You may not be aware of it, but all the devices you have plugged in around your home draw power so long as they’re connected to it — even if they’re turned off. This effect goes by a few names, such as "phantom draw" or "vampire power," but the effect is the same — your energy bill is higher than it should be.
Smart power strips — such as the Kasa Smart Plug Power Strip — are able to detect when a device is off and cut its power so you only use the electricity you need.
Smart power strips use a variety of methods to control the flow of energy.
Smart surge protectors are almost identical to smart power strips except for one ability — they can protect your device from damaging changes in your power supply. Surge protectors are especially useful for protecting intricate devices such as computers and game consoles.
Surge protectors have two systems for relating how protective they are.
Quality smart power strips vary in the type, count and configuration of their outlets.
Longer cord lengths give you more flexibility as to where you can situate your strip, but if they’re too long they can coil up in an unsightly way. Most strips have cords 1-12 inches long.
Smart power strips usually cost $20-$60, though some of the more basic ones can cost as low as $15. Better power strips typically cost at least $30.

A. Most smart power strips use apps that can be downloaded to any phone or tablet for easy access to controls. However, a handful of apps are only usable on Android- or iOS-running phones. Double-check before buying.
