Short answer: the Xiaomi Sound Outdoor. It ranks #44 of 150 medium speakers by sound quality, rated 3.7/5, at $54.99; the Teufel Rockster Go 2 ranks #80, rated 3.2/5, and costs $129.99, which makes this an easy call rather than a real tradeoff.
The case for the Xiaomi Sound Outdoor: Xiaomi Sound Outdoor uses 20W woofer, 10W tweeter + 2x passive radiators. The catch: Its 60Hz to 20kHz (Manufacturer specified) specification points to limited deep-bass reach for the cabinet size.
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. The catch: There is no companion app or 3.5 mm input.
Buy the Xiaomi Sound Outdoor. It is rated higher for sound quality than the Teufel Rockster Go 2 and costs less, so it is the default pick unless a specific strength of the other one matters more to you.

The Two Speakers In Full
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.

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.
