Comment on Why do surge protectors continue to draw power from the wall even if switched off or if nothing's connected to them?

switched off? no. that breaks the circuit, no power, no usage. it’s basically the same as unplugging it from the wall. if nothing is connected to them, many surge protectors have a small indicator light that shows the surge protector is on. that’s about the only power use being used if nothing is plugged in and drawing power.

you might be confusing turning the surge protector off itself, vs the devices it’s connected to- many of which will rather enter a standby mode which still draws some power. (for example, microwave ovens will draw some power continiously so that they’re always ready, even if they’re not always drawing enough power to cook food.)

A surge protector (and the outlet it’s plugged into,) will only draw enough power to meet it’s demand; even if the supplied power is potentially greater- for example, computer power supplies. A PC with a 60w power supply will operate quite happily with a 120w power supply.
