What Sony Accessory Is This?

Question

I found a Sony accessory. It's round and the color is gray. It can be opened and inside is a roll of cable. the end of the cable is a USB plug which is clipped at the bottom of the cover. The roll can be detached from the cover which has tiny rubber suctions at its base. It may look like a paper weight from a distance. Can anybody help me identify this Sony Accessory??????
