If you have to check the air pressure of the tyre (with Schrader valve) more often and use a hand or foot pump or even a 12V compressor, then the adapter with quick release plug (Quick Fix) makes the work much easier. Simply attach the adapter ”Quick Fix” to the valve connection of the air pump or the compressor and lock it. Now attach the quick release plug to the tire valve / Schrader valve. And off you go!
