Free from the restrictions of power cords and plug sockets, this fan provides a refreshing natural breeze whenever and wherever you need it. The built-in 33.6Wh lithium-ion battery pack and 12V low voltage design will ensure you can enjoy the cool breeze even during unexpected power outage. The magnetic charging dock is equipped with overcharge protection. Charging will be automatically stopped once the battery is fully charged. Compared with traditional fan blades, the 7+5 double-layer wing-shaped blade of Xiaomi Smart Standing Fan 2 Pro can generate much softer breeze for your comfort. The inner-layer and outer-layer fan blades each generates air flow at different speed, which effectively eliminates air vortex, resulting in a wider, softer and more comfortable natural breeze. On the basis of the randomly simulated natural breeze algorithm, the design of double-layer fan blades enable the inner-layer blades to disrupt the focused air flow generated by the outer layer blades, making the ventilation wider and more gentle and bringing you even better experience than the breeze you find in nature. With long time research and data collection on natural wind, our R&D team developed a proprietary algorithm that simulate the irregular changes of natural breeze. Adjustable wide-angle ventilation up to a maximum distance of 14 metres, to cool the whole room more efficiently. In addition to the traditional control buttons on the top, the fan supports voice control, remote control via the Mi Home/Xiaomi Home app, and smart interaction with other Xiaomi smart home devices. Switch between natural breeze and standard ventilation as well as different speed settings in the Mi Home/Xiaomi Home app to adjust the air flow to meet your needs. The dual use of desktop and floor can be adjusted through the one-click disassembly button which made up by two-section metal poles.
