Dual-function Electrical Tester Pen — durable rubber body, voltage detection and magnetic screwdriver in one tool Key benefits Dependable durability: Constructed from high-quality, sturdy rubber for a long service life and resistance to wear in demanding conditions. Built to hold up during frequent professional use. Accurate AC/DC detection: Detects both AC and DC voltage with strong breakdown capability, providing reliable readings and safer decision-making before working on circuits. Comfortable, controlled handling: Ergonomic handle gives a secure grip and better control for precise testing and screwdriver work, reducing hand fatigue during extended tasks. Two tools in one: Functions as a voltage tester and a heavy-duty screwdriver, so you can confirm live circuits and perform repairs without switching tools. Faster, cleaner work: Magnetic screwdriver head captures small screws and metal parts for quick handling, preventing dropped hardware and improving workflow efficiency. Versatile and practical: Designed for professionals and hobbyists who need a compact, multi-purpose tool for diagnostic and repair work. What it does and why it helps Confirms live voltage (AC/DC) before you open panels or touch wiring, reducing the risk of accidental contact with energized parts. Serves as a robust screwdriver for fastening and loosening screws during installation or repair tasks, eliminating the need to carry a separate driver. The magnetic tip keeps screws in place so you can work in tight spots or overhead without losing parts, speeding up repairs and installations. Materials and performance Body: high-quality, impact-resistant rubber for added durability and grip. Functions: voltage detection for AC and DC circuits plus screwdriver functionality. Design: ergonomic handle for better control; magnetic screwdriver head for handling small metal parts. Typical applications Electricians verifying live circuits and then tightening terminal screws during maintenance or troubleshooting. Electronics technicians assembling or repairing devices where quick voltage checks and screw fastening are required. Homeowners performing basic electrical repairs, light fixture replacements, or appliance maintenance where checking voltage and using a screwdriver are both needed. Who should choose this tool Electricians, service technicians, repair professionals, and DIY enthusiasts who need a reliable, dual-purpose device that combines safe voltage testing with practical screwdriver use. Note: Keep standard safety precautions when testing live circuits. Use this tool as part of a safe work procedure.
