This 9V Arduino Battery Connector is designed to make your Arduino project portable – removing the need for direct connection into an electrical wall outlet. With a 2,1mm male power plug on one side and a 9V snap connector battery clip on the other, you can take your Arduino projects into the world, powered by a powerful but efficient 9V battery.

For extra precautionary measures, the battery clip has a small piece of heat shrink tubing, which primarily insulates the open wiring, but also acts to maintain the heat, which can be particularly beneficial in the case of a short on the circuit.
