5. Charging the Power Bank

Your Kepswin PS25K Solar Power Bank can be charged via two methods: USB-C or solar energy.

5.1. USB-C Charging (Recommended)

For the fastest and most efficient charging, use the provided USB Type-C cable and a 5V/3A USB adapter (not included).

1. Connect the USB Type-C cable to the power bank's Type-C input/output port.
2. Connect the other end of the cable to a USB wall adapter or computer USB port.
3. The blue LED indicators will illuminate to show the charging progress. A blue light indicates USB charging.
4. All four blue LEDs will be solid when the power bank is fully charged.

5.2. Solar Charging

The solar panel provides an emergency charging option. Due to its size and the power bank's large capacity, solar charging is significantly slower than USB charging and is intended for emergency use or to maintain charge, not for primary full recharging.

1. Place the solar panel of the power bank in direct sunlight.
2. A green LED light will illuminate, indicating that solar charging is active.
3. Ensure the solar panel is clean and unobstructed for optimal performance.

6. Charging External Devices

The power bank features multiple output ports for charging various devices simultaneously.

1. Open the protection cover to access the USB output ports and the Type-C input/output port.
2. Connect your device's charging cable to one of the power bank's USB output ports or the Type-C port.
3. Connect the other end of the cable to your electronic device (e.g., smartphone, tablet).
4. The power bank will automatically begin charging your device. If not, press the power button once to initiate charging.
5. The blue LED indicators will show the remaining battery level of the power bank.

7. LED Flashlight Operation

The built-in dual LED flashlight offers three modes for various situations.

1. Turn On (Steady Mode): Press and hold the power button for approximately 3 seconds. The flashlight will turn on in a steady, continuous beam.
2. Cycle Modes: While the flashlight is on, short-press the power button once to activate Strobe mode (rapid flashing). Short-press the button again to activate SOS mode (emergency beacon pattern).
3. Turn Off: From any flashlight mode, press and hold the power button for approximately 3 seconds to turn off the flashlight. Alternatively, short-press the button a third time from SOS mode to turn it off.

8. Power Status Indicators

The power bank features 5 LED indicators to keep you informed about its status:

• 4 Blue LEDs: These indicate the remaining battery capacity. Each LED typically represents 25% of the charge.
• 1 Green LED: This light signifies that solar charging is currently active.

11. Troubleshooting

If you encounter issues with your power bank, please refer to the following common solutions:

• Power bank not charging: Ensure the USB-C cable is securely connected to both the power bank and the power source. Try a different cable or adapter. For solar charging, ensure the panel is in direct sunlight and clean.
• Device not charging from power bank: Ensure the power bank has sufficient charge. Press the power button once to activate output. Try a different USB cable or output port.
• Flashlight not working: Ensure the power bank has charge. Press and hold the power button for 3 seconds to turn it on/off.
