The Redarc In-Vehicle BCDC Battery Charger - Dual Input - DC to DC - 12V/24V - 25 Amp # 331-BCDC1225D is primarily for people that want to ensure they have full and maintained batteries when they get to their campsite. Without a strong enough DC to DC charger, the larger battery banks barely get a charge while traveling, so they are not adequate for shorter trips or longer stays with battery power. These are really great options for people that want to camp off the grid and they can also add solar for prolonged stays. The 20 amps is a significant power boost from the roughly 2 amps that are gained without a DC to DC charger so it significantly increases the charging power versus simply maintaining when towing.

It is ideal for campers who store their camper away from a maintainer and yet have a few hour trip to their camping destination and need battery power to stay. It is also great for trailers with multiple batteries.

I've attached a couple of videos to assist.
