Well I'm not here for a "Buy American" campaign. I'm building simple, indulgent gadgets, that don't require a failure probability analysis. This isn't product design, sir. It's just a hobby and learning platform, that will most likely never see a professional application. So I'll buy that "cheap Chinese crap", as often as I can, and lose little, in the process. And as long as we're all being consistent, consistently wrong will still be more understandable to the majority.
If the term "backfeeding" doesn't make sense to you, after both an explanation and a picture, then maybe you're not the right person to answer the question. I'm not able to be technically semantic about it, so you'll forgive me for using what I know. You haven't really offered me a better term, so...
