#52 Zealot S39: $78.99 Zealot eBay
Pros: A triple-driver array rated 60W total (1 x 30W plus 2 x 15W) is unusually high claimed power for a portable this size, so it should play loudly enough for outdoor use. The 7200mAh battery is large for the class, and Bluetooth 5.0 plus AUX, USB flash-drive and TF-card playback cover wired and offline sources without a phone. At 375 x 150 x 154 mm and 2.34 kg gross it stays carryable. The claimed 80Hz bottom end suggests mid-bass punch rather than true sub-bass. YARNZO Tech’s full review and sound battle rate it competitive for its size and price.
Cons: No independent measurements or spinorama data exist, so real frequency response, distortion, directivity and bass extension are unknown. The published 80Hz low-frequency limit is high, and no IP rating, playtime hours, charging time, codecs, app or EQ are specified, leaving ruggedness and runtime unverified. Bluetooth 5.0 is now dated, and the 2.34 kg gross weight is heavy for genuinely portable use.
How it compares: Just above it: W-King D8 - $9 cheaper. Just below it: JBL Xtreme 2 - $121 more.
