How to use

Place the Ravanson CS-28S Super on a stable, level surface inside the vehicle or at your campsite, ensuring adequate ventilation around the unit.

Pre-cool the unit before adding highly perishable items for best results, and arrange contents to allow air circulation inside the compartment. Monitor power source and vehicle battery state during DC use to avoid excessive battery drain.
