USB power cable for game consoles! Compatible with: * Famicom * Super Famicom * PC Engine * Core Grafx Operation has been confirmed with my beloved Famicom and Super Famicom, etc. Various manufacturers sell USB power cables, but I feel that this manufacturer's cable is the most stable. \* Please use a USB power adapter with a rating of 2.1A or higher! \* The terminal is center-negative, so please do not use it with game consoles other than those listed here. Thank you. Multiple units in stock. Thank you.
