Mac Power Monitor
Mac Power Monitor
is a graphical, easy-to-use interface for the energy and
power measuring features of macOS. A large number of
statistical evaluations can be retrieved, such as a power
overview, process statistics, data transfer bandwidths of
hardware components, interrupt sources, interrupt
distribution, processor core data, and much more. The data
can either be recorded live at a rate of 1 measurement per
second, or as a one-shot operation with any adjustable
duration of 1 millisecond or higher.

The software is distributed electronically. You can download the product and test it before you decide to purchase a license for unrestricted usage.
