Product is junk and customer service sucks
I purchased a Blackout Buddy as a backup for my refrigerator. It repeatedly had error codes and the outlets quit working within 6 weeks. Totally unreliable. I contacted the company to return it and the solar panel I purchased. They charge a "restocking fee" of $50 to return the panel and $100 for the Blackout Buddy plus return shipping was on my dime. I'm out $250. I warn people NOT to buy from this company.
