Problems with Renogy 20amp DC-DC Charger.
Perfect timing of this thread. I also have a 20 amp Renogy that’s not working. I’ll do the same test. I’m on my way to Alaska and want it working for those extended rainy days
As for Drew’s question, we’re told the dc to dc charger is easier on the alternator and will provide the proper charging curve for batteries. I have 3 methods of charging my batteries when not hooked up to shore power, which is most of the time for us. In order of preference, solar, dc to dc, and generator. Most of the time solar is sufficient and I hate running a generator in a campground. On extended cloudy days, it’s a good option for charging batteries while traveling between campgrounds. I don’t need it most of the time but for $100, it’s the cheapest backup.
