The 21W rollable is the perfect portable solar solution for waterlogged environments when you need to keep medium electronics powered-up or you want to supply a trickle charge to the battery of a boat without worrying about the water. Unlike other thin-film solar technologies, PowerFilm solar chargers do not need to be "sun soaked" after storage to produce peak power; you have critical power to moment you need it.
How the charger works:
Place the charger solar-side up in the sun.
Connect the charger using either the female CLA or 15' O-ring terminal extension cord (both included) to your device or 12V battery.
Note - unlike the USB+AA and AA solar chargers there is no storage mechanism, meaning the charger will only produce DC power while in the sun.
