How a $100 Solar System Charges all my Electronics for Free

One foldable solar panel the size of a sheet of paper charges my iPhone, iPad, Chromebook, and VR.

  • The Li-ion batteries (each about the size of an iPhone) were $30 each.

One 21W solar cell adds more power every day than all of my devices combined can store.

Portable batteries rapidly charge from USB-C output. I don’t have to worry about plugging anything into a wall. I don’t worry about whether my devices are charged, and I don’t feel guilty about charging them.
