Power by Power Bank
The projector can also be powered by a power bank.
15V/3A
1. Connect one end of the USB Type C cable to the USB C port of the projector.
2. Connect the other end of the USB Type C cable to the power bank.
NOTE:
• The power bank should be 45W (15V/3A) at least, and support Power
Delivery (PD) protocol output. Additionally, at 15V/3A the projector can be
powered on and charge simultaneously.
• Due to the IC protection mechanism, the USB-C charging function may stop
briefly then continue later on.
Using the Battery
The battery level icon will show at the top right of the Home Screen. As the
