Smart Power Strip

Smart Power Strip looks like this, it has separate on/off switch for each port. Individual on/off button allows you to plug in various devices and yet be ensured that it is not sucking in power when not in use and switched off.

Don’t be fooled, there are extension cords that looks like the above but are not smart strips. The fact that there is just one switch that controls all the ports does not ensure that power is not being sucked if plugged in.
