Does a surge protector or a simple power strip increase or decrease the ‘vampire’ effect?
Lawn Gnome asked:
Or which one handles the ‘vampire’ effect better, the surge protector or the power switch?

“vampire effect” is what?
After a bit of searching, I found this: (wikipedia).
Standby power, also called vampire power, vampire draw, phantom load, or leaking electricity, refers to the electric power consumed by electronic appliances while they are switched off or in a standby mode. A very common “electricity vampire” is a power adapter which has no power-off switch. Some such devices offer remote controls and digital clock features to the user, while other devices, such as power adapters for laptop computers and other electronic devices, consume power without offering any features.
A simple power strip will eliminate the standby power of anything plugged into it, as will a power strip with built in surge protector, as long as it has a switch to turn off all the outlets.
However, a surge protector, depending on it’s design, may use some standby power on it’s own.

if power strip or surge protector has a capacitor circuit it will bit increase, cause capacitor stores energy & release slowly.
