When selecting a USB cigarette lighter charger do I select by the total output in amps?
For example:
If I got a 4 port charger rated at 2.1 amps. Does that mean that the total output is 2.1 amps for the charger?
Or do the 4 ports divide the 2.1 amps into .525 amps for each port? (I'm thinking this way but want to be sure)
I've been looking on Amazon US for a good dual port cigarette lighter charger but get a little confused at the array of different output ratings stated in the search. Most results are returned by device types like cell phones, tablets and such.
EDIT: I finally got it! The amps divide by the number of ports.
How about this one:
