With the Festival season approaching I'm going to need a Battery Pack that can keep this phone charged up easily for a week. For my previous HTC Windows Mobile PDA I used a 24kmah capacity external usb charger, which did the trick. But it doesn't work for the Milestone. From what I've read if a USB charger doesn't output more than 850mah then unless its a computer that can send an authorisation signal then the phone won't charge. And my battery packs output is 5v/700mah. This is an absolute pain. So I'm stuck with a problem and I need a solution. So either I need a new external power pack that can keep this phone going for a week (10kmah+ capacity), and please only recommend something you know works for the Milestone/Droid. Or I need to somehow get the Milestone to charge from a battery pack with an output of less than 850mah.
