Short answer: the JBL Boombox 4 for measured output, the Bugani Boost Max for claimed power. The JBL has pretty insane output for its size with a 7-band EQ, but it is overpriced, sounds worse than the Boombox 3 out of the box and drops the aux input. The Bugani claims 240W stereo from dual 4 inch woofers and passive bass radiators, but has shallow bass, some midrange peaks and a poor water rating.
Buy the JBL Boombox 4. It is rated higher for sound quality; the Bugani Boost Max is no longer sold new.
There is a real battery-life gap here: the JBL Boombox 4 is rated for 28 hours, the Bugani Boost Max only 15 hours.

JBL Boombox 4: $549.95 Amazon B&H Photo Video eBay
Older models: the JBL Boombox 3 (ranked lower, rated 3.8/5), the JBL Boombox 2 (ranked lower, rated 3.5/5) and the JBL Boombox (ranked lower, rated 2.9/5).
Pros: Pretty insane output capability for the size. IP68 protection and Auracast pairing with other current JBL speakers. Measured bass extension of 41Hz (-10dB).
Cons: Pretty overpriced for the category. Better than the Boombox 3 mostly because there are more 7 EQ bands instead of just 3 and it can be better tuned. Try Oluv’s EQ for it. Out of the box sounds worse than the Boombox 3. No Aux input.
