Preheat the oven to 350 degrees F. Spray a 10 1/2 by 5 1/2 by 3 inch loaf pan with nonstick cooking spray. Line the loaf pan across the short length with a sheet of parchment paper so there is 1 inch over hang on either side.

Whisk the flour, baking soda, salt, baking powder, and cinnamon in a medium bowl to blend. Whisk the sugar, oil, eggs, and vanilla in a large bowl until fulling incorporated. Stir in the banana. Add the dry ingredients and chocolate chips and fold them in just until blended. Do not over mix.

Pour the batter into the prepared pan and bake for 1 hour and 5 minutes or until a toothpick inserted in the center comes out clean. Allow to cool for 30 minutes in the pan before removing the loaf to a wire rack to cool completely.
