The Solar Sound Outdoor Bluetooth Speaker has a portable design, making it the perfect companion for any outdoor event. When the speaker isn't being used outdoors, it becomes a great desktop speaker. Its 5-watt output fills any space with quality sound, while its IPX6 waterproof rating protects it in wet or rainy conditions. The speaker has a built-in solar panel. The solar panel will recharge the speaker in less than 8 hours. In addition to the solar panel, the speaker can be charged using the provided Type C charging cable. The attached silicone loop makes it a great option for on-the-go transportation. It offers up to 6 hours of playback at maximum volume when fully charged and charges from 0% to 100% in less than 1 hour!
