You do not need a premium overlanding fridge for a camping weekend or a long drive. Budget-friendly portable fridges use either a compressor or thermoelectric cooling, and the right choice depends on how cold you need food and how hot the weather gets.
The six picks below include compressor boxes that can chill or freeze and thermoelectric coolers that simply keep things cool. We have not used these products ourselves. Details come from general product knowledge, so confirm cooling range, power needs and dimensions on the current listing before buying.

What to Look For

| Capacity | Size is given in quarts or liters, so match it to how many people and days you plan for |
| Power | Look for 12V for a car socket and household power if you want home use too |
| Weight | Lighter coolers are easier to load, but compressors weigh more than thermoelectric boxes |
| Noise | Compressors cycle on and off, while thermoelectric fans run all the time |

Can a budget fridge freeze food?
Compressor models often can. Thermoelectric ones cannot.
Do they work on a car battery?
They run on 12V, but leaving them on with the engine off can drain the battery.
How long do they take to cool?
It varies by model and outside heat, so pre-chill the unit for best results.
