Review on 🔌 4 in 1 Charger Socket Panel with LED Voltmeter, 12V 4.2A Dual USB Charger Socket Power Outlet, Cigarette Lighter Socket, and LED Lighted ON Off Rocker Toggle Switch for Car Marine Boat RV Truck by Bernard Her

I bought this knowing I wasn't going to use a switch or plate. I installed a USB voltage sensor and a 12V cigarette lighter socket in a switch panel I made for my truck. The pressure gauge is ok. I've noticed that the voltage doesn't always match what the battery and yard indicated, but it's always within 0.2-0.3 volts. The USB charging port works well and wiring is easy for both ports. On the back of each connector is a + or - sign to indicate how it is connected. Overall I would give the product a 3.5 out of 5 as the connectors provided are cheap and the connectors and sensor are a bit long to fit in a tiny area. I would recommend this to anyone looking to add a voltage sensor or charging ports but want better electrical connections.
