Review on 🔌 Enhanced 4 in 1 Charger Outlet Socket Panel: Dual QC 3.0 12V USB Power Outlet, Car Voltmeter Gauge, Cigarette Lighter Socket & ON Off Rocker Toggle Switch for Car Marine Boat RV Truck (with Wire) by Gotdat Burton

Excellent customer service, quick response to all your questions. Use the main bezel as a template to place your design on the back, drill or cut holes, fit the bushings through the bezel into the base plate, secure the bushings to the back with large plastic nuts. Install the wiring using the included pigtails, apply 12V positive and negative to a switch that turns all outlets on and off and you're done. Excellent quality, I installed it on my boat to be able to charge USB phones, provide a 12V socket for other accessories and control the battery voltage.
