3. Power Connection:
   • DC Power (12V/24V): Connect the DC power cable to the refrigerator's DC input port and then to your vehicle's 12V/24V outlet (cigarette lighter socket).
   • AC Power (100-240V): Connect the AC power cable to the refrigerator's AC input port and then to a standard wall outlet.
4. Ventilation: Ensure there is at least 10 cm of clear space around all sides of the refrigerator for proper ventilation.
