Sorry if this sounds amateur, but I was wondering if I would be able to use my cell phone charger with the Nexus 7 without it causing damage. Or is the reverse true too?
The output on the Nexus 7 charger is : 5V - 2A
The output on the One S charger is: 5V - 1A
The input on the Nexus 7 charger is 100mA higher.
Now technically this means if I use the Cell charger the tablet would take longer to charge right?
But what if I use the tablet charger for my cell phone? Would it damage my phone?
I'm only wondering because I don't want to have too many cables cluttering my workspace.
Thanks in advance.

You're right about the charge time. And yes you can use it on your phone. I have a 2A charger for my g2x that's blazing fast.

It charges super slow on my GNex charger. 10% in an hour
you can use the nexus7 on your phone it will work as a rapid charge, i wouldnt make a habit of it...
Don't quote me on this, but using the 2A charger for your phone should work just fine, as it should have an internal limiter that prevents too much current from being passed through the device, damaging it. I have done that before (with a different charger) with success, so it should be just fine. Also, the N7 *should* charge on the 1A charger, just a LOT slower, and may only charge if you turn it off.
Thanks for all the quick responses guys. I just wanted to make sure I don't do any damage to them.

I got my Nexus 7 now after a long experience with Android devices, mostly phones, and I think N7 is a pain to charge.
Sometimes when I'm using it plugged in charge, it seams like the force is just enought to avoid discharging, no to charge. Anyone with this kind of experience?

Not enough details.
Don't expect it to charge plugged into your PC.
it is normal that charges slow when connected to the PC via USB, in fact most of 10.1 tablets does not charge at all turned on, there is not enough power, if it's connected to the wall charger then may be something wrong.
I'm using the stock wall charger. I'll observe better and than be back here with more data about charging times. Thanks.

Make sure you use the original charger and USB cable that came with it. My experience is that it charges relatively quick and consistent across multiple units.
Does this phone expend more energy to keep up with charging? When mine is charging and I'm using it, it slowly decreases. Is this normal?

Mine too, I find it very strange. However, when I use 2amp car charger, then its all good lol. 1.2amp of stock charger must be not good enough
The phone only draws about 800mA maximum, so a 1.2A charger is more than enough, and a 2A charger will make no difference.

So why is it discharging when its being used and plugged in?

Sounds like there might be something wrong with your charger. Try a different charger if you have one.

Well, its not only me, I've seen bunch of people having the same thing. Lots of defective chargers or perhaps custom roms play role in it?
At times when I leave my phone for charging overnight it stops at a particular percentage and starts discharging. In certain cases with the original charger the phone at times continuously flips between charging and discharging.

I has a similar question about voltages and amperage of chargers and battery degradation posted it here on xda in the nexus 4 forum has to do with this issue of voltages and amps and wireless charging with the official one from google

I had the same problem with mine! Stock charger is GARBAGE! Use something else!
Doesn't anything discharge when no electricity is pumping through the battery? The electricity cuts off when its full. So basically I think the power from the charger bypasses the battery but continues through the phone.
Anybody else seeing that even if your phone is plugged in it will continue discharging if you are using it?

Isn't this always the case? My understanding is that the phone is always powered by the battery and not the plug. If your using the phone and using more power than the charger is supplying then the phone will discharge accordingly. Could be wrong but that's always how I thought it worked.

What's your battery life like? You may have some issues with software maxing out the CPU.
Anyway, the One X battery can run out when using navigation software and on car charger (maybe 0.5A).

What are you using the phone for when it is discharging? Also, are you using stock AC charger or car charger?
Battery life seems fine, i am basically just browsing the web and watching a few yoitube video's, i am usin a 2A car charger.

Can you please try and replicate the same problem with the stock charger? 2A seems fine but just to be sure..
Yeah i will try when i get home from work.

I ran into that when I was using a under rated charger or just plugged into a USB port. Official chargers (or equivalent) didn't have that problem it was slower if I was constantly using it while charging, but it did it.
Playing games, navigate, heavy tasks - looses percentage.
Browsing,messaging, mailing,etc - The battery charges.

I believe this is correct. Whenever I used my Lumia 920 for gps+music on a cheap car charger, it would always discharge faster than it would charge. This is because 1) 12V-car/usb chargers charge at a slower rate than AC chargers and 2) some cheaper car chargers output even lower than normal USB charging rates.
Shopping for a new mobile/car charging solution for my Asus TF300T (gonna use for GPS.. tethered to my HTC One) and my HTC One, i ended up getting this multi-use charger. Initially, i was going to get this high power charger just for usb (which is the first charger on amazon i've seen to output 18 W / 3.6 A), but wanted a more unified solution that I could plug both my One and TF300t into. Because I'll be using the tablet for GPS+music, I can tuck the phone away charging at a tolerable rate. Oh, a direct 12v car charger to HTC One will charge the fastest if that's what you're looking for.
Is anyone else having problems charging their S4? I was using a 5V/1A car charger while on a trip and the phone was actually losing power faster than it was charging. I did have Waze open and was playing music using local files with Google Play, but my S3 was able to handle that fine and still charge in the car.
Additionally, I left it plugged in overnight for 6+ hours using the AC plug that came with the phone and it didn't charge up all the way.
Is there something wrong with my phone?

I had the same problem in my car. I had a cheap car charger that was lower amperage than the standard wall charger. This phone is designed to charge with a 5V 2Amp charger. Your screen draws more power than your s3 so 1amp might be it's burn rate with screen on, GPS, music, etc.
I got a 2amp car charger from thinkgeek that works brilliantly. It was a little pricey. Amazon has one for 6 bucks. I highly recommend buying a coiled micro USB cable so it is more manageable.

Should be as safe as using the stock charger. Even if it was a lot more powerful than the stock charger it would still be fine because the phone itself is what regulates how much power to send the battery.
Recently my wife broke her USB port on her n7, so I decided to just attach some wire to the pogo pins as I know there was a ground and a 5v line. After I installed battery monitor, hers was charging at 1000 to 1300ma. Mine charges at 500-600ma.
Maybe my port is broken too I'm not sure. Can anyone confirm this?

I also charge my nexus from a homemade dock at the 1000-1300 mark compared with my usb port. The usb port is so bad that most of the time I see it discharging while in use!!!
I believe this is a hardware fault as mine used to charge great through usb. at one point my usb socket stopped working altogether, I ran a soldering iron over it and it is at least working again, still slow to charge.
I have also been following a thread about this in the google user forums. One person stated that when they changed the usb board charging rates resumed to normal standards. There is a lot of people in that thread suffering from this. Bad show google.
Have you guys confirmed that the n7 charges faster off the pogo pins?
Sent from my SAMSUNG-SM-N900A using xda app-developers app
It can charge just as fast off USB I know mine does I think the problem seems to be that the ports are easily damaged and it slows the charge rate

I have been following a thread on google forums about people suffering from poor charging rates. I can confirm that many users in that thread, myself included, have found that charging through pogo pins charges normally, whilst the usb charging takes forever and even discharges with screen on!!

is that with the provided 2 amp charger?
It is with a third party charger as my charger broke, but it was the same with the original.

The 5V oem charger output 2000mA. Any charger 2A should fast charge.
Also the pogo pin can charge on 12V 500ma (which is automobile acc. standart)
See more info on Qualcomm FastCharge Standart
There's a chip that identify the power output available. So a charger 1A charger will be identify by the device, therefore it won't fastcharge.
