Mitsushi 21V impact wrench review: the biggest batteries here

The Mitsushi 21V is our Best Battery Life impact wrench: 320Nm, a stated 0-2,400 rpm, a brushless motor, and two 4.0Ah batteries for around ₱2,300. It publishes more of its specs than most rivals in this bracket, which counts for a lot in a category built on unverifiable numbers.

How much wrench is this?

320Nm through a 1/2in square drive, with a variable speed trigger and a stated 0-2,400 rpm. That’s comfortably enough for car lug nuts, which torque to 100-140Nm and might need double that when seized, and it covers motorcycle work and general disassembly without complaint.

The stated speed figure is worth pausing on. Most wrenches at this price advertise a torque number and nothing else. Mitsushi gives you torque and rpm, which is a step toward something checkable, even if there’s still no impact-rate figure or published test standard.

The variable speed trigger is the practical win. It lets you ease into a fastener instead of hammering everything at full tilt, which is what saves small bolts from being sheared off.

What are the batteries like?

The best here, and the reason for the award. Two 4.0Ah packs is more capacity than anything else in this category ships, and it matters more in an impact wrench than in a drill: the tool draws hard in short bursts, so a small pack empties faster than its rating suggests. Two large packs means a full set of wheels with charge left over.

The brushless motor is the right match for that load, running cooler and lasting longer than a brushed unit under repeated hammering.

What’s the “88VF” about?

It’s the one piece of marketing on an otherwise straight listing. The battery carries an 88VF badge, and VF is not a unit of anything. It isn’t volts, it isn’t newton-metres, and it exists to look like a big number. The real figures, 21V and 4.0Ah, are stated elsewhere on the same listing.

It’s not a reason to avoid the tool, but it is a reminder to read past the graphics. Our impact wrench buying guide covers the other tells worth knowing.

Is it sulit?

Around ₱2,300 as of July 31, 2026. Check the latest price on Shopee. For a brushless wrench with two 4.0Ah batteries, sockets and a case, that’s strong value, and it’s only a little above the KEELAT kits.

The comparison worth making is with the KEELAT KID004 at around ₱2,000. KEELAT claims 420Nm with no supporting figures; Mitsushi states 320Nm at 0-2,400 rpm and bigger batteries. On paper KEELAT wins, on evidence Mitsushi does. For a tool where the headline number is usually unverifiable, we’d rather have the smaller figure that comes with a speed rating.

Who should buy it

Buy this if you want long working time and a spec sheet with more than one number on it: weekend car work, motorcycle maintenance, or a home garage where the tool sits unused for weeks and needs to work when you pick it up. If you want a documented brand with PH service support, spend more. See how it ranks in our best impact wrenches in the Philippines roundup, or browse more on our Home Improvement page.

Alternatives to consider

If verified specs and dealer support matter most, the INGCO COSLI23011 is our Best Overall with a published 300Nm and a work lamp, at more than double the price. If you want the biggest claimed torque and the largest accessory kit for less, the KEELAT KID004 is our Best Value at around ₱2,000.
