Battery Snapper Connector 9V + DC Jack

The 9V Battery Snap Connector + DC Jack is an adapter that transfers 9 volts from a battery to a DC power plug, allowing you to power a DC barrel jack with 9 volts.

To use this device, simply connect a standard 9-volt battery to the battery holder slot of the adapter. When inserted correctly, the battery’s voltage will be routed to the DC power plug. This cable serves as a 9V battery button power connection for Arduino projects. Note that the outer connector is negative.
