Ruark BackPack 3 Battery for MR1 and R1

The BackPack 3 status display and improved power management ensure the R1 Mk4 BlueTooth radio and MR1 Bluetooth Speakers work even better and longer than the last generation BackPack 2.

BackPack 3 attaches seamlessly to R1 or MR1 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 power-free listening, depending on volume.
