Those looking for mobile cooling for heat waves, camping and the like will be in good hands with the EcoFlow Wave 3. We recently reviewed the portable air conditioner in order to determine its strengths and weaknesses.

The heat waves of the past few days in Europe and North America have mostly subsided for the time being. Anyone looking to prepare for another round of extreme temperatures or doing some research on portable air conditioners will likely come across the EcoFlow Wave 3.

We've been testing this portable air conditioner over the past few weeks and have compiled all the results in our review. The EcoFlow Wave 3, which can be controlled via app, performs well in some areas, provided you pay attention to certain things and don't have too high expectations.

If you're hoping to cool down large rooms in midsummer, the Wave 3 is definitely not the right choice. This portable solution is only suitable for small rooms, namely a maximum of 17 square meters (around 183 square feet). As long as the room size does not exceed this limit, users can expect effective cooling, especially compared to the predecessor. It can provide more pleasant temperatures in small bedrooms in the summer in the evenings and also offers a quiet night mode for light sleepers.

The EcoFlow Wave 3 is primarily intended as a mobile solution for camping, motorhomes and the like. However, if the sun beats down on the vehicle roof during the day, the Wave 3 isn't powerful enough to provide any noticeable cooling effect. In the evening, on the other hand, it can lower room temperature to pleasant levels in a motorhome, caravan or even a tent. Interested parties can read our EcoFlow Wave 3 review for more details.

The Wave 3 is currently on sale directly from the manufacturer at $899, down $400 from the RRP of $1,299. However, it then requires a power outlet or power station. For mobile and independent use, EcoFlow offers an add-on battery, which costs an additional $500, making the portable air conditioner rather expensive overall.
