Getting ready to do this to my gnex and thinking with all the pucks I have laying around it would be fun and beneficial to attempt this with the N7.
Anyone else have similar thoughts?

I've thought about it -
But, the charger may not have enough juice. The Touchpad uses a different Touchstone charger for that reason, as I understand it. Maybe the smaller N7 would work.
I'll watch any homebrew projects to build a touchstone interface - but I'll probably wait for a charging dock that uses the pogo pins. That would be as convenient as the inductive charger, for me.
I understand what you're saying. Maybe we can rig up two coils for the backplate/battery and use a combo of two pucks lol.

Does anyone know what kind of charger the xoom uses? Is it the micro USB like the droids? I hope so. Thanks.

its not unfortunately. its more like a laptop charger but much much more thin.
No. Unfortunately, it's a proprietary charger with a huge freakin' wall wart.
Watch the XOOM Unboxing vid here to see it.
The video says the USB gives a trickle charge, but that's wrong. The user manual explicitly states NOT to try to charge via USB as it may damage the device. I wonder how many morons will try that and fry their XOOMs.
Confirmed.
keith_4g (Motorola Engineer):
"The USB port is not capable of doing any sort of charging. Any power drawn from a USB charger is leakage current and not necessarily good for the device."
Does anybody know if / where extra chargers can be purchased? I want one for work and home.

Stopping USB charge
How would one prevent a USB connection from attempting to charge the Xoom? Yell at the electrons to stop?
The port just doesn't support charging, just data. The batteries draw too much to charge over USB.

Like most barrel type connectors, it does "click" into place. I'm more worried about the connector breaking off in the receptacle; the male plug is only 1.5mm diameter.
Unfortunately charging through USB is likely to be uncommon with tablets given standard USB's 500 mA limitation. The iPad charges through the USB, but it does not charge when the device is on.
to answer the question about the charger and how it fits. Yes is does slip out of the charging port rather easily especially when using the portfolio case which for me is the biggest design flaw of the xoom. I overcome this by using the docking cradle and sitting the xoom in my lap. Works well for me.
I wonder how true is this? It claims to be a car charger with a micro USB tip.

charger is a disappointment, but not a deal breaker. Another device another cord, just when I thought micro USB was just getting some steam. But on the bright side no orientation issues. I suspect I will get the dock and the charger will not matter.

Its not gonna charge. That charger is designed for a phone. They're just bundling it together like they do for every device lol. Its pretty well documented the Xoom won't even trickle charge over USB.
it is a 12volt power supply. That is why it is so small not to be confused with the 5v mini USB. The Xoom needs 12 volts to charge
I'm sure that someone like iGo will come out with a tip for it. I have already e-mailed them about it. I have two tips for it for different devices that store on the cord so you don't loose them. The will be solutions for most of the issues if we are just a little patient.
Is it possible to do this?

In that case, what product utilizes those?
(So excited just got it today)
Currently there are no docks that makes use of the pogo pins (at least, none that I have heard of, and I have been waiting for one as well). It really is disappointing when manufacturers release great devices, and then either fail or take forever to release accessories for them.
There were some leaked photos of an official dock with pogo pins ages ago, but it hasn't surfaced. Sigh.... Check it out here: http://www.engadget.com/2012/07/31/nexus-7-dock-and-covers-leak/
No HDMI on it either unfortunately, though that was to be expected.

Damn thats stunning. want.
Will something like this ever be possible, like connecting something to the pogo pings?
I think the issue is finding an induction coil capable of pushing the juice needed. Then you could theoretically do a mod with leads going to the 2 pogo pins. I've been following some of the pogo pin threads & apparently when you push the electricity into the charging pins It thinks it is in a dock & tries to route the sound out the other 2 pogo pins, leaving you no sound.
Since the USB charger can barely keep up with battery drain while running, the induction charging will probably only slow down the discharging. It would work if the N7 was turned off. People have had it slowly charge when powered off via the pogo pins.
Yes it can be done. I can't remember where I saw it but someone took two coils from the palm pre and installed into the Nexus 7. It took two coils to maintain 5v to charge the N7. Possibly on Google+ somewhere.

Found it...... http://goo.gl/2gxd5

Would this be possible? I know you can achieve AC charging on the Galaxy Nexus with the palm pre inductive charger but would it be possible with the nexus 7? Does it simply not give out enough power to charge the tablet.
Just noticed HP touchpad has it as well....should have done more research! Maybe this will become an info thread for people willing to attempt it since the back cover is easily removable.
So the touchpad charger (wired) will charge the N7. Does anyone know how much the touchstone puts out? I would like to have this charging mod on my Gnex and my N7 soon with just one touch stone in my house. Just want to make sure the touch stone can put out enough juice for the nexus 7.
Thank you,

Not sure but don't think it would work. I have it on my gnex and the touchstone puts out 1 amp where the N7 stock charger puts out 2 amps. If it did work it would prolly take twice as long to charge but I could be wrong!
Sent from my Nexus 7 using xda app-developers app
HP Touchpad also uses 2 amps charger (in fact won't work with any other) by default and touchstone can charge it even it it's competelly dead. Full charge takes about 4-5h (i usualy charged it during the night), but i never bothered to check how much amps it gives via touchstone. I think it should should work with Nexus 7 as well.
That's what I saw, and also on the HP site it said same Approx. charge time as wired charger. Has anyone torn down the HP touchstone yet anywhere? I'm very interested in this. Wireless charging at home and possibly as a car mount as well.

