Planck power

The Planck energy divided by the Planck time is the Planck power P_P, equal to about 3.62831 × 10⁵² W. This is an extremely large unit; even gamma-ray bursts, the most luminous phenomena known, have output on the order of 1 × 10⁴⁵ W, less than one ten-millionth of the Planck power.

In terms of the fundamental constants of physics, it is given by
