Preheat oil in a large skillet over medium-high heat.
Combine chili powder, salt, and cayenne pepper. Season both sides of pork chops generously with spice mixture.
Add chops to the pan and cook 2 minutes per side until outside is brown. Combine juice or cider, maple syrup, and vinegar. Reduce heat to medium.
Add maple syrup mixture to pan. Scrap up any browned bit on the bottom of the pan. Continue to cook for 5-7 minutes more, turning chops to coat, until pork chop juices run clear and glaze has thickened.
