Power connectors that are easy to connect, have a low profile, and can convey one or more data signals. One example can provide a power connector that is easy to connect by providing an axisymmetric connector receptacle and connector insert. Magnets can be used to help guide a connection between a connector insert and a connector receptacle. Canted springs can be used to provide a tactile response to the insertion of the connector insert into the connector receptacle and to help to secure the connector insert in place when mated with the connector insert. Keying or self-aligning features can be included on either or both the connector insert and the connector receptacle to help guide mating.
