Air-drag powered devices are provided for automatically maintaining a target inflation pressure or for equipping vehicle wheels with additional functionality. One illustrative device embodiment is an air compressor that attaches to the wheel of a vehicle to turn with the wheel as the vehicle moves. A drag member extends from the body of the air compressor to alternately present opposing surfaces to the air through which the vehicle passes. The air drag on the member thus creates an alternating drag force that powers the air compressor. Another illustrative device embodiment is an energy harvester that attaches to the wheel of a vehicle to turn with the wheel as the vehicle moves. A drag member attached to the base of the energy harvester presents alternating surfaces to the air through which the vehicle passes to derive a reciprocating motion suitable for generating electricity usable for powering wheel-mounted sensors or lights.
