Short answer: the W-King D320. It ranks #51 of 175 medium speakers by sound quality (rated 3.6/5) at $52.92 and is still sold new; the JBL Charge Essential ranks #92 (rated 3.2/5) and is discontinued, so it is only an option used. The JBL Charge Essential’s replacement, the JBL Charge Essential 3 SE, is rated 3.7/5 at $199.95.
The W-King D320 is the better-sounding pick. 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 keeps a wired aux input, which the JBL Charge Essential lacks. It has an adjustable EQ, which the JBL Charge Essential lacks. It charges over USB-C rather than Micro USB. The tradeoff: A single D320 is not stereo, and its warm balance trades away some detail and upper-treble air.
The JBL Charge Essential is the lighter option. Doubles as a power bank. At 1.7 lbs (770 g) it weighs much less than the W-King D320 at 3.1 lbs (1.4 kg). The tradeoff: Less clarity than the JBL Flip 4, highs rolled off.
Buy the W-King D320. It is rated higher for sound quality, and the JBL Charge Essential is discontinued, so it is only available used.

The Two Speakers In Full
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.
