Use a seatbelt to keep the Outsunny car freezer stuck still using the slit designed for it. Whether you're spending the day at the beach, camping with friends, or enjoying a picnic outside, the non-slip feet and seatbelt slot will keep your food safe and intact. Plug this little refrigerator for cars in at home or out of your car. Two inserts allow you to keep items in three separate areas inside. The cold -7.6 °F (-22 °C) settings keep food supremely fresh, while fridge mode saves battery.
