"Tired of running out of juice when you're on the run? The Tekkeon TekCharge MP1800 is a rechargeable portable battery pack that supplies power to phones, MP3 players, Bluetooth headsets, and other mobile devices. The charger comes with seven adapter tips for use with most kinds of mobile phones, but you can also use the USB cable that came with your iPod, Zune, or other device. In other words, it's almost universally compatible, provided that your gizmo can be charged via USB."
I think I'm going to order one of these as is should cover my iPod, Zune, and phone. The normal price is $44.95, but right now Amazon has them for $28.99 $39.27 (they hiked the price!). [Affiliate] Unfortunately there is a couple of week backlog on their supply, so it will be a bit before I can share my thoughts. Anyone out there already have one of these?
