    is there any danger if I plug my iPhone 7 or SE into a Samsung Fast Charging USB charger?

    The Samsung Fast Charger's output is listed as: 5V 2A or 9V 1.67A.

    Or how about just any Samsung regular phone charger that's rated at 5V 2A?

    Both Apple USB chargers that came with my iPhone 7 and SE are only rated at 5V 1A.

    it's actually the original fast charger that came with
    my Samsung Galaxy Note 7, which is why I'm kind
    of concerned. :) :(

    (don't worry, the Note 7 was already returned to Verizon,
    but they didn't want any of the accessories, so I kept
    using the charger for other phones)

    The phone "talks" to the charger to figure out the best rate between them. The issue you will have is that apple talks one language, and Samsung (android) talks a different one. Since the phone can't understand the Samsung charger, it will then default to the lowest USB standard 500ma (.5Amps). This is the same speed like plugging it into your windows pc, you will get fairly slow charging (but it will work).

    A better solution is to either get another apple charger, or buy a charger that can talk both languages. (Anker chargers with the IQ technology for example.)

    It won't fast charge. The battery and the circuitry connecting the battery need to be designed for it.

    Your more likely to damage the phone and battery.

    On any phone only use the chargers made for it unless you knows for certain they charger is industry standard. Apple's and Samsung's are not.

    Usually,it's best to use original. Wrong charger might not only destroy the phone,it can also cause a fire,which might cost your life,and the lives of everybody else sleeping in the building.
