Abstract: A portable fleet management system enables an operator to efficiently manage a fleet of drones in the field. The portable fleet management system may a comprise a portable housing that houses a charging system for charging batteries of the drones, a storage system for storing images, video, or other sensor data captured by the drones, and various other control, input/output, and processing elements for enabling efficient management of a drone fleet. The charging system is beneficially configured to enable charging of multiple different makes and models of drone batteries that may have different form factors and charging requirements. Furthermore, the storage system may enable efficient offloading, processing, sorting, and backup storage of images or video captured by the drones.
