The item you are describing is a Halogen Convection Oven, a popular countertop appliance known for its speed and versatility.1

The description "20L 8 In 1 Halogen Oven Machine - Color Black" highlights the key features of this type of cooker:

• Halogen Heating Element: Uses a powerful halogen light to instantly generate heat.2 This cooks food quickly, often 2-3 times faster than a conventional oven.3

• Convection Fan: A built-in fan circulates the hot air and infrared radiation evenly around the food.4 This results in fast, even cooking and crisp, well-browned results.5

• Healthy Cooking: Many models are promoted for allowing you to cook with little to no oil, similar to an air fryer, making it a healthier option for many foods.6

• 20 Liters (L) Capacity: This is the internal volume of the glass bowl. It's a generous capacity for a countertop appliance, large enough to cook a whole chicken, small turkey, or a good-sized roast.

• Extender Ring: Many models include an accessory called an extender ring, which can be placed on top of the main glass bowl to increase the capacity, often up to about 25 liters, allowing you to cook larger items or multiple layers of food.7

The "8 in 1" typically refers to the various ways you can prepare food in the oven, replacing multiple single-function appliances.8 These functions commonly include:

1. Roast: For meat, chicken, or vegetables.9

2. Bake: For cakes, cookies, and bread.

3. Grill/Broil: For browning, toasting, or quickly cooking thin cuts of meat.

4. Air Fry: Using the convection feature to cook chips, chicken wings, etc., with minimal oil.10

5. Steam: Using water and a steaming tray (often an accessory).11

6. Fry (with little to no oil): Similar to air frying.12

7. Defrost: Quickly and evenly defrosting food without cooking it.

8. Toast/Sear: Quickly crisping the surface of food.

• Color Black: Refers to the color of the oven's lid/heating unit and base. The cooking bowl itself is transparent glass.13

• Controls: Usually features an adjustable temperature dial and a timer dial (often up to 60 minutes).14

• Easy to Clean: The main cooking bowl is usually made of removable glass for simple cleaning.15

• Accessories: Standard sets typically include:

  • High and Low cooking racks (to allow for two-tier cooking)16

  • Tongs (for safely removing the hot racks and food)

  • Extender ring

  • Lid holder (for resting the hot lid).17
