Flexible solar panel with SUNPOWER cells with a power of 7.5 W – 1.5 A for recharging devices (e.g. smartphones, GPS, tablets, etc.). Front pocket with USB controller. Practical internal pocket for 13” notebooks. Padded back created with O-range technology which makes it more rigid, ergonomic and breathable. Soft and ergonomic heat-sealed shoulder straps, mounted with original screws that allow easy replacement. Product washable by hand at 30° C.
