My concern about the Galaxy tab is regarding the cable used to charge the tablet. There is a PDMI – USB cable which plugs into a wall plug. If it is PDMI – USB, is it possible to connect it to any compatible USB charger? I am aware that it cannot charge from a PC, so I am referring specifically about wall chargers. Is it Possible to connect PDMI USB to any compatible USB charger? I would really appreciate your useful opinion regarding this. Please advice. Thanks.
