The JISULIFE Handheld Fan Ultra2 is the brand's flagship 6-in-1 portable fan, pairing a 43,000 RPM Gen-III brushless motor with a bionic 9-blade turbine to deliver up to 17m/s of wind across 100 adjustable levels. Its massive 9000mAh battery runs for up to 25 hours, recharges in about 2.5 hours over 18W USB-C, and works as a power bank, while magnetic nozzles turn it into a duster and air pump and a built-in light adds SOS emergency lighting. Wrapped in an aluminum alloy body that weighs just 295g, it is the current Ultra-series flagship featured at CES 2026 and available in Dark Grey and Light Brown.
