Plus, if you’re outside all day, you don’t have to worry about a recharge: this small but mighty speaker features playback of up to 20 hours on a single charge (and if you run out of battery life away from a charger, we recommend boosting your play power with a solar charger). It can also handle water splashes by the pool, thanks to its IPX7 waterproof rating. Best of all, because it’s considered a rugged device, the 3.21-pound device is light enough to carry deep into the forest for off-the-grid camping experiences.
