For those who poo poo Rover's advice.
If you use certain types of accessory plug in any cigar lighter socket, you may find that the metal side pieces will become stuck in the cut aways that hold the cigar lighter in place. This can result in you not being able to pull the plug out & the excessive force required to pull the plug out & result in the side pieces being bent & possibly sort circuiting the socket.
At best blowing the fuse, at worst burning out wiring.
That's why, if you look at an 'auxiliary socket', it has smooth sides, but will not operate a cigar lighter.
Of course, you will find some plugs that are perfectly suitable for use in these Rover cigar lighter sockets, but some will not be. Rover are just covering themselves for the ones that are unsuitable.
Hope this clears this one up.
