I'd go for opening the case and wiring it in every time.

Put it in a small, preferably metal, box from Maplins (or your local
electronic parts retailer) looks neat. Some of these have LEDs, letting
you mount it by gluing the LED into a hole in the box lid, or just hold
it down with a Pritt adhesive foam pad or two.

The 'cigar lighter' sockets are far too prone to act as a randomly
triggered USB-charger launcher, IME anyway. Strapping the charger into
the socket with insulation or duct tape just looks disgusting.
