Portable Power Packs: Don't Leave Home Without One
Smart phones, tablet PCs, digital cameras, MP3 players, portable game players, ebook readers - all powered by batteries that drain, usually at the most inappropriate time. I pack my portables into a Powerbag, but here are some other new portable power options you shouldn't leave home without.
Portable Power Packs: Spyder i4 iPhone Battery Case/Dock
Here's the world's first and only battery case ($90) equipped with its own docking station - no more trailing USB cables, just drop your i4-encased iPhone into the dock to recharge both. Inside i4's the polycarbonate shell is a 2000 mAh battery (an iPhone is powered by a 1440 mAh cell). It'll be available in July from Spyder Digital Research.
