Along with or Instead of the current charging base option that is all one connected piece. The Sonos Move should have an extra option for purchase that receives power via USB type C and an accompanying 45 watt USB-C PD charging block 

also preferably detachable form the cord). Type C to Type C cord preferably for future proofing.

This would help stream line the product as it can be charged via the USB type C when being transported or use on the go. 

This was almost a deal breaker for me when trying to decide between the Sonos Move and the Bose Portable Home Speaker. As the Bose PHS has a type C charging base and can easily be charged with an ordinary android or apple type c charger
