Is it safe to use the Nexus7 charger (2A output) on the S3?

Yes.

Its possible but not something i would risk as it may actually damage the battery or even the charging circuit which charges the battery in your GSIII if it can't withstand the higher rate of charging.

Simple Guidelines When Using a Charger:

-Use the correct charger for battery chemistry. Most chargers serve one chemistry only.

-The battery voltage must agree with the charger. Do not charge if different.

-Within reasons, the Ah rating of a battery can be higher or lower than specified. A larger battery will take longer to charge than a smaller one and vice versa.

-The higher the amperage of the charger, the shorter the charge time will be. There are limitations as to how fast a battery can be charged.

no problems. I used my hp Touchpad 5v/2a charger and it works fine. Won't charge any faster than the stock charger though, due to the stock kernel. It would be theoretically possible to charge faster with the right kernel.

A higher amp charger will not PUSH more amperage into the phone. A high amperage charger will have more amperage available if PULLED. U could use a 5 amp charger if u wanted as long as its only 5 volts. The phones kernel has charging software that only allows the phone to charge at a defined rate.

It is perfectly safe to use a charger with higher amperage than stock.

oh, not because I want to charge faster, just don't want to carry 2+ charger around with me. Thanks for all the respond, much appreciated.
