This transparent handheld fan: cool and long-lasting a stylish and powerful summer cooler

Commuting in a 40°C subway, ordinary fans blow "hot air"; sweating profusely after a workout, handheld devices die in half an hour; wanting to work in a cafe, but worried the fan's appearance will degrade the quality of your photos—these summer pain points have finally been solved by a handheld fan. It not only offers 3-second ice-cooling technology, but also precise temperature control with 100 speed settings, a 3000mAh battery that lasts for 7 hours outdoors, and a weight of 250g that easily slips into a jeans pocket. The transparent mechanical design also makes it a stylish addition. If you're looking for a cooling device that's "cool enough, lasts long enough, and looks good," this real-world review will tell you why it's worth buying.

3-Second Cooling Design: More Than Just Cooling, a "Real Cooling" Experience

The most revolutionary feature is its cooling function—press the snowflake button, and the fan head becomes icy cold in 3 seconds, delivering a noticeably cool breeze that's simply unattainable with standard handheld fans.

• Post-workout test: After a 5km run, I still felt hot after 5 minutes with a regular fan. Using this fan at Cooling + 50°F (likely a typo), the sweat on the back of my neck subsided within 1 minute, and my body temperature seemed to drop by 3°C.
• Commuting lifesaver: On a crowded subway, using Cooling + 30°F (likely a typo) instantly dissipated the stuffiness inside my mask, allowing me to keep my makeup intact when I took it off.
• Thin details: In Cooling mode, the fan head remains frost-free and drip-free, so you don't have to worry about getting a light-colored T-shirt wet. Perfect for summer use.

100 Stepless Speeds: From "a gentle breeze turning pages" to "strong wind cooling" for precise control

The 100-speed adjustment sounds complex, but it's actually addictive—no longer having to compromise between "not cool enough" and "too noisy":

Levels 1-30: Gentle breeze: When working on a report in the library, the wind is so gentle it's almost like turning pages, and my neighbor won't even notice I've turned on the fan.
Levels 40-70: Comfortable wind: During lunch breaks in the office, the wind just covers your desk, keeping your keyboard sweat-free and your video conference partner inaudible.
Levels 80-100: Hiking in 35°C temperatures, the 6m/s wind speed directly dissipates body heat, drying sweat stains on your T-shirt in half an hour.

Press and hold the "+/-" button to quickly switch between speeds, making it easy to operate blindly on a crowded subway. The adjustment efficiency is far superior to push-button fans.

3000mAh Battery Life: 7 hours of cool, non-stop power from morning to night

The 3000mAh battery's longevity completely eliminates the anxiety of finding an outlet to charge. Tests showed the following performance in different scenarios:
 

Daily Commuting: Leaving home at 8 AM and returning home at 6 PM with 15% battery left;
Outdoor Hiking: Walking from 10 AM to 3 PM without recharging, enough for a half-hike;
Emergency Charging: 1 hour of charging with a power bank provides 2 hours of refrigerated power and 50 speeds, allowing for quick recharging at the airport during layovers.
 

For those on the go, the peace of mind of not having to recharge frequently is crucial.

250g Lightweight: "Burdenless" Cooling in Your Pocket

At 250g, it's about the same weight as an iPhone Pro, making it a pleasure to carry around:

• Handheld Experience: I could hold it one-handed for an hour while shopping at the supermarket, and my arm felt completely pain-free. It's much easier to use than the 300g fan I used before.
• Easy Storage: Folds and slips into the back pocket of jeans or the side pocket of a canvas bag. At just 5.5cm thick, it takes up very little space and is super easy to access during security checks.
• Neck Compatibility: With the included silicone lanyard, you can wear it around your neck while running or camping, ensuring constant airflow and hands-free operation.

For women or those with weak 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

A small screen hides a wealth of features, eliminating the awkward guesswork of standard fan settings:

• Real-time Display: The current power level (e.g., "42") is displayed by default upon power on. Double-clicking the power button toggles the battery percentage (e.g., "68%)," allowing you to adjust the fan speed with confidence.
• Low Battery Alert: The screen automatically flashes when the battery drops below 20%, preventing sudden shutdowns and allowing you to recharge before catching the subway.
• Light Adaptation: The screen automatically brightens in sunlight and dims to a gentler setting at night, ensuring it won't disrupt your sleep even when placed by your bed.

Quiet Operation + USB-C Fast Charging: "Easy Design" in the Details

Beyond its core functionality, these details make it even more suitable for everyday use:
Quiet Performance: Equipped with a noise-canceling motor, even at 80% fan speed, noise remains below 35dB (quieter than a soft conversation), making it perfectly suitable for use in libraries and offices.
USB-C Fast Charging: Fully charged in 4-4.5 hours. Plug it into your dressing table while you put on your makeup in the morning and it's fully charged before you leave the house. Compatible with power banks and computer USB ports, you only need to bring one cable when traveling.
Last time, I was working in a cafe, using the fan at 30% fan speed and cooling my phone. My neighbor asked me, "Why is your fan so quiet?"

Transparent Mechanical Design: A Win-Win for Aesthetics and Practicality
 

The transparent body is a bonus, breaking the stereotype that practical tools must be ugly.
Visual Quality: The transparent exterior reveals the internal motor and fan blades, creating a high-tech, mechanical design that looks more upscale on your desk than ordinary plastic fans.
Versatile Colors: The black version goes well with sportswear, the white with dresses, and the purple with casual wear. The fan can even be used as a prop for photos, often mistaking it for a new accessory.
Easy to Clean: The transparent material resists stains; fingerprints come off easily with a wipe, making it much easier to maintain than a matte exterior.

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

After using it for two weeks, I've become completely dependent on it in these scenarios:
Commuters: Hang it around your neck on the subway with 30 settings to keep you cool while wearing a mask, and keep your makeup looking its best after getting off the bus;
Gymgoers: Hold it handheld with 80 settings after a run for a quick cooldown without getting a cold, and more hygienic than the big fans at the gym;
Office Workers: Use it on your desk with 40 settings to keep your keyboard clean and silent during video conferences without stealing the show;
Campers: Hang it on a tent pole with 60 settings to blow away moisture at night, and dim the LED screen without disturbing your sleep.
