A portable misting fan with some serious cooling power.

\n\n\n\n

Handheld fans are everywhere these days, but most of them feel pretty basic with a single speed and a battery that dies before your iced coffee does. The Aecooly Cold Air Ultra is a different beast. It’s a powerful high-speed fan with a built-in misting system, sleek design and intuitive touchscreen. After testing it for a few weeks, I’m very impressed with this little machine.

\n\n\n\n

What’s in the box

\n\n\n\n

Aecooly includes a decent set of accessories in the box. Along with the handheld fan itself, you get a wrist strap, a USB-A to USB-C charging cable, a cleaning brush, a Fahrenheit/Celsius reference sticker, the usual paperwork, and a couple of nozzle attachments.

Those magnetic attachments are the most useful items of the bunch: a pointed nozzle and a round nozzle, plus a small brush head that connects to the round nozzle. Pop them on and the Cold Air Ultra doubles as a handy air duster, useful for blasting dust out of keyboards, vents, desks, your car, or anywhere else a can of compressed air would normally do the job.

\n\n\n\n
\n\n\n\n

Design & build quality

\n\n\n\n

This is where the Cold Air Ultra immediately sets itself apart from the sea of generic handheld fans out there. The design is sharp and sleek, with a matte finish and clean lines that feel much nicer than you might expect from something designed to blast air at your face. Build quality is also excellent throughout, and the device has a nice weight to it that makes it feel premium.

\n\n\n\n
\n\n\n\n

That solid build could also be seen as a small trade-off though: at 349g (0.77lb), it’s certainly not the lightest fan in this category. You’ll notice it in your hand or your bag more than a lightweight alternative. But it’s genuinely compact for what it packs in, and the size-to-performance ratio is one of its strongest points. This isn’t a fan you’ll forget you’re carrying, but it’s also not a fan you’ll mind carrying.

\n\n\n\n

The water tank for the misting function sits at the bottom of the unit and holds a small amount of water. To refill it, you flip the fan upside down and open a lid secured by a small pull-ring lock. It’s a simple mechanism, but it’s very secure, so there’s no risk of the lid popping open in your bag.

\n\n\n\n
\n\n\n\n

The touchscreen is one of the nicest surprises here. It’s clear, well laid out, and displays fan speed, water level and battery level at a glance. There’s also an animated water droplet character that pops up on the screen and changes expression depending on what’s happening.

This little guy gets its own short greeting animation when you power the unit on, squints and spits out a little spray when the misting function is active, looks happy at high battery levels, then tired and droopy around 20%, and flashes an urgent red warning when the battery gets critically low. It’s a small thing, but it adds a nice amount of personality to what’s usually a purely functional readout.

Cooling & misting performance

\n\n\n\n

The Cold Air Ultra works two ways: as a straightforward high-speed fan, or as a misting cooling fan that adds a fine water spray into the airflow. Both modes work extremely well. As a standalone fan, the airflow is strong and immediate, with Aecooly quoting a 70,000RPM maximum motor speed and wind speed of up to 25m/s (82 ft/s). That is a serious amount of air being pushed for something this small.

\n\n\n\n

But the misting mode is the real trick here. With it on, you get a genuinely different experience, with the kind of instant, noticeable cooling that a regular fan just can’t replicate on a properly hot day. The spray can be activated either by pressing and holding the side button that sits just below the USB-C port, or with a quick double-press if you’d rather not hold it down. Either way, it’s not something you’ll trigger by accident.

\n\n\n\n
\n\n\n\n

According to the brand, this micro-mist can reduce surface temperature by up to 18°F (10°C) in just 10 seconds. I didn’t have a thermal camera on hand to verify those exact numbers, but it sure does feel like it’s true.

That fan and mist combo is perfect for outdoor events (I wish I had one earlier this year at the Australian Open), backyard BBQs, summer travel, or even just walking the dog on a hot afternoon. I recently got an English Bulldog puppy, and since the breed is notoriously bad at dealing with heat, this is exactly the kind of thing I’ll be keeping close by to help him cool off when the weather gets uncomfortable.

