The Hawking radiation temperature and evaporation speed of a black hole
(according to Hawking’s theory) is directly related to its current mass M
and initial mass M_0 *only*:

   T_H ≈ ℏ c³∕(8π G M k_B)

  t_ev ≈ 5120π G² M_0³/(ℏ c³)

A black hole is not an atomic bomb.

Pardon?

What about it?

This not even popular-scientific description of black holes is wrong.

Only a rotating black hole can lead to another universe (whatever that may
be), so that possibility is fully described by the black hole’s angular
momentum and electric charge.

What do you mean, what charge?

> Neutron stars have charge

No, they do not.  “A particle with zero electric charge” is what “neutron”
means.

A neutron star does not consist entirely of neutron gas: it has a thin
crystalline shell.  But it stands to reason that its total electric charge
is zero.

Black holes with non-zero electric charge are entirely possible.

No, electric charge is one of the conserved quantities.  It cannot be
created or destroyed, only transferred.

For example, when a neutron star is formed, the one-time positively charged
protons in the nucleus and the one-time negatively charged electrons in an
orbital around the nucleus combine each to form electrically neutral
neutrons (electron capture):

  p⁺ + e⁻ → n⁰ + ν_e
