Battery/ inverter question?
So I am new to this. New to me, OLD RV. I've just been fixing it up and I am almost finished. I bought a little "cigarette lighter" inverter. It works fine in my car. But when I put it in the RV (...

I have a small coffee grinder that I bought specifically because it is only 70 Watts @ 120V. Rather than start up the generator first thing in the AM, I have an inverter that is appropriately sized. In two different RVs there was not enough power to operate the grinder. Simply put, if the gauge of the wire from the source to the 12V outlet is too small, the resistance will cause a voltage drop and the inverter will give you a low voltage warning. From what I have seen, the outlet can only handle charging a phone, tablet or small notebook computer. Lucky for me, there was a power port in the dash of the Sprinter connected to the chassis battery capable of running an inverter with a load up to about 150 Watts @ 120VAC. For any inverter to function correctly, it should be hard wired directly to the source with wire gauges appropriate for the distance to the inverter.
