Buying Guide
Cooling capacity (BTU/kW)
Choose a unit with the right cooling output for your motorhome or caravan — too small and it won’t cool, too large and it will short‑cycle. Look at BTU/h (or kW) ratings and match to the van’s habitable area and insulation; typical portable units for campervans range from about 8,000–14,000 BTU.
Power supply and current draw
Check whether the AC will run from campsite 230V hook‑up, an inverter or your leisure battery — most portable air conditioners need a substantial draw and may trip a standard 13A socket. Look at amps, input watts and whether you have reliable mains or a high‑capacity inverter before buying.
Venting, installation and compatibility
Portable units need an exhaust outlet — single or dual‑hose kits — and you’ll want to know how the exhaust will fit a van window, roof vent or tailgate. Consider whether a rooftop unit (like Dometic) or an indoor portable with a bespoke venting kit better suits your vehicle and whether you want a semi‑permanent installation.
Noise and size
Noise is important in a small living area. Check official dB ratings and user reviews for in‑use noise; also consider the unit’s physical size and weight so it fits the space and is manageable to move and store when travelling.
Drainage, dehumidification and energy efficiency
Portable ACs produce condensate; some auto‑evaporate, some need manual draining or a continuous drain hose — vital for longer stints. Also compare EER/energy use to estimate campsite electricity costs and how frequently the unit will cycle on in humid UK summers.
Frequently Asked Questions
What is the best portable air conditioner for an RV in 2026?
There’s no single best model for every van — it depends on vehicle size, power availability and budget. For powerful cooling many motorhome owners favour dual‑hose models such as the Whynter ARC series for efficiency; for quieter operation the De'Longhi Pinguino line is often recommended, while Dometic roof units suit those wanting a permanent install. Check current 2026 reviews and confirm power draw and venting needs before deciding.
Is a portable air conditioner for an RV worth buying in the UK?
It can be worth it if you regularly camp in warm weather, sleep in places without shade or need rapid cooling after driving. Bear in mind campsite electric hook‑ups and inverter capacity — if you mostly wild‑camp or rely on batteries, a portable AC may be impractical without significant power upgrades.
Which portable AC offers the best value for money for a caravan?
Value depends on your priorities: for raw cooling per £, dual‑hose Whynter models often give good capacity for the price, while De'Longhi units tend to be quieter and more refined but cost more. Shop around retailers such as Amazon UK, Argos or specialist camping suppliers and compare seasonal deals in GBP.
Dometic vs Whynter — which should I buy for a motorhome?
Dometic specialises in vehicle‑specific roof or built‑in units that integrate neatly and run efficiently from campsite power; choose Dometic if you want a permanent fit. Whynter produces portable dual‑hose machines that are strong and flexible for temporary use — pick Whynter if you need portability and lower upfront installation cost.
Can I run a portable AC in a campervan from my leisure battery or a typical inverter?
Most portable air conditioners require significant wattage and will overload a standard leisure battery/inverter setup; they generally need a reliable 230V mains supply or a heavy‑duty inverter and large battery bank. Always check the unit’s continuous power draw in watts/amps and compare with your system limits.
Do I need a dual‑hose portable air conditioner for my RV?
Dual‑hose designs are more efficient in enclosed spaces because they draw outdoor air for cooling and expel warm air separately, reducing negative pressure and run time. If you’ll be cooling a larger or poorly ventilated motorhome, dual‑hose is preferable; for very small vans a single‑hose unit can still work but may be less efficient.
What about evaporative coolers (swamp coolers) for vans in the UK?
Evaporative coolers are inexpensive and energy‑light but only work well in dry climates; the UK’s often humid summers limit their effectiveness. For most UK motorhome users, a refrigerated portable AC or a rooftop unit will give more reliable cooling.
Where can I buy a portable air conditioner for an RV in the UK?
You can buy from mainstream retailers like Amazon UK, Argos and Currys, or from specialist camping and motorhome suppliers such as Camping World and Go Outdoors. Check warranties, return policies and whether the retailer stocks venting kits compatible with your vehicle.
