Review on Nilight 2 Pack Waterproof Car Cigarette Lighter Socket Adapter - 12V Power Outlet Replacement for Marine, Motorcycle, RV, ATV - Terminals Wires & Screws Included (2 Years Warranty) by Jeremy Meza

Simple assembly, cut a hole in the side of the screw on the support ring for support, screw the front panel to the optics and carry the fuse box. Easy, probably 15 minutes setup for both together. Then I plugged in my cooler and found that the outlet was large. I thought maybe my radiator plug was just unplugged. Unfortunately, not all of my 12-volt plugs are so sloppy that they come loose on the road or fall out of the socket off-road. I've seen duct tape added to make the connectors thicker and they seem to be holding up so far, but I would prefer the connectors didn't require duct tape or spacers to begin with. Great clean idea and setup but cannot recommend the base size for this reason.
