Short answer: the ION Pathfinder 4 for battery life; the Yeahbox Sonic Boom Max 3 on manufacturer-claimed output. The ION runs about 100 hours at low-moderate volume, though its bass is not as deep as competitors. The Yeahbox claims a 200W RMS (300W peak) true 3-way, 5-driver array, but it is a budget import brand with limited independent testing.
What the ION Pathfinder 4 gets right: ~100 hour battery life at low-moderate volume. The catch: Bass is not as deep as competitors.
On the Yeahbox Sonic Boom Max 3 side: 200W RMS (300W peak) true 3-way, 5-driver array. The catch: A budget import brand with limited independent testing - specs are manufacturer-claimed.
Buy the Yeahbox Sonic Boom Max 3. It is rated higher for sound quality than the ION Pathfinder 4 and costs less, which settles it without a real tradeoff to make.

The Two Speakers In Full
ION Pathfinder 4: $300 eBay
Pros: A feature-heavy 11kg party speaker with claimed 120W output, a very long 100-hour battery rating at moderate volume, FM radio, USB playback, aux and microphone inputs, lights, USB-C charging and a Qi charging pad. It can pair with a second unit for stereo, making it useful for long outdoor events where convenience matters more than fidelity. Measured bass extension of ~62Hz (-10dB).
Cons: Its roughly 62Hz -10dB bass extension is shallow for a speaker this large, so it does not deliver the deep impact of better party-speaker rivals. The heavy enclosure is cumbersome to carry, IPX5 only protects against sprays, and its simple high/low tone controls cannot provide the precision of a full app EQ.

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.
