I purchased this item new, but it has the following issues: When I connect a cable to the charging port to supply power, the device turns on, can connect to a phone or PC, and sound comes out. However, the power immediately cuts off the moment I unplug the cable. I believe there is a problem with the rechargeable battery or the charging circuit. I only confirmed the operation, and the exterior is clean. It's a waste to throw it away, so I'm offering it to someone who can use it for parts, etc. Stored in a smoke-free environment, no pets. This is a junk item. Please do not purchase if you do not understand the meaning of "junk." Other features: Junk
