Short answer: the Sony SRS-XG500 for battery life, the Teufel Boomster 2021 for tonal balance. The Sony runs 30 hours, gets 3 hours from a 10-minute quick charge, and stops charging at 90% to extend battery longevity, but its upper bass is thuddy and it will not hold max volume without turning itself down. The Teufel is pretty balanced and slightly warm, with boosted mid bass covering for shallower bass.
What the Teufel Boomster 2021 gets right: Pretty balanced sound, slightly warm. The catch: Not as deep of bass as above ranked speakers. Boosted mid bass compensating for the lack of bass extension.
Buy the Teufel Boomster 2021 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.
