Usage Features:
- Lightweight and Compact Design: Enhances portability for various applications.
- Pure Sine Wave Output: Provides high precision, low ripple, and SPWM voltage output, suitable for sensitive electronics.
- Multiple Output Ports: Includes AC, DC, USB (QC3.0, 5V/2A, Type-C), and wireless charging, allowing simultaneous power supply to multiple devices.
- LCD Display: Offers real-time monitoring of input power, voltage, output AC power, and battery capacity.
- LED Light: Integrated LED for illumination.
- Three Charging Methods: Supports Solar Charging, Car Charging, and AC Charging, providing flexibility in recharging the unit.
- Automatic Shutdown: The unit will automatically shut down after two minutes if no function is used, to save power.
- Cooling Fan: Activates when the internal temperature exceeds 50 degrees Celsius and the load power exceeds 20% of the rated power, or when USB charging power exceeds 5 watts.
- Protection Features: Incorporates seven safety protections: short-circuit protection, over-load protection, over-temperature protection, over-voltage protection, over-current protection, under-voltage protection, and overdischarge protection. These protections include a self-recovery function after activation.
- Charging and Inverter Interlock: The power station has a built-in protection that prevents the unit from being charged while the inverter is running. Only DC outputs will function in this scenario to prevent damage.
Maintenance Features:
- Automatic Charging Stop: The charging function automatically stops when the battery reaches 100% charge.
- Storage Recommendation: For long-term storage or transportation, the battery may enter a sleep mode. It is recommended to fully charge the product before its first use to ensure optimal performance.
- Regular Recharging: If not in use, the power station should be recharged every three months to maintain battery health.
- Operating Environment: Should be placed in a cool, dry location, away from liquids, gases, and oils, with at least 5 cm of space around it for heat dissipation.
- Overload Protection: If the startup power of a device exceeds the peak power of the power station, over-load protection will be triggered, and the power station will automatically shut down. This protects the unit from damage.
- Self-Recovery Function: After certain protection triggers (e.g., short-circuit, overload), the unit has a self-recovery function.
- Unplug Charger: After charging for 6 to 8 hours, it is recommended to unplug the charger before use.
