Short answer: the ION Pathfinder 320, though neither ranks well in its class. It ranks #68 of 76 boombox speakers by sound quality, rated 2.2/5, at $129.99; the Zealot S78 ranks #76, rated 2.0/5, and costs $159.68, so there is not much of a tradeoff to weigh. Both are rated below 3.0/5 among the 76 boombox speakers, so if sound quality matters, consider the Tribit Stormbox Blast instead, ranked #2 at $179.99.
The case for the ION Pathfinder 320: 100 hour battery at low-moderate volume. The tradeoff: Bass is not as deep as competitors.
What the Zealot S78 does well: A robust 4.4kg party speaker with claimed 120W RMS output, IP67 protection, USB-C charging, a power-bank function, aux, USB and microSD playback, TWS pairing and multiple EQ modes. The tradeoff: At high volume, reviews report distortion and fluctuating level, so its headline power is more useful below its maximum setting.
Buy the ION Pathfinder 320. It is rated higher for sound quality than the Zealot S78 and costs less, so it is the default pick unless a specific strength of the other one matters more to you.
Battery life favors the ION Pathfinder 320: rated for 100 hours against 40 hours for the Zealot S78.

Zealot S78: $159.68 Amazon AliExpress eBay
Pros: A robust 4.4kg party speaker with claimed 120W RMS output, IP67 protection, USB-C charging, a power-bank function, aux, USB and microSD playback, TWS pairing and multiple EQ modes. Reviews find it very loud with useful bass and long claimed battery life, making it a credible choice for outdoor gatherings.
Cons: At high volume, reviews report distortion and fluctuating level, so its headline power is more useful below its maximum setting. It has no app-based EQ, and the bass and midrange refinement do not match better-established boombox speakers; assess its sound in person if tonal accuracy matters.
