The ReVolt® Non-Contact Voltage Tester uses an integrated sensor to detect the electric field around compatible energized AC wiring without requiring contact with an exposed conductor.
Switch ReVolt® on and bring the sensing tip close to an outlet, cable, terminal, switch, or wire. When compatible AC voltage is detected, the red indicator flashes and the audible buzzer activates, giving you an immediate warning.
For breakpoint checking, move the tester gradually along an energized AC cable. A point where the voltage indication disappears may help narrow down the location of a possible interruption.
The built-in white LED flashlight can also be activated when inspecting darker or difficult-to-see spaces.

Meet ReVolt® Non-Contact Voltage Tester—a compact electrical tester designed to detect nearby AC voltage without direct conductor contact, alerting you with a flashing red light and audible buzzer before you begin electrical work.

As seen on:


Electrical voltage isn’t something you can see—and guessing around outlets, switches, cables, or wiring can put you at unnecessary risk. ReVolt® detects nearby AC voltage without requiring exposed conductor contact, giving you a fast visual and audible warning when voltage is detected. Bring the sensing tip close to the electrical point you want to check. If AC voltage is present within its detection range, the tip flashes red and the buzzer sounds.
A damaged or interrupted wire can leave you wondering exactly where the problem starts. Move ReVolt® gradually along an energized compatible AC cable or wire. When its voltage alert stops, it can help you narrow down the possible location of a break or interruption.

CHECK MORE THAN JUST WIRES. 🏠
ReVolt® is compatible with a wide range of AC electrical points, including wall outlets, switches, power cords, cables, wiring, terminal strips, lighting equipment, and other compatible electrical fixtures. ReVolt® gives you one compact tester for multiple everyday electrical checks.

Electrical work often happens exactly where visibility is worst—behind furniture, inside cabinets, near panels, or in dim corners. ReVolt® includes a built-in white LED flashlight, giving you extra visibility while inspecting hard-to-see areas.

The pen shape makes it convenient to carry around. I like having it nearby when checking switches and cables at home.
Alyssa D. 5/5 Verified
Compact and easy to keep in my toolbox. I still verify properly before electrical work, but useful siya for an initial voltage check.
Marlene C. 4/5 Verified
Tested it around a few known live outlets and the alert was straightforward. Nice that there's no need to touch an exposed conductor.
Rogelio P. 5/5 Verified
The built-in flashlight is useful in darker areas. Medyo basic lang but it does help when looking behind cabinets.
Warren M. 4/5 Verified
Good for quick checks around switches, cords, and compatible AC wiring. Mas convenient than guessing whether something might be energized.
Romeo C. 5/5 Verified
The sensing tip is easy to position near outlets and wires. Hindi complicated gamitin once you understand what it's designed to detect.
Hector V. 5/5 Verified
Very lightweight and the pen-style body is comfortable to hold. Good addition to my household tool kit.
Priscilla A. 5/5 Verified
Flashlight seemed like a small feature at first, but I've actually used it several times. Helpful when checking behind furniture.
Arnold F. 5/5 Verified
Useful when I want a quick indication before doing further testing. The light and buzzer response is simple to understand.
Liza E. 5/5 Verified
I like getting both a sound and flashing light when voltage is detected. Makes the indication hard to miss.
Diana L. 5/5 Verified
Small enough to fit in my work bag without taking up much space. Simple tool for quick checks.
Joyce B. 5/5 Verified
The flashlight helps when I'm checking outlets in dim corners. Simple feature but surprisingly practical.
Charlene J. 5/5 Verified
I used it along an energized cable while troubleshooting and it helped narrow down where the signal changed. Convenient little tester.
Nelson G. 5/5 Verified
Detection can vary depending on how close the tip is, so it took me a little practice. Once I got used to it, okay naman.
Douglas H. 4/5 Verified
Straightforward tester for basic troubleshooting. I always confirm the circuit is de-energized with appropriate testing before touching conductors.
Gwen O. 4/5 Verified
Bought this mainly for checking extension cords and wall outlets. The audible alert is loud enough for my needs.
Camille N. 4/5 Verified
I keep this in the same box as my screwdrivers and electrical tools. Doesn't take up much room and is easy to grab.
Freddie K. 4/5 Verified
Used this while troubleshooting some household wiring. It helped me narrow down which areas had detectable AC voltage.
Claudio S. 4/5 Verified
Works well for basic voltage-presence checks. I still treat every wire cautiously and confirm before touching anything.
