power screwdriver

Most cordless screwdrivers use rechargeable batteries; listed voltages include 4 V, 4.2 V, and 3.6 V. Charging options shown are USB charging and a dedicated charger/charger cable included with some kits. Some listings simply label the power source as “battery” or “cordless electric.”

Digital torque models show torque on a backlit display, offer multiple preset modes (examples list eight presets), and provide real‑time and peak modes. Some units also store session torque data for later review—examples show storage for up to 500 sets.

Reported maximum torques include roughly 3 Nm and 4.5 Nm. No‑load speeds are typically in the 200–250 RPM range (one listing shows 250 RPM).

Listings use labels such as “Battery,” “Cordless Electric,” and “Power Source: Battery.” They often note that a battery is required but may not be included; specific voltages like 3.6 V appear in multiple entries.

One digital torque model lists a range of 2.65–70.67 in·lbs with accuracy up to ±2%. Other compact models report torque in newton‑metres (examples: 3 Nm and 4.5 Nm).

Many listings describe a two‑position or pivoting handle that converts between straight and pistol orientations—typically rotating about 90°–180° or using a one‑button transformation. Some models note a swivel/pivoting grip and an ergonomic rubberized handle.

Kits typically include assorted Phillips, slotted/flat, hex, Torx, and PZ/PH bits in short (≈25 mm) and longer (≈50 mm) lengths. Some also list small HSS drill bits (e.g., 1.5 mm and 2.5 mm), bit extenders or flexible shafts, and metric sockets commonly in the 6–13 mm range.

Many models list built‑in LED illumination. Some compact screwdrivers note a single LED, while several kits specify two built‑in LEDs—one near the drive and one on the handle—to light the work area.

Listed dimensions vary from very compact hand‑tool sizes up to larger kit cases; reported heights range from about 1.63 inches to around 9 inches, and listed weights are roughly 1.74–3.35 pounds. (Listings do not always specify whether a measurement refers to the tool alone or the full kit/case.)

Kits commonly include a case or toolbox, assorted bits, bit extenders or flexible shafts, and chargers/USB power cords. Some also include metric sockets, a small ratchet head or extension bar, and—one digital torque kit listed—2 AAA batteries.
