This is an excellent speaker with full range speakers and good base response. Unfortunately, the speaker battery appears to be faulty in that it will not charge up higher than 75%. Even after two days on the mains charger, my current monitor showing that the Soundcore Boost is only drawing a trickle charge and the speaker indicator lights showing the speaker is fully charged, as soon as I unplug it, only three indicator lights show (50-75%).
Had problems with battery issues with the previous Anker A3143. I hope this isn’t going to be a problem with the Soundcore Boost, too!
