## At a glance

- Three speed choices allow lower-speed work for control and higher-speed operation when more power is needed.
- The 3/8-inch square friction-ring anvil is designed for quick socket changes.
- Halo light is claimed to reduce shadows and illuminate the work area for up to 10 minutes.
- The listed 2.0Ah battery supports PWR ASSIST mobile charging through a USB port. The charger is claimed to bring it from empty to 25% in five minutes.

## Pros

- Compact 4.8-inch listed length can suit overhead work and tighter access than a larger wrench.
- A 3/8-inch friction-ring anvil and three speed settings offer useful socket-change convenience and operating control.
- The kit contents list a 2.0Ah battery and PWR Jump charger alongside the tool.

## Cons

- The included battery is 2.0Ah, which may be limiting for buyers expecting extended work between charges.

## Before you buy

- Torque specifications are inconsistent across the listing. One feature claim gives up to 150 ft. lbs, while other manufacturer sections state 170 ft-lbs fastening torque and 220 ft-lbs nut-busting torque. Treat these as listing claims, not verified performance, and confirm which figures apply before purchase. The claimed five-minute charge is specifically from 0% to 25% for a 2.0Ah battery, and the Halo light claim is for up to 10 minutes.

## In the box

- 2.0Ah PWR CORE 20 battery with PWR ASSIST mobile charging (Included)
- Power adapter (Included)

## A good fit for

- DIYers and mechanics seeking a compact cordless wrench for fasteners that suit a 3/8-inch drive.
- Buyers who want three speed settings, a work light, and a battery and charger in the listed kit.

## Less suited to

- Those who need a 1/2-inch drive or confirmed high torque for heavy-duty fasteners.
- Buyers who require a larger-capacity battery for long sessions without charging.

## Customer feedback

Customer feedback describes the wrench as powerful and functional, with positive comments about build quality, battery charging, and loosening nuts. That reported experience is relevant to its stated compact 3/8-inch drive and included 2.0Ah battery, though it does not resolve the listing’s conflicting torque figures. Aggregate ratings lean positive but include lower-star ratings, so experiences are not uniformly favorable.
- Positive themes: Customers report strong power and useful functionality.
- Positive themes: Feedback highlights quality and fast battery charging.

The manufacturer’s explicit contents list names the impact wrench, a 2.0Ah PWR CORE 20 battery with PWR ASSIST mobile charging, an Auto PWRJump charger, and a belt clip.
### What torque does the wrench provide?
The listing is inconsistent: it gives a 150 ft. lbs claim in one feature and 170 ft-lbs fastening torque plus 220 ft-lbs nut-busting torque elsewhere. Confirm the applicable figures before relying on them.
### Does the kit include a battery and charger?
Yes. The listed kit contents include one 2.0Ah battery and one PWRJump charger.
