I originally bought this to power a Squeezebox Touch and it has since been providing sterling service in my system for a succession of electronics, most recently the Allo Katana.
Comes with DC connection and a USB C adaptor. Condition is good - it's a black box with a blue light on it.
£125 + £9.75 P&P.
