I don't know if this has been mentioned yet, but I have been having some problems with an AC charger. I was pleasantly surprised to find that my Droid worked with all my old LG Dare USB cables. The problem is, when connected to one of the AC chargers, the phone begins to act very goofy... It does not correctly register soft-key presses, and swipes are doubled or trippled or don't work at all. Tapping on the screen will result in a tap somewhere else and things open/close on their own. This ONLY happens when connected to this one charger and works perfectly as soon as I disconnect it. I have immediately discontinued use as I don't want to permanently damage my Droid. I urge many of you to use chargers built specifically for the droid.
