I have 2 of the duxtop’s linked in the article as my only range. Before going to this setup I tested them against my gas range and they were 2 to 3 minutes faster at boiling water. The issue with the portable ones is the quality differential. You’ve got extremely cheap ones that are more plate warmers than cooking appliances and you e got the control freak that is a piece of future tech. But if you get ones that a caterer would use they tend to do the job.
