#57 Zealot S86: $98.99 Zealot eBay
Pros: Two 79mm drivers fed by a claimed 60W amplifier give the S86 genuine dual-driver hardware for its size, and Zealot publishes a 20Hz - 20kHz response plus under 1% distortion. The 8000mAh battery (two 21700 cells) should cover long outdoor sessions, while IPX6, a moulded carry handle and a supplied adjustable shoulder strap suit camping, cycling and beach use. Bluetooth 5.4, TWS pairing, Type-C charging, TF/USB/AUX playback, multi-scenario EQ presets and RGB lighting round out the boombox feature set. No independent lab has measured output, distortion or bass extension, so real-world performance is unverified. Techder Audios calls it one of the better Zealot models and good value at its price.
Cons: Zealot publishes only a headline 60W figure, with no RMS-versus-peak clarification, sensitivity or maximum SPL, so real loudness is unknown. The 8000mAh pack is modest for a 60W boombox, no playtime or charge-time figure is published, and runtime will fall sharply with EQ, RGB lighting and high volume. No companion app or Bluetooth codec support is published, there is no power-bank output, and no warranty term is given. At 2.38 kg it is not a pocket speaker, and no independent measurements exist to confirm the claimed 20Hz bass extension. Techder Audios reports sizzling distortion at high volume with heavy bass boost and places it below the Xiaomi Sound Party and JBL Xtreme 5 on sound quality.
How it compares: Just above it: Zealot S167 - $81 more. Just below it: Harman Kardon Onyx Studio 4 - $1 more.
