HI,
using a Raspberry PI zero w and a SABREberry zero DAC.
connected to a JBL ontour XT speaker system.
Both! powered from a solar powerbank.

to connect USB power to the JBL, you have to open the battery compartment and connect it there.
(the outside connector is only for 12V)
average power consumption of complete system is 2-3 watt.
hm, maybe the volumio device will fit in the battery compartment when saw a little bit…
