Short answer: the Sony SRS-XG500 for battery, the Soundcore Motion Boom+ for its driver array. Sony’s 30-hour battery and 10-minute quick-charge for 3 hours are the draw at $399.99, though its upper bass is thuddy and not as deep as others. The Soundcore packs 80W of stereo from dual 30W woofers and dual 10W titanium tweeters at $122.42, but its default presets are warm with rolled off treble.
Buy the Sony SRS-XG500 only if you find one used in good condition; both are discontinued, and it is the better rated of the two. For a new speaker, start with the Tribit Stormbox Blast instead.

Soundcore Motion Boom+: $122.42 after $40 coupon Discontinued Amazon eBay
Newer model: the Soundcore Boom 2 Plus, ranked higher, rated 3.6/5.
Pros: 80W stereo from dual 30W woofers + dual 10W tweeters with titanium drivers for treble clarity. 13,400mAh battery for 20 hours (12-15 at high volume). IP67 waterproof, floats, rugged build inspires confidence. Bluetooth 5.3 multipoint pairing, Soundcore app EQ, PartyCast 2.0 mode. USB-C input, USB-A output for powerbank. Measured bass extension of 52Hz (-10dB).
Cons: Default presets are all warm sounding with rolled off treble. Will need a custom EQ to get closer to neutral. A shrill sounding 6kHz peak comes out when volume is above about 60%. Not much deeper bass than a Motion Boom and a lot less deep bass than other speakers in the class. Discontinued.
