Choose how the fridge will fit and be used before comparing the litres on a product listing. A portable top-opening fridge and a built-in front-opening model can both suit a campervan, but they make different demands on the layout.
This guide compares two manufacturer-described examples. It does not claim measured cooling performance, noise or daily consumption.
Compare two arrangements
| Example | Published capacity and supply | Useful starting point | Layout question |
|---|---|---|---|
| Dometic CFX5 35 | 36 litres; 12/24V DC and mains input | A portable chest-style compressor fridge | Can you open the lid without moving the bed or worktop? |
| Vitrifrigo C51i CHR | 51 litres total; 12/24V DC | A fixed front-opening cabinet | Is there room for the door, installation clearances and service access? |
Dometic's UK specifications identify the CFX5 35 as a 36-litre compressor coolbox. The model number is not its capacity. Check the exact SKU and current manual when comparing bundles.
The Vitrifrigo manufacturer catalogue lists the C51i CHR as a 51-litre unit including a small freezer compartment. Other C51 variants have different arrangements: do not use one variant's drawing to cut cabinetry for another.
Measure access as well as the appliance
Create a simple mock-up in your proposed location. Open the adjacent drawers, bed panels and doors. Imagine removing a bottle or cleaning a spill when someone else is in the van.
Confirm the complete installation dimensions with the model's instructions. The outline dimensions do not include every required clearance, cable bend or fixing arrangement. Secure the equipment for travel using an appropriate manufacturer-supported installation.
Plan energy from daily consumption
A compressor runs intermittently. Multiplying a maximum input rating by 24 hours does not establish ordinary daily demand. Equally, a low consumption figure from controlled conditions is not a guarantee for a hot van.
Check the conditions attached to any published energy figure. Your set temperature, ventilation, ambient conditions and use can differ. Measure a representative day where possible, and include the fridge in your daily-power worksheet.
Follow the manual for electrical supply and ventilation. Do not improvise a fixed connection from the fact that the label says 12V. Include appropriate design and installation work in the total cost.
Keep food storage separate from the sales claims
The Food Standards Agency's household guidance recommends a fridge temperature between 0 and 5°C and using a fridge thermometer to check it. Follow food storage instructions and use-by dates; a cold-looking display does not establish that every item is stored correctly.
Choose enough usable space to organise the food you actually carry. Avoid selecting a fridge entirely around a can-count claim or a photograph of an unusually packed interior.
Before buying
Confirm the exact model, supply cables, installation drawing, mounting accessories, warranty eligibility and return conditions. Compare the installed cost with your layout and charging plan.
