I usually use slightly higher end name brand testers, but this is a well constructed unit with a clear backlit screen. The safety tip to protect the probe pushing through the case is a handy feature, and the sprung wire to the negative clip is sturdy. The small torch at the front isn’t strong but is extremely handy when you’re checking fuses in a dark car boot. A much better alternative to the screwdrivers with the bulb in the handles. ## Features - Smart Circuit Tester:It can recognize the current measured signal (DC voltage, polarity, resistance, and continuity)automatically once the probe touched the power supply or resistance under the default smart measurement mode. Then you can press the hold button to read the results on the screen. It needs no extra operation. - Wide Test Range: The power circuit probe has a wide detection range from 0.8v-100v DC, which is suitable for various vehicle circuit tests like car fuse testing, wire checking, battery and ACC system testing. It makes easier for you to check the problem of vehicle. It can also automatically identify the positive and negative terminals of the battery, and the "-" sign before readings means negative. - High Accuracy Car Fuse Tester: The car DC voltage circuit tester has a resolution of 0.001V resolution under 2V voltage while the resolution is 0.1V under 100V voltage. The resolution of resistance is range from 1Ω-0.01MΩ while the resistance is range from 2000Ω to 20MΩ. The accuracy is about ±1%. - Friendly to Use: The OBDResource smart circuit tester for car has an data hold on button, which can make the data on the screen unchanged for recording. Also the inner buzzer can remind you if the resistance is below 50Ω. Or if the DC voltage is higher than 100V, the screen will shows "OL". Furthermore, the long spring has a negative clip and probe head cover, so you can operate and store it individually and safely. - Backlight LCD Display and More :The voltage tester pen for car equipped with a backlight LCD display and flashlight for a clearer reading and precise operation in dark place. You can press light key shortly to turn on/off the screen backlight and long press it to turn on/off the flashlight. The storage bag in the package makes it convenience to store when it is spare. We also offer you a 1-year guarantee. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0CMZ8R5CK | | Best Sellers Rank | 131,501 in DIY & Tools ( See Top 100 in DIY & Tools ) 145 in Circuit Testers | | Brand | OBDResource | | Colour | black | | Country Of Origin | China | | Customer Reviews | 4.5 out of 5 stars 275 Reviews | | Included Components | Circuit Tester | | Item Dimensions | 17.5 x 2.5 x 2.6 centimetres | | Item Weight | 0.14 Kilograms | | Item dimensions L x W x H | 17.5 x 2.5 x 2.6 centimetres | | Item weight | 0.14 Kilograms | | Manufacturer | OBDResource | | Manufacturer Part Number | CC0176 | | Maximum Operating Voltage | 100 Volts | | Measurement Type | Voltmeter | | Minimum Operating Voltage | 0.8 Volts (DC) | | Model Number | CC0176 | | Number of Items | 1 | | Power Source | Battery Powered | | Power source | Battery Powered | | Specification Met | CE, EN 61010-1 | | Style | Electrical Circuit Tester | | Style Name | Electrical Circuit Tester | | UPC | 747302355215 | | Unit Count | 1.0 count | ## Product Details - **Brand:** OBDResource - **Colour:** black - **Item weight:** 0.14 Kilograms - **Power source:** Battery Powered - **Style:** Electrical Circuit Tester ## Images ![Car Smart Circuit Tester, 0.8-100V DC Voltage Tester with Flashlight - Image 1](https://m.media-amazon.com/images/I/61QsPtJfi9L.jpg) ## Available Options This product comes in different **Size** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ battery tester *by R***O on 10 April 2025* great piece of kit does the job and easy to use,usful bit of kit ### ⭐⭐⭐⭐⭐ Good voltage tester *by Z***N on 20 October 2024* For £13.50 this is a bargain. I usually use slightly higher end name brand testers, but this is a well constructed unit with a clear backlit screen. The safety tip to protect the probe pushing through the case is a handy feature, and the sprung wire to the negative clip is sturdy.

A much better alternative to the screwdrivers with the bulb in the handles. ### ⭐⭐⭐⭐ Easy to use *by R***N on 6 February 2026* As described, prompt delivery, easy to use, clear display, useful cap for probe, led light is weak but better than none. Storage pouch keeps tester tidy in tool kit but it is a snug fit. There is enough room in the case to store a AAA battery separately either as a spare or to prolong battery life. Reasonable price. ## Frequently Bought Together - OBDResource Car Voltage Smart Circuit Tester, Power Circuit Probe 0.8-100V DC Voltage Tester Automotive Continuity Test Electrical Tester Car Fuse Tester with Flashlight for Car Battery - JOREST 300Pcs Car Fuses Assorted Kit, 160 Mini Blade Fuses Automotive + 90 Standard Mixed Fuses + 50 Micro Fuse Set + Fuse Puller – for RV Truck Motorcycle(2Amp 3A 5A 7.5A 10A 15A 20A 25A 30A 35A 40A) - ZKTOOL Power Circuit Probe, Automotive Electrical System Tester DC 6-24V, Car Circuit Tester, Short Circuit Tester, Voltage Tester, Polarity Identify, Test Light, Component Activation --- ## 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.tw/products/587735724-car-smart-circuit-tester-0-8-100v-dc-voltage-tester](https://www.desertcart.tw/products/587735724-car-smart-circuit-tester-0-8-100v-dc-voltage-tester) --- *Product available on Desertcart Taiwan* *Store origin: TW* *Last updated: 2026-09-17*
