The motor power is 33.6W, which is 51% higher than the previous generation; the lithium-battery capacity is 7.2Wh, about 30% higher. It has a new air-duct impeller design, a dust-removal force of 2.7kPa, and a wind speed of 80km/h. It has three-gear functions, realizes air-blowing synchronization, and is equipped with a brush
Features
-  High-power motor: The power reaches 33.6W, which is 51% higher than the previous generation, and can easily blow away stubborn dust. 
-  Lithium-ion battery: It has a built-in 7.2Wh lithium-ion battery, which is about 30% higher than the previous generation, and can provide about 210 cleaning times. 
-  New air duct and impeller: It adopts a fluid-dynamic air duct, a 42-millimeter integrated impeller, and has 20 built-in high-density spiral fan blades, which can reduce noise and improve air-supply efficiency, resulting in both increased air volume and pressure. 
-  Strong dust-removal ability: The dust-removal force reaches 2.7kPa, which is 80% higher than that of ordinary manual air blowers, and the cleaning effect is remarkable. 
-  High-speed wind: The BB2 has a wind speed of up to 80km/h, which is 230% higher than that of ordinary manual air-blowers, enabling it to clean a larger area simultaneously and improving cleaning efficiency. 
-  Multi-gear design: It has three gears: TURBO powerful dust-removal gear, OPTICAL optical dust-removal gear, and SILENT silent dust-removal gear, which can be freely switched to meet different cleaning needs. 
-  Air-blowing synchronization: When used in conjunction with the air-blowing function, the cleaning efficiency is doubled. It also has a built-in retractable storage brush with a hidden design. 
-  Auxiliary lighting lamp: It has a built-in auxiliary lighting lamp with a high-color-rendering-index light source (CRI≥90), which is convenient for cleaning dust in dark environments. 
Three levels of free switching
-  TURBO Dusting Powerful and efficient dust-blowing 
-  OPTICAL Optical Dust Extractor For camera CMOS cleaning 
-  SILENT Silent Dusting Stall Silent cleaning at only 55dB
