That's a pretty apples-and-oranges comparison. That's a company making ridiculous promises (look ma, no external power input!) and without any third-party verification. This is a company that makes realistic claims (i.e. has actual numbers for power input per liter of water) and whose performance has been verified by the prize-awarding organization.

> has actual numbers for power input per liter of water

Where did you find that? All I could find is "0.8-1.8kW/hr" for a machine with capacity with a capacity of "30gal/day". This is complete nonsense, "kW/hr" is neither energy nor power nor energy per volume of product. And if it's power, why does it vary?

I'm going to read it as 1.8kW, with a capacity of 30 US gallons (113l) per day. My dehumidifier from the hardware store consumes 0.2kW at a capacity of 10l per day. They are 15% more productive... hardly a quantum leap.

Generally a lot of electrical appliances are advertised with kW or W actually meaning kW-hour and W-hour (and yes, this is awful, but it's pretty standard). So your interpretation as 1.8kW is about right.

It varies, as does output, because (as the numbers mention) this all varies wildly by atmospheric temperature and humidity.

(By the way, running the numbers I'm seeing it as 62.77L/kW vs. 50L/kW, which is a 25% improvement, though at much larger scale.)

I'm not endorsing it, just posting, i have not yet see the video.
