iSunnao Bluetooth Car Kit Music Audio Receiver

It says it only has a run time of 8-hours. Any word on what kind of battery or if it’s rechargeable?

Amazon page seems to say it charges over USB. One review also mentioned it will not receive Bluetooth Signal when charging and only works when running from the battery.

Worked pretty well for about 2 months and then broke apart. The “run time” is only about 2 hours before needing to be charged.

It is a rechargeable battery.

This thing works, but that’s it. It runs about 2 1/2 to 3 hours that’s it. It will not play in charge at the same time. Basically it sucks
