Charging your phone by digital television

These days when most of us own phones which can be charged by USB. On this trip I decided not to carry my laptop because of ubiquitous cyber cafe here. My iPod lost all the charge after continuous use today. I read books on this device, update my blog and is becoming my primary device to access internet and learning new things. It's the convenience of carrying something so handy that makes your net book now seem like a mammoth. So when I came here with some trepidation I decided to charge my iPod using the television at my hotel. The thing which gave me confidence was the USB standard itself. Hopefully you too may find this useful next time when you are traveling.
