found this portable battery charger on Amazon for 10 bucks, got mine yesterday and actually used it last night, charged my Droid razr from 10-60% and my friends HTC Evo 4g from 5-50% on the same charge, it's t mobile branded but works with any phone utilizing USB charging and the iPhone, the battery is 1700mAh as well, thought I would share this great, low cost product.

Hard to go wrong for $10 but I wonder how much of a charge you would get if your droid was down to 10% and you tried to get it back to 100%.
