5.5mm to 4.8mm barrel jack adapter

Convert a standard 5.5 mm barrel plug for use with a Sega Genesis Model 2. This compact 5.5 mm to 4.8 mm barrel jack adapter allows compatible center-positive power supplies to connect to the smaller power input used by the Genesis Model 2.

For Genesis Model 2 consoles only. Do not use this adapter with a Genesis Model 1, which uses a different center-negative power configuration.
