BackPack 2 Battery for MR1 and R1
The optional Ruark Audio BackPack II battery allows you to enjoy the MR1 or R1 products without a power cord. Placing batteries inside MR1/R1 would steal valuable speaker capacity, but BackPack II allows MR1/R1 to retain its rich mains powered performance with the benefit of complete portability.
A total evolution of the original, BackPack II attaches seamlessly to MR1/R1 and once fitted can be left permanently in place as it charges automatically whenever mains power is re-applied. A full charge will provide up to twelve hours of mains free listening depending on volume.
