Once you get it done, plug in the phone and it will show that it's charging on AC, which means it's pulling 1 amp.
The 1 amp charger i got from the dollar store already had this in place. I cant say I would have recommended anyone to get one from the dollar store. Ive checked out the components on this one its not too bad.

They currently make something that works with ALL phone models. It is called an inverter. You just plug your stock phone charger into it. It will work fine for your phone but it wouldnt be wise to try use this it watch a 42" plasma tv. Here is one for 6 bucks that plugs in your lighter socket.
Note that most cheap inverters use a modified sine wave to gain efficiencies over 80%. Most phone chargers will work okay you might get a little buzzing. But you will often run into chargers, power supplies etc that will only operate properly on a pure sine wave inverter.
