cm_sw_r_other_awd_WNViwbW7EJTDK

I purchased this plastic replacement back that came with a qi sticker. I used it mainly with this CHOE 3 coil charger, but also tried it on this Yootech one, and this one as well. On all three chargers, the phone got super hot while charging. So much so that at one point my phone even froze up and I had to pull the battery. It may have been the qi sticker that came with the back I bought, but I stopped wireless charging after about a week, because I just didn't like how hot it got.
I'm thinking of picking up another qi sticker, but just can't decide which one is the best.

I'm using the official LG qi charger and the quickcircle cover with qi built in. All working but i find plugging in faster so basically just end up using that instead..

I've found that exact placement on the charger can affect the charging temperature dramatically. I think if the sticker is a little ways off from the center of the qi charger (wherever that is, not sure how that is determined on the 3 coil), it heats up a lot more.

Yeah I tried my best to make sure it was right in the center, but it seems no matter where I placed it it would get hot. Plus what's the benefit of having a 3 coil charger if I have to place it in exactly the right spot? I think there is definitely something wrong with the qi sticker I'm using. If not, many others would be having similar issues. I'm using fairly widely used chargers.

I never felt comfortable using the Qi charging after hearing the noise my phone made when I set it on the charger. I have multiple brands of chargers and all produce the same noise from the phone's speakers (youtube link below). I've tried with cases and without cases on all my chargers.
Here are my qi chargers:
1. Itian Qi Standard Wireless Charger
2. Axiong Qi Wireless 3-Coils Stand Charging Pad Stand Dock Wireless Charger for Qi Phones
3. Tmvel T2 Wireless Charger Charging Mount Cradle Stand for all Qi Phones, with Wide Charging Area for LG G3, Nexus 5, Nexus 4,Nokia Lumia 920, MOTO Dro
4. Tmvel Qi Wireless Car Charger Dock for Qi-Enabled Devices
5. Nillkin Energy Stone For Nokia Lumia 920 1520 Lg Google Nexus 4 5 LG G2 HTC 8x DNA Simple Fashion Wireless Qi Power Charger Charging Pad + Leevin® NF
6. PowerBot® PB1020 Qi Enabled Wireless Charging Pad Station for All Qi Standard Compatible Devices Including Samsung, iPhone, Nokia, Google, Nexus, LG,
7. Ruix Wireless Charger -Qi Enabled Charger - White

So an impressive 50% of folks on the poll at this time have had it crap out.
Wonder if the V10 will have this issue too? I'd consider switching to that, but the G4 is big enough already for me.

1. Works as expected
2. Have it for a week now
3. PowerBot
4. n/a
I'm using the official LG G4 CFR-100 cover btw...

After reading about wireless charging, maybe it's the reason why the feature was removed from phones released in my country. We got a dual sim variant where wireless charging was removed totally.

Wireless charging was removed from dual sims because the circuitry for wireless charging is replaced by that of the second sim.

1. Yes, it worked perfectly.
2. I only use the wireless charger at work and I started noticing issues after the 12th work day. Today is the 13th day and it is no longer working at all. When I power off the device and stick it on the charger, the charging light briefly indicates it's charging and powers the device on and then goes back to the idle state.

The T-Mobile store can put in for a warranty exchange, if you initially bought it with them. But then you get a refurb. It's $20. Alternatively, you could send it in for a factory warranty, but it'll be out for several weeks. And then after you get it back, the wireless charging will break down after a week or two. Ridiculous, right?
I think it's endemic with our H811 model. I wish this could be as big as Antennaegate, forcing LG to admit their poor design+engineering, but there aren't enough users to raise a stir.

I just had an online chat session with LG Support and since they only officially brand their Qi case for Verizon phones they are telling me that the T-Mobile model is not compatible with wireless charging and there's nothing they can do. I got this phone off CL so going to T-Mobile is going to be difficult. I purchased the LG G4 back on release day day but returned it so I was going to use that receipt with LG Support but it looks like that's a dead end.
Another question you should ask in this thread is which model people are using since this is a general G4 forum and not carrier specific. It does look like this happens with Verizon phones too though: http://forum.xda-developers.com/verizon-g4/help/wireless-charging-stopped-t3226231
Thankfully the battery life is good enough on this phone where I can probably live without the wireless charging at work. To be honest It was more of a must have when I had the S6 since there was no way I could make it through the workday without leaving it on the charger.

Wow, really? The function that works (at least initially) because all the hardware is there, on T-Mob, is "not supported?" That sounds like LG support has their heads up their butts, just like the QA department on the wifi charging.
I'll add the question of what version G4 do you have on the questionnaire. Can't edit the poll anymore though I wish I could.

1. Locked up during the night, multiple times a week.
2. Randomly started working perfectly for 3 months. Replaced phone. Worked for about 1.5 months. Now stops charging and locks up during the night again.
3. Nokia puck + Samsung + several chinese ebay units
4. Absolutely no idea why it magically fixed itself and now magically broken.
5. Verizon G4

Using a Yootech sticker with a Yootech puck. Both work well. I originally had a sticker from the Fone company...the colorful one in blue and green, iirc. The wireless charging worked but the NFC was unusable with it. (not that I myself use nfc
