Abstract: A card-style solar charger includes a flexible substrate, a solar cell, and a transparent cover membrane which are stacked up in bottom-to-top order and is characterized in that the card-style solar charger has an output end electrically connected to a connector of a transmission cable for supplying electric power. The card-style solar charger comes with different output ends to suit different contacts of a connector. Due to its card-like appearance and its way of generating solar power, the card-style solar charger is portable, lightweight, compact, easy to use, capable of instant charging, and widely applicable.
