A wireless charging system, based on any suitable wireless charging technology(ies), allows easy access/discovery, registration, authorization, monitoring, and/or compensation for charging services. The technology uses donor mobile radio nodes (12) that register as potential charging stations for requesting radio nodes (14). The donor and requesting nodes negotiate the charging event, and in a preferred example embodiment, payment by the requester for the charging service to donor is arranged. ## Claims ### Claim at position 1 1-35.
