I agree to what @dieterdreist has already written. A minor item like a waste_basket or a bench inside a public transport shelter may be tagged as properties of the latter but in general separate physical objects should be mapped as separate data objects.
Those locker boxes are well worth to be separately tagged so I would not support the 1. Case.
In view of the 2. Case: Considering that these lockers are neither real luggage lockers nor simple charging stations I would vote for a new tag, something like
amenity=charging_locker
completed by additional tags like capacity, fee, socket_type and the like.
Charging_locker is precise enough to describe the purpose of these kind of object and generic enough to include charging of other devices than just bike batteries.
