Test Aecooly Cold Air Ultra: a powerful pocket fan with integrated cool mist

There are products that we first look at with a bit of a wry smile. A pocket fan capable of cooling the skin in a few seconds? With an integrated misting feature? A touch screen? And even an external battery function? On paper, the Aecooly Cold Air Ultra checks all the boxes of an overly enthusiastic summer gadget.

Except that during a heatwave, when the outside air resembles that coming from a slightly open oven, one quickly becomes less mocking. A classic fan often just moves hot air around. It provides some relief, but not much more. The Aecooly Cold Air Ultra adds a fine mist of water to the airflow; and it’s this detail that changes the game.

The brand speaks of a “personal cooling system,” in other words, a personal cooling system. The term is marketing, but the idea holds: this is not about cooling a room, nor replacing an air conditioner, but about directly cooling the skin. On a terrace, in line, in a parked car in the sun, at a campsite, while hiking, at a festival, or even at the office when the air conditioning has decided to go on holiday, this type of device quickly becomes essential.

The model tested here is the Aecooly Cold Air Ultra, sometimes referred to as Cold Air Pro or PM01S/PM02 depending on the market. The range is not always very clear, but the current official version highlighted by Aecooly is indeed the Cold Air Ultra with a 7000 mAh battery, airflow up to 25 m/s, color touch screen, misting, and fast USB-C charging.

Unboxing the Aecooly Cold Air Ultra

The Aecooly Cold Air Ultra comes in well-crafted packaging. It’s immediately clear that the brand wants to position itself above the small USB fan priced at €10 that can be found in stores from June onwards.

Inside: the fan, a USB-C cable, a strap, several magnetic tips, a small cleaning brush, a manual, and a small thermosensitive disk to quickly visualize the temperature.

The fan first surprises with its format. It remains portable, of course, but it’s not a lightweight mini fan that you slip into a jeans pocket without thinking.

At 345 g, with dimensions of 140.4 x 63 x 41 mm and an integrated water tank under the handle, it is more stocky, denser, almost “tool-like” in the hand. We are closer to a mini turbo blower than to a simple pocket fan.

The finish is quite good. The chassis is made of ABS and PC, with a surface that imitates metal quite well. At first glance, one might think it is constructed from aluminum – the finish is quite premium. In reality, it is plastic, but a rigid, well-fitted plastic that feels good in hand.

At the front, we find the turbine, protected by a grille. At the back, the intake grille can be removed without tools for cleaning. This is a good point, as powerful fans inevitably draw in dust over time. Aecooly has also provided a safety feature: if the back grille is removed, the fan does not start. Given the announced rotation speed, this is reassuring.

Under the device is the water tank.

It unlocks by turning a metal ring, then is filled with clean water. The brand emphasizes: no essential oils, no fragrances, no exotic liquids. Only clear water. It’s less fun for spa ambiance enthusiasts, but much more reasonable to preserve the pump and avoid clogging.

On the front, the color touch screen gives the product real personality. It displays the speed, battery status, misting function, water level, and operational animations. This is not essential, but it’s pleasant and readable – frankly more rewarding than a simple LED indicator.

Technical Specifications

The Aecooly Cold Air Ultra has a strong technical sheet for such a compact device. The brand announces a turbine at 70,000 rev/min, a maximum airflow speed of 25 m/s, a 7000 mAh battery, fast USB-C charging, and a battery life that can reach 10 hours at low speed with 100 levels of ventilation.

The fan also has a reverse charging function. In plain terms, it can serve as an external battery to help charge a smartphone or another small USB-C device. This is not its primary purpose, but while on the go, it’s always handy. When heading out with a water bottle, sunglasses, phone, keys, camera, and three cables that tangle like spaghetti, every less object in the bag is a victory.

The full charge takes about 2 hours and 30 minutes. The charging power hovers around 20 W, which is fast for this type of product.

On the noise front, Aecooly announces up to 65 dB at low speed. Let’s be direct: this fan is not silent. It blows hard, very hard even, and you can hear it. At low speed, it remains bearable outdoors. At full power, it produces a high-pitched turbine sound, quite similar to a mini hairdryer or a compact blower. No miracles: when you want 25 m/s in the palm of your hand, you have to accept that it’s noisy.

Installation and Handling

The handling is straightforward. A long press on the main button turns on the fan. It generally starts at an intermediate level, and the speed adjusts in two ways. The physical button allows rapid transitions through levels: 20, 40, 60, 80, and 100%. The touch screen allows for finer adjustments, level by level, up to 100.

The screen is responsive and pleasant to use. You can swipe to increase or decrease the power, similar to some high-end “turbo” fans. After a few seconds, the screen locks to prevent accidental changes. You then need to wake it up, usually by double-tapping or pressing the button. It’s well thought out, as the hand easily falls on the touch area.

