A method for latching an electrical connector includes aligning a connector with an inlet. A first surface of the connector is within a first distance of a second surface of the inlet. A puller arm of the connector is extended into the inlet to a second distance from the second surface of the inlet. The puller arm includes a gripping element configured to apply a first compressive force against the inlet. The puller arm is retracted relative to the connector while applying the first compressive force against the inlet. The puller arm remains in the inlet at the second distance, thereby inserting a first electrode of the connector into the inlet to connect the first electrode with a second electrode of the inlet. The first electrode transfers power to the second electrode from a high-power supply.
