The specific features and attachments of a 2-in-1 blender can vary depending on the brand and model. Some common features you might find in a 2-in-1 blender include:

1. Blending Pitcher: A large container with a blade assembly used for making smoothies, shakes, purees, and other blended beverages.
2. Food Processor Attachment: This attachment usually comes with a different blade set and a smaller container for chopping vegetables, nuts, or other food items.
3. Variable Speed Settings: Most blenders offer different speed settings to control the blending process and achieve the desired consistency.
4. Pulse Function: The pulse function allows short bursts of blending to have better control over the blending process, especially when dealing with chunky ingredients.
5. Motor Power: The motor power can vary from model to model. Higher motor power generally means better performance when handling tough ingredients.
6. Interchangeable Blades: Some 2-in-1 blenders come with interchangeable blades, allowing you to switch between blending and processing tasks more easily.

Before purchasing a 2-in-1 blender, consider your specific needs and the types of tasks you want to perform with it. Look for reputable brands, read reviews, and compare different models to find one that suits your requirements and budget best.
