Short answer: the Teufel Rockster Go 2, if you are buying new. The JBL Flip Essential measures as well as it (#87 vs #91 of 164 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.
The JBL Flip Essential is the lighter choice. A genuinely portable 1 lbs (471 g) speaker with IPX7 water resistance, a 3.5mm aux input and 16W output from two full-range drivers. At 1 lbs (471 g) it weighs noticeably less than the Teufel Rockster Go 2 at 1.6 lbs (735 g). It keeps a wired aux input, which the Teufel Rockster Go 2 lacks. The tradeoff: Bass is lighter than the Flip 5 and the 80Hz claimed low-frequency limit means it cannot deliver real low-end weight.
The Teufel Rockster Go 2 is the longer-running option. 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 is rated for 15 hours of battery against 10 for the JBL Flip Essential. It supports AAC Bluetooth, which the JBL Flip Essential lacks. It links with other speakers (Party Link, up to 100 speakers), which the JBL Flip Essential cannot. Watch for: There is no companion app or 3.5 mm input.
Buy the Teufel Rockster Go 2, since the JBL Flip Essential is discontinued and only worth hunting down used.

The Two Speakers In Full
JBL Flip Essential: $130 Discontinued eBay
Newer model: the JBL Flip Essential 2, ranked higher, rated 3.3/5.
Pros: A genuinely portable 471g speaker with IPX7 water resistance, a 3.5mm aux input and 16W output from two full-range drivers. It is a simple, no-app option for wired sources, travel and casual listening where its cylindrical shape and modest size are a genuine advantage.
Cons: Bass is lighter than the Flip 5 and the 80Hz claimed low-frequency limit means it cannot deliver real low-end weight. Battery life is only a claimed 10 hours, there is no speakerphone, EQ or party mode, and its older Bluetooth 4.1 platform and discontinued status make it a basic used-market choice.

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.
