    Glitchy Junk
  

*by J***C on Reviewed in the United States on December 1, 2020*

Broke on day 3 of winter vacation at Zion National Park. I followed all the instructions and it worked when I tested it before I hit the road, however after a few days it broke and left me without the ability to safely charge my RV battery. Now I’m screwed stranded without any stores around... ugh.VERY DISAPPOINTING!!!!
