Universal power chargers are certainly convenient--but so far they've been designed to work only with a single higher-voltage device such as a notebook PC. The $60
IGo Everywhere Power 3500 Series doubles the convenience, powering or charging two portable electronic devices simultaneously. Mobile phones, PDAs, MP3 players, and digital cameras can all power up, each one using a separate $10 PowerTip. You need a different tip for each device. The first two are free.universal power chargers are certainly convenient--but so far they've been designed to work only with a single higher-voltage device such as a notebook PC.

One thing we'd change: Clearer labeling might help you avoid plugging a device into the wrong port, and possibly frying it. The two ports--one for AC and one for DC--use the same plugs.

Steroids for Your Headphones

Want to make your girlie-man headphones sound like beefy quadraphonics? Koss Corporation's SSR-1 is a $30 portable surround-sound hack that simulates 3D sound for any headphones. Powered by two AAA batteries (good for 30 hours of listening), it includes an integrated amplifier and volume control and gives stereo a more zestful, theaterlike sound.

One thing we'd change: A protective carrying case for the SSR-1 would be a very helpful extra.
