Review: Reliable, Easy-to-Use Voltage Tester — A DIYer’s Safety Net - I’ve been using the KAIWEETS Voltage Tester for months now, and it’s still going strong. The use is incredibly intuitive — turn it on and you’re ready to go. I’m not a professional, so being able to quickly check for voltage before working (see my photos replacing a single-pole light switch) gives real peace of mind. The features are well thought out. I like that you can increase sensitivity to detect current more easily, and the built-in light is genuinely useful — just hold the button for two seconds to toggle it on or off. Instructions were clear, which made ease of installation and setup straightforward. In terms of utility, this is perfect for DIY home projects, and the durability has proven solid after repeated use. It’s been accurate every time I’ve checked — roughly 50 uses so far with consistent results. Overall, a simple, reliable tool that helps keep you safe while working around electricity. Highly recommend for any homeowner or DIYer.
Review: Safety and precision in the palm of your hand - The KAIWEETS Non-Contact Voltage Tester is an essential safety tool for both DIY enthusiasts and professional electricians. The standout feature is the signal percentage display on the LCD, which provides much more clarity than a simple flashing light when pinpointing live wires. I love the dual-range sensitivity (12V/70V-1000V), allowing me to switch between standard home outlets and low-voltage systems like thermostats or doorbells. The wire breakpoint finder is a lifesaver for troubleshooting faulty extension cords, and the buzzer alarm is loud enough to hear in noisy environments. It’s well-built, intuitive to use, and provides the peace of mind needed when working around electricity.

## Features

- SAFETY FIRST: It will send out multiple alarms through sound and light. When the voltage is detected, the tip will send out red light and beep. When the higher the sensed voltage is, or the closer it is to the voltage source, it beeps at a higher frequency and the percentage value will be larger. At the same time, the screen will be red or green, red means high voltage and live wire are detected, green means low voltage and null wire are detected
- NON-CONTACT: With NCV inductive probe for AC voltage; Just place the tip near a terminal strip, outlet, or supply cord. When the tip glows red and the pen beeps, you know there's voltage present. The live wire detector can automatically detect the live or neutral wire. Ideal for breakpoint Test. Handy circuit tester for electricians, homeowners
- DUAL RANGE: Detects standard and low voltage (12-1000V AC / 70-1000V AC) for more sensitive and flexible measurements. Press the S button to adjust sensitivity and adapt low range for doorbells, thermostats, irrigation wiring etc.; The NCV sensor automatically recognizes the voltage and displays it on the bar graph, and the percentage value can display the voltage signal intensity more intuitively
- SECURITY LEVEL: IEC rated CAT III 1000V CAT IV 600V, Meets CE requirements; The electrical tester is safely double insulated. High Voltage Alert to warn you of voltage above 90V, the screen turn red and the safety symbol on the screen shines
- COMPACT DESIGN: Bright LED flashlight for work in dim ares; Low-Power-Indicator when battery voltage is below 2.5V; Automatic Power Off after 5 minutes without operation or signal detection; Pocket-sized, pen hook allows you to carry it in your shirt pocket. We provide 36-Month after sale service, Please feel free to contact us if you have any concerns

## Questions & Answers

**Q: Will this work through drywall?**
A: I just tried a few walls near light switches where I knew there was elec wires with switches on. The meter would register about "1 line high" near the wires BUT it would also cause the meter to blink the same on places on the wall where there was absolutely no elec wires! I did the test both using the regular setting and also the Supper Sensitive setting. So MAYBE it MIGHT give you some idea where the wires are, but doubtful since there are to many false readings to be sure. That said, this meter works great if you are taking readings without sheetrock blocking it.

**Q: would you recommend this over other models and why?   what do you NOT like about it?  how accurate is it?**
A: I like that it is louder than others, equally easy to use, and the price was good

**Q: I believe a wire that goes from my speaker passenger side rear door is dead, would I be able to use this to test the wire to see if there's power?**
A: You. Will need 12v tester

**Q: Do i manually switch from "lo" to "hi"? pressing the green "sensitivity" button on mine does not switch to "hi".**
A: Mine does not even turn on.
