- Power Switch: Toggles the power bank on/off. Must be in "on" position for charging.
- 12V IN/OUT Port (DC 5525): Used for charging the power bank (input) and providing 12V DC output.
- 5V USB OUT Port: Standard USB-A port for charging 5V USB devices.
- 9V OUT Port (DC 4017): Provides a constant 9V DC output.
- LED Power Indicators: Four blue LEDs indicate the remaining battery capacity (25%, 50%, 75%, 100%).
Setup and Initial Charging
Before first use, fully charge the power bank.
- Connect the Charger: Plug the provided 14.6V AC/DC charger into a wall outlet. Connect the charger's DC output plug to the 12V IN/OUT port (DC 5525) on the power bank.
- Activate Charging: Ensure the power switch on the power bank is in the "on" position (indicated by "-"). The LED indicators will illuminate, showing the charging progress.
- Full Charge Indication: All four LED indicators will be solid blue when the power bank is fully charged. Disconnect the charger once charging is complete.
Note: If the power bank is not charging, verify that the power switch is in the "on" position.
Operating Instructions
Powering On/Off
- To turn on the power bank, slide the power switch to the "on" position (-). The LED indicators will show the current battery level.
- To turn off the power bank, slide the power switch to the "off" position (O).
Using DC Outputs (12V, 9V)
- 12V DC Output: Connect your 12V device to the 12V IN/OUT port using the appropriate DC 5525 cable. The 12V output voltage range is 10V to 14.6V and is not constant. Ensure your device is compatible with this voltage range.
- 9V DC Output: Connect your 9V device to the 9V OUT port using the appropriate DC 4017 cable. This output provides a constant 9V.
- Important Note for 9V Devices: The power bank's DC ports have an inner positive (+) and outer negative (-) polarity. Many guitar pedals and similar devices have reversed polarity (inner negative, outer positive). You may require a reversed polarity cable (not included) to connect such devices. Verify your device's polarity requirements before connecting.
Using USB Output (5V)
- Connect your 5V USB-powered device (e.g., mobile phone, tablet) to the 5V USB OUT port using a standard USB cable. This port provides a constant 5V output.

Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Power bank not charging. | Power switch is off. Charger not connected properly. Faulty charger/cable. | Ensure power switch is in "on" position (-). Reconnect charger securely. Try a different compatible charger/cable if available. |
| Device not charging from power bank. | Power bank is off. Low battery on power bank. Incorrect cable/port. Device incompatibility. | Turn on power bank. Check LED indicators for battery level; recharge if low. Ensure correct DC or USB cable is used with the correct port. Verify device voltage/polarity requirements. |
| 9V device not working (e.g., guitar pedal). | Polarity mismatch. | The power bank's DC port is inner positive (+), outer negative (-). Many guitar pedals are inner negative, outer positive. A polarity reversal cable may be required. |
