As long as the output of whatever you use is <5V dc and <2A, it will charge your T/T. I asked T/T to confirm the output of their own chargers and the figs here are from them.
If you buy a Sony mains charger for their MP3 Walkman range and have suitable USB to ? lead [whatever termination your device requires] you can use the Sony to charge a variety of devices because it has a standard USB socket, not a hard-wired lead.
The Sony outputs 5V dc at 500mA, so although it will take a bit longer to charge a T/T than a T/T charger, it will do so safely - and it will charge a Sony MP and any other gizmo that you offer up, if you have a suitable USB lead. In the case of a T/T, standard USB to mini USB leads are ten a penny. T/T supplied one in the box.
