Connecting your device to USB accessories
You can use a USB Type-C™ host adapter to connect your device to USB accessories such as USB mass storage devices, game controllers, USB keyboards, and USB mice. If the USB accessory has a USB Type-C connector, a USB Type-C host adapter is not necessary.
USB Type-C host adapters are sold separately. Sony does not guarantee that all USB accessories are supported by your device.
If your device is fully charged, it can be used for up to one hour without being connected to a power outlet.
