Keep in mind that the QUALITY of a/c power that comes out of an inverter can range from clean to extremely "dirty". You get what you pay for. Some sensitive electronics require what is called a "sine wave" inverter. These are pricey, but will not harm sensitive equipment. Some computers and printers might require a sine wave inverter. I think the factory unit had the receptacle at the rear of the console, but that's not necessarily where the inverter is. Inverters produce heat and require proper ventilation. You can get plug in ones (cigarette lighter) up to about 400 watts. Above that and they require direct wiring, as they would exceed the current limit on the cigarette lighter circuit.
