Short answer: the Zealot S89. It ranks #19 of 98 boombox speakers by sound quality (rated 4.0/5) at $246.99 and is still sold new; the W-King H10 ranks #75 (rated 2.7/5) and is discontinued, so it is only an option used.
The Zealot S89 is the better-sounding, deeper-bass option. A 16.1 lbs (7.3 kg) boombox with a claimed 36Hz bass extension, 40-hour battery life, IPX6 protection, USB-C charging, aux, USB and microSD playback, TWS and multi-speaker PartyAdd. Its bass reaches about 36Hz before falling 10dB, against 54Hz for the W-King H10. It is rated for 40 hours of battery against 24 for the W-King H10. It links with other speakers (PartyAdd up to 100 speakers), which the W-King H10 cannot. The tradeoff: At high volume, listener reports describe the bass as loose or muddy and the overall balance as less clear than better boombox speakers.
The W-King H10 is the lighter pick. Comes with wireless microphone. At 7.1 lbs (3.2 kg) it weighs much less than the Zealot S89 at 16.1 lbs (7.3 kg). Watch for: Not very deep bass.
Buy the Zealot S89. It is rated higher for sound quality and still sold new, while the W-King H10 is discontinued.

Zealot S89: $246.99 Amazon $246.99 AliExpress $193.58 eBay
Pros: A 7.3kg boombox with a claimed 36Hz bass extension, 40-hour battery life, IPX6 protection, USB-C charging, aux, USB and microSD playback, TWS and multi-speaker PartyAdd. Listener comparisons find it capable of very high output and substantial bass for outdoor use. A great value for its bass, battery life and maximum volume. Measured bass extension of 36Hz (-10dB).
Cons: At high volume, listener reports describe the bass as loose or muddy and the overall balance as less clear than better boombox speakers. The heavy cabinet and basic finish also make it less polished for daily portability, while its multiple EQ modes cannot substitute for a genuinely neutral tuning.
