CoolCove Plug-In Air Conditioner Delivers Cheap and Effective AC as Advertised, According to One Independent Tester and Online Product Reviews: It Is Also a Ceramic Heater: However, There are Also Complaints That It Does Not Cool Effectively and Offers No More Cooling Than a High-End Fan Does

     While I am happy with my whole-house mini-split heat pump AC system, this new product seems to be an authentic breakthrough in affordable, effective, and simple-to-install air conditioning, although single units are only good for smaller spaces. Additional units can be combined for larger spaces. The product has no compressor, no refrigerant, is light, and can be installed simply by mounting it on a wall with the included mounting brackets and plugging it in. The claims are given below.

     The testers were concerned that the product is only available from the manufacturer, rather than from Amazon or eBay, but apparently, this is due to the proliferation of cheaper “knock-offs” with similar-sounding names like Cool Cave, which are likely inferior reverse-engineered copies.

     The product was tested in an attic apartment and in an attic home office, and it cooled down the space quickly. They also noted that the noise level is low, below 40 dB. Power consumption was recorded in the attic home office test.

“Power consumption over the 8 hours of operation, measured with a standard outlet energy meter: 0.38 kWh. At current electricity rates, that comes out to about 17¢ for a full workday. A comparable split-system AC running the same load would have used roughly ten times as much.”

     They also tested the product in a senior apartment, a kid’s bedroom, and in an RV, with similarly effective results.

     The unit is cheap, around a hundred bucks or less, and there is a 30-day money-back guarantee.

     How does it work?

“The answer comes down to the airflow geometry inside the unit. Unlike a traditional AC, which runs a compressor with chemical refrigerant looping between an indoor and outdoor unit, the CoolCove uses three sequential cooling chambers in which warm room air is progressively cooled.”

     I saw a video ad that noted that the inventor’s mother had suffered and maybe died from heat due to loss of AC that was the result of a massive electricity bill that she couldn’t pay. As a result, and since he was a cooling engineer, he was motivated to invent an effective AC system. That could, however, be an exaggerated marketing ploy.

     Perhaps it’s all a scam, and even the testing and the average 4.8 out of 5, 1400-plus positive reviews are part of the scam. I would not doubt that such elaborate scams occur. However, when I asked if it was a scam in a search engine, it came up with a Consumer’s Choice article that listed it as the number one portable air conditioner of the year with a 9.9 out of 10 rating. They did note, however, that it often runs out of stock. Of course, that is probably a good thing for something that likely works.

     However, I did come across a couple of articles that described it as basically an elaborate fan that could not replace a standard AC unit, even in a small space. One Snoops reviewer said that higher-priced fans could cool a room better. She also notes that the marketing ploys used suggest that the company is a bit shady.

     Thus, I would say the jury is still out on the product. I saw it as low as $89, with knock-offs as low as $25. A box fan costs about $20-25, and a better fan can cost about $69. Thus, the risk of simply getting an expensive but effective fan instead of an effective AC unit won’t break the bank. Since it is similar in cost to a high-end fan, the risk of feeling ripped off isn’t that great either, especially since it functions as a ceramic space heater as well. In any case, I don’t need one, but I would like to see for myself whether it works as advertised.  

     I did find a recent detailed review that considered all the pros and cons of the unit. The reviewer here said that as long as one understands that it is basically a unit for a single small room, one will be happy with the result. There are six modes. Wall mounting saves space. It also has a remote control.

“A few things point to legitimacy. It’s a coherent, real category of product, a compact plug-in AC and heater, not some impossible gadget that defies physics.”

     This reviewer also suggested that it beats out a fan. They also did not like some of the marketing. Below, they note some of the product's features. 400-800 watts is low for a heating or cooling device. I am guessing the cooling stays in the low range. A typical 20-inch box fan pulls about 50 watts on a low setting and about 75 watts on the high setting. Higher-end tower fans may pull 100 watts. Thus, at 400 watts (my assumption), the device should cool better than a tower fan.

“Against a plain fan, CoolCove is the clear upgrade once a room is already hot, because a fan just shoves warm air around, while this actually pushes out cooler air and can heat up too.”

     Another realistic reviewer noted that evaporator-cooling is a real thing:

"In cooling mode, the unit pulls warm room air in through its vents and moves it through what the company calls its internal evaporator cooling chamber, where the heat is drawn out of the air before the cooler air is pushed back into the room. The brand markets this as its RapidCool Airflow System, which is simply its name for the process rather than a new law of physics. The important takeaway is that evaporator-based cooling is a real, established way to lower the temperature of air, and because the moisture is managed inside the cabinet, there's no hose and no tank, which is what keeps the whole thing genuinely portable and wall-mountable."

     Thus, I would say that for $89, the value is likely pretty good or at least comparable to buying a high-end fan and a space heater. In this case, one can get both in one unit.
