Fast Inflation: Unlike traditional tire inflators, we can get the job done within 2 minutes. This 12V portable air compressor features a twin-barrel design with a maximum output of 150 PSI and an output flow of 60 L/min Stability Technology: The bottom iron sheet ensures that the 12V air pump remains in the placed position and does not move during operation, making the air compressor more powerful and effectively reducing vibration and noise High Quality Metal Materials: We use strong metal, durable, rust-free pure copper rotors and aluminum cylinder heads
