ZEALOT S51 Pro 40W Outdoor Bluetooth Speaker — IPX6 Waterproof, Dual Pairing, 5200mAh

Robust sound in a portable package: The ZEALOT S51 Pro delivers a rated 40W output from two 57mm drivers, producing clear highs, balanced mids and strong bass. Its measured frequency response is 100Hz-20KHz (with some sources listing 20Hz-20KHz), ensuring dynamic playback for music and movies. Waterproof and outdoor-ready: Built to an IPX6 waterproof standard, the speaker resists powerful water jets from any direction, making it suitable for use at the beach, poolside, or in wet weather. Flexible connectivity: Pair wirelessly using Bluetooth version 5.0 or 5.2 for stable transmission, or play files directly from a TF card or USB disk. An AUX input is also available for non-Bluetooth devices. Stereo expansion: Dual pairing lets you link two ZEALOT S51 Pro units to create a wider stereo soundstage—ideal for larger gatherings and outdoor parties. Portable design and battery: The compact housing measures about 86×88×200mm and weighs 703g, and some units include a lanyard for easy carrying. A built-in 5200mAh battery provides long-lasting playback on the go.