\n\n\n\n

\n\n\n\n

Fan speed can be easily controlled by pressing the power button to cycle through preset increments of 20, which is fast and convenient for quick adjustments. If you want finer control, you can swipe up and down on the touchscreen to dial in a more precise speed rather than jumping between presets. That touchscreen slider is disabled automatically after 3 seconds of inactivity, which I’m assuming is an intentional choice to prevent accidental touches while holding the fan once you set your preferred speed. You can quickly reactivate it again with a simple tap of the power button.

Noise level

\n\n\n\n

All that power and cooling performance comes with a compromise, which is the noise level. At lower speeds the device is relatively quiet and unobtrusive, but push it toward the top of its 100 speed levels and the motor gets properly loud, like a little jet engine. It’s powerful enough that you will no doubt get a few curious looks if you’re running it at full blast in public.

\n\n\n\n

That said, on a truly hot day, I would argue that the trade-off is easily worth it. I’d take a bit of noise over sweating profusely through my shirt every time.

\n\n\n\n

Battery life

\n\n\n\n

Battery life is quite good. For this review, Aecooly sent me the base model (Ultra B) with a 6000mAh battery that lasts up to 8.5 hours of use on low speed, which comfortably covers a full day out. If you want a bit more juice, you can go for the higher end Ultra with a 7000mAh battery, which is rated for 10 hours.

\n\n\n\n

Charging is quick too, a full top-up takes about 2.5 hours over USB-C, so it’s easy to top it back up at the end of the day. One nice touch I found buried in the manual: once the battery drops below 10%, fan speed automatically caps at level 50 (of 100) to help protect battery health.

Quick answers

\n\n\n\n

What are the modes available for the Aecooly Cold Air Ultra portable fan?

\n\n\n\n

The Cold Air Ultra works as a regular high-speed fan or a misting cooling fan. The mist function is activated separately, either with a press-and-hold or a quick double-press of the side button, so you can use either mode independently.

\n\n\n\n

How long does the Aecooly Cold Air Ultra battery last?

\n\n\n\n

It depends on the version. The Ultra B tested here is rated for up to 8.5 hours of use at low speed on its 6000mAh battery. The standard Cold Air Ultra uses a larger 7000mAh battery for up to 10 hours. Both charge fully over USB-C in about 2.5 hours.

\n\n\n\n

Is the Aecooly Cold Air Ultra loud?

\n\n\n\n

At low speeds it’s relatively quiet, but it gets noticeably loud at higher speeds due to its powerful 70,000 RPM motor. The ≤65dB figure quoted by Aecooly only applies to the lowest speed setting rather than peak volume.

\n\n\n\n

How much does the Aecooly Cold Air Ultra weigh?

\n\n\n\n

The Ultra B tested here weighs 349g (12.3oz), which is on the heavier side for a handheld fan but still compact enough to carry comfortably in a bag. On the flip side, that solid build makes it feel like a premium product.

\n\n\n\n

How do you adjust the fan speed on the Cold Air Ultra?

\n\n\n\n

You can press the power button to cycle through preset speed jumps of 20, or swipe up and down on the touchscreen for finer, more precise speed control across its 100 levels.

Verdict

\n\n\n\n

The Aecooly Cold Air Ultra feels more like a piece of high-end consumer tech than a novelty summer gadget. It looks and feels premium, the misting function is incredibly effective on a hot day, and the touchscreen with its animated character adds a level of polish and personality that most competitors skip entirely. The extra weight and higher-speed noise are minor trade-offs against how effective this device is at its actual job: cooling you down fast, when it matters.

\n\n\n\n

The Aecooly Cold Air Ultra B, as tested here, is available now at Aecooly’s website for $59.99. If you want the extra battery life, you can get the standard Cold Air Ultra with a larger 7000mAh battery for $79.99.
