DEVTBLUN 21V Electric Ratchet Wrench Set – 60 ft-lbs Torque, 2x 2.0Ah Batteries, 3/8in Drive, 400 RPM, Includes 7 Sockets & Extension Bar

Overview

The DEVTBLUN 21V Electric Ratchet Wrench Set is built to empower quick pre-tightening and removal across a range of light industrial tasks. With a robust 21V motor delivering up to 60 ft-lbs (80 N.m) of torque and a 400 RPM variable speed trigger, you can tailor performance to the job — from delicate initial turning to steady, faster progress as needed.

Power, speed, and reach

Designed for efficiency, this cordless ratchet combines strong torque with controlled speed. The 3/8 inch compact head and a 4 inch neck let you access tight spots that are common in automotive, bike, and home projects. Weighing about 3 pounds, the tool remains easy to maneuver for extended sessions, while the insulated soft grip helps dampen vibration and reduce hand fatigue.

• 8000+ RPM? Not here — it uses a 400 RPM variable speed trigger for precise control.
• Compact 3/8 inch head with a 4 inch neck for tight spaces.
• Lightweight design at roughly 3 lbs for comfortable handling.

Long-lasting power for longer projects

The kit includes two 2000 mAh batteries and a fast charger, enabling extended work sessions with quick swaps. In practice, you can keep moving between tasks without frequent pauses, thanks to the dual-battery setup that can extend run time by a meaningful margin.

• Two 2000 mAh batteries offer extended operation per charge.
• Fast charger minimizes downtime between swaps.
• Alternating batteries helps maintain continuous workflow on larger projects.

Smart design and safety

Forward and reverse control along with a safety lock helps prevent accidental operation. A built-in LED light illuminates dark or confined spaces, improving visibility when working on screws in tight or recessed areas. For safety, avoid forcing large or tight fasteners and reserve final tightening for a manual wrench when needed.

• Forward and reverse with a safety lock for secure operation.
• Built-in LED light to brighten work areas without extra gear.
• Note on use: ideal for speedier pre-tightening and removal; final tightening may require manual torque.
