3. Setup and Initial Use
3.1 Initial Charging
Before first use, it is recommended to fully charge the Power Box. Connect a compatible 45W PD protocol charger to the Type-C input port (IN/OUT-1). The device supports simultaneous charging and use.

3.2 Powering On/Off
- Power On: Long press the 'ON/OFF Function Switch' button located on the front panel. The indicator light will illuminate.
- Power Off: Long press the 'ON/OFF Function Switch' button again.
3.3 Connecting Devices
The Power Box offers four output modes:
- Type-C Output (OUT-1): For devices supporting Type-C.
- USB Output (OUT-2): For standard USB-powered devices.
- PCIE Output (OUT-3): For PCIE-compatible devices.
- 4mm Banana Head Output (OUT-4): For connecting with the provided clip cable or other banana plug accessories.

Connect your device to the appropriate output port. Ensure the connections are secure before adjusting voltage or current.
4. Operating Instructions
4.1 Voltage Adjustment
The Power Box features an encoder knob for precise voltage adjustment:
- Rotate the Knob: Turn the encoder knob clockwise to increase voltage and counter-clockwise to decrease voltage.
- Fine Adjustment: Single-click the encoder knob to switch between voltage digit adjustment modes. This allows for precise adjustments in 10mV steps (0.01V).

4.2 Display Modes
The device offers three distinct display modes for monitoring output data. Press the 'Function Switch' button to cycle through these modes:
- Mode-A (Digital Display Mode): Provides a large digital display of output voltage, current, power, capacity, resistance, and energy in real-time. This mode is ideal for quick and clear data readings.

- Mode-B (Curve Display Mode): Displays current fluctuations over time in a graphical curve format. This mode is useful for diagnosing intermittent faults or observing dynamic load changes.

- Mode-C (Pointer Display Mode): Features a high-refresh-rate pointer display that mimics traditional mechanical meters. This mode allows for fault detection based on pointer oscillation, providing a familiar interface for some users.

4.3 Screen Rotation
To rotate the screen display for optimal viewing angle:
- Long press the encoder knob to rotate the screen 90 degrees.
- Repeat long presses to achieve 360-degree rotation, adjusting to your personal needs.
4.4 Power Bank Functionality
When the device is turned off, the OUT-2 USB output can still provide current, allowing it to function as a power bank for charging mobile phones and other electronic products.
5. Maintenance and Care
5.1 Cleaning
Regularly clean the exterior of the Power Box with a soft, dry cloth. Avoid using abrasive cleaners or solvents that could damage the casing or screen. Ensure no liquids enter the device.
5.2 Storage
Store the Power Box in a cool, dry place away from direct sunlight and extreme temperatures. The recommended storage conditions are between -20°C and 80°C with relative humidity below 80%. Avoid storing in environments with high moisture or corrosive gases.
5.3 Battery Care
- To prolong battery life, avoid completely discharging the battery frequently.
- If storing the device for an extended period, charge it to approximately 50-70% capacity every few months.
- Do not expose the battery to high temperatures or puncture it.
5.4 Cooling System
The intelligent active heat dissipation system automatically activates the internal fan (up to 1000r/min) when the output power is high to maintain optimal operating temperature. Ensure the ventilation grilles are not obstructed during operation.
6. Troubleshooting
6.1 "Out of Current Range" Warning
If an "Out of Current Range" warning appears on the screen, it indicates that the device is attempting to draw more current than the maximum allowed (5A). The Power Box will automatically limit the output to prevent damage. Reduce the load or adjust the voltage/current settings to resolve this.
6.2 Device Not Powering On
- Ensure the battery is charged. Connect the device to a 45W PD charger and try again.
- Verify that you are long-pressing the 'ON/OFF Function Switch' button.
6.3 Unstable Output
- Check all connections to ensure they are secure and properly seated.
- Ensure the device is operating within its specified temperature range (0°C~40°C).
- If the issue persists, contact customer support.
