If outdoor adventure is a part of your life, you need a portable Bluetooth speaker that can keep up. The rugged JBL Charge 3 isn't just weather-resistant — it's full-on waterproof. So sand, surf, or snow won't affect it — or its ability to crank out your tunes with rich, full sound. The speaker's built-in rechargeable battery can deliver up to 20 hours of continuous operation. And the Charge 3 can also keep your smartphone recharged so the music can keep playing.
