How does it work when you're running off a power bank, then you get to a campsite that has power? is it a transformer, converter, etc? and how does it happen. Does it automatically changer from battery power to 110?
I've tried to wrap my head around this, but for some reason I cant seem to get it to click, I'm usually good at ac, or dc wiring, but mixing the two has me perplexed.

I am new and grappling with all that understanding too, so I await the replies! ha

It would be helpful to know if you are asking about particular hardware you already have (describe it) or if you are asking in order to decide how you wish to proceed. There are a bunch of different ways to go about it.

well, all my trailer has, is a breaker box, the rest has been stripped from the camper. I'm not sure what I'd need though. I thought about putting a battery bank in it for rustic campgrounds. but would like the option of charging the battery bank when using it, (like when we're at a hook up campground)

A brief answer is there are many different type of units in RVs, some just supply 12 volts to things that need 12 volts to operate, some also charge your RV battery, some systems automatically take over when plugged into a shore line (110) supplying the proper power to everything as needed. To my knowledge most newer systems are automatic. But it all depends on what you have and the design of your trailer. In days gone by a lot of trailers had two systems, one 12 volt one 110 volt and when you plugged in to a shore line you powered up your 110 items and you charged your trailer battery. Then systems was developed that when plugged into 110 the battery was charged but the system supplied constant voltage to all 12 volt items, many of these didn't even require a battery. So as you can see there is no single answer to how a given system works without knowing exactly what you have or desire to have. Also the dollars you wish to spend pays a part in what type of system you use if you are starting from scratch. If your trailer is equipped with two separate systems you will most likely only find a breaker box for the 110 and possibly a positive and negative wire that went from the battery to the 12 volt items. Hope this helps
