1. A method comprising:
connecting a plurality of electrical contacts to a housing, where the plurality of electrical contacts comprises at least one power contact and at least one interruption detector contact, where the at least one power contact is movably connected to the housing;
connecting a first plurality of magnets to the housing, where the first plurality of magnets comprises a first magnet having magnetic poles orientated differently relative to magnetic poles of a second magnet of the first plurality of magnets, and where the first plurality of magnets is configured to allow the housing to be connected to a charger port with the first plurality of magnets and a second plurality of magnets on the charger port providing a magnetic holding force with each other and providing alignment of the housing with the charger port to magnetically hold the housing at the charger port at a predetermined position,
where the at least one power contact is configured to disconnect from at least one power electrical contact of the charger port, when the housing is being disconnected from the charger port, only after the interruption detector contact disconnects from an electrical contact of the charger port.
