Greenworks keeps widening its 24V Pro line, and the newest entry is aimed squarely at automotive DIY work.
The IW5370 3/8-inch impact wrench is the compact option in the brand’s Pro impact wrench range, and Pro Tool Reviews just put it through real testing with an eye-opening conclusion: it trades blows with tools that cost three times as much.
The Specs
- Breakaway torque: 400 ft-lbs
- Fastening torque: 270 ft-lbs
- Speed: 2,500 RPM no-load, 3,600 IPM
- Modes: 150 / 300 / 400 ft-lbs presets, plus Auto Mode that cuts run-off when a fastener breaks loose
- Anvil: 3/8 in. friction ring
- Weight: 2.6 lbs bare, 3.7 lbs with a 2.0Ah battery
- Head length: 5.0 in.
- Price: $79.99 list, $69.97 at Walmart at the time of PTR’s review
How It Stacks Up
Milwaukee’s M18 FUEL 2854 posts 250 ft-lbs of breakaway torque at $249 bare.
DeWalt’s 20V MAX Atomic DCF923 hits 450 ft-lbs at $239.
At $79.99, the IW5370’s 400 ft-lbs undercuts both on price by a wide margin while out-torquing the Milwaukee.
The 5-year tool warranty matches what you get from the premium brands too.
Inside Greenworks’ own lineup, the IW5370 slots below the IW5550 mid-torque we covered when it launched at $99 bare.
The brand also lists IW5800 (750 ft-lbs) and IW51500 (1,430 ft-lbs) models above it, so the 3/8-inch compact is the budget entry point into the Pro wrench family.
The Catch
Greenworks’ 24V PowerAll platform is a Walmart exclusive, so you’re shopping there or direct.
The battery design is genuinely different though.
24V packs use six cell rows instead of five, tabless construction for lower resistance, and a USB-C port on the pack itself.
All 24V batteries cross-compatible with more than 200 Greenworks tools, including the lawn equipment many buyers already own.
One honest caveat: PTR’s comparison numbers come from a single review, and long-term durability on a budget brushless motor is always an open question.
That 5-year warranty helps offset the risk.

We also covered the Greenworks IW5550 mid-torque launch.
The 24V Pro impact driver at $99.97 is the third Pro tool we’ve tracked if you’re building out this platform.
