Whether you are taking the family on a short day trip in the car, or heading out to the cottage for a long weekend, a 12 volt car cooler comes in handy as a way to keep cold beverages, snacks and sandwiches cool throughout the trip. Some car coolers even perform double duty as both a cooler and a heater, keeping warm food warm. Make sure to buy a cooler that comes with an AC adapter so that you can use the cooler at the cabin or campsite in lieu of a fridge.
