This portable machine is very easy to use as we just need to start the engine and connect the 12V compressor to the outlet, connect the hose and press the power button. No matter how easy it is. It's also handy for multiple uses, e.g. B. when needed for beach balls or bikes as it comes with 3 extra attachments. Just add that it has LED lighting, a digital display and a tire pressure detection function, which is very useful in an emergency. All in all, this is a valuable product.
