What size 12V fridge do I need for a weekend camping trip?

45 L is our starting size for a weekend packing test, and a hypothetical 240 Wh daily energy draw equals 20 Ah at 12 V. Food containers determine the space required; the energy figure is a calculation input, so measure actual consumption and usable battery energy before choosing a power supply.

Key facts

Fact	Value	Source
Packing-test capacity	45 L	Internal catalog reference; test your actual food
Assumed daily energy	240 Wh/day	Calculation input, not a fridge test
12 V equivalent draw	20 Ah/day	240 Wh ÷ 12 V
Two-day energy	480 Wh	240 Wh/day × 2 days
Two-day 12 V equivalent	40 Ah	480 Wh ÷ 12 V; before losses/reserve

How do I check the size before buying?

Test with the containers you actually take. Lay out the meals, drinks and any food that must remain separate, then compare their packed shape with the fridge basket. A nominal capacity cannot tell you whether a tall bottle fits.

Does a larger fridge need a larger battery?

Capacity alone does not establish energy use. Ambient heat, temperature setting, ventilation and how often you open the lid affect the result. Ask for measured watt-hours over a representative day before sizing the battery.

Do I need two cooling zones?

Choose separate zones when the trip needs separate temperature settings. ICECO lists the VL45ProS as single-zone; a larger model name alone does not establish how its compartments operate.

Worked example

Suppose your own meter records 240 Wh over a representative 24 hours. Two days need 240 × 2 = 480 Wh, equivalent to 480 ÷ 12 = 40 Ah at a nominal 12 V. Add conversion losses and a reserve, then compare against usable battery energy. This is a hypothetical meter result, not measured ICECO consumption or a promised runtime. If your measured draw doubles, the calculated energy need doubles.

Our take

We would do the packing test before buying a larger fridge. Leave room to open the lid and reach food after the rest of the truck is packed.

FAQ

Is 45 L a promise for a family weekend?

No. Meal choices, containers and drinks determine the space you need.

Can you promise a battery runtime from fridge volume?

No. Runtime needs measured consumption and usable battery energy.

Does the fridge count against payload?

Yes. Include the fridge, contents, slide and power equipment in the vehicle load check.
