Short answer: the W-King X20S. It ranks #30 of 91 boombox speakers by sound quality (rated 3.8/5) at $150.99 and is still sold new; the JBL Boombox 2 ranks #40 (rated 3.5/5) and is discontinued, so it is only an option used.
The case for the W-King X20S: Clearer and smoother than the larger W-King X20 at about half its size and weight, and in side by side tests it held its own against the Harman Kardon Go + Play 3, with nicer, more exposed mids and more volume. Watch for: Less bass and depth than the X20 and about 3dB quieter, and at maximum volume its mids and highs start to drown out the bass.
Why pick the JBL Boombox 2: 24 hour battery life (default volume); 20+ hours even at 60% volume. The catch: Somewhat bass heavy and boomy.
Buy the W-King X20S. It is rated higher for sound quality; the JBL Boombox 2 is no longer sold new.

W-King X20S: $150.99 AliExpress W-King eBay
Pros: Clearer and smoother than the larger W-King X20 at about half its size and weight, and in side by side tests it held its own against the Harman Kardon Go + Play 3, with nicer, more exposed mids and more volume. 140W RMS (180W peak), IPX7, Bluetooth 5.4, a built-in microphone, TF card, USB and aux playback, FM radio, a carry handle and a shoulder strap.
Cons: Less bass and depth than the X20 and about 3dB quieter, and at maximum volume its mids and highs start to drown out the bass. With a flat EQ the bass is cut off, so it needs the bass boost. The JBL PartyBox Encore Essential 2 sounded better in a direct comparison. Sold direct from W-King in the US.
