The HiKOKI UL 18DF is a versatile cordless cooler and warmer box designed for private use in camping, vehicles, or similar environments. It can be powered by an 18V battery, a 12V vehicle cigarette lighter socket, or 230V mains power (using the provided AC adapter).
Device Overview
The device features a rotary knob for power control, an operating mode switch (warm/cold), and a 24L capacity container. It is equipped with ventilation slots to ensure proper air circulation.
Setup and Installation
- Carry Handle: Insert the carry handle at the indicated angle, first on one side by inserting the nose into the rectangular opening, then on the other side while pulling the handle slightly apart.
