The red Water Bottle Speaker from re-fuel combines a portable speaker and water bottle into one handy device. This 2-in-1 bottle speaker utilizes Bluetooth technology to stream music from compatible devices, such as smartphones and tablets. It also supports microSD cards, so you can load your favorite tracks directly onto the device. As a water bottle, it can hold up to 12oz of water—enough to keep you hydrated during a workout, bike ride, or spending time at the beach. The Water Bottle Speaker is made of non-toxic material, so drinking is perfectly safe, and its IPX4 waterproof rating means you won’t have to worry about water damaging the speaker. The built-in rechargeable battery lasts up to 4 hours on a full charge.
