Verdict. Pick 18v if you need the stated torque: the ACROPOW states 1850 ft-lbs for heavy-duty work, and the WorkBless states 630 ft-lbs with sockets included. Pick 12v if the work is lug nuts and roadside tire repair: the Wagan states 271 ft-lbs in a kit with sockets, fuses and a case, plus the only stated warranty here at 1 year.
A 12v vs 18v impact wrench choice comes down to the bolts you actually turn. The 18v side here states the bigger torque figures: 1850 ft-lbs and 630 ft-lbs on cordless tools. The 12v side states 271 ft-lbs in a kit built for tire work. This comparison puts the two 18v listings against the one 12v listing on what each states.

12v vs 18v impact wrench: torque on each side
The 18v listings state 1850 ft-lbs of loosening torque on the ACROPOW and 630 ft-lbs on the WorkBless. The 12v Wagan states 271 ft-lbs of max torque. The ACROPOW states its figure for heavy-duty automotive, industrial and construction applications; the Wagan states its figure for lug nuts on most passenger vehicles. Do not call a side better on torque unless the figures are stated clearly on both sides: here they are, and the 18v figures are the higher stated ones.
Speed and control
The ACROPOW states three speed settings with a reverse auto-stop that prevents over-torquing. The WorkBless states three preset modes with a variable-speed trigger and a reverse auto brake. The Wagan states a no-load speed of up to 5000 rpm with a 3-position switch for forward, lock and reverse. Speed figures are stated on all three, so the control comparison is direct.
Anvil size and sockets
The ACROPOW states a 3/4 in hog ring anvil. The WorkBless states a 1/2 in drive with 4 Cr-V sockets in 17, 19, 20 and 21 mm. The Wagan states a 1/2 in drive with two sockets and two fuses in a locking molded case. The anvil and socket figures are stated on all three, so match the drive size to the sockets you own.
Weight and batteries
The Wagan states 5 lb and the ACROPOW states 6 lb; the WorkBless states no weight figure. Both 18v listings are stated as bare tools or tool-only, working with Milwaukee 18V or Makita 18V batteries that are not included. The Wagan is a 12V DC tool, stated with no battery platform. Weight is unclear on the WorkBless, so that comparison stays open.
Warranty
The Wagan states a 1 Year Limited Warranty, the only stated term here. The ACROPOW and WorkBless state no warranty term in the shown text. Where a term is stated, that is the coverage to hold against.
Torque on each side, in the listings’ words
The stated torque figures are 1850 ft-lbs of loosening torque on the ACROPOW, 630 ft-lbs on the WorkBless and 271 ft-lbs of max torque on the Wagan. The ACROPOW states its figure with 2500 N.m in parentheses for heavy-duty automotive, industrial and construction applications. The WorkBless states its figure with 850 Nm in parentheses for lug nuts, rusted bolts and fasteners on cars, trucks, trailers and mowers. The Wagan states its figure for lug nuts on most passenger vehicles. For the stated figures alone, the 18v side is the higher torque side, and the gap between the stated 1850 ft-lbs and the stated 271 ft-lbs is the whole comparison.
Sockets and anvils
The anvil and socket figures are stated on all three. The ACROPOW states a 3/4 in hog ring anvil that keeps sockets locked during high-torque work. The WorkBless states a 1/2 in drive with 4 Cr-V sockets in 17, 19, 20 and 21 mm, plus a buckle and a manual. The Wagan states a 1/2 in drive with two sockets, two fuses and a locking molded case with an integrated handle. The ACROPOW states a bubble level indicator is not among its features; that feature is on the Wagan, stated to keep the wrench square to the lug nuts and lessen the chance of rounding them. Match the stated anvil to the sockets you own.
Battery platforms and bare tools
The battery situation is stated clearly on all three. The ACROPOW states it works with Milwaukee 18V batteries, and states it is an independent compatible tool not manufactured by Milwaukee, with battery and charger not included. The WorkBless is stated as tool-only for Makita 18V batteries. The Wagan is a 12V DC tool, stated with no battery platform at all. The ACROPOW states built-in low-voltage protection to safeguard the tool and the battery. For a shop already on a battery platform, the stated compatibility is the deciding figure; for roadside use, the stated 12V DC tool is the self-contained answer.
Dimensions and build
The stated weights are 5 lb on the Wagan and 6 lb on the ACROPOW; the WorkBless states no weight. The stated lengths are 9.5 in on the Wagan and 10 in on the ACROPOW. The Wagan states a plastic and rubber build with an ergonomic design. The WorkBless states an ergonomic anti-slip handle and an alloy steel material. The ACROPOW states a metal build with an ergonomic anti-slip handle. With one weight unstated, the stated 5 lb and 6 lb figures are the only direct comparison, and the WorkBless stays open.
What no listing states
The WorkBless states no weight and no warranty term in the shown text. The ACROPOW states no warranty term. The Wagan states no brushless motor and no 18V option. None of the three states a duty cycle figure. Where a listing leaves the figure unstated, we say so rather than scoring on the missing figure, which is why the weight and warranty comparisons stay open on the 18v side.
The three impact wrenches
How we scored them
Each wrench is scored on performance, build, value, safety and warranty. Stated torque, speed settings and features decide performance; stated reverse auto-stop and low-voltage protection decide safety; the stated warranty term decides warranty, and where none is stated the score is zero. The comparison table and the product cards show the rest.
