HOTO portable pump has enough power to be used for inflating car tires, bicycle tires, motorcycle tires, and other vehicles. It is autonomous and runs on three 2500mAh batteries. To increase power, it can be connected to a 12V power supply — the port for this is located on the side of the housing. The system includes two pumps used for different purposes. The electric pump can inflate a standard car tire in 1 minute. A high-precision pressure sensor and intelligent board control the air inflation modes and can stop the process once the required pressure is reached. There are 7 automatic modes and 2 manual modes available.
