We consider a particular Bardeen black hole in 2+1-dimensions. The black hole is sourced by a radial electric field in non-linear electrodynamics (NED). The solution is obtained anew by the alternative Hamiltonian formalism. For r→∞ it asymptotes to the charged BTZ black hole. It is shown that by inserting a charged, thin shell (or ring) the charge of the regular black hole can be screened from the external world.
