4.2 Placement
- Place the refrigerator on a flat, stable surface.
- Ensure there is adequate ventilation around the unit, especially near the air inlets and outlets. Do not block these openings.
- Avoid placing the refrigerator in direct sunlight or near heat-generating appliances.
- The unit can operate normally even when tilted up to 45 degrees, making it suitable for various vehicle conditions.
4.3 Power Connection
The refrigerator can be powered by either AC or DC sources:
- AC Power (Home Use): Connect the AC power adapter to the refrigerator's AC input port, then plug the adapter into a standard 100-240V AC wall outlet.
- DC Power (Vehicle Use): Connect the DC car cigarette lighter power cable to the refrigerator's DC input port, then plug the other end into your vehicle's 12V or 24V cigarette lighter socket.
Important: Do not connect both AC and DC power simultaneously. The refrigerator will automatically prioritize AC power if both are connected, but it is recommended to use only one source at a time.

6.3 Storage
If storing the refrigerator for an extended period:
- Ensure the unit is clean and dry.
- Leave the lids slightly ajar to prevent odors and mold growth.
- Store in a dry, well-ventilated area, away from direct sunlight and extreme temperatures.
