Preheat broiler. Remove tips from chicken wings - cut chicken wings in sections. Place wings on foil-lined baking sheet. Broil wing sections for 8-10 minutes until skin is crispy and golden. Place wings in slow cooker.
Mix preserves, taco seasoning, chipotle powder, garlic powder, ketchup and jalapeno pepper in a bowl. Pour over wings and stir to coat. (Note: chipotle can add heat with only a small amount)
Cover and cook on HIGH for 2-1/2 to 3-1/2 hours. Turn off slow cooker and let sit for 15 minutes to allow juices to thicken.
