A small appliance is typically a portable or semi-portable machine, generally used on countertops, tabletops, or other platforms, to accomplish a household task. Examples include blenders, toasters, coffee makers, microwaves, and electric kettles. These appliances are usually small enough to be easily moved and stored when not in use, and they are designed for specific tasks in the kitchen or around the home.

If you provide a list of options, I can help identify which one is a small appliance. For example, if the options are:

1. Refrigerator
2. Blender
3. Dishwasher
4. Oven

The small appliance in this list would be the blender, as it is portable, used on countertops, and designed for a specific task (blending food). The other items (refrigerator, dishwasher, and oven) are considered large appliances due to their size and fixed installation. Let me know if you'd like further clarification!
