I got a Sonos Arc from USA. I know the device itself switches to 220V (range 110-240V) but the power cable is rated 125V. Can I use the same power cable in India (220V) or should I get a new power cable from India
Just plug it in to the mains socket, using an adapter if needed to make the physical connections. It will work as long as it is not under the shadow of all the chaos going on within the world of Sonos software. Assuming here that the power cable is one supplied by Sonos, in the original unopened packaging.
