I'm not sure but the battery may be changeable too. I know they are on the Samsung phones and a couple extra batteries and a direct battery charger means you never have to tether the device to a charger. The coolest thing I've found on this tablet so far is it has an IR remote controller and with the Peel app you can control most any TV/Satellite/Cable combo... even systems in bars that show shit you don't want to watch!
