Energizer just announced that it's trying to get the "tech-wired and wireless younger generation" to switch to rechargeable NiMH AA and AAA batteries. The best way to reach that coveted consumer demographic? Colorful USB chargers, of course! The Energizer Duo can plug into a USB jack or wall outlet, comes in red, yellow or blue, and costs $14, with two AAA batteries included. It's not as sexy as the USBCell, but Energizer does bundle in software, referred to as both "interactive" and "customizable," that will let you watch your batteries charge up. That is, if you've got nothing better to do for about two hours.
