Turn up the adventure. The VolkanoX Adder Series Bluetooth Speaker is a serious portable powerhouse — 40W RMS / 58W peak, IPX5 water resistance, a built-in powerbank, and LED light effects, all in one rugged package built for the outdoors.

Two 3.5" drivers push out massive, room-filling sound with a sensitivity of 86 dB and a frequency range of 80 Hz – 12 kHz. Want even bigger sound? Pair two Adder Series speakers together for True Stereo Sound that fills any space. The 4 400 mAh battery keeps the music going for up to 7 hours, and the 5V/1A powerbank output means you can charge your phone directly from the speaker when you need it most.

Connectivity is fully covered: Bluetooth 5.0 with a 10m range, Aux input, SD card slot (up to 32GB), and a built-in speakerphone for hands-free calls. The IPX5 water-resistant build handles splashes, spills, and outdoor conditions without missing a beat. And when the sun goes down, the LED light effects keep the vibe going.
