i received one of these external battery chargers today. NEW BATTERY WALL AC CHARGER FOR VERIZON HTC DROID ERIS - eBay (item 260609405749 end time Jun-24-10 21:14:30 PDT) i didn't get it from there, i got it from somewhere else (not ebay) and paid way more, but whatever. it works and was still cheap enough for me not to care. anyway, it works!!!! i have my original red 1300Mah battery and two OEM HTC RHOD160 1500Mah batteries. i topped 2 of the 3 off with it and then put one in my Inc. it's been pegged at 100% for over half an hour now so it works and works well. it's really a must have for anybody with 2 or more batteries. this way we don't have to put a dead battery back in just to charge it. we can always have a spare or two fully charged and ready to go. another edit: ok, the battery that i took off of this charger been pegged at 100% for just over an hour and a half now. the phone has just been sitting idle this whole time with Wifi on. i keep waking it up every so often to check the battery level, thats all the use it's gotten, but it does show that the charger charges the battery completely full. so it does fully charge it and it does not drop to 92% within minutes like it can when the phone charges it overnight. yay!
