Jesscasday 100W Folding Solar Charger — Portable Foldable Solar Panel with 12V & 5V USB Outputs for Outdoor and Car Roof Attachment

100W Jesscasday folding solar panel designed for portable outdoor use and emergency power. The panel is flexible and foldable so it can conform to and be attached to smooth surfaces (for example, a car roof). It uses a new conversion method that doubles the working current of the solar output: with the same area and power, the two-way voltage output is switched into 18v and 9v or 12V and 6V by shifting gears, which effectively doubles output current, raises efficiency and speeds up charging. This approach makes it possible to charge car batteries, mobile phones and computer batteries under the same environmental conditions. Provides 12V output plus 5V USB output for charging mobile phones, tablets and other electronic devices.
