Charging the Power Pack
Begin charging by connecting the included Micro-USB cable to the power pack's Micro-USB port (IN 5V/2A) and to a suitable USB charger. Alternatively, you can charge via the USB-C input (IN 5V/2A) using a USB-C adapter. Charging begins and ends automatically.
Capacity Indicators
- Each status LED corresponds to 25% of the capacity.
- When an LED is permanently illuminated, that capacity level has been reached.
- If three LEDs are illuminated and the fourth is flashing, the power pack is charged to at least 75%.
- If all four status LEDs light up, the full capacity is available.
- Press the button on the power pack to check the current capacity.
- To switch off, press the button twice until the status LEDs go out.
Charging Terminal Devices
Before connecting a device, ensure the total power consumption does not exceed 3000mA. Connect your device using the appropriate cable (Micro-USB or USB-C) to the output ports (OUT 5V/3A). Charging begins automatically. Do not use the USB and USB-C outputs simultaneously, as this significantly reduces the charging current and may overload the power pack.
Care and Maintenance
Clean this product only with a slightly damp, lint-free cloth. Do not use aggressive cleaning agents.
