Short answer: the Teufel Rockster Go 2, if you are buying new. The JBL Charge 3 measures as well as it (#77 vs #80 of 150 medium speakers, 3.2/5 vs 3.2/5) but is discontinued, so only consider it used; the Teufel Rockster Go 2 is still sold new at $129.99.
What the JBL Charge 3 does well: Doubles as a 6000mAh power bank for USB devices. ~20 hour battery life. The catch: Less clarity than the Flip 4.
The case for the Teufel Rockster Go 2: At 0.74 kg, the IP67 Rockster Go 2 is genuinely easy to carry, and its claimed 28-hour battery life, USB-C fast charging, stereo pairing, and tripod mount suit outdoor use. Watch for: There is no companion app or 3.5 mm input.
Buy the Teufel Rockster Go 2 new; the JBL Charge 3 is no longer sold new, so it only makes sense as a used find.

Teufel Rockster Go 2: $129.99 Amazon eBay
Older model: the Teufel Rockster Go (ranked lower, rated 2.6/5).
Pros: At 0.74 kg, the IP67 Rockster Go 2 is genuinely easy to carry, and its claimed 28-hour battery life, USB-C fast charging, stereo pairing, and tripod mount suit outdoor use. Independent listening found a balanced, clear midrange and tuneful bass at sensible levels.
Cons: There is no companion app or 3.5 mm input. Reviewers found it loses some definition at maximum volume, and the claimed battery figure is optimistic for loud outdoor playback.
