PowerFilm Solar launched a new product this week that’s another variation on the foldable, thin-film-based solar battery charger. The charger weighs less than 4 extra batteries and folds to pocket size. There’s only so much that can be said about solar-powered battery chargers, as there seems to be no shortage of offerings, but it should also be noted that this company is making a clear push to market their thin-film solar solutions to the military as well. Through their work as Iowa Thin Film Technologies, the company has a number of solar-powered tent products that are intended for on-site, off-grid military situations. A building-integrated section of their site is still under construction.For more information, see the following link.
