A:AnswerDon't know. Works well for Galaxy S9+ well enough that I have three of them for home and work/travel. All have worked well for past 1 1/2 years.
A:AnswerYes, it will connect to your faster charger & continue to fast charge your Note 5. Mine worked fine for about a month or so before the mini USB began to loosen its connection to the phone though & would make constant sounds of "charging" then "Not charging". It drove me crazy so I returned it.
