Embodiments of portable power supplies are disclosed herein. One disclosed embodiment, for example, comprises a circuit configured to input an electrical power signal, modify at least one electrical characteristic of the power signal, and to output a modified power signal (e.g., a DC-AC inverter). The circuit is enclosed by and secured within a housing that includes an anchoring region adapted to interface with a cup holder. In certain implementations, the housing is substantially cup shaped.
