Cooling Fan for Desk and Car - Portable Evaporative Air Cooler for Camping - Small Ice Fan for Tent - Personal Air Conditioners Evalight, Blue

Love this thing. Doesn't use too much power, so it works well for portability if you combine it with a power bank. The OEM filters are pricey. Good luck finding one that is compatible.

I live in a large studio with high ceilings in a big city that gets really hot in the summertime. My portable AC unit gave out and I didn't want to replace it. At the end of its days, it was working pretty terribly to begin with. I split my time between my place, my office, and my boyfriend's place. I bought the EvaLight and turned it on last night. Not only did it cool off my living room, it also cooled off my bedroom area when I turned it towards that area, and kept it cool all night. I just ordered an EvaChill so I can cool the place down even more. I have the windows open and a ceiling fan going and it has been more than reasonable in my apartment with the EvaLight despite it being hot outside. I'm not getting another portable AC unit.

I have sensory issues and cannot tolerate the 80-100 degree temps my coffin-sized apartment gets almost year round so I bit the billet and purchased this overpriced swamp cooler. I say cooler lightly since it’s just slightly colder than skin temp moist water blowing on you for about a couple hours until the water runs out (nowhere close to the 8 hours they promise). You’re left feeling sticky and gross which is better than dying of heat exhaustion I guess.Another let down is the fact that this “touch screen system” isn’t a touch screen at all… it’s a button with a ring slider that you move manually. Their marketing led me to believe it would have some swanky touch screen system but it’s archaic. I owned the smaller Evapolar (also a rip-off) and it has basically the exact same mechanics and features. They added a little LED screen and some primeval color customization to try and justify the $60 markup.I seem so negative which begs the question as to why I’m keeping it:1) They use basalt, which is apparently safe for breathing. No other swamp cooler on Amazon mentions anything about their internal materials being safe for breathing so that scared me into placing my trust in this company (I’m immunocompromised).2) My apartment refuses to install AC and I have no compatible windows for a portable AC unit so I’m stuck with using swamp coolers.If you are able to use a portable AC unit, do that. If you’re not immunocompromised and don’t care about breathing other materials, choose any other swamp cooler. They all looked much bigger and more powerful at competitive prices. Just don’t get this joke of a “cooling” system.

I purchased this for burning man, I'll update my review afterwards.The humidity today is 44%. Temperature was rising, and when the room temperature reading went from 81 degrees to 82, and the temp of air coming out went from 71 to 72, I turned on my actually air conditioner in my apartment.What I'm seeing here in Los Angeles is that I get the low-end of performance, only ~10 degrees of effective cooling, at the bottom of the claimed 9-25 degrees possible. This is mildly disappointing, but not a deal-breaker. Burning man should have higher temperatures and no humidity, so I'm very keen to see how effectively it cools my tent.Other things to note. The unit design is pretty solid. It looks nice, the control wheel and TouchPad work as an interface, the light being integrated into the water tank is a nice touch. As others have noted, the fan is hardly whisper quiet but that's just how fans are.I'm most happy to report that it actually draws only 4-5W of power at maximum fan speed, and only 2W at half-power (which is the most effective setting for balancing ambient noise and cooling effect). This means I can run this thing for hours and hours off of a battery power source, good for the off the grid application I need it for.All in all, this is a slick-looking unit with some well designed features and anesthetics. It's held back by the inherent limitations of evaporative cooling. If you live in a humid place, you don't want to buy this.I do think it's a little overpriced though. This is the same working principle as a swamp cooler, something you can make yourself pretty cheaply and might actually be more effective than this.In shortGood product, mediocre value
