Probably a stupid question, but I'm one of those that used to take my old cars "to the dealer" for every schedule service interval and they dealt with ensuring the tire pressure was right every time. I've occasionally inflated at a gas station, but....I don't go to gas stations anymore unless my mower needs me too (and its days are probably numbered!). So for inflating at home or on a trip, do you guys use the 12v compressor that comes with the tire repair kit to inflate regularly, or something else? I see that portable tire inflators are a thing and not very expensive, so that's probably the alternative, but am I buying something I already have?
