For the cigarette lighter, you are looking for a 15A fuse. The fusebox will be on the right side footwell/kickpanel. Open the plastic cover and you should see 2 rows of fuses. The fuse holder/remover should be on the left row. That 15A fuse directly below it is what you need to check.The cover should be labelled "CIGAR LIGHTER"

For the other power outlets, you need to check 2 fuses.
1. The same fuse discussed above
2. A 20A fuse
This one is located in the engine bay, by the battery. I believe it's the one closest to your positive terminal. Open the cover and you'll see 2 20A fuses. It's the rear-most one.
