Short answer: the Soundcore Boom 3i. It ranks #31 of 175 medium speakers by sound quality, rated 4.0/5, at $118.99. The W-King D320 ranks #51, rated 3.6/5, at $52.92, $66.07 cheaper, not enough of a saving to outweigh the sound-quality gap.
The Soundcore Boom 3i is the better-sounding, lighter pick. Looks to be designed as a direct competitor to the JBL Charge 5 with a very similar sound profile, warm tuned with boosted bass. At 1.7 lbs (783 g) it weighs much less than the W-King D320 at 3.1 lbs (1.4 kg). The tradeoff: Not quite as good as a JBL Charge 5, doesn’t go quite as loud or sound quite as balanced, but very very close.
The W-King D320 is the longer-running option. A 3.1 lbs (1.4 kg), IP67-rated travel speaker with claimed 40W output, USB-C charging, aux and microSD playback, speakerphone capability and an app with adjustable EQ. It is rated for 24 hours of battery against 16 for the Soundcore Boom 3i. It keeps a wired aux input, which the Soundcore Boom 3i lacks. The tradeoff: A single D320 is not stereo, and its warm balance trades away some detail and upper-treble air.
Buy the Soundcore Boom 3i. It is rated higher for sound quality, and saving $66.07 with the W-King D320 does not make up for the sound-quality gap.

Cons: Not quite as good as a JBL Charge 5, doesn’t go quite as loud or sound quite as balanced, but very very close. An earlier firmware version had some bass distortion, update your firmware in the Soundcore App

W-King D320: $52.92 AliExpress $52.92 eBay
Pros: A 1.4kg, IP67-rated travel speaker with claimed 40W output, USB-C charging, aux and microSD playback, speakerphone capability and an app with adjustable EQ. Owner reports praise its loud, deep-for-size bass and long runtime, while its two tweeters and passive radiators make it a capable choice for casual outdoor listening.
Cons: A single D320 is not stereo, and its warm balance trades away some detail and upper-treble air. The claimed 100Hz low-frequency specification suggests that its perceived bass should not be mistaken for true sub-bass; evaluate its tuning with the app rather than expecting a neutral default.
