Yes, you are correct, the specs are "Input: 12-18V DC, Output: DC 2.1A + 1A (Total 3.1A Output)" I did not mean to imply that it was two 3A outlets. What this means is that you do not want to plug in two high drain devices on one of these, for example two iPads, as they will charge slowly. However I have been fine plugging in an iPad and an iPhone into one of these.
There are other adapters out there with higher amps, but I have not tried them.
