...Divx Player? I have 2 portable dvd players that we take on long journeys to keep our 2 children occupied (very different ages so need 2 as they want to watch very different films.) Currently the battery only lasts about 2 hours so I really want to buy in-car chargers for them---or even spare batteries that I could charge up if anyone knows where I could buy them instead! Does anyone make a 'universal' charger that would work for any portable dvd players? I'd be grateful to anyone with any suggestions please!
