The Green Lion Solar Force 20,000mAh Power Bank (Model GL-PX82) is a high-capacity portable charger featuring integrated cables, solar charging capabilities, and a built-in 4-mode LED flashlight. This guide covers essential operation steps, including how to charge the power bank, use the low-current mode for small devices, and operate the flashlight.
Product Overview
The device features multiple output options including USB-C, two USB-A ports, and integrated Lightning, Type-C, and Micro-USB cables. It supports PD 20W fast charging and QC3.0 technology. The integrated solar panel is designed for emergency or outdoor use under natural sunlight.


Setup and Operation
Checking Battery Level: Perform a single short press on the power button to view the remaining capacity via the 4 LED indicators. 0% (all off), 1-25% (1 light), 25-50% (2 lights), 50-75% (3 lights), 75-100% (4 lights).

LED Flashlight: Press and hold the power button for 4 seconds to activate. Cycle through the 4 modes (High, Low, SOS, Strobe) as needed. Press and hold again to turn off.
Low-Current Mode: Designed for devices like smartwatches or Bluetooth earphones. Double-click the power button to enter this mode (indicated by cycling flashing lights). Double-click again to exit.
Charging the Power Bank
Via Power Adapter: Use a certified cable connected to the power bank's input port and a wall adapter. LED indicators will flash during charging and remain solid when fully charged.
Via Solar Power: Place the solar panel under natural sunlight. The solar charging indicator will light up when solar power is active. Note that solar charging speed is dependent on weather and sunlight intensity; optimal output is approximately 300mA/h at 25°C.
Safety and Maintenance
If you notice any swelling or leakage, stop using the device immediately. Do not dispose of the power bank in unsorted household waste; follow local recycling regulations. Keep the device away from extreme high temperatures.
