Do you remember the Honda Mobile Power Pack e: ? Sure, the name might be cumbersome, but at some point, we just have to accept that Honda likes sticking an "e:" at the end of all of its most recent things involving electricity.
If you've been around for a minute, it's kind of like how everyone had to make a big deal about moving from carburetion to fuel injection by sticking an "i.e." or an "i" at the end of a model name when the technology was not yet the norm. Then eventually, that got phased out and it just became the way things were.
