I feel like everyone should have one of these in their cars.It's important to be able to inflate your tires if needed.
Not every single store (at least near me) has air to use.This has an LCD screen so you can see how much air pressure you're inflating. Plus, you can preset what you need as to not overinflate, too.Very easy to use and understand.And, you can inflate other things, too-- like bikes, floats, etc.It's really convenient and saves you if you're in the middle of nowhere with low tire pressure.Definitely recommend.
