Solar battery system
I tested a solar battery system.
PowerFilm, 14 WATT R-14, Rollable Solar Charger
It is flexible and waterproof.
powertraveller, MINIGORILLA, Lithium Polymer Rechargeable Battery, 9000 mAh
It can be charged by a solar panel, and has multiple output voltage: 8.4/9.5/10.5/12/16/19v and USB 5v.
