It’s not the most powerful speaker out there, but if you need to use it for a quick presentation, it would be handy. You could also use it for music when you need something extra to listen to with a group of friends.
The device uses a tumbler design that’s supposed to be based on cutting edge technology that was created for the USA Navy. It comes only in the black with the metallic accents and includes a USB cable. That cable is the source of the speaker’s power.
