Pretty much. Mine was cheap, but my favorite feature is the targeted auto stop. So I set it to a pressure, and it stops when it reaches it automatically, which no gas station pump ever did for me. So I can get them all to the exact same pressure without stopping to check where I'm at a bunch mid fill-up.
Ah ok - if the gas station doesn't have such a machine that's pretty useful. My next gas station has such a compressor, I enter the pressure and it does everything automatically once the hose is connected.
Anyways, keeping your tires at correct pressure probably pays for such a pump in a short time.
Bonus points if it also includes jumper cables with that battery. Having a portable jumper when your batter dies is insanely useful.
However, the model I have doesn't hold a charge forever, so I find that I have to recharge it every couple months or else it will be dead the next time I actually need it. An unfortunate flaw so I'd look for reviews that mention whether that's the case for any you look to purchase
Thats a thing (stand alone) on my list to purchase. Except I've bought a new car battery not longer than a year ago. So I guess that should hold up. Did I just jinxed myself?
