Capacity indicators:

How to use:

1. Turn the switch to ON and press the BOOT button. The LEDs will turn on and indicate the capacity.
2. Connect the solar panel to DC-002 or the screw terminal with the adapter. If the connection is correct, the Solar Charger indicator turns on. If you reverse the connection, the Solar Warning indicator will turn on. The Solar Done indicator will turn on if the battery is fully charged and turns off the Solar Charge indicator.
3. If you connect the power adapter to the TYPE-C interface, the Quick LED indicates the fast charge mode. The LED is off if your charger doesn’t support a fast charge. The indicators of capacity flashing when charging and turn off when fully charging.
4. The Type-C interface can only be used for discharging, you can connect it to power other USB devices.
5. USB -OUT interface can be used for powering other USB devices.

Notices:

⚫BOOT button: In fast-charging mode with Type-C interface, single-click the BOOT button and exit from fast-charging mode.

⚫If the type-C charger interface and the USB-OUT interface work at the same time, the fast-charging function is invalid.

⚫The fast charge mode can only work if the power adapter supports fast charging.