The misting feature is controlled with a side button. A sustained press triggers the water projection as long as the button is held down. A double tap allows for continuous misting for 30 seconds. The idea is not to spray your face like a green plant but to deposit a very fine layer of moisture on the skin, and then let the airflow do its work.

Filling the tank requires a bit of attention. You need to open the bottom, pour water up to the maximum mark, and then close it properly. The seal must be correctly positioned to avoid leaks. It’s better not to fill it to the brim, especially if the device moves in a bag or is used in various positions. Leaving a small air space avoids unpleasant surprises.

A Real Difference Compared to a Classic Fan

The Aecooly Cold Air Ultra stands out not only for its power. Very powerful turbo fans already exist. The real interest comes primarily from the combination of airflow and misting.

A classic fan accelerates the evaporation of sweat. When the air is still breathable, it is often enough to give a feeling of coolness. But when it’s 35, 38, or 40 °C, the air moved is already hot. The fan provides relief, but sometimes it ends up feeling like blowing with a hairdryer.

With the misting feature, the principle changes. The device projects very fine water droplets that settle on the skin or almost immediately evaporate in the airflow. This evaporation consumes heat, thus cooling the skin more quickly. It’s the same phenomenon as the feeling of cold after a swim when the wind picks up. Except here, everything fits in your hand.

In optimal conditions, the surface temperature measured with a thermal camera drops several degrees in just a few seconds. One of my tests, for example, went from around 31.5 °C on the skin to 30 °C with just ventilation, and then around 24-25 °C with ventilation and misting. Quite effective!

On the face, forearms, or neck, the sensation is immediate. The first jet of mist combined with the powerful airflow really gives the impression of standing in front of an air conditioning vent. Not for long, not over the entire body, but enough to break the heat peak.

Misting: Effective, But to Be Used Smartly

The mist generated by the Aecooly Cold Air Ultra is fine. It’s not like a garden sprayer. You won’t get soaked after two seconds, and that’s a good thing! On the arms or neck, it dries very quickly with the airflow. On the face, it all depends on the distance, duration, and any makeup involved.

For comfortable use, it’s better to proceed with small bursts. A brief spray on the skin, then a few seconds of ventilation. There’s no need to keep the misting continuous for a minute. A fine layer of water evaporates better and cools more than a wet skin. It’s counterintuitive, but it works.

The tank is not huge. With continuous use, you get about 10 minutes of misting from a full tank. That may seem short. But in real use, you don’t typically use the mist continuously. A few regular sprays are more than enough to cool off during an outing. For hiking, a festival, or a full day outside, you just need to remember to refill from time to time.

Also, pay attention to sensitive items. Non-waterproof headphones, a mechanical watch, smart glasses, a camera, a smartphone that’s already warm but not necessarily protected… The mist is fine, but it’s still water. It’s better to avoid misting directly anything that dislikes humidity.

Another practical point: cold or icy water doesn’t necessarily provide a huge benefit. Multiple tests show that the effect mainly comes from evaporation, not from the initial temperature of the water. Clean water at room temperature will suffice.

A Really Powerful Breeze

Even without misting, the Aecooly Cold Air Ultra blows strongly. Very strongly. The announced maximum speed of 25 m/s is not just a marketing claim: independent measurements approach 24-25 m/s, which is impressive for a device of this size.

At low speed, the airflow is already strong. At full power, it enters the realm of mini blowers: hair flies back, dust lifts off a keyboard, and light objects have to hold on tight. Between the two, it’s easy to find a comfortable setting to cool off outside.

With the provided magnetic tips, the Aecooly can concentrate the air to dust off a keyboard, a camera lens, a car dashboard corner, a ventilation grille, or even revive a campfire.

The small brush tip combines blowing and mechanical cleaning. You won’t replace a dedicated electric blower, but for a handheld device, it’s versatile. It prevents you from having a device stored in the cupboard for 10 months of the year: apart from heatwaves, it will help with cleaning.

The trade-off for this power is that the airflow is concentrated. At a close distance, especially at high speeds, it can become too aggressive on the face. The right setting often falls between 40 and 70%, with occasional misting. To be honest, I usually use it at only 10%. At 100%, it’s spectacular but rarely useful for more than a few seconds.

Noise: The Price of Power

This is the point that will cause the most division. The Aecooly Cold Air Ultra is not discreet. Even at low power, its high-speed motor produces a high-pitched noise: not a “soft breeze,” but rather a turbine sound.

Outdoors, by a pool, in a garden, while camping, at a rest stop, or in a busy street, it’s acceptable. The ambient noise masks a good portion of the sound. In a quiet office, a silent train, or a waiting room, you’ll have to keep it at low speed – or even not use it if you care about your neighbors.

Battery Life and Recharge

The 7000 mAh battery offers great endurance, provided you don’t run it continuously at 100%. Aecooly announces up to 10 hours at low speed. This is reasonable for moderate use, without permanent misting. At high power, the battery life inevitably decreases – the motor consumes much more.

