This post is brought to you in paid partnership with JISULIFE.
If you’ve been eyeing Dyson’s new handheld fan and wondering whether it’s really the best pick for surviving a heatwave, there’s a strong case that the answer is no. The JISULIFE Ultra2, the flagship from the world’s leading handheld mini-fan brand, beats Dyson’s handheld on the performance numbers that matter most, including airflow, cooling speed, and battery life. More importantly, it turns those numbers into the kind of everyday comfort you’ll actually notice, and it’s the one worth reaching for when the temperature climbs.
Why the Ultra2 is worth it
At the core of any handheld fan is one job: move enough air, fast enough, to actually cool you down. The Ultra2 is built around that. It delivers up to 16.8 m/s of airflow through a 13-blade design controlled by a 100-level roller dial, so you can dial in anything from a barely-there whisper to a full gale.
If a raw figure like 16.8 m/s doesn’t mean much to you, here’s a way to picture it: that’s about 60 km/h, roughly the speed of a car cruising through a city street, aimed right at your face. Dyson’s handheld tops out at 14.9 m/s, closer to 54 km/h. It sounds like a small gap on paper, but in real heat, that extra push is the difference between air that drapes over you and air that actually cuts through a sticky, humid afternoon.
That power also translates into how fast you feel relief. In head-to-head lab testing at 36°C and 60% humidity, the Ultra2 cooled a surface from 36°C down to 30°C in about 5 seconds. The Dyson took 13 seconds to do the same. In practice, that means you point it at the back of your neck after stepping off a hot train and you’re comfortable almost immediately, rather than standing there waiting for it to catch up.
Battery life measured in days, not hours
Here’s where the Ultra2 really pulls ahead for daily life. It runs up to 24 hours on a single charge from its 9000mAh battery, while Dyson’s handheld maxes out at 6.86 hours.
The way to think about that isn’t in hours, it’s in days. If you use your fan about 5 hours a day, a realistic amount across a commute, an afternoon out, and an evening walk, the Ultra2 will run for close to five days before it needs a charge. The Dyson, under the same daily use, taps out in roughly a day and a half. That’s the difference between charging your fan once a week and charging it every other morning. Over a long, hot stretch, one of those is genuinely freeing and the other is one more thing to remember.
When you do need to top it up, 18W fast charging over a two-way Type-C port gets it back quickly, and because that port runs in both directions, the fan doubles as a power bank for your phone in a pinch.
More than just a fan
The Ultra2 is built for real life, with details you don’t usually find in a handheld fan:
- LED digital display showing battery level and wind speed, so you’re never guessing how much runtime is left
- Aluminum alloy body that feels premium and holds up to being tossed in a bag every day
- Honeycomb airflow structure that keeps long hair from getting pulled into the blades
- Safety lock button so it won’t switch on by accident inside your bag
- Removable rear cover that pops off for easy cleaning, so airflow stays clean
- Magnetic nozzles that turn it into a focused dust blower or an inflator, plus built-in lighting with an SOS mode for the outdoors
The bottom line
The JISULIFE Ultra2 is a premium, high-performance handheld fan that goes toe-to-toe with Dyson’s flagship and comes out ahead on cooling, airflow, and battery life, the factors that actually decide whether a fan keeps you comfortable through a long, hot day. Judged on the standard that matters most for a handheld fan, how well and how long it moves air, the Ultra2 is the clear pick. For anyone gearing up for summer commutes, festivals, or just a stretch of relentless heat, this is the handheld fan to have.
