Yes. If you use a USB AC adaptor or an Apple USB-C Digital AV Multiport adapter / Lightning to USB 3 Camera adapter (both commercially available), you can livestream while supplying power to your device that features a USB Type-C® port or Lightning connector.
For details, please refer to "Using devices with a USB Type-C® port" or "Using an iPhone/iPad equipped with a Lightning connector" in the GO:PODCAST Owner's Manual.
NOTE:
- When using an iPhone or iPad equipped with a Lightning connector for recording or streaming, it is especially recommended to charge it.
- In some cases, even when the smartphone is charging, the remaining battery power may not increase and could even decrease, depending on the type of USB AC adapter you use and the status of the GO:PODCAST app.
