Our take on the Black Bull 12-Volt Portable Digital Tire Inflator Pump

The Black Bull 12-Volt Portable Digital Tire Inflator is a plug-in pump that runs off a car's 12V lighter socket and inflates tires to a set pressure, then shuts off on its own. It has a digital PSI gauge, a 24-inch hose and a 9-foot power cord, and it weighs about 2 pounds. Its best new price is $29.99 at Tractor Supply Company as of November 7, 2026, with 4 stores listing it new.

Best forDrivers who want a set-and-forget inflator in the trunkFilling car, trailer and bike tires at homeBuyers who want a digital gauge without paying muchOccasional top-ups rather than shop-level air demand
Pros
  • Set the target PSI and it stops automatically
  • Digital gauge reads in PSI, easier than a stick gauge
  • 12V lighter plug works in any car without wiring
  • Light at about 2 lbs and small at 8 x 8.5 x 3.5 inches
  • Long 9-foot cord reaches all four wheels on most cars
Cons
  • 8-minute continuous duty cycle means cool-down breaks on big jobs
  • 27L/min flow is slow for large truck or RV tires
  • Cord-and-hose setup is bulkier than a cordless inflator
  • No battery, so it only works when plugged into a 12V outlet

Questions and answers

How accurate is the digital gauge and auto shutoff?
The gauge reads in PSI and the pump stops when it reaches your set pressure. Expect small differences from a separate gauge, so check with a handheld gauge after the first fill.
Can it inflate a completely flat car tire?
Yes, but slowly. At 27L/min it takes several minutes to bring a passenger tire from flat to about 32 PSI, and the 8-minute duty cycle may require a pause.
Does it work on truck or RV tires?
It can reach 150 PSI, but the low flow rate and 8-minute duty cycle make it a poor fit for large-volume tires. It suits passenger cars, trailers and bikes.
What comes in the box?
The pump, a 24-inch hose and a 9-foot 12V lighter power cord. No separate battery or AC adapter is included.
Is $29.99 a good price?
It is the best new price among the 4 stores listing it as of November 7, 2026. For a digital auto-shutoff inflator, that is a low entry price.
Can I use it with a 12V socket in the trunk?
Yes, any standard 12V lighter port works. The 9-foot cord gives extra reach from a front or rear outlet.
Where is the Black Bull 12-Volt Portable Digital Tire Inflator Pump cheapest?
At Tractor Supply Company, for $29.99, 34% under what the other stores charge, as of our latest check.
Where can I buy the Black Bull 12-Volt Portable Digital Tire Inflator Pump?
5 stores we checked sell it, including Tractor Supply Company, Buffalo Corporation, Walmart, BisonOffice.com, Zoro.
