As I understand it from the tag that was in my bag when new, the max temp is the same on l-m-h. It just takes longer to get to max. I don't know how much longer. It would seem better have a true l-m-h.I plug mine in on low overnight, if not 1-2 hours on high in the morning. If driving 30 minutes or more, plug in 12v in vehicle.
