Sorry, Juan, solar ovens are crap. They don't work during rain, clouds or night; the net heating rate tends to be slow due to forced convection heat transfer to outdoor breezes; and some of the reflective surfaces used can concentrate short wave UV light onto the hands and eyes of the user.
Portable solar generators produce low voltage DC current which is efficient for charging communications equipment and batteries, and less efficient for running equipment requiring 110VAC power. They are best paired with equipment designed to use DC power, for example items designed for use in aircraft and some RVs.
