Soundboks 4 is tied for the loudest battery-powered speaker on this site, but costs nearly ten times as much as the Onn Large Party gen 2. They rank 19 of 51 and 29 of 51.
Soundboks 4’s removable 40-hour battery and high-efficiency drivers make it tied for the loudest battery speaker here, though it’s very large, not stereo, and not as neutral or deep-bassed as the JBL Partybox lineup.
Onn Large Party gen 2 costs a small fraction of the price with karaoke mic/guitar inputs and wheels of its own, though Consumer Reports found its bass boomy and treble smeared.
Buy the Soundboks 4 if you specifically need its extreme max volume and removable-battery ecosystem for outdoor events. Buy the Onn Large Party gen 2 for a small fraction of the price.
There is a real battery-life gap here: the Soundboks 4 is rated for 40 hours, the Onn Large Party gen 2 only 12 hours.

The Two Speakers In Full
Onn Large Party gen 2: $129 Walmart eBay
Pros: A remarkably full-featured, manageable 9.5kg party speaker: wheels and handle, FM radio, aux, USB-A charging, mic and guitar inputs with karaoke echo, and Party Sync. Independent testing confirms bass with real impact and enough output for a large room; it is a clear improvement over the Gen 1 for low-end weight.
Cons: The low price shows in the refinement. Consumer Reports found boomy bass, hazy/grainy mids, a prominent smeared treble and a narrow, two-dimensional soundfield; it also notes distortion or other audio issues. There is no app or EQ to tame the tuning, and IPX4 only covers splashes rather than rain or immersion.
