Hmm... the
Charging page is a main item in the "hamburger" menu. It provides an overview and a link explaining all the charging options, including Supercharging, with large bold red "
Learn More" buttons that take you to the detail pages. Not exactly "hidden". Including the FAQ in the "Support" section (also a main menu option), is pretty standard.
I'm not sure on the "hard to understand" part. The Supercharging page actually includes an animated graphic depicting charge time. It's literally presented as "Here, let us draw you a picture".
So I can appreciate the sentiment of "
Maybe include a more prominent link on the main page, or include a link within the product data pages", but I think your claims of hidden hard to understand info is a bit over the top.
