I have had some degree of success with one purchased from Asda, the brand I don't recall, but it's defining feature is the 'lighting' end of the charger is cranked at 90 degrees, I suspect this makes the bit that most yank the thing out by more robust .....
Mine gets used multiple times daily in my van for work, and still going strong. I'll see if I can find a link in a bit for you.
 turns out they are quite common
(must get out more).
