The answer is yes you can buy a 230v to 12v transformer to run it but this will mean you need electric hook up and will need to possibly separate other 12v circuits to stop it overloading the transformer .Why not buy a new leisure battery and assuming you have a charging system built in to your camper van it will then work correctly and let you use sites without electric as well as those with electric.Cheap battery £40-£90 depending on Ah
