The Lixin 2 pin adapter is a well made product using 10 gauge wire. It fits perfectly into the Furrion solar charging port on my Forest River RV (I checked the connection with my volt/ohm meter). Combined with a 20ft two-prong extension cord, this allows me to use my suitcase's solar panel to charge the battery during dry hikes. I think it's good that an adapter for reversing the polarity is included. I look forward to using it this summer. The price was very competitive compared to actual Furrion gear.
