A portable freezer is a powered cooler that can hold food at freezing temperatures without ice. Most run on 12V power from a vehicle or on household current, and the better ones use a compressor like a home freezer, which keeps working in hot weather.
The six picks below are compressor-style portable fridge-freezers in a range of sizes, from compact single-zone boxes to dual-purpose models. We have not used these products ourselves. Details come from general product knowledge, so confirm capacity, power needs and dimensions on the current listing before buying.

What to Look For

| Cooling type | Compressor models freeze reliably in heat, while thermoelectric coolers cannot reach freezer temperatures |
| Capacity | Size is often given in quarts or liters, so compare it against how many days of food you carry |
| Power input | Look for 12V and household power, plus battery protection to stop the unit draining your vehicle battery |
| Zones | A dual-zone model can hold a fridge and a freezer side by side |
| Build | Strong latches, handles and tough corners matter on rough roads |
