This used unit is fully functional and ready to perform.

For performers and presenters searching for the best battery powered PA speaker for outdoor events, the Roadjack 10 stands out with its all-in-one design: built-in wheels and an extendable handle for easy transport, onboard 2-band EQ with echo, and a media player that supports Bluetooth, SD card, and USB playback with genre-specific EQ presets.
