The JISULIFE Ultra2 surpasses Dyson’s handheld fan in cooling performance, and here’s why it's the best choice for this summer.

      This post is presented in collaboration with JISULIFE.

      If you've been considering Dyson's latest handheld fan and are curious if it's truly the best choice for enduring a heatwave, you might find a compelling argument that suggests otherwise. The JISULIFE Ultra2, the leading model from the top brand in handheld mini-fans, outperforms Dyson’s device in crucial performance metrics such as airflow, cooling speed, and battery life. More significantly, it translates those specifications into tangible comfort that you will genuinely appreciate, making it the ideal choice when temperatures soar.

      Reasons to Choose the Ultra2

      The primary function of any handheld fan is to move enough air rapidly enough to provide cooling. The Ultra2 is designed with this purpose in mind. It offers an airflow of up to 16.8 m/s through a 13-blade configuration controlled by a 100-level roller dial, allowing you to adjust from a soft whisper to a strong breeze.

      If a raw figure like 16.8 m/s doesn’t resonate with you, consider this: it's equivalent to about 60 km/h, similar to the pace of a car driving along a city street, directed right at your face. In comparison, Dyson’s handheld fan peaks at 14.9 m/s, which is about 54 km/h. Although it may seem minor on paper, that additional force makes a significant difference in real heat, transforming air that simply drapes over you into air that penetrates the sticky, humid afternoon.

      This power also affects how quickly you experience relief. In controlled lab tests at 36°C and 60% humidity, the Ultra2 cooled a surface from 36°C to 30°C in approximately 5 seconds, while the Dyson took 13 seconds for the same result. This means you can aim it at your neck after exiting a hot train and feel comfortable almost instantly, rather than waiting for it to start working.

      Battery Life Measured in Days, Not Hours

      This is where the Ultra2 truly excels in everyday use. It operates for up to 24 hours on a single charge from its 9000mAh battery, while Dyson’s handheld lasts only 6.86 hours at most.

      Think of that in terms of days rather than hours. If you use your fan for about 5 hours daily—which is realistic with a commute, an afternoon outing, and an evening stroll—the Ultra2 can last close to five days before requiring a charge. The Dyson, under the same daily usage, runs out in about a day and a half. This is the difference between charging your fan once a week versus every other morning. During a prolonged heatwave, one option offers significant freedom, while the other adds another task to remember.

      When you do need to recharge, the 18W fast charging through a two-way Type-C port allows for quick replenishing, and since the port works in both directions, the fan can also serve as a power bank for your phone in emergencies.

      More Than Just a Fan

      The Ultra2 is designed for real-life usage, featuring aspects rarely seen in handheld fans:

      - An LED digital display showing battery level and wind speed, so you’ll know how long it can run.

      - A durable aluminum alloy body that feels premium and withstands daily wear when tossed in a bag.

      - A honeycomb airflow structure that prevents long hair from getting caught in the blades.

      - A safety lock button to ensure it doesn’t turn on accidentally in your bag.

      - A removable rear cover for easy cleaning, ensuring airflow remains unobstructed.

      - Magnetic nozzles that allow for attachment as a focused dust blower or inflator, plus built-in lighting with an SOS mode for outdoor use.

      The Conclusion

      The JISULIFE Ultra2 is a high-quality, performance-driven handheld fan that competes with Dyson’s top model and surpasses it in cooling, airflow, and battery life—key elements that genuinely determine how effectively a fan keeps you comfortable on a hot day. When assessed on the criteria that matter most for handheld fans, specifically their ability to move air efficiently and for extended periods, the Ultra2 stands out as the preferred choice. For those preparing for summer commutes, festivals, or just enduring a series of scorching days, this is the handheld fan to choose.
