EcoFlow Wave Portable Air Conditioner Review: Keeping Cool The Green Way – SlashGear

The EcoFlow Wave is rated with a cooling power of 4,000 BTU, and it's advertised as able to cool a small area in just 8 minutes. Of course, that speed will depend largely on how wide the space is, and those figures were calculated for an area of 8 square meters. That's about the size of a four-person tent, so small bedrooms and small offices are a piece of cake for the Wave. EcoFlow says you can even use it outdoors in the open air, though its cooling efficacy will definitely take a hit.

If you do need to have the cold air directed to a specific location, you can easily attach the cold-end outlet shroud in the front. Like all air conditioners, the Wave works best if hot and cold air don't mix, which might be difficult if the hot air is also being pushed out in the same room. With that said, the cold air that the portable A/C does push out overpowers the hot air that it produces. If you really want maximum efficiency, though, you can attach the hot-end shroud to the back and have the two hoses directed to a different area outside of the room or tent. That's not necessary, but the option is there if you have a way to pump the hot air outside of the room, such as through a window or other opening.

Another typical consideration for A/Cs is the water condensation they produce. Most of the time, this requires that a hose be connected to drain the water, which can be inconvenient for portable air conditioning units. This is where the EcoFlow Wave's smart design comes in. Depending on where you live or how you're using it, you might not have to drain it at all. The Wave takes the water it produces and sprays that onto the internal condenser, making it evaporate on its own while cooling the component in the process. This works best in low-humidity environments where water buildup is minimal.

In high-humidity locations, you might need to drain the water manually by connecting a hose to the drainage outlet. The hose doesn't need to be connected all the time, though, and the A/C will automatically turn itself off if its water basin is full and there is no hose connected. This failsafe lets you use the Wave without cables or hoses for a period of time, allowing you to drain the water at your own convenience.
