Built for outdoor sound that stays full at higher volume
The ZEALOT S87 is aimed at one clear problem: most portable speakers lose body and bass once you move them outside. This model uses an 80W output claim and a 3.1-channel layout to keep music sounding fuller in open spaces, where small speakers usually thin out.
Zealot has built a recognizable reputation in the AliExpress Bluetooth Speakers niche by focusing on practical audio gear rather than flashy extras. Users often choose the brand for its weighty tuning, sturdy build, and feature sets that make sense for travel, patio use, and casual home listening, which is exactly where this model fits next.
What the 16,000mAh battery changes in real use
A 16,000mAh battery is the kind of capacity that shifts this from a desk speaker to a weekend companion. It is designed to handle long listening sessions, so you are less likely to keep it tethered to USB power during a barbecue, workshop day, or a full evening indoors.
The battery also makes the S87 more flexible than many mains-focused speakers in this class, especially if you want sound in a garage, on a terrace, or near a campsite table. The trade-off is that bigger batteries usually mean a heavier cabinet, so this is better described as portable than pocketable, which matters before you move on.
Bass that users notice first, not last
Real customer feedback points to bass as the main strength, and that aligns with what this speaker is trying to do. The cabinet is tuned for a more physical low end, the kind that gives drums a thump and makes bass lines easier to feel without pushing the volume into harsh territory.
For outdoor listening, that matters more than ultra-bright treble, because open air tends to swallow low frequencies quickly. If you usually listen to dance, hip-hop, or action-heavy movie audio, the S87 should feel more satisfying than a compact travel speaker, and that leads into how it connects.
Bluetooth, AUX, and dual pairing for fewer interruptions
The S87 supports Bluetooth and AUX, so it can work with phones, tablets, laptops, and older audio sources without much fuss. Dual pairing is useful when two devices need quick access, such as one phone for music and another for calls or playlists, which reduces the stop-start feeling common with single-device speakers.
Support for an app also suggests some level of control beyond the cabinet buttons, though the exact feature depth is not specified. For users who switch between indoor background audio and louder outdoor sessions, that kind of connectivity makes the speaker feel more adaptable than a basic Bluetooth box, so the build matters next.
Water resistance and the plastic cabinet: practical, not precious
The waterproof rating is a strong point for a speaker meant for patios, poolside use, or unpredictable weather. The plastic cabinet keeps the design lighter than metal alternatives and helps the speaker survive the bumps and scuffs that come with moving it from room to room.
That said, waterproof does not mean carefree, and the lack of a detailed protection class leaves some room for caution around heavy rain or full submersion. According to customers, the packaging and included strap, charging cable, and AUX cable were appreciated, which suggests Zealot is thinking about the use case as a whole rather than the speaker alone.
Who should consider the S87 instead of a smaller speaker?
This model makes the most sense if you want a louder, bass-forward speaker for home gatherings, outdoor listening, or casual entertainment where size is less important than presence. If your priority is crisp vocals at low volume on a nightstand, a smaller Zealot unit may be easier to live with, but it will not deliver the same room-filling weight.
The S87 is also a sensible pick for users who like a single speaker that can cover several roles without constant charging or complicated setup. That balance between output, battery life, and connectivity is what gives it its appeal, and the final question is whether that balance is reflected in the details below.
