How to choose the right capacity ?
Large fridges mean greater capacity, but higher current draw, and they'll take up more space in your car. With a whole family plus gear already onboard, a fully loaded fridge could push your car over its gross vehicle mass (GVM). Expansion inserts are also available for some fridges, clipping onto the top for additional capacity when you need it.
Sizes are listed in litres, but this can be hard to visualise so we've included a universally recognised unit of measure – cans of drink.
30L & under – 27 cans: Essentially a powered cooler, these compact fridges are suitable for keeping lunch cold in a work truck for you and your offsider. They're also a good option if you need to keep medicines refrigerated and close to hand.
40L – 60 cans: The most common or 'standard' size, 40L fridges are great for two or three people for a long weekend.
50L – 72 cans: Suitable for a whole week adventure for two, or a long weekend for a family.
75L – 113 cans: A good size fridge for a family of five, or providing sustenance for your sporting team. There's plenty of room to keep the team's half-time oranges on ice, but consider the space it takes up in your vehicle, and the weight.
100L+ – 150 cans: Plenty of space for a week away with a big group, but size and weight may be a serious consideration. You could be better off sharing the load between smaller fridges and separate vehicles.
