Not even close. My (excessive) estimate in another thread is 1e33 J, which would have a Schwarzschild radius of about 16 picometers, and something (I don’t really understand it) happens if a black hole is charged which makes the event horizon radius smaller than the Schwarzschild radius.
Now I’m wondering what would happen if you tried to create a black hole purely from the energy density of an electric field. Do you asymptotically approach an extremal charged black hole? Or do you make a super-extremal black hole? I’ve heard conflicting claims about if super-extremal is even possible.
