The odd thing is that the cable going to the laptop is probably too thin/not stress-relived enough (I've "only" had one fail but it seems a marginal design). However, at the same time, the alternate plug with the extension length of cord attached practically looks and weighs like something I'd attach to a mainframe. I don't travel with it for that reason. It's always seemed to me as if the two different components were designed by engineers who didn't even talk to each other--and it's been that way for years.

There may be a UL thing going on at the 120/240V side of the charger but it still seems ridiculously overengineered.
