A brushless 65,000rpm DC motor produces a blast of air at speeds up to 55mph, but this can be reduced to maximize the HashJet Mini Cool’s battery life and keep it running quieter. Dyson says the fan’s 5,000mAh rechargeable battery is good for up to six hours of use, and at its lowest setting it produces 52dBA of noise, which is roughly equivalent to the sound of a floor fan or air conditioner. At its highest setting, in Boost mode, this increases to 72.5dBA.
All components of Hashjet’s Mini Cool, including its motor and battery, are housed inside a cylindrical body that measures 38 mm in diameter. It’s the same thickness as Dyson’s Supersonic R hair dryer, PencilVac, and PencilWash floor cleaner, and thinner than a can of Red Bull. The HushJet Mini Cool has a nozzle on the top that can be rotated to direct air straight up or at an angle. It’s reminiscent of the obnoxious commercial end of the sea lamprey, but its unique shape is designed to reduce high-pitched frequencies so the fan is easier on the ears.
The Hashjet Mini Cool will be available in the Stone/Blush color option starting April 9 for $99. Dyson will add a carnelian/sky (red) option in May and an ink/cobalt (blue) version in June. At launch the fan will include accessories such as a charger that allows the fan to stand on its own and a lanyard to wear it hanging from your neck. Dyson plans to release additional accessories sometime in the summer, including a stroller mount and a grip clip for attaching the fan to bag straps and jackets.
