Most new "green" power strips help save electricity by shutting off printers and monitors after you switch off your computer. But the Power Tower takes the concept a step further.
The Tower monitors how many amps your gadgets are drawing from its outlets and acts like a faucet, shutting off power when the load drops sharply — like when your cell phone completes a charge. The Tower then checks back periodically to see if the attached item wants more juice, turning the outlet back on as needed. Result: If you leave your phone plugged in, it'll stay charged without wasting electrons between charges.
The Tower also delivers a standard +5V output via USB ports for charging iPods and other USB-charging cell phones. Its green plugs even rotate to avoid cable kinks or wall-wart collisions. One button reactivates all outlets, even if they've entered "green mode."
