We Bought & Tested the Best-Selling Portable ACs, Here's Why Ultra Air Cooler is #1:
Summary: In testing we found that Ultra Air Cooler will super effectively cool your personal space in less than 5 minutes. It’s fully portable, light weight and saves you hundreds of dollars by opting for this instead of your regular AC. Ultra Air Cooler
For the past few years, 3 large corporations have basically had a monopoly on the AC industry. This has resulted in massively increased prices ripping customers off. The big companies could set whatever prices they wanted to as there was no competition. Until now.
A small startup with almost no funding is disrupting this $135b industry very quickly.
Originating in Silicon Valley, the startup called Ultra Air Cooler has figured out a new way of cooling the air quickly at a fraction of the cost. And it’s so simple it can be built into a tiny, portable device.
Weather services are forecasting an extremely hot summer in 2025, so the Ultra Air Cooler couldn’t have arrived at a better time. In fact, the sale of their new AC is going like crazy already and the summer hasn’t even started yet.
Exactly what is a Portable AC?
The Ultra Air Cooler is a simple, yet very clever device.
In short it’s a fully portable, light weight air cooler that can cool down any space in 5 minutes. All you need to do is plug the cable, and pour some water in the tank. That’s it.
The best part about it is that thanks to their new technology, it only uses a fraction of the power compared to a traditional AC, or even a regular fan. This results in massive savings on your electricity bill during those hot summer months.
The goal of the founders of Ultra Air Cooler was to make an affordable, effective way to stay cool without wasting money. After using it for a few weeks now - I can safely say they succeeded.
So, what can Ultra Air Cooler actually do? Everything your regular AC can do -- And more. Compared to a traditional AC - it's cheaper and easy to carry over to the space you need it most
But what makes the Ultra Air Cooler a real game changer is it’s compact design and long battery life. Sure, regular AC units are great but they only cover the room they are installed in.
With the Ultra Air Cooler , you can bring it wherever you go -- even to the office or on a camping trip.
No installation or maintenance costs, all you need is some tap water and the USB charging cable.
This is the next generation of AC units.
How Does It Work?
Ultra Air Cooler uses the latest Rapid Cooling System that uses water to micro-freeze the air flow into it, then pumps out perfect cold air on the other side.
It's super easy to set up. Just fill the 550ml (1 normal drinking glass) water tank and press the power button. If you run out of battery (8 hours of battery life) then simply plug the USB cable in. Charge it in any USB port - even your laptop could power it.
It's very small compared to other portable ACs. This makes it very easy to carry around with you. The Ultra Air Cooler system uses the water in the tank very efficiently, with 1 full tank lasting you the whole day.
The fan is very strong and doesn’t make any noise at all. All other Portable Mini AC Fans we’ve tested make a lot of noise, making it annoying to have on while you sleep.
The Ultra Air Cooler has 4 modes:
- Low Mode - It’s like a desktop fan, but cold
- Medium Mode - This is great for smaller rooms that get hot
- High Mode - If you need to cool down any size room super fast
- Turbo Mode - If you need to cool down any size room in fastest mode
In our testing, we decreased the temperature of a medium sized room by up to 18°F within a matter of minutes.
But the Ultra Air Cooler does a lot more than just making the air cool. It also filters the air around it, clearing our dust particles and allergens. If you live in a dry, dusty place you will love this!
The best part about it is how silent it is. You can barely hear the fan, even on the max setting. This was the main feature that made us rank this #1 in our testing.
What Exactly Can The Ultra Air Cooler Do?

and that's not it!
Pollen, dust, and who knows what else is all floating around in the indoor air. And the indoor pollution only gets worse when you’re inside all the time. Even particles from your clothes and hair get into the air.
The Mini AC Fan has a Filter to help trap all these particles before they get blown on you.
