Before you touch an outlet, switch, or wire, you want to know whether it’s live. A non-contact tester pen tells you in a second.
I tested the Proster Non-Contact Voltage Tester Pen on outlets, a light switch, and even a wall in my home.
In this non-contact voltage tester pen review, I’ll cover how it alerts you, sensitivity modes, the flashlight, batteries, and my tests, the pros and cons, and who it’s for.

What Is the Proster Voltage Tester Pen?
The Proster Voltage Tester Pen detects AC voltage without contact and warns you with a beep and flashing LEDs.
Key Features
- Non-contact AC detection: 48-1000V by default, 12-1000V in high sensitivity
- Audible beep and LED alerts
- Hot vs neutral detection at close range
- Built-in LED flashlight
- Auto power-off and low-battery indicator
- 2 AAA batteries included
- Pocket clip, ABS and PVC body
Testing Outlets
When it senses voltage in an outlet, it starts beeping. You can test either the hot or the neutral side and hear the difference. The LED lights flash to show whether it’s picking up lower or higher voltage.
Sensitivity Modes
One button switches sensitivity. When the icon lights up, it’s in the more sensitive 12-1000V mode. Turn that off, and it detects 48-1000V.
The Flashlight
I like the little flashlight, which lights up the area you’re working in.
Light Switch and Wall Test
I tested a light switch and could see it had voltage running to it. Then I ran it along the wall, and it beeped. There’s an outlet below, so a cable runs up through that wall, and it picked it up through the drywall.
Batteries
It comes with two AAA batteries. Just pop them in, screw on the cap, and it’s ready.
Things to Consider Before Buying
- AC only: It detects AC voltage, not DC.
- Confirm before work: Always turn off the breaker and double-check with a meter for serious electrical work.
