Review on 🔌 Deyooxi 12V USB Outlet – 4-in-1 Marine Boat RV Truck Panel with Dual USB C Socket, LED Voltage Display, Cigarette Lighter Socket, and Toggle Switch – 12 Volt Power Outlet by Jake Solorzano

All these modules are interchangeable. I set mine up with 2x voltage indicators and 2x 12v sockets. The panel is very tight to cover the required holes for the modules. If you try to cut a square hole, you only have a fraction of an inch of error. I settled on a 1.5" hole saw, which still has a small installation error. I removed the modules from the mounting plate and traced where the holes should go, then drilled a 1.5" hole as close as I could get possible at the center of these marks This method has been successful, however any error in centering the holes is an obstacle and oversized holes will show up when inserting the insert as it does not cover the entire hole Plate looks good, is but difficult to assemble.Some of the larger panels have more room for error.The 5 button switch panel with three module slots had many more overlapping panels and was easier to install ensuring the mounting hole was covered.