Any luck with wireless charging mod yet? Would love this feature!!!
Nokia makes a wireless charging adapter, it plugs into a microusb and lets the phone work with their charging plate. I bet you could take that apart and it would be easier to find then touchstone stuff because you can buy it new. I'll see if I can find a link.
I was hoping to start a little project on my N7. I love induction charging and want to set it up on my nexus 7. I was wondering if anyone who has gone through this/know about it/enjoy posting could give me some advice,
Most specifically:
Best dock+backcover combo
Thinnest coil plus chip
Fastest charging
Thanks in advance everybody, can't wait to hear your 2 cents!!

I haven't actually seen anybody fully implement inductive charging yet. However, this guy started doing inductive charging:
https://plus.google.com/u/0/101739011161245720271/posts/fAse7vGmc3q
Well, one easy way of doing it would be to buy a Qi standard inductive charger and a Qi standard inductive charging case (for example, the Palm Pre Touchstone case) and then pull the internals out of the donor case and fit them inside a Nexus 7 case. There's a small amount of soldering required and perhaps some fiddling with the fit, but the components are relatively simple and lay relatively flat. It wouldn't be too hard at all.
Unfortunately, I believe most current Qi charging solutions are relatively low amperage. This would make for a pretty slow charge on the power hungry Nexus 7. Not too bad it you're using it as an overnight charger, but nowhere near as fast as a 2 amp charger. It's possible that you'll find an inductive charger with a higher current output but if you're looking for that it might be easier to build one from scratch,
I did the Touchstone mod on my GNex. It only puts out .56 Amps. Their are kernels with "quick charge" that would let it ramp up to 1 amp but that was it. I am wanting to play with it too, but I'm more thinking of making a dock with POGO pins instead.
I gotta say, they touchstone is great for my GNex. I have a touchstone mounted in my car, so it holds it in place & charges. Occasionally the charge connection gets interrupted (hit a bump, etc...) and it takes 10 seconds to restart. I added additional stronger magnets to my case, but still I don't think the touchstone magnets would do very well holding a tablet instead.
Also, additional magnets screw with your compass...
the touchstone also has a strange angle for watching movies on the tablet.
also i dont know if you can make the induction work with 2amps like the asus charger. (which would be awsome for superfast charging)
If you used the pogo pins for this it would disable the audio if using the correct kernel (see my post in accessories). You would have to modify the kernel to disable it stopping speaker audio out (should be just commenting a few lines though).

The Touchstone is adjustable to whatever angle you want.

neat mod, but seems that it still needs further testing since its so new. qi charging at the end of the video.
very interesting, hope to see a video on how they do it!

I have to believe it is something like the Tylt Vu. It has three coils and is quite tall.
This mod makes me happy as I wait for my N5X to be delivered but that theme just brings back a memory from the only time I've shedded a tear in a video game.
Sent from my SM-G920F
very interesting... Still really risky, you will have to void the warranty to do this and if you don't shield the heat or if the wire touches something wrong it could brick. Just be careful guys. Zsnaps is a safer alternative that makes charging simple. Wish they would ship already

not charger. but a receiver pad.
Why can't someone make a bumper case for the 5X that incorporates a Qi charging coil and plugs into the USB socket? I think there are auxiliary batteries for some phones like that. That would work for me.

Agreed. And (surprising to me) not everyone likes wireless charging. I hope the intersection of the two (and the 5x community) is big enough to warrant market attention.
I asked the poster ,xCubicle....
What's the large light grey patch on the inside of the back cover?
It can be seen in the ifixit teardown images at step 4.
Got the response...
"useless sticker. peeled it off."
I couldn't help but think back to the AMA
specifically the part "...Meanwhile, wireless charging adds z (thickness)..."
So what's the deal here with the blatant capability of qi wireless being designed into the rear case but the spec being deleted...?
It's because they did not want to give qi to the 5x and leave it out of the 6p because it has an aluminum body.

I'm pretty sure you hit the nail on the head here.
It wouldn't have been as bad if they'd just said that, but the bull****ting about thickness as an excuse is not cool.
after further testing with the mod. i am indeed able to charge wirelessly up to 100% from 0%. i measured the wireless charging current and it seems to range from 100-500ma charge rate. a typical charger ranges from 1000-2500ma charge rate.
regardless, its a working mod so far.
i need to refine the wiring to layout to make it a bit more appealing before i offer it as a modding service.
Awesome news. Looking forward to potentially doing this mod myself!

I bought this for my Nexus 7. Yep it is the largest one, you can even buy it from a Verizon store.
Charging time
Can anyone comment on the wireless charging time with the mod compared to the wireless charging time on the older Nexus 5 which had it built in?
In the same boat as many, where the lack of Qi has prevented me from upgrading
What will happen if wireless charging and USB Charging together?
Not even sure what happens now
To answer my own question form my last post. "Even the more expensive Qi modules appear to charge slower than the factory built in modules". Not sure what the reason for would be? Or people do not realize they are buying lower powered (yet more expensive) modules. Most posts I have seen refer to 500mAh modules
