The Green Lion Denali 30 Portable Speaker in black delivers strong audio performance through its compact design, which enables easy movement between locations. The speaker produces full sound through its 30W power output, which combines with its 3600mAh battery to provide four hours of continuous audio playback after one charging session. The system uses Bluetooth V5.3 technology to maintain stable connections through a transmission distance of 10m, which makes it suitable for outdoor events, travel, and home audio use. The device maintains its functionality in wet environments because of its IPX7 waterproof rating, and users can recharge it easily through its USB-C charging port, which enables fast charging from 1.5 to 2 hours. Users can answer phone calls through the speaker's hands-free calling feature, which also supports device connections through AUX and USB ports. Users can enjoy customizable visual effects through RGB lights, while the carry handle provides a simple way to transport the speaker to different locations. The TWS mode lets users connect two speakers to create a sound system with more audio dimensions.
