Just got my first Android - could definitely use a backup power supply. I need an extra for when I go to hospital for heart problems at, usually, end of day!
I'm the proud owner of an OG Droid with a pooped out screen and a smashed Droid X. Buying a used Droid Eris and a parts phone to fix the original Droid that's broken. I would love to have an accessory like this!
