Abstract: Consumers carry battery powered devices whose battery power depletes over the course of a day. Consumers do not always have access to a charging device or outlet to replenish their device's battery but are able to access sunlight or moonlight. By wearing one device that is powered by solar energy and moonlight energy and comprises watch functionality, key fob capabilities, personal identification, and digital capabilities, a consumer can also reduce the number of devices they need to carry without worrying about draining the device's batteries.
