If you enjoy doing basic maintenance on your car or truck, there are probably a few tools and gadgets that make basic jobs a bit easier and more pleasant. A digital tire inflator is one of those items.
Gauges are OK, but the truth is, they can be rather inaccurate, or they can be misread if you aren’t paying attention or if you are looking at it from an awkward or side view. A digital tire inflator, however, can’t be misread and they are, for the most part, very accurate.
Since tire pressure should be read when the tires are cold (in other words, after the car has been sitting all night in your garage) having a tire inflation device makes perfect sense. Proper tire pressure is vital to your gas mileage, the smoothness of the ride, as well as being a safety measure since tires that are underinflated tend to blow out more frequently.
If you have a compressor, some digital models will attach directly to the hose. If you don’t have a compressor, there are models that have a mini compressor, which allows you to add air, right there in your garage!
So now that you are ready to buy a digital tire inflator, how do you choose the best one? We are going to review some of the most popular models on the market so you can make an informed decision.

JACO FlowPro Digital Tire Inflator
- Compression: 200 PSI
- Hose Length: 18 Inch
- Power Source: 2 AAA Batteries (not included)
This is the name brand that nearly every automotive store carries and that you have probably seen. If you have a compressor, this is probably the digital tire inflator you want. The JACO has a solid steel body, along rubber cover to prevent damage. LCD display will stay on for 120 seconds (that’s 2 full minutes) before it automatically shuts off. A steel braided air hose means a longer lifespan and the lightening chuck has an automatic lock on, so you aren’t fumbling around trying to screw the chuck on. Has a quick start guide for those who haven’t used a digital tire inflator, and all the fittings you will probably ever need or use.
- 100 % Life-time Guarantee (for any reason)
- Name brand quality
- Professional grade without the professional price
- Over time, steel mesh can come apart and cause cut fingers
- Some claim the “lightening chuck” simply doesn’t work out of the box
- Latch compartment for the AAA batteries can break easily
The Final Word
While all the above digital tire inflators were reasonable priced, it would boil down to whether you have a compressor or not.
If you do not have a compressor or if you wanted a 12V tire inflator for emergency situations, we would choose the EPAuto Portable Air Compressor. With so many terrific features, including the powerful LED flashlight, it seems like a logical choice, even if it does seem to lose a bit pressure when you disconnect. We simply added a pound extra and problem was solved.
If you do have a compressor, the JACO FlowPro would be our recommendation. Maybe it’s the brand name, maybe it’s that amazing PSI, but with a 100% lifetime warranty, how could you say no?
