Fanttik S2 Pro Cordless Electric Screwdriver vs Bosch PS21-2A 12V Max Two-Speed Pocket Driver Kit
Which should you buy? Our verdict on both, pulled from our full The Best Electric Screwdrivers: 4 Compared (and One to Skip) comparison.
The Fanttik S2 Pro gives the finest torque control and a full bit kit at a mid-range price. The Bosch PS21-2A adds far more torque and a real clutch for bigger jobs.

Fanttik S2 Pro Cordless Electric Screwdriver
Buy itA pen-style electric screwdriver with seven torque steps that goes low enough for electronics.
- Seven torque settings: 0.5, 1, 2, 3, 4, 5 and 6 N·m, using a mechanical-electronic hybrid torque control.
- 250 RPM motor and a 2000mAh battery that charges over USB-C at 5V/2A.
- 20 bits (5 long, 15 short), an extension rod and a 90° angle adapter in a magnetic case.
- 6 N·m tops out well below a 12V driver, so long wood screws are a stretch.
- Fanttik's run-time figure is by screw count (1500 M3 screws per charge), not by time.
- A slim body gives less grip for pushing hard into a screw.

Bosch PS21-2A 12V Max Two-Speed Pocket Driver Kit
Buy itA compact 12V driver with far more torque and a real clutch for bigger fastening jobs.
- 265 in.-lbs. of max torque with 20+1 torque settings.
- Two speeds, 0 to 350 and 0 to 1,300 RPM, with a 1/4 in. quick-change hex chuck and an LED.
- Kit includes two 12V Max 2.0 Ah batteries, a charger, two bits and a bag; the tool weighs 1.4 lbs.
- Heavier and larger than a pen-style screwdriver, at 6.5 in. long.
- Only two bits are included.
- Its lowest clutch settings are not rated in N·m, so fine electronics work is harder to judge.
