Can I use commercially available USB Type-C compatible AC adapters and mobile batteries instead of the supplied AC adapter?

It may be possible, but proper operation of the unit isn't guaranteed.

Use a USB PD 45W or higher, equivalent to the supplied AC adapter.

Refer to the [Specifications] in the Instruction Manual and Precautions for Use for supported specifications.

Especially when using a USB PD of less than 45 W, it may not be possible to power the unit from a commercially available USB PD product.

Commercially available USB PD products may not be able to supply power to the unit due to compatibility issues.
