I lost the charging cable that came with the device, and was wondering if I could use any USB charging cable to charge The Star Trek Bluetooth Communicator.

Yes. The Bluetooth Communicator comes with a Micro-USB charging cable, however, any good quality micro-USB cable can be used to power the charging stand which will then charge up the Communicator.

Yes, any usb with the right end can be plugged inti the cradle.
