How does it perform?
The JISULIFE Portable Handheld Fan Ultra2 delivers impressive power with a 100-speed control system that lets you dial in exactly the airflow you need.
Here’s the reality check on noise: this thing gets loud—much louder than your typical portable fan at any speed setting. Testing revealed noise levels of 74.6 dB at full speed (about as loud as a vacuum cleaner or alarm clock), 63.3 dB at 50% power (normal conversation level), 58.3 dB at 25% power (busy office), and 50.5 dB at minimum (quiet as a refrigerator hum). Translation? Skip bringing this to movie theaters or weddings unless you want dirty looks. The lower settings are manageable for personal use, but even then, it’s noticeably louder than traditional handheld fans.
Battery life ranges from approximately 1.5 hours at maximum speed to 25 hours at minimum speed, with a 2.5-hour quick charge. At 10.5 oz, it’s compact and lightweight enough for everyday carry—only 2-3 oz heavier than traditional portable fans that weigh 7-8 oz. The big difference? This fan delivers about 4x the power of traditional models, though that extra power comes with the increased noise.

The zero-blade design means no worries about fingers or hair getting caught. The built-in emergency light offers three brightness levels plus a strobe mode for safety situations. It includes an adapter for inflating air cushions, and here’s a cool bonus—you can actually use it to stoke a campfire. The 9,000 mAh battery doubles as a power bank with enough juice to fully charge an iPhone or other smart devices. The solid construction feels premium and delivers real performance, though at roughly $80 compared to $13 for traditional portable fans, you’re paying significantly more for those upgrades.

What’s it do best?
The JISULIFE Portable Handheld Fan Ultra2 is the premium option in the portable fan world—think Dyson or Apple levels of build quality and performance. This isn’t a cheap throwaway gadget; it’s a well-crafted tool that feels substantial in hand.
What really sets it apart is how everything comes together: the intuitive jog dial makes speed adjustments effortless, the zero-blade design eliminates any safety concerns about tangled hair or pinched fingers, and the emergency light with strobe mode adds genuine utility beyond just cooling. The air cushion adapter opens up creative uses—yes, even stoking campfires—and the power bank capability means you’re carrying a phone charger too.

The trade-offs are real, though. At $80 versus $13 for traditional portable fans, you’re paying a serious premium (though the weight difference is minimal at just 2-3 oz). The noise levels limit where you can use it—definitely avoid quiet environments like movie theaters or weddings. However, at lower speed settings, the fan becomes much more manageable for personal use.
Bottom line: if you value performance, durability, and premium features over a basic disposable fan, the exceptional build quality and versatile functionality make this a worthwhile investment. Just know what you’re getting into with the noise.
Testing Results
Noise Levels




Real-world testing measured actual noise levels at 2 feet away:
- Full speed (100%): 74.6 dB—as loud as a vacuum cleaner or alarm clock
- Half speed (50%): 63.3 dB—normal conversation level
- Quarter speed (25%): 58.3 dB—busy office environment
- Minimum speed (1%): 50.5 dB—refrigerator hum
The 100-speed range provides precise control, but this fan runs louder than traditional portable fans at all settings. It’s unsuitable for quiet environments like theaters or formal events, though lower settings work fine for personal use.

Battery Performance
- Runtime: 1.5 hours at maximum speed to 25 hours at minimum speed, depending on your speed setting
- Charging time: 2.5 hours with quick charge feature
- Battery capacity: 9,000 mAh—enough to fully charge an iPhone
- Power bank feature: Yes, can charge phones and smart devices

Design & Usability
- Weight: 10.5 oz (297g)—manageable for sustained use, only 2-3 oz heavier than traditional 7-8 oz fans
- Dimensions: 5.31″ (length) × 2.95″ (width)
- Control interface: The jog dial for adjusting fan speed is intuitive and easy to use. However, the light button is positioned directly next to the power switch, making it easy to accidentally activate when you don’t want it. There’s also a slight delay when toggling between light modes, which can feel a bit stuttery. Overall, the controls are accessible, but the button placement and toggle lag could be improved.
- Safety features: Zero exposed blades eliminate concerns about fingers or hair getting tangled
- Emergency light: Three brightness levels plus strobe mode for safety situations
- Extra features: Includes adapter for inflating air cushions (can also be used to stoke campfires)
Maintenance
The device may require occasional cleaning, especially in dusty environments. It comes with a small duster and screwdriver to remove the back plate for cleaning. The process looks a bit fiddly, and the cleaning interval will vary based on your environment—more frequent in dusty areas. Testing didn’t require this step yet, so long-term maintenance requirements are unclear.
