100% on the voltage! That is the important one. .7a shouldnt be recognized as a real ac charger resulting in the phone thinking it is USB 500ma charging mode which is the same as pc, slow. If the device thinks the .7a charger is ac charging mode, the battery probably will never charge to 100%. In fact if you were at 100%, and the phone was in ac charging mode with a .7a charger, it would drain your battery! More than 1a, the phone will only draw what it is capable of. Some aftermarket chargers will still charge in USB 500ma mode because the phone won't recognize them as ac charging 1a mode. I had an old HTC charger once that did funny things to my inspire, it would open navigation every time it was plugged in(thought it was a car dock I guess). Use real OEM chargers if possible. They will charge the fastest, and you won't have issues. The real HTC chargers at 1a are much faster than the aftermarket chargers I have tried. I have a good Kensington 1a car and wall charger, and the HTC blows them away as far as speed!
