Review on NOCO GENIUS10 Smart Charger - 10-Amp Fully-Automatic 6V and 12V Battery Charger with Temperature Compensation for Maintaining, Trickle Charging, and Desulfating Batteries by Brad Jeffress

Cool stuff! We got a new camper and didn't have our 50 amp mains installed yet, so we didn't have full power, only 12 volts. But we really wanted to stop in our new camper. We only had a 20 amp outlet and an extension cord available. To top it off, the dealer left the lights on in the RV and didn't turn off the 12 volt system, draining the battery. We pulled out an extension cord and connected this charger to the battery. It was powerful enough that we could run the oven, water pump, and any LED lights we needed inside. And in the morning the battery was almost fully charged! We spent a total of 4 nights in it and it is our main power source for all our 12 volt needs. I will buy a second set of clamps just in case. This way I can hardwire my RV battery and still have a set of terminals to plug into my daughter's car when she leaves the lights on (about once a month) 🙄.
