Before you is a portable tire inflator compressor that operates from the cigarette lighter and AC mains. The compressor is equipped with two electric motors that provide high performance. Suitable for cars, motorcycles, mid-size SUVs. Not suitable for trucks with large wheel radius. The power switch allows the compressor to be used either from the cigarette lighter in the car or from a household outlet. Convenient for use at home or when traveling. There's also a switch for inflating or deflating and two types of hoses - for inflating tires and mattresses. In addition, there is a built-in digital pressure gauge with backlight and auto shut-off when the set pressure is reached, which protects against overloading.
