AC Charging: Use included AC adapter; plug into wall outlet and unit's AC input port.
Solar Charging: Connect compatible solar panel (12-24V, max 150W) to solar input port.
Car Charging (optional): Use 12V car charger adapter plugged into vehicle's 12V outlet.
Charging Status: LCD shows charging icon and estimated time to full.
Fast Charge: Supports up to 3A input for quicker charging.

WARNING! Use only recommended charging accessories. Do not charge in temperatures below 32°F or above 104°F.

Safety Features

Overload Protection: Automatically shuts off output if load exceeds rating. Short Circuit Protection: Cuts power on short circuit. Temperature Control: Fan cools during high load/charge; shuts down if overheated. Low Voltage Protection: Prevents battery damage by cutting off at 10V. Battery Management System (BMS): Monitors cell voltage, temperature, current.

Care & Maintenance

Store in cool, dry place. Clean with dry cloth; do not use liquids. For long storage, charge to 50-60% and recharge every 3 months.

CAUTION! Do not disassemble; no user-serviceable parts inside. Avoid dropping or mechanical shock.