In realistic use, with sessions of a few minutes, adjustments around 40-70%, and misting activated at times, the Aecooly easily lasts a full day’s outing. For a commute to work, a stroll in the city, an afternoon in the garden, or a photo session in full sun, there is plenty of capability.

At the office, I use it without problem all day long, simply placed on my desk, at barely 10%, and with occasional misting, which is quite pleasant. And it still has plenty of battery left by the evening.

The fast USB-C charging is a true comfort. With a compatible charger, it takes about 2 hours and 30 minutes to return to full battery. The screen displays the charge level, preventing any nasty surprises.

The external battery function is handy, but it’s not a reason to buy it. The Aecooly can charge a smartphone in an emergency, the screen shows a dedicated animation, and it’s nice to have the option in your bag. But with 7000 mAh, it won’t replace a real travel power bank. It’s an emergency wheel, not a new tire.

Maintenance and Precautions

A misting fan requires a bit more maintenance than a classic fan. Nothing too complicated, but you shouldn’t store it full of water for three weeks in a drawer.

After use, it’s better to empty the tank, especially if the device won’t be reused quickly. This avoids deposits, odors, and bacterial growth. It’s also better to use clean water, or even filtered if the tap water is very hard. The misting circuit is fine, and scale is never a very loyal friend.

Aecooly provides a cleaning procedure for the circuit: by blocking the nozzle and activating the misting, the air can flow in the reverse direction to clear impurities. It’s clever, and it shows that the brand has considered real-world use.

The removable back grille also makes it easier to clean the turbine. A small brush is included, and it’s not a gimmicky accessory. After a few weeks in a bag, among dust, textile fibers, and leftover crumbs at the bottom, it will come in handy.

Finally, be cautious with the USB-C port. The product handles water, but the charging port remains exposed. We would have liked a rubber cover to better protect it: on a product that mist, a minimum of physical protection around the USB-C would have been welcome.

In Everyday Life: Who Is the Aecooly Cold Air Ultra Really For?

The Aecooly Cold Air Ultra is not the ideal fan for everyone. If you’re looking for a small, quiet fan to place on a desk, there are more suitable, lighter, cheaper, and less noisy models available. If you just want a gentle breeze while commuting, a classic model will suffice.

However, if you really suffer from the heat, if you spend time outdoors, if you go camping, hiking, or doing outdoor photography or video, attending fairs, markets, festivals, or if you work in poorly air-conditioned places, the Aecooly makes total sense.

It is also interesting for occasionally cooling certain devices. A smartphone that overheats while filming in 4K in the sun, an exposed camera, a portable console, or a mini PC used outdoors can benefit from the airflow and, with caution, from misting at a distance. Be careful not to spray water directly into a port or ventilation grille.

For home use, it also helps in concrete situations: during DIY work in a garage, in a conservatory, in an attic bedroom, in the vegetable garden, near the barbecue, or when mowing/trimming/watering in the middle of a heatwave. It’s the kind of item that seems a bit excessive at first but is eventually grabbed instinctively before heading out.

Limitations to Be Aware Of

345 g is not heavy, but for a device held out at arm’s length for a long time, you feel it. The strap is useful, and it’s better to alternate hands or use it in short sessions.

The noise, on the other hand, does not go unnoticed. The power is excellent, but it comes with a sound price. Outdoors, it’s fine. In a calm indoors setting, less so.

The tank is sufficient for occasional use, but heavy users will need to refill it regularly. A version with a larger tank or an additional storage accessory would be welcome.

Regarding water: even though the mist is fine, you’re handling an electronic device with an integrated tank. Make sure to properly close the cap, not overfill it, avoid wetting the USB-C port, and empty the tank after use.

Finally, the price. The Cold Air Ultra is listed at $79.99 on the official website. Here, you pay for the turbine, the battery, misting, the screen, accessories, and the power bank function. For a simple airflow device, it’s too much. For serious anti-heat use on the go, it defends itself. Especially since competitors like Dyson, Ninja, etc., who have also launched in this segment are often much pricier, sometimes double the price of this Aecooly.

Conclusion

The Aecooly Cold Air Ultra is not just a simple pocket fan with an additional gadget. Its misting really changes the experience. When it’s very hot, a fine layer of water in the airflow cools the skin much faster than a classic fan. The effect is immediate, sometimes surprising, and frankly pleasant.

It’s not perfect. It’s quite noisy, heavier than a basic model, its tank could be more generous, and a cover for the USB-C port would have been a good idea. But it does what it is asked to do: provide real cooling. And in the middle of a heat wave, that’s what counts.

It’s designed to provide a direct cool feel where you need it, not to cool a room. It’s not the same use – and in its own, it is quite convincing. Personally, this test came just in time to better withstand these two heatwaves that have already hit us this year :p

The Aecooly Cold Air Ultra is available for $79 on the manufacturer’s website.
