Measured it against a standard VOM, and was within .05 bolts of the VOM. Excellent results. Now I can check on my battery levels at night to see if I need to switch back to the utility or I need to go crank the generator. Some complain about the small wires. They are 22 gauge wires which are now industry standard for most all of your instrumentation wiring. It works excellent. Voltage is very accurate. I bought two , one is a backup. Review: Low price, not waterproof, works good - So far its GREAT. I did tape around the clam shell joint and silicone it, along with the hole for the wires. Just trying to prevent water getting inside. I also used a sharpie to color over the lettering on the outside of it. I wanted it all black. ## Features - Product content: you will receive 2 pieces voltage gauge meters, enough quantity to satisfy your daily use requirements, bring convenience to your daily life - Multiple purposes: the LED display voltage meter is applicable for most vehicles, like cars, ships, RV, substation automation, distribution automation, test equipment and so on, practical enough to satisfy your a plenty of needs - DC 4-28V car digital voltmeter gauge: two wire voltage detection; No separate power supply is required; Mini size with 3 digit LED digital display; Simple connection, easy to use and waterproof - Extreme working conditions: working temperature below zero 10 ℃ to 70 ℃; Working humidity: 10 to 80% (no condensation); Working pressure: 80 to 106 kPa; Sunlight exposure: no direct exposure; Do not exceed the specified value of this product during the measurement process to avoid damage to the product - Working voltage: DC 4-28V; Display voltage: 5-28V, real-time control of battery voltage status, bringing convenience to you ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B08TBVTCRK | | Best Sellers Rank | #16,893 in Automotive ( See Top 100 in Automotive ) #9 in Automotive Voltmeter Gauges | | Brand Name | Frienda | | Customer Reviews | 4.5 4.5 out of 5 stars (934) | | Included Components | 2 x LED digital voltmeter | | Manufacturer | Frienda | | Material Type | Polycarbonate (PC) | ## Product Details - **Brand:** Frienda - **Manufacturer:** Frienda - **Material:** Polycarbonate (PC) ## Images ![2 Pieces DC 4 to 28V Car Digital Voltmeter 12V Voltage Meter Car Audio Gauge LED Display 12V Waterproof Voltage Gauge Meter for Motorcycle(Green Light) - Image 1](https://m.media-amazon.com/images/I/41rWDGVDmYL.jpg) ## Available Options This product comes in different **Color** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ The white LEDs are nice and bright *by K***L on November 5, 2025* I got the white LED so that I could put it on a pole outside my solar battery bank. Measured it against a standard VOM, and was within .05 bolts of the VOM. Excellent results. Now I can check on my battery levels at night to see if I need to switch back to the utility or I need to go crank the generator. Some complain about the small wires.

I did tape around the clam shell joint and silicone it, along with the hole for the wires. Just trying to prevent water getting inside. I also used a sharpie to color over the lettering on the outside of it. I wanted it all black. ### ⭐⭐⭐⭐⭐ Simple - Accurate - Durable *by N***N on January 18, 2023* Great little voltmeter. I purchased these in a 2 pack. Nice large bright green display with 1-digit accuracy. I mounted one of these on my motorcycle to monitor my stator charging voltage. I am able to easily see the readout even on a bright sunny day. Hookup is simple there is just a positive and negative wire to connect. The display takes about a second or two to initialize. The displayed voltage is accurate, I verified and compared it with a quality DMM. Housing is a nice solid plastic. I mounted the meter with 3m tape and it holds securely. These voltmeters could literally be used to monitor voltage for any 6V or 12V system. The attached wires seem to be around 20 gauge or so and are about 36" long. Great little voltmeter. --- ## 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.co.za/products/296509029-2-pieces-dc-4-to-28v-car-digital-voltmeter-12v](https://www.desertcart.co.za/products/296509029-2-pieces-dc-4-to-28v-car-digital-voltmeter-12v) --- *Product available on Desertcart South Africa* *Store origin: ZA* *Last updated: 2026-05-11*
