PORTABLE COMPRESSOR

got a portable digital air compressor, which is essentially a compact, battery-powered pump used for inflating car tires, bikes, or sports equipment without needing to visit a gas station.
​Most of these generic models operate very similarly. Here is a quick guide on how to get it running:
​Quick Start Guide
​Check the Battery: Most of these units use a rechargeable lithium-ion battery. Make sure it's fully charged via the USB port (usually on the bottom or side) before first use.
​Connect the Hose: Screw the air hose into the top of the compressor and attach the other end to your tire valve.
​Power On: Press and hold the center power button. The LCD screen should light up, showing the current pressure.
​Select Your Mode: Use the "M" or mode button to toggle between presets (Car, Bike, Motorcycle, Ball). This usually changes the pressure unit (PSI, BAR, KPA, or kg/cm^2).
