Encountered these when looking at the JBL Charge 3 deal. The Link 300 isn’t portable and is meant to be a home speaker but the smaller Link 20 is advertised with 10 hours of battery life, so less than the Charge 3 but it’s a smart speaker so it’s a bit of a different category than regular portable Bluetooth speakers.
