Onn Wireless Bluetooth Speaker Won T Turn On Unless Plugged Bluetooth Speaker

Chosen Solution

I have the Onn. Medium Party Speaker with LED Lighting. It’s supposed to be a wireless Bluetooth speaker. It is fully charged but won’t turn on unless it’s plugged in.

That’s normal, my Bluetooth headphones (Sony) do the same thing. I don’t know why but I think it’s supposed to be that way.

Hey this is most commonly a battery issue. If you left it discharged or did not use it for a while, it is possible that the battery dropped below a threshold voltage. What happens than is the BMS(Battery management system) can prevent the battery from charging as it has dropped below what’s considered a safe level. This essentially cuts off the battery from your device, resulting in the symptoms above. Your device will work when plugged in and will commonly show full battery when trying to charge as there will be no battery to charge.
