Overview
At 4 volts and 180 RPM, the BLACK+DECKER BDCS20C is a compact battery powered driver weighing about 1 pound, sized for light screwdriving rather than heavy drilling.
BLACK+DECKER's 4 volt lithium line targets small household jobs, tightening loose screws, assembling furniture, hanging light fixtures, rather than boring holes in wood or masonry, and the 180 RPM speed and 1 pound weight on the BDCS20C both point to that lighter use case.
- 4 volt battery power
- 180 RPM speed
- About 1 pound weight
- 4.6 average rating
Who it's for
Homeowners who want a small, light driver for quick screwdriving jobs around the house. Not a substitute for a full-size drill/driver on demanding drilling tasks.
Pros and cons
- Compact 1 pound weight for one-handed use
- Simple battery powered operation
- Low voltage and speed limit it to light screwdriving
- Not built for drilling holes
Performance notes
At 4 volts and 180 RPM, output is modest by design, enough torque and speed for driving screws into soft material but well below what a standard 12 or 18 volt drill/driver delivers.
