Audiovox PVD80

Question

I bought this portable dvd player in the USA and want to use it in the UK. How do I plug it in? It says 9V-12V on the back and I was told if I try to plug it in and charge it up it would blow up! I see I need some kind of transformer for the power but don't know what. Can you help?
Thanks
