Short answer: the Zealot S39. It ranks #59 of 103 large speakers by sound quality, rated 3.4/5, at $78.99; the Zealot PT01 ranks #73, rated 3.1/5, and costs $79.99, which makes this an easy call rather than a real tradeoff.
What the Zealot S39 does well: 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 tradeoff: No independent measurements or spinorama data exist, so real frequency response, distortion, directivity and bass extension are unknown.
The Zealot PT01 is the lighter option. A compact 14.3 x 12.2 x 14.5 cm, 3.2 lbs (1.47 kg) cube with a moulded carry handle, so it is easy to move between rooms, campsites and parties. At 3.2 lbs (1.47 kg) it weighs noticeably less than the Zealot S39 at 5.2 lbs (2.34 kg). The catch: The published 20Hz-20kHz response is a generic rating, not measured bass extension; one 79mm driver cannot produce deep sub-bass, and an independent reviewer found the passive radiators stiff and leaking air, with bass ‘not that great’.
Buy the Zealot S39. It is rated higher for sound quality than the Zealot PT01 and costs less, which makes it the one to get unless you need something the other one does better.

The Two Speakers In Full
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.

Zealot PT01: $79.99 Zealot eBay
Pros: A compact 14.3 x 12.2 x 14.5 cm, 1.47 kg cube with a moulded carry handle, so it is easy to move between rooms, campsites and parties. A single 79mm full-range driver is fed by a claimed 30W amplifier and a 6000mAh battery, a large cell for this size, recharged over Type-C. Bluetooth 5.4 covers roughly 10m, and a ring of RGB lighting, a three-preset EQ and an optional handheld microphone cover casual outdoor listening and karaoke.
Cons: The published 20Hz-20kHz response is a generic rating, not measured bass extension; one 79mm driver cannot produce deep sub-bass, and an independent reviewer found the passive radiators stiff and leaking air, with bass ‘not that great’. No IP rating, runtime or charging time is given on the official spec sheet, so weather resistance and battery life remain unverified. No independent measurements exist.
