This is a nifty combo: a bluetooth speaker that can also double as a 2200mhAh power bank to charge your USB-enabled devices.

The good people at Braven built this bluetooth speaker specifically with the outdoors in mind. The speaker's housing is made with a crush-resistant frame and is IPX7 certified waterproof.

On top of all these great features, the speaker doubles as a smartphone (or any USB device) charger, and provides up to 12 hours of usage between charges.
