Place food and drinks inside the main compartment, close the zipper and switch on the cooling unit if a power switch is present. Allow a short run time for the Peltier element to reach operating temperature; the external ventilator will distribute the cool air evenly inside the bag. Do not overload the bag to ensure proper air circulation and cooling efficiency.

Usage recommendations

For best results, pre-chill items when possible and keep the bag closed during transport. Regularly clean the interior with a damp cloth and avoid prolonged exposure to rain despite the splash-proof exterior. Use only the supplied or compatible 12 V DC power source and follow vehicle socket safety guidelines.
