Why does my tablet take 20 hours to charge up
Many tablets come with their own specific chargers and they have various voltage and amperage capabilities so that the tablet can charge at the set rate of that unit. Many people loose their charger and try charging their tablets using a charger with the same type of cable since many android tablets have the same type of connector for their charger as their android phones. But do not be fooled using the correct charger specifically the one that came with the tablet is best for rapid charging of the tablet. Also using an over powered charger for lower powered systems can also change the life of the equipment specifically the battery life span. So are you using the specific charger or charging cable for your unit?
