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.
Buy the Yeahbox Sonic Boom Max 3. It is rated higher for sound quality; the ION Pathfinder 4 is no longer sold new.
