This item works exactly as advertised and is easy to install. It charges my batteries much, much faster than the archaic piece of junk it replaced. I also no longer have to worry about constantly having my RV powered and batteries ready, and (and that's a big plus) it delivers a very clean DC output, which is important when using multiple types of batteries want direct voltage to on-board devices such as a television. If you really want to take full advantage of it in any RV or boat with a home/starter battery setup and want to completely upgrade your system if it uses an isolator to separate them, replace it with the Blue Sea SI-ARC (Automatic Charging Relay ). To the shop. It costs almost as much as an isolator if yours fails (about $75), is even easier to install than a converter/charger, eliminates a 0.5-0.7V voltage drop from your alternator to household batteries and , more importantly, I think allows your charger to also charge the starter battery. Both modifications, especially when done together, are definitely a win-win situation!
