Cigarette lighter needs to stay always on

I tried to search this solution to my problem but didn't find similar question on this forum. So is there a way to have cigarette lighter always on?
Some MBs have option to change lighter behaviour by changing fuse locations so that lighters are always on, instead of turning off when ignition turns off. But R171 doesn't seem to have this option when looking fuse locations.

Follow exactly to update: ‘Usercp’ at the top of page, then ‘edit your details’ on the left side, ‘additional information’ near the bottom, edit your ‘location’ and ‘vehicle’. Info in your garage does not update your profile.

You can change the 12v positive feed to one from the end of the dash fuse box with an "add a fuse" easy enough, they're all 12v permanents there....
If I were to make that change what Amp rating would you suggest as that would seem to be a reasonable load? :O)
The original fuse for the lighter is 15A, so 10-15A should be fine..
Thanks for the info.
I tried to look "add-a-fuse" adapter, but can you please elaborate how it should be connected?
It's a piggy back device for getting another power feed from a fuse slot without loosing the original circuit

Very handy little bit of kit

You just pull a fuse from your fuse box and place it in the lower of the two slots on the piggyback fuse, you then put a fuse of the rating youdesir in the top slot and place the piggyback fuse in the original fuse slot on the car.
