First Look Looking at the unit you see how well it looks and some of the nice design features it has with the colour screen and the removable probe along with a massive 20ft extension cable. It has all the connections you need, Direct from the battery or from the included lighter socket adapter. First use The unit was powered by the lighter socket and booted up into the menu in a second. You are presented with a nice clear colour display and 4 menu options at the top of the screen. The unit has 2 led's on the top of it giving you some light to work with. You select the menu option with the round menu button on the device. The menu runs through the following settings DC Voltage, AC Voltage, Resistance and Diode Just press the menu button until you see the correct screen. With the probe in DC Voltage it allows you to read the DC Voltage of a circuit The AC Voltage does the same but for AC Voltage The Resistance mode enables you to check the resistance between the tip and the Aux ground Lead. In this mode you can check the voltage drop from positive to negative on a diode I used the probe to check a few headlight bulbs I had lying around not knowing if they were out or not. I connected the Aux cable from the probe to the negative on the bulb and touched the tip to the positive, this allowed me to check the circuit. The screen went green confirming no issues with the continuity of the bulb I then pushed forward on the toggle switch and applied voltage to the bulb lighting it up. A quick two-minute task is completed with the tester saving a lot of time and effort. My Thoughts, All in all a solid bit of kit with easy to use features and a easy to use menu. A Good design aesthetic and all stored in hard plastic case. a must for anyone who works on electrical systems. Review: Should have bought one of these years ago. - Love this tool! Really speeds up diagnosis.. love the fact that you can inject positive or negative feed down a wire by pressing a switch.. makes circuit detection instant! works on 12 or 24v so good on cars/vans and commercial HGV also.

Nice set of adaptors, well made and sturdy.. dont wait, just buy it.. will pay for itself in saved hours probably on the first job or 2! ### ⭐⭐⭐⭐ decent cheap tool *by C***S on 27 May 2021* As an Automotive professional brought this to replace my original power probe, thought it would be useful to display the different voltage on vehicles as opposed to just + & - V. Used everyday for last 2 weeks on approx 10 jobs per day and has performed fine, has 2 LED's that come on as soon as powered up that at first I found annoying but have to admit are quite useful, easy to probe into looms (beeps let you know when contact made). Only point I would make is having been a tech for many years tool does feel a bit cheap and lightweight, as opposed to just chucking this back in toolbox when finished I keep it out of the box on the dashboard of my van, and so far all ok I wouldn't think it would last long rolling about with other tools in a drawer, on the positive side leads are good quality and with the extension cable you could easily walk around an artic cab and trailer. ## Frequently Bought Together - KZYEE KM10 Power Circuit Probe Kit, 12V 24V Automotive Circuit Tester Electrical System Tool, Digital Voltage Tester, Short Finder, AC DC Diode Resistance Current Probe Tester, 20FT+20FT Cable - JOREST 300Pcs Car Fuse Assortment Kit, 160 Mini Blade Fuses Automotive + 90 Standard Auto Fuses + 50 Micro Fuse + 1 Puller – for Car/RV/Truck/Motorcycle(2Amp 3A 5A 7.5A 10A 15A 20A 25A 30A 35A 40A) - Heavy Duty 3-65V Backlit Digital LCD Circuit Tester, Test Light with 140 Inch Extended Spring Wire, Car Truck Low Voltage & Light Tester with Stainless Probe --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.hr/products/49958181-km10-power-circuit-probe-kit-12v-24v-automotive-circuit-tester](https://www.desertcart.hr/products/49958181-km10-power-circuit-probe-kit-12v-24v-automotive-circuit-tester) --- *Product available on Desertcart Croatia* *Store origin: HR* *Last updated: 2026-07-12*
