Abstract: A portable safe that includes a lower shell having a sidewall surrounding a bottom wall and defining an internal cavity and includes a cover rotatably and lockably coupled to the lower shell, wherein the cover has at least one photovoltaic cell directly coupled thereto and has a top surface defining at least one solar intake aperture exposing the at least one photovoltaic cell to an ambient environment and configured to convert solar energy to energy usable by the portable safe. The lower shell or the cover defines a cable aperture for receiving a cable that is operably configured to form a loop for surrounding a structural object. The safe has a locked position with the cable longitudinally retained by at least one of the cover and the lower shell and an article loading position with a portion of the cover removed from the lower shell and exposing the internal cavity.
