QI Charging Pad for Multiple Devices

So I have a Nexus 4 and Got the new Nexus 7 2013 edition. I'm now in the market for a charging pad that can do both of the devices at once. Any suggestions?

Just got the n7 myself too. Its on its way. Wireless charging might not be a deal breaker, but my mattress is tall and I hate plugging in and unplugging every time I want to use it from bed. Hopefully there is a good dual qi charger for these 2 devices.

I found the Energizer® Dual Inductive Charger is there anything similar?

This is the only one that I've seen that does 2 at once. I have it and it charges mine and girl friend's n4 great at the same time. I don't have a new nexus 7 to try though.

Using Nexus 7 (2012) Charger?

Would it be detrimental to use the stock charger that came with the 2012 Nexus 7 to charge the device? I asumme they're different voltages or amps, but not sure if the Nexus 7 charger can adapt? Cheers!

im charging mine on my N7 charger, i also charged my N4 on it, no problems

I'm using different chargers (Samsung, HTC, Motorola) and all of them are working fine with my Nexus 5 as well as with the I9100 my wife is using.

One word of precaution.
I used a car charger that outputs 2.1A with my galaxy S4 while driving and using the navigation for about 8-10 hours.
Eventually the phone's mobile and GPS chips died.
The phone cannot lock any signal whatsoever.
Before I'd been using the phone for 1 months without a single problem.

Considering you used it to 10 hours, the device probably got super hot which is compounded by the device being charged at the sametime so hardware failure isn't a surprise.

they are both Lithium Poly chargers. you'll be fine

you can always use any charger that fits! All micro-usb chargers are 5V so there are never any issues for the phone. Type of batteries etc does not matter. It is only the voltage that matters. The max current (Ampere) of the charger affects charging time as long as the ampere is lower than the max current the phone can handle.
The "charger" only provides a stable voltage with over-current protection, nothing else, all battery related intelligence is placed in the phone.

Wireless charging question

Was wondering whether there are things to watch out for when considering wireless charging. The charger supplied with the phone is a normal one as far as i know. Are there any drawbacks when using any wireless charger? Is the hp touchpad touchstone compatible? Any info will be much appreciated

they generally charge slower. maybe twice as long(or a little less than twice as long)

The touchstone probably won't work - it's not Qi compatible.
If you're using the Nexus 4 wireless charger, the good news is that the 5 doesn't generally slide off.

Nexus 5 draining in the car

I bought a dual usb car charger from eBay that is supposed to output 5v 2A on one socket and 5v 1a on the other, but while leaving it like that in my car it still drains the nexus 5. Tried to only have the nexus 5 connected to the 2A socket aswell but still discharges over time.
What can be the issue here?

Probably either a bad USB cable(s) or chargers that are not putting out the amperage as advertised. There are a couple posts you can find in the accessories forum that show the effect of low vs high quality USB cables. Summary: there is a big difference.
I've personally been on the hunt for good cables and charges for a while and recently bought a car charger that charges while I listen to music and use Waze while driving. Very happy now, we'll I am, my wallet isn't.
Try current widget while hooked up to the charger. You can test how many amps you are drawing.

It may be like the post above, drawing USB charge. I think I read somewhere there is a mod to enable fast charge.

Tried some different cables in the truck now at lunch, the ones I used before got minus even while charging, these were cheap flat cables from China, tested with an Asus one i had laying around and that gave me ~700+ mah. So from -70mah to +700mah is quite the difference just by switching cables.

Nexus wireless charger rate?

Hello everyone.
Does anyone by chance know the charging rate (in MV) for the official wireless charger?
I just want to make sure mine is charging correctly.
Logging using battery widget monitor it fluctuates between 580-700 MV/minute. Does this sound normal?
Thank you!!!
