I have a question about the home charger for the TT. I looked on TT's web site and it has a home charger that'll work for my device but it tells no specs. It's the universal usb home charger,my question is,what's the output. The reason I am asking before I buy it is because I have a blackberry I no longer use but the charger still works and it's output is 5Vdc at 0.7A. I don't want to destroy my device so I am asking before hand. Thanks for any help.
