Can I use the iPhone or iPad USB AC adaptor to charge the HT-AX7 speaker?
If you use an AC adaptor other than the one supplied with the HT-AX7, it must be a 15 W (or higher) USB PD compatible AC adaptor and use a USB Type-C cable (compliant with the USB standard) that supports USB Power Delivery (USB PD).
Note: If you are not sure if the AC adaptor or USB Type-C cable supports USB PD, consult the adaptor or cable manufacturer.
