The characteristics of a small countertop water dispenser can vary depending on the specific model and brand. However, here are some common characteristics you may find:

1. Compact Size: Small countertop water dispensers are designed to be space-saving and compact, making them suitable for placement on kitchen countertops, office desks, or small areas where space is limited.

2. Water Dispensing Options: These dispensers typically offer multiple water dispensing options. They may have a push-button or lever system to dispense water in different quantities, such as a continuous flow or a specific volume per dispense.

3. Water Temperature Control: Some small countertop water dispensers provide temperature control features. They may have options for dispensing cold water, hot water, or room temperature water, depending on your preferences and needs.

4. Cooling and Heating Systems: Dispensers with temperature control often incorporate cooling and heating systems. The cooling system chills the water and maintains a cold temperature, while the heating system heats the water for hot beverages like tea or coffee.

5. Water Filtration System: Many small countertop water dispensers include built-in water filtration systems. These systems help remove impurities, such as chlorine, sediment, or odors, improving the taste and quality of the dispensed water.

6. Storage Capacity: The storage capacity of small countertop water dispensers can vary. They may have a built-in water tank or reservoir that can hold a certain volume of water, typically ranging from a few liters to several gallons.

7. Indicator Lights: Dispensers often feature indicator lights to provide information about the operating status. These lights may indicate when the water is being heated, cooled, or when the filter needs replacement.

8. Drip Tray: A drip tray is commonly included to catch any water spills or drips that may occur during the dispensing process. The drip tray helps maintain cleanliness and prevents water from reaching the countertop.

9. Design and Aesthetics: Small countertop water dispensers come in various designs and finishes to suit different preferences and interior styles. They can be made of plastic, stainless steel, or other materials, with options for different colors or patterns.

10. Ease of Use and Maintenance: These dispensers are designed for easy operation and maintenance. They often have user-friendly controls, removable water tanks or reservoirs for refilling, and filter replacement indicators to simplify the maintenance process.
