Review on 🔌 Nilight 4-in-1 Charger Socket Panel: USB Power Outlet, Voltmeter, Cigarette Lighter Socket, LED Rocker Switch; Ideal for Trucks, Cars, Boats, RVs; 2-Year Warranty by Clinton Delgado

The product contains everything you need. I removed all of the individual pieces and placed them in my own piece of aluminum with a diamond plate from Home Depot. I used a step drill to drill the holes. Added a 15A fuse for the 12V circuit. Leave individual backups for three devices. If I ever need to service them, I'll have to remove two screws and flip them over. This is an old 1952 Powerwagon and I had to charge my phone for security reasons. Works great so far. Easy to do. To do what I did you will need additional wires and spade connectors. I soldered some connections. It was a great way to add a 12v outlet, volt meter and two USB outlets. Love it.
