We perform the thermodynamic and shadow radius analysis of an electrically charged black hole (EC) with electric charge q and coupling constant μ obtained from the Einstein-Euler-Heisenberg nonlinear electodynamics. For μ=0.03, we have four solution branches of the horizon including low, hot, negative, and cold ones, while for μ=0.3,3 there exist single branches without limitation on q. The shadow radius for the low branch is the nearly same as that for the Reissner-Norström black hole for q<1 case, while one finds the q>1 negative branch which is constrained by the EHT observation.
