Tire inflator with gauge that uses 12v auto

The best 12V inflators have alligator clips you attach to your battery. The very good ones are often used by off roaders that deflate and reflate when going back on the road. Viair is well respected in the off-road community and they have a few cigarette plug models under $100.
A few weeks ago I cut the end off mine and put clips on it. Makes it easy to use on the ATV. The thing never was long enough to reach the back of my truck anyway.
 
For any one who might run up on this is the future.. the ViAir "RV" models have longer hoses. Also to get over 60psi you'll need an higher line model with the alligator clips.
 
Do the people who buy the 12V inflator keep it in the trunk? Or at home? If at home do you have other air compressors at home?
I have the 5 harbor freight ones that reside in each vehicle with a small plug kit added in the bag. I have a Viair 88P (clips to battery) in the beach bag with extra recovery stuff for the Pilot (each car has at least a strap, shackles, hitch pin and folding shovel at all times anyway). At home I have multiple plug compressors. My most used one is the KOBALT 3 gallon Hot Dog from Lowe's. It's pretty quiet, lightweight, recovers quickly and goes to 150psi.
 
This is a great inflator, especially if you can secure one at this price:

Milwaukee M12 Inflator
I’ve had one for about two years, works great and very reliable.
How long does the charge last if left in the vehicle? Is there a charge in the car option (besides having an inverter)?

We have a bunch of Dewalt cordless stuff on our fire engine. We also have a battery pack "adaptor" that has a regular AC plug on it so we can run
off the generator if the batteries die.

I keep mine in my car . There small and portable and should be kept in your car for emergencies . I've had my low tire light come on many times when I'm on the road and driving it that way can cause a blowout .
 
I have a milwaukee 12 volt. And the milwaukee m18 volt inflator. They both are awesome. The 12 volt I mostly use for my tractors and my bmw. The m18 version I use for my f350 and my toyota sequoia with 33 inch mud tires. If I go off road I always take the m18 inflator so I can drop tire pressure to about ten to 12 psi over loose sand or mud.. i run my mud tires at 42 psi on the road.
I use a six amp hour milwaukee 12 volt battery and 5 or 7 amp m18 battery.
 
I have two portable inflators and two mid size air compressors and one 75 gallon 5 hp 240 volt shop compressor.
I keep the 12 volt battery and 18 volt battery compressors in two of my vehicles..

My 12 volt milwaukee will inflate from 30 psi to 50 psi... about 8 large truck tires on half a battery.. milwaukee 12 volt / 6 amp battery
 
I've been using a 12v Intercompressor for decades. If it conks out, I'd be looking at something like the Viair.

But, dragging the cord out, and crawling into the car has gotten old, especially since I rarely have to do more than check pressures and top off by a couple pounds.

Since I've become invested in the Ridgid tool system, I'm looking to pick up their cordless inflator, which can also run off a cord as well.

One thing to be aware of, for any portable, is their duty cycle. Even the US-made IC noted above, of generally good quality, has seen its 12v plug deform from heating up from being used for long durations.

The plug's length is also too shallow for some 12v outlets, so I have a battery terminal-to-12v adapter cord for it, which also removes risk from overheating an outlet in the car.
