Recently, I was rewatching spiderman: homecoming and i got to the portion where Peter was trapped in the Damage Control vault. There, him and Karen have a monologue together, getting to know each other. But this caused a question to form in my mind, how is Karen being powered? There can't be an arc reactor in it correct? Is it battery powered? Does the homecoming or far from home suit need to be recharged? If the power source is indeed limited, what would happen when it runs out? Would peter be unable to switch between different webbings or would be even able to use it at all?
