Connecting Devices

AC Devices: Plug into AC outlet (max 450W). DC Devices: Use carport or 5.5mm DC port. USB Devices: Connect to USB-A or USB-C ports.

Check device power requirements (watts/amps).
Ensure total load does not exceed 450W AC or DC limits.
Turn on generator first, then connect devices.
Select correct output mode (AC or DC) for connected devices.

Tip: For high-power devices, ensure battery has sufficient charge to prevent shutdown.

Charging & Power Management

Supports AC charging, solar charging, and car charging.

AC Charging: Use included AC adapter for fastest charging (0-100% in X hours).
Solar Charging: Connect compatible solar panel; MPPT optimizes efficiency.
Car Charging: Use 12V car charger cable (optional accessory).
Battery Care: Avoid complete discharge; recharge when below 20%.
Power Saving: Enable auto-shutdown in settings to conserve battery.
Parallel Connection: For higher capacity, connect multiple units (if supported).

WARNING! Use only approved charging sources. Do not charge in extreme temperatures.

Safety Features

Overcharge Protection: Stops charging at 100%. Overload Protection: Shuts off output if exceeded. Short-Circuit Protection: Cuts power during short circuit. Temperature Control: Reduces power if overheated. Low Voltage Protection: Shuts down to prevent battery damage.

Care & Maintenance

Store in cool, dry place. Clean with dry cloth; avoid liquids.

CAUTION! Do not expose to rain or moisture. Keep away from flammable materials.
