Anything wrong with charging with a 2.1A charger?

[New Daddy]

I have a dual car charger that has a 1A outlet and a 2.1A outlet. I believe the 2.1A outlet is for iPads. Is charging my Droid 4 through the 2.1A outlet going to cause any damage to Droid 4? It looks like Droid 4 gets charged faster through the 2.1A outlet, but I wanted to make sure there is no downside to it.

I've been using a 2A charger in my truck for several months now (got my D4 the day it came out), and have not had any issues, other than charging fast
