A small, dependency-free Ruby toolkit for reasoning about USB-C Power Delivery (USB-PD). Model chargers and devices by their fixed PDOs, negotiate the optimal voltage/current contract, rank chargers for a given device, and check whether a device will reach full rated power — useful for e-commerce spec tooling, IoT fleets, and electronics catalogs.
