With electricity costs constantly on my mind, I started looking for alternatives to running the air conditioner all day. That’s what led me to the COSTWAY Portable Evaporative Air Cooler.
The ads made it sound like a compact, energy-saving solution that could keep an entire room comfortably cool. I thought I had found a cheaper alternative to traditional air conditioning.
After using it, I realised I had misunderstood what this product actually is.
What is the COSTWAY Portable Evaporative Air Cooler?
The COSTWAY Portable Evaporative Air Cooler is a 3-in-1 appliance that works as a fan, humidifier, and evaporative cooler. Instead of using a compressor like a real air conditioner, it cools air by passing it through water-soaked cooling pads and can use ice packs for additional cooling. It works best in hot, dry environments with humidity below 50%.
Why I Tried It
I wanted something that would lower my electricity bill while still making the room feel cooler.
The portability appealed to me, and I liked the fact that it didn’t require exhaust hoses or complicated installation. Moving it from the bedroom to the living room sounded much easier than dealing with a traditional portable AC.
My Experience Using It
Setting it up was easy. Fill the tank, add the included ice packs, plug it in, and you’re basically ready to go. The first thing I noticed was that it definitely moves a lot of air. As a fan, I actually liked it. Sitting directly in front of it felt refreshing.
But the longer I used it, the more I realised this wasn’t really replacing my air conditioner. It simply wasn’t producing the kind of cooling I had expected.
The air coming out felt slightly cooler than a regular fan, especially immediately after adding ice packs, but the difference wasn’t dramatic. After a while, it mostly felt like a powerful fan with a little extra moisture in the air.
And that’s where climate matters. On drier days, the cooler performed reasonably well. On humid days, I almost felt like it was making the room feel heavier rather than cooler. Once I learned how evaporative coolers actually work, that made perfect sense.
I also found myself refilling the water tank more often than I expected. Eventually, I stopped thinking of it as an air conditioner and started treating it like an upgraded fan. Once I adjusted my expectations, I appreciated it much more.
Build Quality & Feel
The unit feels lightweight and easy to move thanks to the wheels. Most versions include remote controls, multiple fan speeds, and oscillation features.
It doesn’t feel premium, but it doesn’t feel cheap either.
Pros & Cons
Pros
- Uses less electricity than an AC
- Easy to move around
- No complicated installation
- Works well as a fan
- Ice packs provide extra cooling
- Multiple speed settings
Cons
- Not a substitute for real air conditioning
- Performance depends heavily on humidity
- Requires regular refilling
- Cooling effect is fairly modest
- Can make humid rooms feel worse
- Expectations can easily exceed reality
Product Claims vs. Reality
This is where I think many buyers get disappointed. The cooler does exactly what evaporative coolers are designed to do.
The problem is that many people, including me initially, expect it to perform like a real air conditioner.
It doesn’t. It works best in dry climates and provides localised cooling rather than dramatically lowering room temperature. COSTWAY itself states that these units perform best in environments with humidity below 50%.
Is It a Scam?
No. The machine functions exactly as an evaporative cooler should.
I think the biggest issue is that the phrase “air cooler” can make buyers assume they’re getting air-conditioner-level performance when they’re really buying something much closer to a fan with added cooling assistance.
Customer Review of the COSTWAY Air Cooler
Customer feedback tends to mirror my experience.
People living in dry climates often seem much happier with these coolers, while users in humid regions frequently report disappointing results. That matched what I experienced almost perfectly.
How to Use
I got the best results by using it close to where I was sitting rather than expecting it to cool an entire room. Adding fresh ice packs also helped noticeably.
Most importantly, understanding that it’s an evaporative cooler, not an AC, made a huge difference.
Alternatives to Consider

Conclusion — Would I Recommend It?
Yes, but only to the right person. If you’re expecting air-conditioner performance, you’re probably going to be disappointed, like I initially was.
If you live in a dry climate and simply want a stronger, more refreshing fan that uses less electricity, then the COSTWAY Portable Evaporative Air Cooler makes much more sense.
My biggest mistake wasn’t buying it. It was expecting it to be something it was never designed to be.
