I can't seem to find the answer I'm looking for anywhere so here it goes..
I am mounting a Nexus 7 in my car with a bluetooth head unit to get sound through my speakers. If I make a dock containing pogo pins to charge the device, can I run those pins to my cigarette lighter so the N7 charges will the car is on? I have a 12v to 5v 3A converter on the way if needed. I really don't want to fry my battery and have to start over.
Could this idea cause any problems? Thanks in advance.
I don't think the pogo pins will charge the device fast enough to keep up with the usage. So if you travel it will slowly deplete. It is a slow charge. People do this though.
You should also look into installing a wireless charger under your battery door so it charges through induction like the Nexus 4. There are videos that walk you through this. Usually they connect the wireless disc up to the pogo pins or to the battery contacts directly.
The N7 will shut off charging once the battery is full, so youd want the power always on through to the cable.
Food for thought. There are numerous threads here in the forums that show people doing this and their findings. I would do the induction charge though for ease of removal and hassle. You can pick up a touchstone charger and disc for probably $20 on eBay. There are specific models to look for and the details would have to be researched.
My buddy did his N7 and he said it was super easy. His only beef was the N7 was too heavy for the included magnets to really keep a secure connection and some people also purchased stronger magnets for under the battery door to fix this. They turned out so strong that the N7 would actually hang simply by the magnets so it kind of "snaps" in place.

I have (and love) this feature on my Nexus 7 and a Galaxy S4. Very convenient and works great (yes, even with a case on.)
That HTC didn't include it on the Nexus 9 is a bummer.
Looks like one "solution" could be to add an aftermarket QI receiver: http://www.amazon.com/s/ref=nb_sb_n...ireless Charging Receiver film for micro-USB
I wonder how well that would work?

If using a Qi receiver, theres only 2 ways it can work 1) plug the Qi receiver and insert it between the battery and back cover, thereby voiding warranty OR 2) plug in the receiver and sandwich it between between the device and a case.
Neither solutions will be pretty.
But will a QI reciever stop charging when battery is full? Is this controlled by QI reciever or tablet?
I think they took it out due to it size...... I have not see something that size with wireless charging

My old HP Touchpad running WebOS and now also KitKat 4.4 has had wireless charging from the start.

It should, I'm pretty sure the QI receivers tell the transmitter how much power to send, and I'm sure there is a charging power management IC that stops charging intelligently or the battery would surely cause problems.
Has any one any experience with wireless charging on the Yotaphone 2? It supports the Qi standard but I've not ever had any device that can be charged wireless so I don't know what to expect.
There are some cheap chargers on ebay so I may get one to experiment with but wonder what others are using, how long a charge takes? is there a tiny sweet spot to get it to work? does it get hot? Any compatability issues?
Thanks

Hi there,
Yeah actually I got one for my YotaPhone 2, it's ADATA Elite CE700.
First I have to say I was very disappointed because apparently you can only wireless charging the YotaPhone2 with the main screen facing up! Also you should know that the spot where Qi located is a bit small (3cm in height in the middle of the EPD Screen), but that also depends on the type of wireless charger you would use. Something like Tylt Vu would Support more area thus its more hassle free.
It's also good to know that with wireless charging you won't get Quick Charging anymore. Because In order to do that you must use the MicroUSB port. But again how long a single charge takes depends the type of the Wireless Charger and the amount of output current it has which most of them are 1~1.5A.
For your last concern, any Qi Wireless Charger will do but try to get one of the Tylt Vu. It has the best reviews. And the phone won't get hot during wireless charging if you must know.
And something which I'm not sure whether its my wireless charger or it's general, is when the battery is 100% the charging won't stop, unlike the normal charging with dedicated adapter which cut the current when the charging is complete.

Hi, thanks for your detailed reply, I've now ordered two different generic chargers off amazon to experiment with, they are coming from China I think but were less than a tenner, I'll report back on these after ive used them for a bit.
It seems less than ideal for me to have to charge with the EPD facing down but I guess this is an engineering limitation. I'm sure there would be advantages and disadvantages of each side facing up during wireless charging.
I recently bought the Nokia DT903 wireless charging plate.
It works effortlessly with the Nexus 5. I can pick it up and place it back for charging with no connection worries.
With the Yotaphone 2 it does work, but it has to be in EXACTLY the right spot.... I'm talking millimetre precision here.... it becomes really frustrating to use and spoils one of the key benefits of wireless charging.
That's what is worrying me about Qi charging, I like the idea of wireless charging for the convenience, I work shifts and fiddling with the usb cable when I get in can disturb my partner, just being able to lay it on my night stand would be great, but sometimes I check the time on my phone in the middle of the night, or get up for the loo and nudge the charging cable and move the phone and if its really fussy about how it sits on the charger then I could end up with the phone not being charged overnight.
The ADATA Elite CE700 mentioned by Parisabs4 above looks like a good solution as it is adjustable and with the phone sitting on the cradle it is hopefully easier to hit the sweet spot.
QI charging experience
Okay so I've now tried 3 different Qi wireless charging plates and I have found that all of them exhibit the same problems whilst attempting to charge my Yotaphone 2
In the picture there are 2 single coil chargers and one triple coil charger (the one that is not flat) they are budget models, costing between £4 and £7 on Amazon.
I can get the Yotaphone to begin charging correctly on all three chargers, the phone says it is charging and the qi devices LED blinks to confirm charging. After 10 - 15 seconds the Yotaphone & chargers will stop charging, the indicators on the phone and charges indicate that charging has stopped. After a couple of seconds charging will recommence for about 15 seconds and the stop again, this cycle repeats for a few times then charging stops all together. Lifting the Yotaphone off and then returning to the charger will recommence charging.
My conclusions are that
My device has a faulty wireless charging receiver. (This is unlikely as im on my second device with the same symptoms after an RMA for a previous fault)
The charging software in the Yotaphone is buggy.
The Yotaphone is not fully compatible with the QI standard.
The Qi chargers I am using are not powerful enough for the Yotaphone. (Unlikely as I've now tried 3 different chargers but they were cheap!)
Has anyone else experienced this problem or is using a charger that is proving reliable?
I'm tempted to try the official wireless charging block as it ought to be compatible with the Yotaphone but its £40 wasted if not (although it can charge via a usb port too)
WHY IS NOTHONG EVER EASY IN THE TECH WORLD!!!!
The "old" Samsung S-Charger does not work either.
I got the following white list from the Yota support:

