Buy the Xiaomi Sound Outdoor. 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.
There is a real battery-life gap here: the Tribit Stormbox Flow is rated for 30 hours, the Xiaomi Sound Outdoor only 12 hours.

The Two Speakers In Full
Tribit Stormbox Flow: $79.99 Tribit eBay
Smaller model: the Tribit Stormbox Micro 2 (rated 4.5/5).
Larger models: the Tribit Stormbox Pro (ranked higher, rated 3.7/5) and the Tribit Stormbox Blast (rated 4.5/5).
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.

Xiaomi Sound Outdoor: $54.99 Amazon eBay
Pros: Xiaomi Sound Outdoor uses 20W woofer, 10W tweeter + 2x passive radiators. Its 597 g, claimed 12 hours (Manufacturer specified) battery life, IP67 protection and mono playback make it a practical option for its intended room or portable use. A decent sounding speaker for its size.
Cons: Its 60Hz to 20kHz (Manufacturer specified) specification points to limited deep-bass reach for the cabinet size. There is no companion app. No EQ adjustment. Boosted bass that gets somewhat uncontrolled at high levels.
