This multifunctionvoltage tester penquickly checks whether a wire or circuit has power and helps you accurately find line break points using bright LED indicators 😍. As you slide the pen along the wire, the green LED stays on where the line is intact and turns off at the exact position of the break, making fault finding fast and simple 🙌.
The tester supports AC voltage detection (typically 12–300 V depending on model), live/neutral identification, continuity checks, and basic on/off judgment, all in a compact pen‑style body ✨. A built‑in high‑brightness LED and sound/light alarm ensure clear indication even in bright rooms, while the pen clip design lets you carry it in your pocket or tool bag with ease 👨🔧.
Perfect for electricians, DIY users, and home maintenance, it is ideal for checking sockets, switches, extension leads, appliance cords, and holiday lights without cutting the cable or stripping insulation 🏠. The insulated tip and intelligent circuitry help improve testing safety, but normal electrical precautions and local safety standards must always be followed ⚠️.
