Setting up a portable AC car unit is a good option for older vehicles that may not have been manufactured with modern cooling systems. One such example is the Arctic Air Portable Airplane Air Conditioner 12 Volt 30 Qt.
This particular device can be attached to any cooler with a 16.25″ by 9″ opening. The main compartment can be packed with ice, then the 12-volt adapter can be plugged into the car’s cigarette lighter. This type of AC unit is also lightweight, portable and easy to maintain.
Another similar car cooling option is the Arctic Air Portable Airplane Air Conditioner 12 Volt 52 Qt Dual Fan, which has an MSRP of $495 plus shipping and handling costs. It was originally designed to cool the interiors of smaller-sized airplanes, but it can be just as effective at cooling off larger vehicles.
This portable AC unit is larger and more expensive than some others, it can be used to cool of car interiors, homes, or practically any other inside space during the hot summers. All it requires is access to a 12-volt wall outlet. A recommended 12-volt wall to AC adapter is the Brackerton Travelers AC Adapter.