Thanks for that info, I've ordered a Nokia DT-601 from the whitelist, fingers crossed!
As a footnote I have found my tablet charger (a 2.1amp samsung) works with one of my qi charging plates to charge the yotaphone but any other 2.1amp charger exhibits the same problems as the regular 1 amp chargers I've been trying to power the qi plates. Also I've discovered the Yotaphone will not charge from the usb socket in my car but any other device I connect to the socket charges fine, this is one flakey device!

Thanks matts2 for sharing the list
I bought a Nokia-601 (£12.99 of Amazon) an it works perfectly, I've just charged from 35% to 100% with no issues. It even comes with its own 1.5amp mains usb charger
I'm happy happy happy now

I bought a cheap nameless one, have yet to receive it, I hope it will work in combination with a powerful adapter. Anyone got these cheap (5 USD) chargers working with their phone?
Another good QI charger for YP2 is/are the ones that IKEA sells. They have several models, but all seem based on the same platform powered by a 19V DC adapter.
I couldn't get any cheap QI chargers to work reliably with my YP2, but the IKEA chargers work great. They have some margin in positioning the phone on it, and prices start at around $30/EUR 25, so not to bad. I cannibalized the electronics from a JYSSEN to transplant them into a custom 3D printed charger case.
Does anyone have any experience using this Samsung 2A charger with the Yotaphone 2?
https://www.amazon.com/Samsung-EP-PG920IBUGUS-Wireless-Charging-Charger/dp/B00UCZGS6S/
UPDATE: Never mind, I ended up buying the Nokia DT-900 since it's on the official list of supported chargers.
I bought my first wireless charger , a cheapo one from China just to see how they are. Cheap as in 4 USD. It does work but exhibits behaviour like described above. All night only charges it a little and the on light is not on much. I thought it was a problem with a cheap charger, but maybe not, it sounds like Yotaphone firmware. I don't have any problem finding the sweet spot.
I was reading about new LG fast charger that is coming out soon, first ever fast 15w wireless charger. But of course it will be expensive .
http://m.androidcentral.com/lg-announces-new-super-fast-wireless-charger-get-you-cables-good
I bought an 3-coil-qi-charger-stand from China (eBay article 381639407985) about 10€. It works perfekt.
Cheap Single coil charger work also, but only if you place the Yotaphone at the exactly right position ( only 2mm tolerance). As the coil inside the 2,80€ single-chip-computers charger from China is often not places correctly inside the housing, you first have to correct that.
So tripple-coil is to be prefered.
One nice thing: Charging via QI and USB-OTG works fine at the same time on Yotaphone. You can put the Yotaphone 90 degree rotated on the 3-coil-charger-stand and watching Videos from a USB-Stick.
I even think about building an own small OTG-Adapter, using a extreme small micro-usb-connector (like used in universal QI reciver-plates), a very small USB-Micro-SD-Reader, some wire and epoxy. The SD-Reader will be placed on the lower frame of the ePaper. I use a bumper and would cut the neccassary space out of it. So I could build an nearly invissible (with bumper) SD-Card-slot. 64GB extra space is nice...
I'm using a Nokia DT-910 that I originally bought for my Nexus 5 a few years back.. works just fine with the YotaPhone 2..
No need to be careful with positioning or anything like that.. just put the phone on it and that's it.
The benefit of a charger like this is that you can actually see the screen while charging instead of it being flat on the table like some other models.

Never thought about it but they do seem quite common https://www.youtube.com/results?search_query=qi+wireless+powerbank
Or you can easily make one yourself by taping a wireless charger to a powerbank
In that case there is a wire, between PB and Wireless charger. �� so NOT wireLESS, lol
Can I use a QI Wireless power bank to charge the Yotaphone in my pocket?
Sometimes my phone runs out of juice. Is it possible to buy a power bank with wireless charging capabilities and use it to tirelessly charge my phone, by placing the power bank in my pocket next to my phone?
