Short answer: the Yeahbox Sonic Boom Max 3 on paper, the JBL Partybox On the Go for tested basics. The Sonic Boom Max 3 claims 200W RMS (300W peak) from a true 3-way, 5-driver array, but those specs are manufacturer claims from a budget brand with limited independent testing. The On the Go ranks #46 of 75 against #40 of 75, includes a wireless microphone, and has a poor water rating at $300 against $206.09.
The case for the JBL Partybox On the Go: Included wireless microphone. The catch: Poor water rating.
What the Yeahbox Sonic Boom Max 3 gets right: 200W RMS (300W peak) true 3-way, 5-driver array. Set against that: A budget import brand with limited independent testing - specs are manufacturer-claimed.

Yeahbox Sonic Boom Max 3: $206.09 Amazon eBay
Pros: A large 3-way, 5-driver party speaker with claimed 200W RMS output, a 111Wh battery, USB-C fast charging, app EQ, TWS pairing, and aux, USB and microSD playback. Listener comparisons describe powerful bass, strong output and decent mids and highs for outdoor party use.
Cons: There is limited independent testing and the water/dust rating is reported inconsistently across listings. Listener comparisons find it less clear and refined than stronger boombox rivals, so its big bass and output are a better fit for parties than critical listening.
