After doing brief testing with my old HTC Evo with a few 2a chargers and modded USB cables, I concluded that the evo would not charge faster than 1a (as there was literally no difference in charge time between a 1A and 2A charger).
I really like these Nokia branded chargers and ended up buying 4 or 5 over the last 2 years. Worked perfectly with my old EVO and its rated at 1.2a @ 5v, plus it has a long cable, comes with a nice velcro cable tie attached (perfect for traveling), and has a 200ma overhead to make me feel warm and fuzzy inside. And only $5 shipped
No idea if the GSIII will charge faster than a full 1a though - if it does I might need to buy some new chargers
Anyone with a 2a charger feel up to doing a comparison test? How long it takes the S3 to charge from 50% to 100% with each respective charger?
