Review on 🔋 12V Digital Voltmeter: DROK 0.56" DC 3-30V Voltage Tester with Bright Green LED Display, 2-Wire Volt Meter Detector for Solar Battery Monitor, Car Motor Panel Mount - Ideal for SEO by Nuntawat Bridges

I can confirm many positive reviews of this digital voltmeter. In a car with so many factory idiotic dashboards, this gauge is a very welcome addition. Installed directly on the battery terminals, it syncs perfectly with my Fluke test and reads fluctuations very quickly. The light is big and bright enough to read in any daylight. If you are using this in a car I suggest fitting an on/off switch or mounting the meter so that it is not pointing directly at the driver as it is very bright at night. I fitted a latching switch and am satisfied! I recommend this to anyone who wants to be up to date on the status/usage of a car battery.
