They claim the device does not consume any power, but then how does the "indicating light" get power?

MEGA POWER SAVER does not consume electricity itself. You can use it continuously 24 hours a day all year round for 10 years without its affecting your electrical costs.

Prior to using the MEGA POWER SAVER, first turn off the indicating light switch. Turn it on only after having plugged it in the outlet. Before unplugging the MEGA POWER SAVER, you need to turn the switch off the indicating light.
