The One SL doesn't have a battery. It's AC powered only.
Crikey I never knew that. Thanks so much - that makes life very simple.
Are you sure you own a One SL? Not a Roam or a Move - the only Sonos speakers that are battery powered?
Are you aware a non-Bluetooth Sonos speaker cannot be used in most hotel environments without a travel router?
Thanks for that. I just bought it in Australia and am taking it home to NZ soon - this the question about flights. Cheaper over here and you get the sales tax back at the border. Must admit I thought they were battery powered but doesn’t matter as I intend to use it indoors. Thanks for the assistance.
