If there USB light around the USB port doesn't light up, please check the following:
1. Make sure you are using our supplied USB-C cable, or a cable for phones built for high-power charging. Not all USB-C cables support high currents.
2. Make sure you are plugging into a wall adaptor capable of at least 1A of charge. Note that laptop/computer USB ports only support 0.5A, and adaptors for headsets and other small devices don't support enough current to charge the case.
The LED light around the USB-C charging port on the case will turn orange while charging, and green when the case is fully charged.
