AC Charging: Connect the included AC adapter. Charging time: ~7 hours.
Solar Charging: Connect compatible solar panel (11-60V DC) to the DC INPUT port. Use MPPT for efficiency.
Car Charging: Connect the 12V car charger cable to the car socket and the DC INPUT port while driving.
Status: LCD shows input power (Watts) and estimated time to full charge.
Battery Care: For longevity, avoid draining the battery below 10%. Store at 50-80% charge if not used for long periods.

WARNING! Use only the provided or manufacturer-approved charging cables. Do not charge in extreme temperatures.

Safety Features

Overload Protection: Automatically shuts off output if exceeded. Thermal Protection: Reduces power or shuts down if overheated. Short Circuit Protection: For all output ports. Low Voltage Disconnect: Protects battery from deep discharge.

Care & Maintenance
