Why are EMP generators so expensive?

...why does a 13 year old need an EMP anyways lol

He wants to be a giant starfish. If he goes through with it, he will be expelled and he will have to pay for any damages that are caused.

one reason is that they're spreading their entire electric power into a massive field
reason two is that they usually end up being more destructive than intended

Anything big enough to do this is going to be way to big to bring with you
EX: A suitcase size model with an effective range of one whole meter

What would be even better is to get something that forgets with cell and wifi signals.

and then emergency services can't get reception
