When you think of camping in the UK, the first things that come to mind are beautiful landscapes, unpredictable weather, and the joy of disconnecting from the hustle of everyday life. But while the UK is known for its mild summers, heatwaves are becoming more frequent — and when you’re sleeping in a campervan, caravan, or even a tent, a hot and stuffy night can make you feel more exhausted than refreshed. A Camping AC is what you need or in other words a small portable conditioner.
Enter the EcoFlow WAVE 3 — a powerful, portable air conditioner designed for adventurers, off-grid explorers, and anyone who wants cooling comfort without being tied to mains power. It’s compact enough for home use, reliable enough for camping, and smart enough to run off multiple power sources.
Let’s take a closer look at why the EcoFlow WAVE 3 is one of the most dependable portable AC units you can buy — and why it’s especially suited to campers in the UK.
Why Campers in the UK Need a Portable AC
Most people don’t associate UK camping with extreme heat, but anyone who’s spent a summer night in a small campervan will tell you: heat builds up fast in enclosed spaces. During the day, sunlight turns a van or caravan into an oven. At night, the heat lingers, making it hard to sleep.
The problem is, traditional air conditioners are bulky, noisy, and require constant mains power. For many UK campsites — especially off-grid or festival spots — that’s simply not an option. This is where a battery-powered, portable AC like the EcoFlow WAVE 3 changes the game.
Key Features of the EcoFlow WAVE 3
1. Powerful Cooling in a Small Package
The WAVE 3 delivers up to 5,100 BTUs of cooling — enough to quickly lower the temperature in a small caravan, campervan, or tent. It’s engineered for fast cooling, meaning you’ll feel relief within minutes rather than hours.
2. Multiple Power Options
One of the biggest advantages of the WAVE 3 for campers is its versatile power capability. You can run it:
-
Directly from a wall socket when you have mains power.
-
From a solar generator or battery pack for true off-grid camping.
-
Via a car outlet while traveling.
Pairing it with an EcoFlow DELTA 2 or DELTA Pro portable power station gives you hours of runtime without needing to be hooked up to the grid.
3. Long Battery Life & Fast Charging
With the optional add-on battery, the WAVE 3 can run for up to 8 hours in eco mode. And when it’s time to recharge, EcoFlow’s fast-charging technology means you can get back to full power in just a couple of hours.
4. Designed for Portability
Weighing around 14.5 kg, the WAVE 3 is compact and easy to move. The design includes integrated handles for carrying, and its footprint is small enough to tuck away in your van when not in use.
5. Quiet Operation
Noise is a big deal for campers — nobody wants to trade heat for the sound of a jet engine. The WAVE 3 runs at as low as 44dB in sleep mode, making it quiet enough to run overnight without disturbing you or your neighbours.
6. Eco-Friendly Cooling
EcoFlow has designed the WAVE 3 with R290 refrigerant, which is more environmentally friendly than traditional refrigerants, aligning with the brand’s commitment to sustainable technology.
EcoFlow WAVE 3 vs Other Portable AC Units
Many small portable air conditioners either lack cooling power or require constant mains power. Here’s how the WAVE 3 stacks up:
| Feature | EcoFlow WAVE 3 | Typical Small Portable AC | Basic Fan Cooler |
|---|---|---|---|
| Cooling Power | 5,100 BTUs | 2,000–3,000 BTUs | N/A (no true cooling) |
| Power Options | Mains, battery, solar, car | Mains only | Mains or battery |
| Portability | 14.5 kg, carry handles | 20–30 kg, bulky | Lightweight |
| Runtime Off-Grid | Up to 8 hours | None | Several hours |
| Noise Level | ~44dB in sleep mode | 50–60dB | Quiet |

Why It’s Great for Home Use Too
