How does this handheld fan with a cooling function redefine summer coolness? — A real-world review

On a 40°C subway commute, ordinary fans blow hot air. On hikes, handheld devices die after half an hour. These pain points have finally been solved with this fan. It not only offers 100 precise wind speeds but also a one-touch 16°C cooling mode. Its 3000mAh battery lasts for 12 hours outdoors, and its 243g weight easily fits into a backpack. Most impressively, the speed adjustment is as smooth as adjusting the volume. If you're tired of fans that "get hotter the more they blow," this review will explain why it's a must-have for your summer.

100 Speed Levels + Pulley Adjustment: Precisely "Cools My Milk Tea Without Messing My Bangs"

I've always struggled with the three-speed adjustment of regular fans, but this model's 100-speed + pulley design completely changes the experience:

Pulley Operation: Simply slide your index finger to adjust the speed, seamlessly switching from level 1 (a gentle breeze) to level 100 (strong wind). This is three times faster than adjusting with buttons, making it easy to operate blindly on a crowded subway.

Scene Compatibility: Levels 1-30 are perfect for studying in the library (the wind speed is as gentle as turning pages), 50-70 for an office lunch break (without disturbing colleagues), and 80-100 for outdoor heat (9m/s direct cooling).

In actual testing, I used level 45 at a coffee shop, which was just enough to cool the steam on the surface of my latte without blowing away any water droplets on the cup's walls. The precision was amazing.

16°C Cooling: More than just air, it's a "pocket air conditioner"

The moment you activate the cooling function, the fan head becomes instantly chilled—this is the fundamental difference between this fan and ordinary fans:

Tested results: At 38°C outdoors, cooling combined with 80 wind speeds reduced the perceived temperature by 8°C, feeling like a freshly-frozen towel on the skin.
Dual Cooling: The ice-ceramic cooling device combined with a high-speed fan delivers 40°C hot air in and 16°C cool air out. Blowing it onto your neck for 3 seconds after exercise instantly eliminates the sweaty feeling.
Balanced battery life: Even with cooling enabled, it can still run for 6-8 hours, 2 hours longer than similar cooling fans, enough for a full day of play.

3000mAh Battery + 2-Hour Fast Charge: 12 Hours of Cooling Without a Break

Battery life and charging speed are paramount for outdoor enthusiasts, and this model far exceeds expectations:

• 12-Hour Battery Life: I spent my daily walks from 8 AM to 8 PM with 15% battery remaining.
• Emergency Fast Charge: 20 minutes of charging with a power bank at breakfast gives me 3 hours of moderate wind speed, perfect for recharging before catching a high-speed train.
• Type-C Universal Port: Compatible with mobile phone charging cables, so you only need to bring one cable when traveling, no need for a separate charger.

No more worrying about a sudden loss of power from your fan. This is what a portable device should be.

243g Lightweight Design: A "Portable Cooler" That Stays Tired of Holding for Long Periods

At 243g, it's lighter than a 330ml can of Coke, making handheld use a real pleasure:

• Commuting Test: I held it one-handed on the subway for an hour without any arm strain, while my previous fan felt like putting it down after just 10 minutes.
• Easy Storage: It fits effortlessly into the back pocket of jeans or the side pocket of a canvas bag, allowing you to grab and go while shopping without having to set aside a separate space.
• Non-Slip Sense: The rounded body fits snugly in your palm, preventing slippage even when sweating, and provides a super stable grip when hiking.

For women or those with weaker hands, "lightness" isn't just a plus; it's a prerequisite for carrying it daily.

LED Digital Display: Clearly view fan speed and battery level at a glance

Although the screen is small, it packs a punch, eliminating guesswork:

• Real-time displays indicate the current setting (e.g., "68") and remaining battery level (e.g., "72%)," ensuring accurate fan adjustments.
• When cooling mode is on, a snowflake icon illuminates, distinguishing between normal and cooling airflow at a glance.
• Automatically brightens in bright sunlight and dims on cloudy days, ensuring smooth nighttime use. These thoughtful details are incredibly detailed.

No more embarrassing moments of "thinking there's still power, only to have it shut down mid-flight," giving you a supreme sense of security.

Low-Noise Operation: An "Invisible Fan" that's also safe for use in libraries.

Worried about fan noise? A measured noise level of under 45dB gives you peace of mind:

• At the office, at setting 50, a colleague on the phone was completely oblivious to the fan being on.
• At the library, at setting 30, the sound of flipping pages was even louder than the fan, and the administrator walked by without a word.
• At night, at setting 40, the wind blends in with the chirping of insects outside the tent, ensuring a pleasant sleep

This is more important than wind speed for students or those who need a quiet environment.

Multi-Scenario Test: An "All-Rounder" from Commuting to Camping

After using it for a month, I found it incredibly useful in these scenarios:

• Commuters: Using the Cooling + 60 setting in the subway instantly eliminates the stuffiness from masks, and my makeup stays put even after I take it off.
• Gym Enthusiasts: Using the Cooling + 100 setting after a workout to blow away sweat is more hygienic than the big fans at the gym, and it also effectively blows down my back.
• Campers: Hanging it on a tent pole, using the Cooling + 50 setting, the temperature inside the tent is 5°C lower than outside, eliminating the need for stuffiness in my sleeping bag.
• Moms: Using the Cooling + 30 setting when changing my baby's diaper doesn't blow directly, but it does disperse odors and is 10 times more labor-efficient than a hand-cranked fan.

Why is it a worthwhile replacement for your old fan?

After comparing eight handheld fans, this one's advantages are clear:
It offers 16°C more cooling than regular handheld fans, a true "dimensional reduction strike" in the heatwave;
The slider adjustment and LED screen make it far superior to push-button controls;
With a 2-hour fast charge and 12-hour battery life, it addresses the biggest pain points of portable devices.
If you're looking for a summer gadget you won't leave unused, this is the most cost-effective option.

Verdict: This is the most "unexpected" cooling tool of the year.

From crowded rush-hour subways to scorching campsites, from stuffy gyms to quiet libraries, this handheld fan, with its 100 precise speed settings, 16°C cooling technology, and long battery life, proves that "good cooling equipment can make summer comfortable." It's more than just a fan; it's a pocket-sized "air conditioner."

If you're tired of sweaty summers, give it a try—you might, like me, become obsessed with that 16°C coolness.
