“What is the button for on the charger. Nothing seems to change when I push it.”

• I believe the button shows you how much power the charger has in it. 4 solid blue lites means it is fully charged. Just plug it in to fully charge the portable charger. It only fits one way in the small plug on the end of the portable charging device next to the button. There is blue blinking lites when it is charging. Then 4 blue solid lites when it is fully charged.

• It is to turn on the battery. It wasn't working for me until I pushed the button.
