Short answer: the W-King D320. It ranks #51 of 175 medium speakers by sound quality, rated 3.6/5, at $52.92; the Tribit Stormbox Flow ranks #62, rated 3.5/5, and costs $79.99, so there is little reason to consider the other one.
The case for the W-King D320: 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 Tribit Stormbox Flow lacks. The catch: A single D320 is not stereo, and its warm balance trades away some detail and upper-treble air.
The Tribit Stormbox Flow is the lighter choice. Up to 30 hours of battery life: roughly double most rivals (~20-24 hrs with XBass on). At 1.4 lbs (657 g) it weighs much less than the W-King D320 at 3.1 lbs (1.4 kg). Watch for: Midrange and bass are weirdly recessed about 4db below 700Hz.
Buy the W-King D320. It is rated higher for sound quality than the Tribit Stormbox Flow and costs less, which makes it the one to get unless you need something the other one does better.

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.

Tribit Stormbox Flow: $79.99 Tribit $79.99 eBay
Same family: the Tribit Stormbox Micro 2 (smaller model, rated 4.5/5), the Tribit Stormbox Pro (larger model, ranked higher, rated 3.7/5) and the Tribit Stormbox Blast (larger model, rated 4.5/5). See every Tribit Stormbox generation.
Pros: Up to 30 hours of battery life: roughly double most rivals (~20-24 hrs with XBass on). IP67 rated with a loose handle for carrying/hanging. Pairs with a second Flow for stereo; USB-C port charges your phone too. Measured bass extension of 47Hz (-10dB).
Cons: Not stereo. Midrange and bass are weirdly recessed about 4db below 700Hz. You need xbass mode for it to not sound like a clock radio with missing bass. You also can’t turn up the bass enough in the custom EQ modes to get it neutral, so it will sound bass light. Firmware 1.2.3 fixes the distortion issues with xbass mode on, but bass still sounds wobbly and uncontrolled.
