1. An apparatus comprising:
at least one solar panel coupled to a foldable housing;
at least one battery coupled to the housing; and
charge control circuitry electrically coupled to the at least one solar panel and the at least one battery, the charge control circuitry configured to control power flow from the at least one solar panel to the at least one battery based on one or more predetermined characteristics of the at least one solar panel, wherein the charge control circuitry comprises first input circuitry for charging the at least one battery from the at least one solar panel and second input circuitry for charging the at least one battery from an external power source, the charge control circuitry configured to independently control each of the first and second input circuitry such that the at least one battery can be charged using the at least one solar panel and the external power source simultaneously, the charge control circuitry prioritizing charging the at least one battery from the at least one solar panel over the at least one battery, the one or more predetermined characteristics of the at least one solar panel comprising a known current-voltage curve, a known maximum power point, or a combination thereof.
