Short answer: the Bogasing G4. It ranks #25 of 150 medium speakers by sound quality, rated 4.0/5, at $38.29; the JBL Charge 4 ranks #56, rated 3.5/5, and costs $94.99, so there is not much of a tradeoff to weigh.
What the Bogasing G4 does well: A 0.83kg travel-friendly speaker with 50W output, IPX7 protection, USB-C charging, aux and microSD playback, LC3 Bluetooth and TWS pairing. The tradeoff: The upper treble is boosted and uneven, while the mids sit slightly behind the bass and highs, so it is not a neutral choice for vocal-focused music.
Why pick the JBL Charge 4: Doubles as a power bank for charging phones/tablets. The catch: Not stereo.
Worth knowing: the JBL Charge 4 is discontinued, though it still ranks #56 of 150 medium speakers by sound quality, so a used unit beats most of what is still sold new.
Buy the Bogasing G4. It is rated higher for sound quality than the JBL Charge 4 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
Bogasing G4: $38.29 Amazon eBay
Pros: A 0.83kg travel-friendly speaker with 50W output, IPX7 protection, USB-C charging, aux and microSD playback, LC3 Bluetooth and TWS pairing. It reaches a useful 100dB maximum level and has a measured 56Hz -10dB bass point, giving it more low-end presence than many speakers of this size. Measured bass extension of 56Hz (-10dB).
Cons: The upper treble is boosted and uneven, while the mids sit slightly behind the bass and highs, so it is not a neutral choice for vocal-focused music. It has no app or user EQ, and its Super Bass and Vocal modes offer little practical differentiation according to listening tests.
