A:AnswerIt only includes the USB A to C cable and a QC2.0 charger. It is unclear if that cable is an actual USB 3.1 certified cable. I have not confirmed that yet with actual use. I point this out because lots of what you see on Amazon are actually USB 2.0 (referring to ones with USB C connector) cables and lots of people are angry about that. The charger is QC2.0, which is the fast charge capable charger. It can do this will the included USB cable or be used with a fast charge capable wireless charger. Keep in mind that not all wireless chargers are fast wireless chargers. The fast ones require the QC2.0 feature, which actually outputs 9V from the charger, instead of 5V. Your older high-amp charger may not be able to do this. So, when you shop for your stand get the fast charge type and keep in mind that you will need a QC2.0 capable charger plug to go with it.
A:AnswerThe charging cable, obviously, is different. The Note 7 uses USB C, while the Note 3 uses USB B Micro (or that other USB B Micro that is SS rated and looks weird). So, the cable for sure is different. The charging brick will work for either phone. In fact, anything with 5V/2A or better with a USB A connector on it will work just fine. I have used my Note 3 power brick (which I believe is 5V/2.1A) to charge my Note 7 and compared the charging times to the Note 7's charging brick (which is has the QC 2.0). The charging times are not really that much faster with the QC 2.0 if your phone has 30% or more battery when you start charging. Maybe an extra 5% of charge per 30 minutes. If your phone is about dead, however, that's where QC 2.0 will be the runaway faster charging technology.
A:AnswerLol, I really dont get what you mean. It is a Samsung Note 7, which is Samsung primary flagship phone. It is typically the most full-featured phone they make in any given calendar year.
A:AnswerI believe that $50 difference was a MIR type deal, where it could take 12 weeks to get the credit to your service bill. I opted to skip all that and bought outright primarily because they also force you into a more expensive plan with the subsidized deal price. So, be weary of the "deal" with the 24 month commit.
