I have a Jeep Wrangler used as a toad, battery would run down after multiple days of towing. I installed the battery charger, and it seems to work as advertised. I haven’t made a multi-day towing trip yet, but from the status lights, it indicates it’s doing what it is supposed to do. I installed this myself. It was relatively easy, my biggest “problem” was grafting the ground into my 6 pin connector. Had to make a pigtail, to get two wires into one hole. Just to make it harder on myself, I chose to solder my connections, and some shrink tubing and electrical glue tape, and finished it off with dielectric grease, as I found some early signs of corrosion. Good product, seems to do what it says, pretty easy install for a DIYr.
