Setup and Initial Charging
Before first use, it is recommended to fully charge your ROMOSS PSC02 power bank.
- Locate the Micro USB input port on the power bank.

- Connect the other end of the charging cable to a USB power adapter (e.g., wall charger, computer USB port) and plug it into a power source.
- The power indicator light will illuminate to show charging status. Allow the power bank to charge until the indicator shows a full charge (specific indicator behavior, such as solid light or off, may vary).
