That said, the most important aspect was the cord. The bum cord from Amazon caused it to discharge while plugged in. So, it's nice knowing I can get a spare.
Beware certain third-party sellers on amazon; he was bribing customers for good reviews with free "something or other." Terrible; I reported him.
Get a terrific cord! Seriously.

It's more importantly the 'gauge' of the wire IN the cord- the heavier the cord, the more current it can feed the phone. The cable I'm using at the moment is "18AWG", nice and heavy duty, and can feed the full amp from the stock samsung charger, and nearly 1.5A from the charger I normally use. The stock cord that came with it, barely pushes the full amp from the stock charger, and most of the other 'charging cables' I've gotten over the years handle about 1/2-3/4 that at most. The thinner and flimsier it is, the less it can handle as a general rule, though I've found some 'heavy duty' ones that are just thin ones with extra thick insulation, so you can't always judge on that alone :/
I've charged my Note 2 on a 5.0v 5A DC power supply, just fine, it seems to be able to draw about 2.1A max, though I haven't done any real testing about it. If it's on a cable that allows less than about 700ma, though, it WILL discharge on the charger, especially if the screen's on or it's doing something like playing music, etc. 850ma seems to be the break-even point for me, at least with the screen on.
I know I can hook it to a 5A charger without a problem, or a 20A one even, and it'll just draw what current it needs- voltage on the other hand, I know better, and I've seen more than one device fried by the wrong voltage- which is why I asked what i did about the Note 4's charger. I don't expect to see the same behaviour on the Note 2, but if it's ABLE to handle a 9v charging line, it'd definately affect it's charging speed for the better, too
... Ii'm just not willing to risk trying without asking around first!
