This neat little eco-friendly gadget acts as a power strip to protect your electronics while calculating how much power each device uses.

The handiness of this item is really way up there. You can assess the power usage of everything in your home that gets plugged in. Have a voltage party and invite friends over to compare whose electronics use less energy. OK, maybe I’m going too far there but I can guarantee you that once I get my hands on one of these things I’ll be testing everything in the house.

This eco-friendly power strip goes by the brand name of Kill A Watt and can monitor voltage, line frequency, current leakage, KWH, amperage and more, all displayed on a little LCD screen.
