The compressor is supplied in a branded 70mai box, everything inside is in foam, it is impossible to damage the metal box of the device during delivery. Inside the instruction in Chinese, English and 2022, the front surface of the compressor is in protective films. The device itself is rigidly fixed in a metal box, there is enough space between the walls and the compressor for neat storage of the hose and power cable, and during operation for excellent cooling. The clip for car tires is plastic, but reliable, fastened tightly. We connect to the wheel, powered by a 12v outlet, the compressor comes to life and displays the current pressure on the screen. We set the required pressure, start it with the button and the compressor will clearly pump out the wheel to the set pressure, after which it will turn itself off. It works, in my opinion, quite quietly, and shakes quickly. A nice bonus - adapters for pumping balls, mattresses, etc. 70mai made an excellent compressor, technologically advanced, thoughtful, and even stylish.
