- Connect the other end of the cable to a USB power adapter (not included) or a computer's USB port.
- The LED indicators will illuminate and blink to show the charging status. When all four LEDs are solid and no longer blinking, the power bank is fully charged.
Charging External Devices
- Connect your device's charging cable to one of the USB output ports (5V/1A or 5V/2.1A) on the power bank.
- Connect the other end of the cable to your device.

Operating Instructions
LED Indicator Status
The four LED lights on the power bank provide a clear indication of the remaining battery capacity:
- 1 LED solid: 0-25% capacity remaining

- 3 LEDs solid: 50-75% capacity remaining
- 4 LEDs solid: 75-100% capacity remaining
During the charging process of the power bank, the LEDs will blink sequentially to indicate the current charging segment, becoming solid once that segment is fully charged.

| Device not charging from power bank | Power bank low on battery; device's charging cable issue; device incompatibility; power bank in protective mode. | Recharge the power bank. Try a different charging cable for your device. Ensure your device is compatible with standard USB charging. Disconnect and reconnect the device to reset the power bank. |
| LED indicators not working | Power bank completely discharged; internal fault. | Attempt to charge the power bank for several hours. If the issue persists after charging, contact customer support. |
| Slow charging of external device | Using the 1A output for a device that can utilize 2.1A; low-quality charging cable; device's input current limit. | Use the 2.1A output port for faster charging if your device supports it.
