Short answer: the Teufel Rockster Go 2. It ranks #91 of 164 medium speakers by sound quality, rated 3.2/5, at $129.99. The LG Xboom Grab ranks #104, rated 3.0/5, at $104.99, $25 cheaper, not enough of a saving to outweigh the sound-quality gap.
The case for the Teufel Rockster Go 2: At 1.6 lbs (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. It plays in stereo from a single unit, unlike the LG Xboom Grab. Watch for: There is no companion app or 3.5 mm input.
The LG Xboom Grab is the longer-running option. 20 hour battery life: longer than the JBL Flip 7 or UE Boom 4. It is rated for 20 hours of battery against 15 for the Teufel Rockster Go 2. The tradeoff: Bass extension not as deep as the top speakers.
Buy the Teufel Rockster Go 2. It is rated higher for sound quality, and the $25 you would save on the LG Xboom Grab does not close the gap.

The Two Speakers In Full
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.
