RuarkAudio BackPack3 Battery Pack

BackPack 3 transforms the R1 Deluxe Tabletop Radio, MR1 Bluetooth Speaker System and R1S Smart Radio into completely portable products.
It frees these miniature marvels from the mains power socket and into the bathroom or onto the decking and the great outdoors. Placing batteries inside takes valuable speaker capacity which can result in unrefined sound, but BackPack 3 allows R1, MR1 and R1S to retain their rich mains powered performance, but with complete portability.

The BackPack 3 rechargable Li-Ion battery pack attaches seamlessly to R1, MR1 and R1S speakers 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.
