This is the type of thing that makes you look like a bonafide geek. The Wrist Band Portable Battery really exists, and is designed to look like a watch or bracelet so you can recharge your portable gadgets fashionably. It comes with seven types of power connectors that attach to a coiled cable that plugs into the charger. It apparently charges your other gadgets too, including your music player, and handheld gaming console so you won't feel like a total dork for nothing. The wearable rechargeable battery pack provides up to 3 hours of talk time or 8 hours of MP3 use, and will only set you back $25 if you're lucky enough to get one. Product Page
