This is a portable air compressor that operates on 12 volts via the car's cigarette lighter, making it suitable for use on the go. The device provides a maximum pressure ranging from 250 to 300 PSI, which is suitable for inflating car tires, bicycles, and sports balls. It features a compact and lightweight design (approximately 300-365 grams), and includes a built-in mechanical pressure gauge for checking pressure during inflation.
