TheEcoFlow Wave is a 38.5 lbs portable air conditioner. A real one. We're not talking about one of those cheapo devices where you throw in a few ice cubes, and a fan blows air over melted ice water. We're talking about a device that uses electrical power (more about that in a minute) to reduce the air's temperature substantially.
Let's start with a first impression. I pulled the machine out of its shipping carton, set it up on one of my tables in my workshop, and plugged it in. I hit the power button, and within about 30 seconds, it was blowing air in my face that was so cold that I was genuinely chilled.
To be clear, air cooling isn't just about whether cold air blows out of the front of the machine.

That's how much air can actually flow through the thing, which determines how large a space can be cooled. Another handy term is ACH, meaning air changes per hour, or how often all the air in a space can be replaced.
So, let's say you need to cool a one thousand square foot area with eight-foot high ceilings, and you want four air changes per hour. Using the handy calculator at LearnMetrics.com, you need a CFM of 553. Using the calculator on ConvertUnits.com, that's 939 cubic meters per hour.
And that, in a bit of arcane math, tells you all you need to know about the limits of the EcoFlow Wave. It can do 290 cubic meters per hour or about a third of what's needed to cool a thousand-foot space.
But do we really expect a 38 lbs device to cool a space the size of a two-bedroom apartment? No, that wouldn't be fair or realistic. My family room is roughly 18 feet by 16 feet, or 288 square feet and has a nine-foot ceiling. So, let's use our calculator on that. We need 173 CFM or 293 cubic meters per hour to do four air exchanges per hour.
Since the EcoFlow Wave handles 290 cubic meters per hour, it should be able to nicely cool a room the size of my family room, a bedroom that isn't too huge, a small home office, or any other small-to-medium sized room.
