Operating Instructions
Charging Devices
- Using Built-in Cables: Select the appropriate built-in cable (USB-C, iOS, or USB-A) and connect it directly to your device. The power bank will automatically begin charging.
- Using USB Ports: For devices requiring other cable types, use your own USB-A or USB-C cable and connect it to the corresponding output port on the power bank.
- Wireless Charging for Apple Watch: Place your Apple Watch on the designated wireless charging pad on the power bank. Ensure the watch is properly aligned for charging to begin. This feature is compatible only with Apple Watch models.

Solar Charging (Backup Method)
The integrated solar panel is designed for emergency charging and maintaining battery life in outdoor environments. For primary charging, always use a wall adapter. Place the solar panel directly under strong sunlight. The blue LED indicators will light up to show solar charging activity. Solar charging efficiency depends on sunlight intensity and angle.

Using the Flashlight and Camping Light
- Flashlight: Press the power button once to turn on the flashlight. Subsequent presses will cycle through brightness modes (Low, Medium, High) and then turn off.
- Camping Light: Press and hold the power button to activate the camping light. Subsequent presses will cycle through brightness levels and then turn off.
Maintenance
- Cleaning: Wipe the power bank with a soft, dry cloth. Avoid using harsh chemicals or abrasive materials. Ensure all ports are dry before use.
- Storage: Store the power bank in a cool, dry place away from direct sunlight and extreme temperatures. For long-term storage, charge the power bank to approximately 50-70% every three months to preserve battery health.
- Water Exposure: While the device is waterproof, avoid prolonged submersion. Ensure all port covers are securely closed when exposed to water.
Troubleshooting
- Device not charging from power bank:
- Ensure the power bank has sufficient charge.
- Verify the cable connection is secure and the cable is not damaged.
- Confirm the correct cable type is used for your device.
- For wireless charging, ensure your Apple Watch is correctly positioned on the charging pad.
- Power bank not charging:
- Check the charging cable and wall adapter for damage.
- Ensure the USB-C input port is clean and free of debris.
- For solar charging, ensure direct and strong sunlight exposure. Remember solar charging is a backup method and slower than wall charging.
