This is a USB hub with 7 USB 3.0 ports. It has a dedicated charging port, but the DC5V input AC adapter is missing. I confirmed that power is being supplied, but it's weak, so it might not be usable as a proper charging port. By the way, the AC adapter seems to be about 4mm in outer diameter? I apologize if I'm mistaken. The hub works properly, and I've confirmed that the on/off function is usable. The USB-TypeA connector on the PC connection side is slightly rusty, but there are no problems with its use. It's USB 3.0, so it's capable of high-speed communication up to 5Gbps. The cable is around 50cm long.
