| 5Ingersoll Rand$273 (this price explicitly includes the tool, battery, AND charger together, unlike the other four brands' tool-only prices above; described as the most expensive brand tested, but not directly comparable to the other four tool-only prices) | 20-V 2.5-Ah battery, 30 in hose, rated for 7,500 psi, no light, no trigger lock, tool and battery made in Taiwan, charger made in China, 3 year warranty, no leg stand (lays on ground, collects dirt), no nozzle holder | 7.4 lb (3.4 kg) | 72 dB (stated as the quietest tool overall) | not tested | not tested | not tested | not tested | not tested | not tested | 73 minutes 15 seconds, the slowest of the five despite only a 2.5-Ah battery | 66 pumps, 35 grams, about 2.5 oz/min actual | 34 grams in 30 sec, nearly matching its no-load result and tying Performance Tool's 150 psi figure | 6,100 psi, the lowest of all five brands tested, well under its own 7,500 psi rating |
How it was tested
- grease pump output without load (grams and pump count in 30 seconds)
- grease pump output under 150 psi resistance (30 seconds)
- maximum pressure via hydraulic hose and gauge rig (psi)
- noise level (dB, measured 24 inches from tool)
- weight
- balance/ergonomics
- battery charge time
- ease of priming
“the milwaukee was a clear winner ... i really thought it was gonna be a lot closer competition between milwaukee and the other brands but milwaukee totally dominated the competition pumping grease faster and delivering a lot higher psi”
Data notes and caveats
Clean, well-resolved five-brand head-to-head (Milwaukee, DeWalt, Ryobi One+, Performance Tool, Ingersoll Rand); all prices introduce the brand in the same clause (no off-by-one risk) and all numbers are internally consistent with the closing recaps. Milwaukee is the explicit overall winner. Second place is an explicit declared toss-up/tie between DeWalt and Ryobi per the narrator ('it was pretty much a toss-up between dewalt and ryobi for the second place finish... dewalt delivers more psi but ryobi pumps grease a little bit faster'), so runnerUp is left null rather than forcing a single pick; the tie and each brand's edge are preserved in their product notes. Ingersoll Rand's $273 price is not apples-to-apples with the other four: it is the only brand priced as tool+battery+charger together, while the other four prices are tool-only. A separate manual pistol-grip grease gun was used as an un-tested baseline/control early in the video (48 pumps in 30 sec) and is not one of the five branded products, so it is excluded from products[].
