A compact electric screwdriver is useful for flat-pack furniture, switch plates, toys and repeated light fasteners. It is not a substitute for a drill/driver when a job needs drilling capacity or high torque. We reviewed current manufacturer pages and manuals for three exact 4V models. HandyTested has not runtime-tested, torque-tested or assembled furniture with these tools.
Quick comparison
| Exact model | Control and charging | Documented package | Best fit |
|---|---|---|---|
| SKIL SD561201 | 230 RPM; forward/reverse collar; micro USB | Cable, eight bits, drill bit and holder | Light fastening near electrical fixtures, with sensor limits understood |
| BLACK+DECKER BDCS20C | 180 RPM; inline grip; integrated 4V battery | Manufacturer page lists screwdriver only | Simple household fastening in narrow spaces |
| WORX WX240L | 300 RPM; three torque levels; USB-C | 12 bits, holder, cable and case | Users wanting selectable force and a documented kit |
Manufacturer RPM and torque figures are not directly comparable to measured performance under load. Check the exact seller package and charging connection before buying; prices and stock vary.
SKIL SD561201: Circuit Sensor feature with important limits
SKIL lists a 230 RPM no-load speed, 1/4-inch hex collet, LED work light, micro-USB charging and forward/reverse collar for SD561201. Its Circuit Sensor is designed to detect electrical current in outlets, switches, cords and fixtures from up to one inch away. The package lists a charging cable, eight 1-inch bits, a 3/32-inch drill bit and a magnetic holder.
Trade-off: the sensor is a screening feature, not proof that wiring is safe. De-energize at the correct breaker, prevent re-energization and verify with an appropriate tester before touching conductors. Follow the SKIL manual’s sensor procedure and limitations.

BLACK+DECKER BDCS20C: straightforward inline driver
BLACK+DECKER documents 180 RPM and 35 in-lb for the compact inline BDCS20C. It uses a 1/4-inch hex chuck and an integrated 4V MAX lithium-ion battery. The inline body prioritizes simple access for light fastening rather than drill/driver versatility.
Trade-off: the current manufacturer page lists only the screwdriver under package contents even though the battery is integrated. Confirm the charging equipment and bits in the exact retail listing. There is no selectable clutch, so start carefully in soft material or small hardware.

WORX WX240L: three selectable torque levels
WORX specifies 300 RPM and three settings corresponding to 22, 33 and 44 in-lb for WX240L. The integrated 4V battery charges over USB-C. Dual LEDs, 12 bits, a magnetic holder, charging cable, storage case and manual shaft lock are documented.
Trade-off: use the lowest suitable setting to reduce the risk of stripping small screws or damaging soft furniture panels. The 4V format is meant for screwdriving, not the drilling and sustained high-load work expected from a drill/driver.

Match bit, pilot hole and torque to the fastener
- Choose the exact bit profile and size; a loose fit damages both bit and screw.
- Check for hidden wiring or plumbing and use a pilot hole when the material and fastener call for one.
- Seat the bit squarely, start at low force and stop when the fastener is flush.
- Finish delicate or precision hardware by hand when needed.
- Remove the bit and disconnect charging power before cleaning or inspecting the tool.
Wear eye protection when drilling or where chips can be produced. Do not drive into an energized fixture, use damaged bits or charge with an incompatible supply. Follow the furniture, anchor and fastener instructions as well as the tool manual.
How to choose
Choose SKIL when the documented bit package and circuit-screening feature fit your tasks and you understand that electrical verification still requires safe isolation and testing. Choose BLACK+DECKER for a simple inline tool when you will confirm charging accessories. Choose WORX when selectable torque levels, USB-C and a documented case-and-bit kit matter most.
Frequently asked questions
Can a 4V screwdriver drill holes?
Some packages include a small drill bit, but these tools are primarily screwdrivers. Use a drill/driver for larger holes or demanding material.
Does a circuit sensor prove power is off?
No. Detection can be affected by distance, construction and procedure. De-energize and verify according to accepted electrical-safety practices.
Were these screwdrivers tested by HandyTested?
No. This comparison is based on current manufacturer documentation and package details.
