Wow you are really dead set on that. Does Leon have any background in working with hardware in any case?

Not to mention we're in a town with a gym, I'm pretty sure there are a few handymen around, it's not a small village.

And again.

The gym would have one too. Pretty sure there are repairmen for these machines in pretty much every larger town like this one.

EDIT: Oh nevermind I see it in his backstory now. Still though, I'm pretty sure the various authorities would spot him carrying a large machine that looks suspiciously like the Pokemon Center equipment. You might get a little visit shortly.
