CUSTOMER REVIEW



I attached this to a Kill-A-Watt power meter. Then I plugged in zero to four devices. It scales up power draw as you add each device. Furthermore, when a device is finished charging, it drops the draw again. Draws zero watts (I assume rounded down from something between 0.0 and 0.049 watts) when there are no devices attached or all devices are charged. This enables me to leave it plugged in 24/7 - significantly better than all the plugging and unplugging I used to do.
