I'm looking for a wireless speaker without power cable and with integrated battery, mainly for outdoor usage.
In the past (August 2014) I have asked this question through Sonos technical support and they answered that Sonos planned to release a portable model with battery, expected launch in 2016.
However, I still can't seem to find such a model in the available products.
Anyone who has more information on this topic?
Otherwise, I am obliged to purchase a product from competitors, who do have this in their product range.
E.g. Bose SoundLink Revolve - https://www.bose.com/en_us/products/speakers/wireless_speakers/soundlink_revolve.html
