Abstract: A portable power supply including a housing, at least one battery cell, a charger, and an attachment. The housing defines a cavity. The housing includes an upper portion, a lower portion, a plurality of air inlets defined in the lower portion, and a plurality of air outlets defined in the upper portion. The plurality of air inlets is in fluid communication with the cavity. The plurality of air outlets is in fluid communication with the cavity. The at least one battery cell is disposed in the cavity. The charger is electrically coupled with the battery cell. The attachment is coupled to the upper portion. The attachment is configured to at least partially cover each of the air outlets such that airflow exiting the air outlets travels a circuitous path.

Abstract: An electrical device capable of emitting or absorbs energy relative a surrounding environment. The electrical device includes a housing, an interior volume defined in the housing, an energy sensor at least partially exposed to the surrounding environment, a first material having a first absorptivity, and a second material having a second absorptivity lower than the first absorptivity. The first material is nearer to the surrounding environment than the second material is at an energy sensor reading below a threshold energy range, and the first material is farther from the surrounding environment than the second material is at an energy sensor reading above the threshold energy range.
