The Locking Tab is meant to be pushed upward into the power supply. Forcing the Locking Tab down will cause the plastic to snap.

To use the power supply, simply insert into the back of your Nintendo 64. The Locking Tab will click into place and prevents the power supply from being pulled out accidentally. Then connect a compatible Power Source to the USB-C connector on the power supply. The Power LED will light green when a compatible Power Source is connected.

To remove the power supply, disconnect the USB-C power cable, then insert your finger into the Pull Groove and pinch on the Locking Tab with your thumb. Pull the power supply directly out.

Do not power the USB-C power supply when not inserted in your Nintendo 64 as you could accidentally short the 6 Pin Connector and cause permanent damage to the power supply.
