Power Screwdrivers

Choose cordless for portability and work away from outlets; pick corded for continuous power and no battery swaps. Consider job duration, access to power, and whether variable speed or torque settings are needed

Light assembly and electronics typically need low torque (under ~10 Nm) and moderate RPM; general DIY and furniture assembly benefit from mid-range torque (10–30 Nm); heavy-duty fastening or drilling requires higher torque and variable speed. Look for models with adjustable torque/clutch to prevent overdriving screws

Lithium-ion batteries are preferred for higher energy density, lower weight, and minimal memory effect; capacity (Ah) and voltage determine runtime and power — higher voltages and amp-hours yield longer, stronger performance. Also check charger speed and whether batteries are interchangeable with other tools you own

Verify the chuck or bit holder type (hex 1/4" is common) and whether common bits are included or sold separately. Look for magnetic bit holders, a range of driver bits, a case for storage, and compatibility with specialty bits for Phillips, Torx, square, and Robertson screws

Lifespan varies with build quality and usage; regular maintenance includes keeping vents clear, charging batteries per manufacturer guidance, replacing worn bits, and storing in a dry place. For corded tools, inspect the cord; for cordless, monitor battery health and replace cells or packs when capacity noticeably drops

Look for models with a clutch to prevent over-torquing, variable speed triggers for better control, a forward/reverse switch, and an ergonomic grip to reduce hand strain. LED work lights and locking switches can improve safe operation in low-light or prolonged tasks

Entry-level/basic cordless models commonly fall under $50, mid-range units with better batteries and features are often $50–$150, and high-end or kit bundles can be higher. Consider overall bundle value, warranty, and battery inclusion when comparing prices
