These are not really the same size class, and that is the honest framing here. The Zealot PT21 ranks #12 of 46 party speakers by sound quality at $225.86; the JBL Eon One Compact ranks #15 of 16 battery-powered PA speakers by sound quality at $699.
The Zealot PT21 is the longer-running, tougher choice. Dual 166mm woofers and 200W output in a lighter, more compact body than the Zealot ZE41, with a bundled wireless microphone and echo effect built in for karaoke. It is rated for 60 hours of battery against 12 for the JBL Eon One Compact. It is rated IPX5, while the JBL Eon One Compact has no water resistance. It links with other speakers (PartyAdd up to 100 speakers), which the JBL Eon One Compact cannot. The catch: Unlike some other Zealot models, app-based EQ customization doesn’t appear to be fully supported yet, and IPX5 means it can handle splashes but not submersion.
The case for the JBL Eon One Compact: Professional 4-channel mixer with XLR/TRS preamps, phantom power for condenser mics. Watch for: Quite distorted at full volume.
Buy the Zealot PT21 at $225.86 for a party speaker, or the JBL Eon One Compact at $699 for a battery-powered PA speaker instead.

Zealot PT21: $225.86 AliExpress $225.86 eBay
Pros: Dual 166mm woofers and 200W output in a lighter, more compact body than the Zealot ZE41, with a bundled wireless microphone and echo effect built in for karaoke. Quite deep bass for the price, even deeper than the JBL Boombox 4 in direct comparisons.
Cons: Unlike some other Zealot models, app-based EQ customization doesn’t appear to be fully supported yet, and IPX5 means it can handle splashes but not submersion.
