I bought these 100w panels to recharge my Delta Ecoflow 1300w solar generator and I am happy with my choice. With full sun, they are giving me 80 to 90 watts! Some people showing even 94 watts. I do have Ecoflow 110w panel and it is a more superior product but cost twice as much. These Rockpals are one of the best on a market, among foldable panels right now, regarding price and quality. I wish it would have an integrated stand to position them easily but for the price, I can manage that issue myself. Overall I am happy with this purchase
