Review on Versatile 4-In-1 Charger & Power Outlet Panel With LED Display And Dual USB For Truck, Car, Marine Boats & RVs: GOOACC by Marcos Olvera

I am using this as one of several emergency power banks. This is attached to a plastic tool box in which I cut out enough to insert the GOOACC panel. This panel has everything you need: a switch to turn everything off, including the led panel lighting, USB sockets (2), volt meter and a 12V socket. Using this panel, the build can be used by my friend with an oxygen concentrator which has a short-lived battery, a ham radio, my dash cam during parking periods where the engine is shut off, and many other uses. I insert a lithium iron phosphate battery and the result is a very useful power system that can be used and recharged many times.
