Aspects of the invention are directed to a cart that includes a structural element, a compressor assembly, and a pressure regulator. The structural element may be a tubular frame member, a handle, or a deck. The structural element defines an internal storage volume within it. The compressor assembly is able to deliver compressed air to the internal storage volume. The pressure regulator assembly is able to deliver compressed air from the internal storage volume at a regulated pressure. Advantageously, embodiments in accordance with aspects of the invention provide cart designs that are capable of both transporting heavy loads and serving as sources of compressed air. A user utilizing one of these carts therefore does not need to bother with transporting a separate air compressor to a worksite. Instead, air compressor functionality is conveniently built into the cart and the user's workload is thereby reduced.
