The phones ( or any other device) will only draw the current they need to charge, Connecting a phone to a 2.1 amp capacity connection will not hurt it. Think of this as a 3 inch hose with a small spray nozzle on the end. No the flow is controlled entirely by the spray nozzle.

Is there any danger to phones from a 2.1 amp slot? If so...I'd be sure to include both types of jacks OR put a big idiot sticker there!
Anyway... other than that ...good idea. Right now in my G'Town all I have is a single dashboard cigarette plug. I'm splitting that into 2 ...then plugging in the GPS to one side and plugging in a small inverter with both AC & USB plugs since there are none of those up front. Probably would blow a fuse if I ever tried to use it all.
Providing an alternate way to charge stuff is a good move...no matter what class!
