Your BOOMCUPZ Vibez Wireless Speaker Cup provides a clear signal when it's time to recharge. You'll hear a "low battery, please charge" sound when the battery level drops below 3.3V, signaling it needs power. To recharge, use the included USB cable. Connect it to a computer's USB port or a suitable power adapter. For a complete charge, allow at least 1.5 hours. Ensure your power adapter has an output voltage between 3.2V and 4.2V. For the best experience, fully charge your BOOMCUPZ speaker cup before its first use.
