Detect live voltage in two seconds without touching the wire by bringing the device near it; a touch-activated side pad powers up the unit, and the LCD reports the reading in milliseconds.
Inside sits a sensitive induction coil. AC voltage creates a faint electromagnetic field around live conductors, and the VoltSpark detects it without any contact through insulation, drywall, or closed boxes. The display uses red to indicate live and green for neutral, with voltage values shown on the digital readout up to 450V, covering common household, mains, and light industrial ranges.
For multitasking on the job, VoltSpark combines a 2-in-1 bit (flat and Phillips) in the same shaft, letting you test a wire and drive a screw without swapping tools.
Break-Finder Mode lets you scan a cord to locate breaks; the display shows 0 when the line is intact and oL (silent) when the cord is broken.
Activation is touch-based: press the side pad with your thumb to wake the device; the color readout appears instantly, removing guesswork about live or neutral.
Compact and pocketable, VoltSpark rides in a pocket with a clip and comes in two color options: red or black to suit your kit.

What DIYers and Pros Are Saying
"Bought this after getting shocked twice by old testers giving false negatives. This one’s dead accurate so far. The screwdriver tip is a surprisingly handy bonus — replaced the cheap one in my pouch." — Mike T.
"Found a break in a 50-foot outdoor extension cord in about 30 seconds thanks to break-finder mode. Would have tossed the cord otherwise." — Dave R.
"Carries it in my back pocket every job. Battery’s still full after three months thanks to auto-off." — Alex K., journeyman electrician
Your next live wire shouldn’t be discovered by touch.
