The surge protector protects the entire trailer from the 30a 110v line at the RV campsite; it keeps power surges from getting to your power converter and tells you if the RV parks 30a outlet is good or bad before you ever plug into it. This protects all of the trailers voltage sources both 110v and 12v. This is not necessarily the one that I would recommend only the one that was priced within my pocketbook, the others cost over twice as much but I'm sure that they have more whistles and bells.
