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 Shawn Jimenez

OK, as many have noticed, NO WIRING DIAGRAM. Although now - in the pictures of the product - there is. Here's the problem, there are 4 devices, all with a brass connector, and the rest are some other metal (called silver). And there is a sentence in the description that says the brass terminal on the switch is negative. It can be assumed that the other 3 devices will also have a brass negative terminal - for the sake of consistency. However, this is NOT the case - the other 3 have the brass connection positive. After an hour of hair pulling and four letter words, I began to suspect it. Also NO documentation. I finally found a youtube video that was 2-3 seconds long showing the brass clamp of the other three being positive. It would be SO EASY to put the appropriate symbol on the new schematic = but why make it so easy for the user? It's a shame because the product itself is very good. Sigh!
