Let us discuss in detail each feature of both appliances to gain a better understanding.

1. Technology Used

The technology that both OTG and microwave oven use, is different. An OTG uses heated coils (nickel or chromium) to heat the compartment within. It also has a fan that helps in the even distribution of heat inside.

This is How an OTG Works:


The coils (on the ceiling and roof) in the OTG help in converting the electricity into heat. Since the coil’s temperature impacts the heat generation, it may take more time to cook when compared to microwave ovens.

When it comes to the microwave oven, it uses electromagnetic waves to generate heat. It does not come with a pre-installed fan but has a rotating plate that helps in evenly heating the food from all sides.

This is How a Microwave Oven Works:

Convection Microwave Oven

The microwave uses high-frequency electromagnetic waves, also called microwaves. These waves pass through the food and increase its temperature, cooking it. As the food sits on the rotating plate, spinning around, the microwaves bounce back and forth from the metal walls and then penetrate the food. This facilitates the rapid heating of the food, making it hotter in lesser time.

Best Bet For

An OTG, as the name goes, Oven, Toaster, and Griller, is the best bet for baking, toasting, and grilling. It helps you bake professional-level cakes, grill meat, and toast bread quickly, easily, and comfortably. If you are looking for a dedicated device that performs all three tasks effortlessly, an OTG is all you need. Also, if you want to master your cake baking skills with world-class baking quality, you can never go wrong with an OTG.

On the other hand, a convection microwave oven does all the functions that an OTG performs. Besides that, an oven enables you to reheat, cook and also de-freeze the food, which an OTG does not. A microwave oven is the best option if you are looking for multi-purpose functionalities in a single appliance.

2. Capacity & Spacing

As mentioned earlier, an OTG offers maximum capacity, which is up to 60 litres. It has wide spacing and racks installed within that allow you to cook large batches of food simultaneously and hassle-free. It can accommodate large dishes with ease.

Whereas a microwave oven has a maximum capacity of around 32 litres. Moreover, it has limited space with a rotating plate that does not make it feasible to cook a large quantity of food. Not only that, because of its compact setup, it allows you to put one thing at a time.

Although an OTG has a higher capacity, it is lightweight, as opposed to a microwave oven.

3. Temperature

Both OTG and oven have a similar temperature range. However, the time each device takes to pre-heat is different. While an OTG consumes around 15 minutes to pre-heat, an oven takes just five minutes for the same. If you consider this feature, your cooking time is decreasing.

4. Power Consumption

When it comes to power consumption, an OTG utilizes less electricity when compared to a microwave oven. However, the amount of power an OTG consumes differs as per the usage of the appliance.

The bigger the volume, the larger the power consumption will be. While the bigger models consume more power (around 1800 W), the smaller ones tend to consume less, which is about around 1200 W. If you are a family that does not do much baking or grilling, a smaller model with low power consumption will suffice.

The average range of power consumption for a microwave oven falls somewhere between 800 W to 3000 W. An oven with a capacity of 28 litres may consume approximately 2900 watts of power.

5. Ease of Use

An OTG has mechanical temperature controls and settings that can be confusing for the user to operate.

Whereas a microwave oven has an LCD panel for temperature control that offers higher user-friendliness. You just choose the settings (low, medium, or high), and the appliance adjusts

automatically to the pre-set temperature and time.

6. Price

An OTG is less expensive when compared to a microwave oven. A 42-litre capacity OTG would cost you around Rs. 10,000, whereas a 30-litre capacity oven costs you about Rs. 16,000.

7. Choice of Utensils

An OTG offers great versatility when it comes to using utensils of various metals inside. You can use aluminium, glass, and silicone utensils in an OTG.

Whereas in a microwave oven, you cannot use metal vessels but only those made of plastic, silicone, and glass.

8. Food Preparation Time

The time taken by OTGs to prepare food is comparatively more than microwave ovens. They have a slow cooking nature that helps in cooking the food uniformly. Such kind of cooking is perfect when baking cakes, cookies, cupcakes, bread, and pasta, etc.

Coming to the microwave ovens, they have less pre-heating time as well as food preparation time. Because of their quick-heating abilities, they are perfect for re-heating and cooking instantly.

9. Weight

Despite having a larger capacity, an OTG weighs less and makes it very easy for portability.

On the other hand, microwave ovens are heavy, making them less portable devices.

10. Baking Quality

OTGs are undoubtedly, and undeniably the best choice if you want to take your baking skills to the next level. It guarantees world-class baking quality when preparing recipes.
