Operating Instructions
Powering On/Off
Locate the ON/OFF switch on the top panel. Flip the switch to the "ON" position to activate the integrated ports and digital voltmeter. Flip to "OFF" when not in use to conserve battery power.
Using the Digital Voltmeter
The digital voltmeter displays the current voltage of the installed battery. This allows you to monitor the battery's charge level. A fully charged 12V battery typically reads around 12.6V to 12.8V. Consult your battery's specifications for optimal voltage ranges.
Charging Devices via USB (QC3.0 & PD Type-C)
Connect your mobile phones, tablets, or other USB-powered devices to the QC3.0 or PD Type-C ports. These ports provide fast charging capabilities for compatible devices.

Powering 12V Appliances (Cigarette Connector)
Plug your 12V appliances (e.g., portable refrigerators, air pumps) into the 12V cigarette connector. Ensure the total power draw of connected appliances does not exceed 100W to prevent overloading.
Using Anderson Connectors
The two 50 Amp Anderson-style ports can be used for high-current applications, such as charging the battery from a solar panel or vehicle alternator, or powering high-draw 12V equipment. These ports are protected by a 60A fuse.
To charge the internal battery using solar panels, connect the solar panel's Anderson connector to one of the battery box's Anderson ports. Ensure your solar panel has a compatible charge controller.

Maintenance
- Regular Cleaning: Keep the exterior of the battery box clean and free from dust and debris. Use a damp cloth for cleaning. Avoid harsh chemicals.
- Terminal Inspection: Periodically check all external and internal connections for tightness and corrosion. Clean any corrosion with a wire brush and battery terminal cleaner.
- Storage: When not in use for extended periods, store the battery box in a cool, dry place. Ensure the internal battery is fully charged before storage and periodically recharged to prevent deep discharge.
- Circuit Breaker: If the 16 Amp resettable circuit breaker trips, disconnect some loads and press the reset button. If it continues to trip, reduce the load or investigate for a short circuit.
