Compact Rechargeable Cordless Tire Inflator

My 12 Volt DC Air Compressor died on me recently and I wish to replace it.

Any thoughts, experiences with these rechargeable lithium battery operated portable tire inflators? Any recommendations for specific models? Something small and easy to store is preferred.

Buy the one that matches your cordless tools at home.

The Milwaukee is really nice and has auto shutoff at a preset pressure.

I actually got that one a couple months ago. Works. Not the quickest and the readout is a bit high until you stop filling, but it works.

It makes sense to get one in the system that you already own. I have Ridgid 18V tools so I bought their inflator and it's been great for what it is.

It's not a substitute for a heavier duty one that connects directly to the battery terminals, and not a substitute for my onboard ARB compressor, but a convenient way to top off tires that are a little low.

Project Farm has a good comparison review of some available options, although these are probably larger than what you're looking for:

The option from Canadian Tire has a USB-c cable for charging the lithium battery and can also operate from a 12-volt cigarette lighter port in the vehicle:

  • Can go from 24 to 34 PSI in less than 2 minutes; maximum pressure 150 PSI
  • Contains a 12V DC car charger
  • Removable rechargeable lithium-ion battery
  • Compact and lightweight design makes it portable and easy to carry
  • Can inflate 4 tires in 1 charge
THAT SAID, I just read a few reviews on Amazon.ca and will not be getting this one. Battery life is short. Takes a long time to fill truck tires. There is no obvious replacement for the rechargeable lithium battery.

Need Bigger Tires
I had a ctire inflator previously that claimed similar to that, also ran off the accessory port. The key to those claims is that they are for something like a 15" car tire. Mine would take around 1/2hr to refill a flat tire on my X...

What is your use case? Occasional use to top up a tire or two, or airing up all four after offroading?

The cig lighter aka 12v accessory port is usually <10A draw because of the fuse size. A decent 12V compressor that connects directly to the battery terminals, like a Viair 88P, might be more than twice that, ~20A. The ARB I have permanently installed has a maximum ~30A draw IIRC.

Cig lighter connected compressors are, in my experience, pretty weak and slow. They also tend to have lower duty cycles, so you have to let them cool down after X minutes of use, otherwise they'll overheat. I've been able to run my starter battery connected and onboard units pretty much continuously without cooking them.

The compact battery operated units you're asking about probably have more in common with the cig lighter connected ones... they work alright in a pinch and will fill a tire eventually, but they're just not as powerful as other options. If you opt for one of these, I would recommend as others have said getting one with a battery that matches other tools you may have.
