Good day Im looking for a Downloadable User Manual for Sansui ETab 902VP (Build No. Sansui ETab 20130918). Type of charger (volt/amps) required (jpg) to successfully charge Tab; one provided by supplier does not sport the Sansui brand name and appear to overheat easily. Packaging does not specify amount of hours device must be charged before use. Could you assist , advise? Best Regards L Brock
