I've personally come across the vendors on the street peddling lightning &
microUSB-USB cables that when I tested on my kid's iphone & my galaxy
Note 2, does help to charge up the devices faster (even faster than original
cables).
Q1:
Question is, if I wanted to buy from online (Amazon, eBay), how can I
determine if they're really the fast charging ones?
Q2:
Any to recommend for galaxy note 2, iphone 6 & for fast charging of
power banks?
A lot of 3rd party lightning cables fails to charge (giving the message
"this accessory is not supported" on the iPhone) but I have 2 such
cables (which are not certified to be MFI) which still works till today

Why are the above advertised as "fast charging"? I personally came across non-original lightning cables
that connects to same power source that could the same iphone faster than original Apple lightning
cables but these are rare. The other non-original usually charges significantly slower
