What is the Iron Man Reactor for?

Didn't the landlord ever consider Iron Man armor because the small reactor was no longer needed because of the technical upgrade? I just watched the third part of the 3D version today! The last shot was given to the child, and all the equipment in the child's house was Tony's! Maybe it will come out again one day! Finally, he also said that what can be plundered and changed is the house, but what can't be changed is that he is the Iron Man, and a steel suit has not been destroyed-Colonel Rhodes's steel patriot!
