Is it possible to get higher than a 2A charger for the D-class?

Is it possible to get higher than a 2A charger for the D-class?
I would like to do a road trip with a recharge at lunch time.
I think a 2A charger would take too long.
Are there any higher A charger options?
Thanks.

I found these at Amazon not sure about the voltage, but is 4A enough?
