Electricians, DIYers, or anyone who tinkers with wiring – this voltage tester pen is a handy little tool to have in your kit. It can test AC voltage from 70 to 250V by direct contact and detect voltage from 70 to 600V without contact (just by bringing it near a wire). It also has a breakpoint detection feature: run the tip along a wire, and when the light goes off, you’ve found the break. The pen is waterproof (just dry it off if it gets wet), and it has a bright indicator light to show voltage presence. It’s about 140mm long with a 3.5mm tip, making it easy to carry in a pocket. Great for checking outlets, switches, or appliances to see if they’re live before you work on them. Remember: always follow safety procedures, and this tool is a supplement, not a replacement for proper electrical knowledge. A simple, affordable way to add a layer of safety to your projects.
