I ordered and received the PowerQI from China. Cheaper then Google's and I could order it. It came already. Works like a charm.

Does anyone know if any of these mats work when the official bumper is fitted to the phone?

I'd guess the maxell does, or works through my tpu case which has rubber all down the back of the phone so with nothing in the way I'd think the bumper would work fine

Hi,

I've ended up getting two QI Chargers this week. I only ordered the car version, but actually got the car version, and the desktop version. Dunno why, maybe I ordered wrong, but whatever...
The charger is here:
Car version:
http://owlpad.net/carpad-for-nexus-4/
Desktop version:
http://owlpad.net/ow...r-nexus-4-n-qi/

Initial impressions are good. Both the car charger and the desktop charger did indeed charge the phone.

The car charger struggled on the *very short* journey I did yesterday (6 minutes!), phone was 96% charged, and the car charger said it was fully charged in about a minute, the phone stayed at 96% however, so who knows. But that's good enough for satnavving, if it holds the charge long enough. I shall be testing it this afternoon when I go for a much longer drive.

I've mounted the car charger onto a 17mm mount, in turn mounted to brodit mount in the car. It's all a little bit more bulky than I would like, but looks nice and keeps things away from the screen, which is what I want.

Oddly, the car charger comes with a raiser, to move the phone off the QI coil a little bit. Moon (the man who made this), says it's to prevent heat build up with charging the phone and using satnav at the same time. I shall try it both with and without the mount and see how I get on. Heat build up and the phone/unit ceasing to charge when it's getting too hot have been a major problem during the development of this product. The car environment only makes it worse, with sunlight hitting the device and high temperatures (or no air-conditioning) causing issues (I did experience this more than once with my old Orange San Diego with regular wired charging).

The desktop charger worked fine. Woke up this morning to 100% charge, but oddly the phone said it had only been off the charger for 26 minutes when I took it off the QI charger, so maybe it had charged, discharged a bit and then charged again? I don't know. I use a app in the background to help me sleep, so this might have something do with it. I've heard awful things about this charger crapping out at 60-80%, so I guess time will tell on that one, but initial impressions are good. So be honest, even if it charges in chunks and stop/starts overnight, I think I'll probably be okay with that.

I've only used both items once so far. Will report back later if anyone is interested in hearing more?

The car charger problem may be that at 96% it doesn't initiate the charging process, unlike the wired chargers wireless ones only kick in of you drop below a set percentage, I think it's either 90 or 95%

Hi Guys, I´ve ordered one of this very attractive QI chargers on ebay : http://url9.de/yZo . There is also an XDA thread about it (http://url9.de/yZV), and the overall performance and usability seems very good. Maybe it´s a good alternative for people like me who are unable to get an official Orb. I will report back when mine arrives from China if anyone is interested.

Please do! I'm very interested in this charger. It's a shame that it's not £10 or £15 cheaper but I guess while the official one is still so hard to get hold of, the 3rd party manufacturers can pretty much dictate their price. I'm hoping that prices will start tumbling as more chargers come to market and more handsets support QI - I'd like one for my desk at work, one for my bedside table, and one for the coffee table - but at £40 each I'll probably stick with my $2 retractable usb cable!

Ive just ordered one of these

http://www.ebay.co.u...=item257e280854

Will let you know how it goes but seems good value and it's a name that's been on xda. I ordered through his website but a friend apparently works with this guy so if it sucks she will be unleashed on him

Well my cheap charger arrived yesterday, it works fine with the nexus, nothing special but for the price I paid I'm happy. It's smaller than the maxell one but that means it won't clutter up my desk as much

That's quick delivery! Does it have a blindingly bright light while charging? If not I'm gonna get one

The guys in harrow so it didn't have far too come. I've only used it in the day time do didn't notice the brightness but the light on it is always on, it just changes colour when charging.

It comes with a micro USB lead and 1.5A USB plug, tried it yesterday and it manages to charge from a PC USB port but I presume that will take longer. Left it at work though so can try some more things out on Monday when I can get to it again

There was an unbranded one mentioned on xda that was cheap & good but had a really bright blue light so it couldn't really be used on your bedside table.

i'm sure with a bit of DIY this could be very easily remedied..... :)

if you are confident with your mitts just take it apart and disconnect the led.

if not, get some tape or paint the led cover with white (blackout) paint.

Absolutely - that's what people over there have reported doing (disconnecting the LED)
Just would be nice to have something work right without having to open it up first - also a (dim) light to say the device is located correctly over the coils and is charging would be handy (I've read it can be easy to assume your phone's in the sweet spot and then wake up to find it wasn't and didn't charge). I spose though, the N4's LED indicator should tell you if it is charging or not
Maybe painting over the light is the answer - would act to dim it a bit.

It makes a noise when you successfully put it on a wireless charger. Then the notification light on the n4 will tell you if it slips off

Problem solved :)

I can't say the light on the cheap one seems that bright but I've only used it in a well lot environment. I couldn't see the light through a napkin. It has a weird problem that if u leave it till it's fully charged I can't charge again and need to unplug and re connect the pad. Not a deal breaker for me as it does this when I turn my PC off at night anyway, but again it could be a deal breaker for most

That's one of the funnyossities about all these devices from what I've read - they all charge to 100 percent then stop. There's no facility for top up / trickle charge, which is a bit of a nuisance if you're leaving it on for an 8 hour overnight charge (for the final 5 hours it will be discharging). Wonder if Tasker might be able to help, say by turning off wireless charging when it reaches 95 percent then back on half an hour before your alarm is due to go off?

This one is worse than that, I have to physically disconnect the charging pad to get it to work again so tasker won't help me. As I said it's fine for my use as turning the computer off reboots the pad daily anyway but it would be a problem for overnight cycles
