Review on 🚗 MICTUNING LED Digital Double Voltmeter: Round Panel Voltage Monitor Blue for Cars, Pickups, RVs, Trucks & Dual Battery Packs by Evan Roberts

I picked it up as part of my plans to redesign my RV's hull layout. I have a dual battery system with readings in the cab, but since I spend most of my time at camp in the back of a truck I needed a way to monitor the batteries. The Mictuning Dual Voltmeter is perfect for what I need. As you can see from the photos, at work I plugged it into the power bank we're using for testing and the readings are bright and easy to read. Setup is easy too. Rear 3 clamps, 2 silver 1 gold. Unlike most applications, the gold connector is grounded and shared between your two batteries or power supplies. The two silver clips are for the positive pole of any battery or power supply. I tested that both positive terminals are connected together and separately, compared them to my Fluke 400a meter and found the microphone setting to be very accurate. Fluke 400A AC/DC, 600V AC/DC TRMS Clamp Meter with frequency, temperature and capacitance measurements with NIST traceable certificate of calibration with data. It appears to be completely sealed except for a small opening in the back, so it should work great in the back of a truck where there's a chance it will be exposed to the elements.
