Keep your essential gear charged up anywhere there's sunlight with this Solar Laptop & Phone Charger from Preppi. It has a compact form that's roughly the size of an iPad when folded up, with a high-efficiency solar panel built using a premium, Japan-made ETFE layer that supports superior clarity and bright light transmission, while also boosting durability and corrosion resistance. USB-A and USB-C ports provide charging for a wide range of gadgets, and its ability to harness 90% of the light spectrum between 350 to 1100 NM to power the solar cells makes it highly efficient.
