## Description

Some buyers need a compact hand tool for occasional light work, others want cordless power for stubborn fasteners and vehicle or equipment repairs. The Alloyman CJBS-2000am is aimed at the latter, with a brushless motor and three selectable speed settings.

Its stated maximum breakaway torque is 1,500 ft-lb (2,000 N.m). The kit includes two 4.0Ah batteries, a charger, and three impact sockets, so it comes with more than the wrench alone.

That combination makes it relevant for truck or trailer tire changes, rusted bolts, and other heavy-duty repairs. The figures describe the product’s listed capabilities, not a guarantee that every fastener will release the same way.

## Product specs

- Type: Cordless impact wrench
- Model: CJBS-2000am
- Drive: 1/2 inch
- Maximum listed breakaway torque: 1,500 ft-lb (2,000 N.m)
- Power: 20 volts
- Motor: Brushless
- Speed settings: Three
- Battery: Two 4.0Ah Li-ion packs
- Included: Charger and impact sockets in 17mm, 19mm, and 21mm
- Material: Metal
- Color: Orange Red

The three modes are listed at 159 N.m and 0–1,050 RPM, 590 N.m and 0–1,500 RPM, and 2,000 N.m and 0–2,100 RPM. That range gives the user settings for lighter tasks as well as higher-demand fastener removal. The socket sizes are useful for common lug-nut work, though the kit only specifies those three sizes, check that a supplied socket fits the fasteners you plan to work on.

## Getting the most from it

The cordless format suits jobs where an air hose is inconvenient, such as changing a truck tire away from a workshop or moving between vehicles and farm equipment. Compared with basic hand tools, an impact wrench is the more relevant approach when fasteners are stubborn and repeated loosening is part of the task. For occasional low-force work, a simpler hand tool may be enough, this set is geared toward heavier repairs rather than being a general-purpose driver.

You’ll appreciate it if your work regularly involves lug nuts, rusted bolts, or equipment maintenance and you want batteries and sockets included. The three settings let you select a mode for the job instead of treating every fastener as a maximum-power task.

## How to use it

Choose a supplied impact socket that matches the fastener, then select one of the three speed and torque modes for the work at hand. The lower listed setting is intended for more delicate tasks, while the higher modes are presented for general repairs and heavy-duty removal. A practical use case is taking the wrench, charger, and battery packs to a trailer or vehicle for a tire change, rather than relying on a corded setup.

The product information lists charging from empty to full in two hours. Having two battery packs provides a second pack for the work, but does not establish how long either one will last in a particular job. Buyer feedback is generally favorable about torque, ease of removing lug nuts, and usefulness for automotive or farm tasks. Battery life is a more divided point: some buyers report long runtime, while others mention batteries quitting or performing poorly.

## Buying verdict

The CJBS-2000am is worth considering for buyers who need a cordless impact wrench for demanding vehicle or equipment work and value a kit with two batteries, a charger, and three sockets. Its modes offer more choice than a single-speed tool, while the included socket sizes are a defined rather than expansive selection. You may want to skip it if your work does not call for an impact wrench’s higher-force role, for light, occasional fastening, a simpler tool may suit the job. The mixed battery feedback is worth weighing if dependable runtime is central to your decision.
