Looking for a 12volt car charger for my Laptop. Yes there are loads of the damn things on eBay all around a fiver or tenner.....but none will fit my laptop which is a Dell Latitude E5500.The plug is unusually large with an o/d of 7.4mm. Maplins stock a 'universal' kit with the correct plug in but I nearly had a heart failure at the price......£40!! 150W Laptop Car Adaptor > Maplin Tried 'googling' with very little luck. Anyone any other ideas or know where i might get one at a more sensible price?
