I have a 2015, but this may apply to all years. There are three 12-Volt power outlets in my CT: Front, Center Console and Cargo. The owner's manual provides a good description for the fuses for the front (Driver's Side #23) and for the cargo area (Passenger Side #16) receptacles, but not for the Center Console.
After about an hour on my knees with a flashlight, and some further research, I finally determined that the fuse for the Center Console power outlet is #12, on the passenger's side. In my manual, this circuit is marked as "SMART" and rated at 10 amps. (although there was a 15 amp fuse in place).
I replaced the blown fuse with a new 15 amp, low profile fuse and all is well.
With a little luck, this will save someone time and frustration down the road.
