Reviews & Ratings
The reviewer compares the Xiaomi Mijia Air Pump 2 Pro to the previous Xiaomi Air Pump 2 model, noting that the Pro version is significantly larger, heavier, and features a larger battery, longer hoses, an added back flashlight, and improved cooling design. Testing shows it inflates about twice as fast but uses twice the energy and runs hotter, making it less efficient than the original model.
