The measured results
Every number below is read straight from the test. Scroll sideways to see all measurements. Products are listed in the order they finished.
| Product | 35 PSI test time | 35 PSI test accuracy | 80 PSI (20 minute cap) test result | Weight |
|---|---|---|---|---|
| 1Milwaukee M12 Compact Inflator$137.55 | 5 minutes and 30 seconds, fastest pump tested | measured at 35 PSI, gauge very accurate | gave up at 17 minutes 14 seconds, reaching 56.5 PSI on manual gauge (56 PSI per pump gauge); battery indicated low and heat was noted as an issue | not tested |
| 2Harbor Freight Pittsburgh Chicago Electric 12V inflatoraround $30 | about 10 seconds slower than the Milwaukee, roughly 5 and 1/2 minutes total, using auxiliary vehicle power this time instead of a power converter as in the earlier video | not tested | shut off at 13 minutes 24 seconds, producing 46 PSI | not tested |
| 3Ryobi One+ 18V inflator$122.99 for the inflator, battery, and charger | 6 minutes 24 seconds total (an initial run of 5 minutes 52 seconds read about 32.5 PSI on the analog gauge, requiring extra time to finish) | gauge read about 3 PSI high, showing 38 PSI when the tire actually had 35 PSI | survived the full 20 minutes, reaching 58 PSI, second place behind the DeWalt | not tested |
| 4DeWalt$204 for the battery, charger, and inflator | 6 minutes 40 seconds | pump gauge showed 34.8 PSI, measured right at 35 PSI | reached 59.2 PSI at the 20 minute cutoff (measured a little over 59 PSI), first place ahead of Ryobi and Milwaukee | not tested |
| 5Bauer$112.98 for the inflator, battery, and charger bought separately | 7 minutes 50 seconds | pump gauge read 35.5 PSI, manual gauge showed 36.5 PSI, fairly close | survived the full 20 minutes reaching 49.5 PSI per its own gauge (52 PSI on manual gauge), briefly the leader before being passed by the Ryobi | not tested |
| 6Wyostuff WUYASTA Double Cylinder Foot Air Pump$25.16 | 8 minutes 42 seconds | overinflated to 38 PSI | not tested | not tested |
| 7Air Hawk Pro$37.99 | 12 minutes 15 seconds to inflate a 215/70/15 tire, per the video's chapter marker; this duration is not spoken aloud in the narration | inflated to 36 PSI, about 1 PSI over the 35 PSI target | shut off at a little over 18 minutes, reaching 35 PSI, not enough to fully inflate the light truck tire | 1.91 lb |
| 8Avid Power 20V automatic cordless inflator$59.99 | not tested | digital gauge read only 18 PSI when the tire actually measured 48 PSI on a separate gauge; the automatic shutoff failed to trigger at the programmed 35 PSI and the pump had to be shut off manually at 48 PSI | gave up at a little over 13 minutes, reaching 43 PSI | not tested |
How it was tested
- time to inflate a car tire to 35 PSI
- pressure gauge accuracy at the 35 PSI target
- time and maximum pressure reached inflating a light truck tire toward 80 PSI within a 20 minute cap
- noise level (quietest pump contest)
“In my opinion, the Milwaukee M12 is the best pump for tires under 40 PSI because it inflates very quickly. However, it runs out of legs pretty fast once you get above 40 PSI making the DeWalt the best pump for over 40 PSI.”
Data notes and caveats
No single overall winner: the video crowns per-pressure-range favorites (Milwaukee M12 best under 40 PSI, DeWalt best over 40 PSI), so winner is left null and both verdicts are captured in the verdictQuote and each product's notes. Avid Power is separately called out as unsafe to buy due to a failed auto shutoff and inaccurate gauge. The description's Products Tested list and its affiliate links also name Kobalt and WORX cordless inflators, but neither brand is mentioned anywhere in the transcript with any test data; flagged to data/re-pull.txt as the transcript appears incomplete relative to the description, and confidence is set to low per that gap. Two visually similar but distinct Harbor Freight branded products appear: the cordless lithium-ion Bauer (tested fresh, $112.98 kit) and the corded 12V Harbor Freight Pittsburgh/Chicago Electric pump (winner of a prior video's 12V showdown, retested here via auxiliary power for comparison, not purchased new for this review).
