Abstract
Devices, systems, and methods may use a low current power source to charge an intermediate storage unit, providing sufficient electric power to perform various device functions. A voltage of the intermediate storage unit may be monitored using a voltage monitoring circuit, and a primary storage unit may be charged using current from the intermediate storage unit when the voltage of the intermediate storage unit meets a threshold.
