There is a button (looks like a power on button) on the top side (connector side), which you press and directly opposite there are tiny, blue LED lights. Four lights on = fully charged. Thus unit holds a charge for a long time.
Sorry, there was a problem. Please try again later.Hi Esme, This power bank has an LED display that shows the remaining battery percentage. When the level drops below 20%, it’s a good time to recharge to ensure you have enough power for your devices. --Energizer PowerPacks Service Team
Sorry, there was a problem. Please try again later.There are four lights on the left top side of the battery. Each light indicates how much battery you have left. All four lights on mean you have 100% - 75%, three lights mean 75% - 50%, and so one for the other two lights.
Sorry, there was a problem. Please try again later.4 LEDs on side show charging and status. Too small and awkward.
