Hey hey hey - nothing wrong with ciggy lighter expanders .... in a landrover! My mate has loads as he flys commercial hot air balloons and needs to charge loads of stuff all the time like GPS, multiple radios, laptops, cameras etc.
Small world isn't it? I had a flight with him if he's the chap who does flights out of Pheonix Green and other places in the region. I bumped into him at the bakers in Hartley Wintney a couple of weeks back.
