SunJack 15W Solar Charger Portable Solar Panel with USB for Cell Phones, Tablets for Backpacking, Camping, Hiking and More

Charges well for such a small panel. Does not need clear sky to work, which is useful in the uk.I use solar panels for ‘off grid’ van camping to avoid running down the vehicle battery I do have a much larger and heavier 120w ‘portable’ panel but the little Sunjack is just the job for quickly hanging up in the door between the showers which are a traditional part of our English summer.

i saw youtube reviews claiming 16w out of 25w from thie pannels,and i taught thats good enough, but the most i get is 10.4wso dissapointed, i should have bought the 15w smaller pannel instead since 10.4w is soo little for the size in my opinion
