  1. The purpose of a smart power strip is to prevent phantom power drain, which is when electronic appliances suck power from their outlets after they are supposedly turned off. Smart power strips automatically deny power to plugged-in devices that shouldn't be getting it.

    Smart power strips can help you save electricity, but they are not without potential problems. For instance, if the strip uses a USB cable to judge whether your computer is on or off, it might never do its job, because many computers power their USB ports at all times. If your smart power strip monitors voltage to determine when a device is in standby mode, you might have to adjust its level of sensitivity before the strip can tell the difference accurately. Another potential problem is that a motion detector equipped strip could shut down your computer when you have walked out of a room and forgotten to save your work.
