The iGo Green Surge Protector Tower  is one of the “greenest” charging stations we have ever seen. It is so smart it automatically cuts off power to devices when they’re in standby mode but has four always-on plugs for constant energy munchers like your DVR. It 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 oversized AC brick collisions. One button reactivates all outlets, even if they’ve entered “green mode.” Check out this and many other green charging devices at www.igo.com ($80)
