Portable refrigerators are a good way to keep additional food cold when on the road. While many RVs come with a fridge built in, campers usually don’t. The best you might hope for is an ice box that can be stood up for fridge-like use. Fortunately, there are many different sized portable units that can be taken along to keep your food cold and fresh.
Portable fridges are typically made of high impact polypropylene and are well insulated. They even have memory functions to help them maintain the preset setting between uses. Some have wire dividers that keep foods separate as well as handles to make moving them about easy. Many can be plugged in both in a traditional outlet and a DC plug.
