Evapolar evaCHILL Portable Air Conditioners - Portable AC Unit - Small Personal Evaporative Air Cooler & Fan for Desk, Office, Car, Camping, White

I recently ended up with a $900 electric bill thanks to a week of 110 degree days in sunny California, so I decided to look into some alternatives to running central air all day. This little guy seemed to be the most well-reviewed out of all the options for portable air conditioners even though it still had an overall 3.6 rating, but I decided to give it a try.Having tested it out, I gotta say it actually works better than expected and I think some of the negative reviews have had issues for easily avoidable reasons.1) This is not made to cool an entire room. That's not the point of it. This is for someone who wants to cool down their bed while they're sleeping or set it on their desk to cool down while they're working or maybe place in a corner of the kitchen while cooking. Basically, it's for when you're spending a lot of time in roughly the same spot and don't necessarily need to cool down your entire house.2) it doesn't work wonders for the first 20 minutes or so. The water needs to soak through the filter cartridge because the water evaporating in a (ideally) dry climate is the science behind cooling the air. Until that happens it's basically just a little box fan. I get the impression some reviewers tested it out for 5 minutes, concluded it doesn't work, and wrote their review. Give it at least 20 minutes and you should definitely notice that it's pushing out air a good 8-10ish degrees cooler than the room temp is.3) because this relies on water evaporating, it works better in drier climates. If you're in California, Arizona, New Mexico, etc this will work great. If you're in a humid place like Florida, you should frankly leave.4) Based on what some have mentioned in terms of its air pushing capabilities, it seems like they maybe don't realize there are multiple settings. At its lowest setting I would say they're right: you basically need to have it within 12 inches of you to even notice it's on. However it has 4 settings that you cycle through by pushing the button on top (and there are no other buttons, it's pretty fool-proof). I think the 2nd setting is probably what most people would use while sitting it on their desk or beside their bed (higher settings might actually make you cold at that proximity). At its highest setting it's a bit noisy (like a PC fan at full speed), but I think it would actually be sufficient to cool a *small* bedroom at that level. If you have something like a 10×10 space or smaller and you don't have high ceilings, this might actually work for cooling the entire room at its highest setting. In a larger space, however, just remember this is made to cool you down while having it a few feet from you, not on the opposite end of where ever you are. I just did a little test and you can feel a cool breeze from 8 feet away at its highest setting. Beyond that you probably won't notice much effect.Also, I didn't notice this when I bought it, but it plugs in using a USB cord so you can power it with your computer or plug it into a power bank and take it on the go. It also only uses 7.5 watts which is literally 3,492.5 watts fewer than the average Central air system. That's not a joke or a typo. On a related note, I've seen some claim the price ($79 as of writing) is a bit steep, but consider that for anyone who works from home or stays in the same area for large parts of the day, this will allow you to kick the thermostat up a few degrees without sweating through your shirt, and then you'll save pretty substantially on each electric bill. It can pay for itself in one billing cycle if you let it, and after that it's actually costing you money not to have one.Overall, I'm perfectly satisfied with this purchase and it actually performs better than reviews had led me to believe. Just remember it's made to cool a roughly 10×10 area or smaller, not your entire estate. If you're ok with that, you'll love it.

My husband sleeps very warm. Even in winter he has the fan blowing on him. I bought this for him for Father's Day and I set it up yesterday. It isn't hard to set up and tried it out without the water first. I was quite surprised and pleased to see the power that little fan has. The "nite lite" is a nice feature but not one he will use. I'm glad there is the option to turn the lite off. So far, no water leaks and it fits nicely on the nightstand. The only thing I am not sure of is how much water to put, I didn't see a fill line, but my common sense told me how much to fill it. I am pleased with everything so far and am waiting for my husband to start using this.

Absolutely useless . I hate myself for buying this and getting tricked into buying this useless junk. A regular desk fan is way more cooling than a this. The fan is weak, it’s extremely loud, has a constant annoying blue neon light on to give you the illusion that it’s cold when it’s really not. The plug is USB powered only and the filter that came with is just a bunch of cardboard sheets layered on top of each other. This whole thing is a joke, I’m upset at myself for believing I could get a semi decent personal ac at this price.Please do not buy this, just buy a fan. It does the same job if not better at keeping you cool. Also I tested this in my small room office by leaving it on all day with windows and door closed on 65 degree day and the room was just still hot lol. Very disappointing.

It works 100 percent, I don’t hardly leave reviews but going on 6 hours and my mobile battery fan battery hasn't budge still fully charged, it wastes hardly any battery. It could be run with the small battery bank, Hold power button few seconds to turn off light while running. It will work great in van sleeping cooling off small area quick. People who say don’t work I believe they didn’t take the paper wrap of carton filter.
