Monstrous Battery Pack Promises 20 Hours of Video Playback for iPhones

USB Fever's 3000 mAh add-on promises 8.5 hours of talk time or 20 hours of delicious video playback.

According to the manufacturer "it's not bulky either as it just extends a little at the bottom"—yeah right, and Steve Ballmer is just a little intense. The Super Charger is positively ginormous, but if you have a sherpa (or intern) to help you schlep it around, the battery pack can be picked up for $60. It won't void any warranties, but it should.
