Review on 🌞 SunJack 15W Portable ETFE Monocrystalline Solar Charger for Cell Phones, Tablets - Waterproof, Foldable for Backpacking, Camping, Hiking & More by Joel Gumbiner

Revainrating 4 out of 5

Good price but a little heavier than expected

My external battery fully charges in about 6 hours in the California sun. Functionally almost perfect. However, I want to step into an ultralight backpack and it seems about 8 ounces heavier than I would like. I can keep looking for something lighter but just as useful.

Pros
  • Comfortable
Cons
  • Having trouble
