My 160 watt black web speaker won’t charge, only plays with power cord attached. It says battery low as soon as its unplugged and then shut off. And yes I have reset it.

Hi Joseph, That might indicate a faulty battery. If you’re comfortable with electronics: Open the speaker and measure the voltage of the battery. Li-ion batteries don’t take deep discharging well, if the voltage on a 3.6 V battery drops below 1,5V it has probably died. Regards, Eelco
