1. Depends on the recording. It can take up to an hour if the recording is not automatically prepared to be transferred.
2. We do not support it, but in your case it may work. Your device would connect to the HGo's network, so it will depend on your device.
3. It does run off battery but can be plugged into a wall outlet if you have the proper connections. It charges with Micro USB
