Thanks to the built-in battery, you can bring these party speakers anywhere. You don't have to connect the speakers to the socket, so you can place them wherever you want. If the speaker is water-resistant, you can also place it outdoors. This allows you to enjoy your music in the park or at the beach. The battery life differs per speaker, but you'll find speakers with a battery life from 3 to 25 hours here. The larger speakers have a handle, wheels, or both, so you can easily take them with you to your party location.
