USB PowerPack
You know us. We can't resist anything USB-powered. We're totally suckers for it, which is why we we're giddy at the prospect of this portable battery pack which we picked up at Compact-Impact that runs on four AA batteries and pumps out a full 5V of juice to all your USB gadgets. We couldn't get it to charge our Treo, but it worked totally fine with our USB vacuum cleaner and our USB laptop light.
