Add the oats, protein powder, chia or hemp seeds, nut butter, pitted dates (or maple syrup), sea salt, and cinnamon (if using) to a food processor.
Process until the mixture begins to combine, stopping to scrape down the bowl as needed; blend thoroughly so the dates break down and incorporate.
With the processor running, add 2 to 6 tablespoons of water a little at a time, processing between additions, until the dough holds together when pressed and resembles thick cookie dough (about 4 Tbsp is typical).
Add the mini chocolate chips and pulse just until they are distributed throughout the dough without fully pulverizing them.
Scoop or roll the dough into 16 equal-sized balls using a small cookie scoop or your hands, pressing firmly to shape each ball.
Place the power balls in an airtight container and store as desired.
