What makes power strips the best on the block differs from person to person. Maybe you get taken in by the colors or you like when plugs are on multiple sides and can rotate. When it comes to energy saving tips, however, it’s important to pay attention to functionalities. For that, you may need to check the specs.
One feature you might enjoy is a power strip rated as masterless for devices that don’t need to remain on all the time. These power strips recognize when everything plugged in is turned off and turns off as well.
Another option is to get a power strip with a master switch. When leaving the house or going to bed, you can simply flip one switch. This kills the power to everything that’s plugged in, eliminating ongoing power drainage.
