I wasn't sure but I decided to give it a try. It comes with everything you need including a Presta to Schrader adapter. I charged it and tried it on my bike. Set it to the desired pressure and when it detects that the tire pressure is under pressure, it will stop. Turn off the pump and you're done. I haven't had a chance to test the accuracy but I expect it to be as good as my hand pump and much easier to use.
