When you shop for electrical testers, a pocket voltage pen is a handy first tool. Two pen-style detectors look similar at a glance: one catches AC and DC from 12V to 1000V, while the other focuses on AC from 90V to 1000V and announces live circuits with a beep. Both are new, non-contact pens with U.S. origin. The decision comes down to voltage range, feedback style, and the kinds of electrical checks you actually do.
Quick verdict: Choose the Voltage Electric Tester when you need to trace low-voltage DC circuits, want a readable display in dark spots, or prefer a self-checking tool. Choose the Electricity Test Pen for routine AC outlet checks where a red glow and an audible beep are more useful than a wider range.
| Product | Price | Price Bar | Detection Coverage | Feedback & Extras |
|---|---|---|---|---|
| Voltage Electric Tester 12-1000V | USD 4.29 | 12-1000V AC/DC | Digital display, self-check, screwdriver tip | |
| Electricity Test Pen 90-1000V | USD 3.20 | 90-1000V AC | Red glow plus beep, 50-500 Hz |
Where the Voltage Electric Tester wins
- Detects both AC and DC, so it doubles as a low-voltage checker.
- The detection floor starts lower, so smaller circuits are within reach.
- Blue-ray digital display stays readable in the dark.
- Self-check function plus null-line and broken-point detection.
- CR-V flatted screwdriver bits give the tip a dual-purpose edge.
Where the Electricity Test Pen wins
- Costs less than the other pen in this comparison.
- Non-contact tip glows red and beeps when voltage is present.
- CAT II 1000V safety rating noted for AC work.
- 50-500 Hz frequency coverage matches typical wiring.
- Battery-powered design keeps it simple, with 2 AAA batteries needed (not included).
Voltage Electric Tester Volt Detector Test Pen AC DC Non-Contact Sensor 12-1000V
The broader tool of the two: it reads DC as well as AC, so it fits electronics work alongside household checks. The blue-ray digital display is described as easy to read in darker environments, and the self-check function helps you confirm the pen is working before you trust it. It can also distinguish the null line and find the broken point, which is handy for fault-finding in wiring. The insulating ABS shell and CR-V flatted screwdriver bits add practical value. The feedback is visual, delivered through the display and indicator glow. If you want one tool that covers both AC and DC duty without switching, this is the one.
Electricity Test Pen Digital 90-1000V AC Voltage Detectors Non-Contact Tester Pe
The focused AC option. It targets terminal strips, outlets, and supply cords, with coverage across the AC range found in everyday electrical work. Touch the tip to a conductor and the unit glows red and beeps, giving audio confirmation that is easy to act on. The CAT II 1000V safety rating and 50-500 Hz frequency range align with standard AC environments. Keep in mind the starting threshold sits higher, it reads AC only, and it needs 2 AAA batteries that are not included. There is also a California Prop 65 warning. For quick, audible checks of standard AC circuits, this pen gets the job done with a simple, direct approach.
Final choice by use case
- Low-voltage electronics or DC circuits: choose the Voltage Electric Tester.
- Standard AC outlets with audible confirmation: choose the Electricity Test Pen.
- One tool for AC and DC across a wider range: choose the Voltage Electric Tester.
- AC-only work with minimal fuss: choose the Electricity Test Pen.
