Make sure the batteries' positive and negative directions are right .
Please use chargers which are below 5V/1A to charge it, because larger current deducts the battery and component life.
High-Speed Charging Technology
Intelligent high-speed charging for all your devices and Voltage Boost prevents cable resistance from slowing your charging speeds.
Every time if you use new batteries for this power bank, please charge it first. This is for activating the electric circuit.
No charging time is requested, just charge a second and let it feel the electricity.
If you don't want to charge it, you can also change one or two new batteries, but not all the 3 batteries a time.
