(From the manufacturer)
PRESS THE POWER BUTTON FOR 2 SECONDS TO TURN ON/OFF THE AC OUTLET. REMEMBER TO TURN OFF THE AC OUTLET AFTER USING OR THE BATTERY WILL DRAIN OUT.
It is NORMAL to hear some slight NOISE coming from the battery when using the AC [plug]. BECAUSE THE INSIDE FAN IS WORKING TO COOL DOWN THE BATTERY.
This product does NOT support Charging pass-through function.
