My recent purchase of this digital voltmeter was a real game-changer in terms of monitoring the power supply in my car. My analysis of this product showed that it is very easy to install and can fit in any conventional cigarette lighter socket.It displays the real-time voltage of my car battery and ensures that I'm never stranded somewhere because of a dead battery. The only downside is that it doesn`t come with installation instructions, but that can be easily overlooked considering its amazing feature set..
