battery screwdriver

Cordless screwdrivers most commonly use low-voltage rechargeable batteries in the ~3.6V–4.2V range (examples listed include 3.6V, 4.0V and 4.2V). Some products include an onboard rechargeable battery and charger, while others list “battery required, not included.” A few models are USB-chargeable and ship with a USB charging cable.

Yes—many cordless screwdrivers include built-in LED illumination. Listings commonly mention a front/head LED, and some kits add a second LED (for example on the handle or base) to better light the work area.

Cordless screwdrivers are typically charged either via a bundled rechargeable battery and dedicated charger (common for 3.6V–4V packs) or via USB power. Some models include a USB charging cable instead of a separate charger.

Compact one-handed drivers are often around 21 cm long and weigh about 300 g. Complete kits with cases vary more: case dimensions around 9 inches are common and total kit weight in listings ranges roughly from 0.75 lb up to about 3.35 lb.

Kits commonly include metric sockets from about 6 mm up to 13 mm and a mix of screwdriver bits (Phillips, flat, hex, Torx, Pozidriv) in standard lengths such as 25 mm and 50 mm. Some kits also include small HSS drill bits (for example, 1.5 mm and 2.5 mm).

Some kits explicitly include a rechargeable battery and charger (examples list 3.6V or 4V packs with chargers), while other listings state a battery is required but not included. A few items are USB-powered or include a USB charging cable instead of a dedicated charger.
