Inverter out -- extension cord?

pianotuna, you are correct on A thru D. There is no loss when the inverter is off. However my responses to your posts have been based on your previous post, "It would be simpler by far to feed the plugs direct from the inverter and always have it on." Note, "always have it on". If I were to "always have it on" the inverter would always be drawing battery power when boondocking, even if the devices were off. This is correct is it not? I think sometimes the posts get lost when threads get so long. My main focus is only using battery power when it is needed. There is enough parasitic draw from the various other items in the 5er. no need to include an inverter if it is not being used all the time.
