The device doesn't store power (not a battery) it just distributes it through the various ports. The blue light is simply an indication that it is plugged to an outlet and ready to go.
Sorry, there was a problem. Please try again later.This unit only charges other devices when it is plugged into a powered wall outlet. There is no internal battery in this unit. The blue light indicates that it is plugged in to a 115VAC outlet and has power on. It will power/charge other devices when they are connected via their USB cable to this unit and the blue light is on.
Sorry, there was a problem. Please try again later.This isn't a battery but just a usb power strip. It will only charge things when it is plugged into the wall. The blue light is the power light.
