Microwaves have become a kitchen staple, offering convenience and speed in cooking and reheating food. When shopping for a new microwave, one of the key specifications you’ll encounter is wattage. Two common wattage levels are 700W and 800W. But does that seemingly small 100-watt difference actually matter in your daily cooking routine? Let’s delve deep into the nuances of microwave wattage and uncover the real-world implications.
Understanding Microwave Wattage
Microwave wattage refers to the amount of power the appliance uses to generate microwaves, which then heat the food. Higher wattage generally translates to faster cooking times. Think of it like horsepower in a car – more power means quicker acceleration. However, wattage isn’t the only factor determining cooking performance. Other aspects like microwave distribution and overall design also play a role.
The Role of Wattage in Cooking Time
As a general rule, a microwave with higher wattage will cook food faster than one with lower wattage, assuming all other factors remain constant. This is because higher wattage means more energy is being directed towards heating the food in a given period.
A 700W microwave will take longer to heat the same item compared to an 800W microwave. This difference, however, may not always be as dramatic as you might expect. The actual time difference depends on the specific food item, its starting temperature, and the quantity.
Wattage and Cooking Evenness
While wattage primarily affects cooking speed, it can also indirectly influence cooking evenness. In some cases, lower wattage microwaves, with their longer cooking times, may allow for more even heat distribution, especially for delicate items that are prone to overheating. However, modern microwave designs often incorporate features like rotating turntables and advanced wave distribution systems to mitigate uneven cooking, regardless of wattage.

What is the primary difference between a 700W and 800W microwave oven?
The fundamental difference between a 700W and 800W microwave lies in their power output. Wattage indicates the amount of energy the microwave can generate and utilize to heat food. An 800W microwave, possessing a higher wattage, can produce more heat in the same amount of time compared to a 700W microwave. This directly impacts the cooking speed and efficiency.
Therefore, an 800W microwave will cook food faster and often more evenly. While the actual cooking time difference might seem small for short durations, it can become significant when heating larger portions or cooking more complex recipes. The higher wattage also allows for potentially better browning and crisping, although this depends on the specific microwave model and its features.
Will an 800W microwave cook significantly faster than a 700W microwave?
The difference in cooking speed between a 700W and 800W microwave, while noticeable, isn’t always dramatic. Generally, an 800W microwave will cook food approximately 10-15% faster than a 700W model. This translates to saving seconds or minutes, especially noticeable with larger quantities of food or when heating items that require longer cooking times.
However, the actual time difference can be influenced by factors beyond wattage, such as the food’s density, starting temperature, and the microwave’s design. Some advanced 700W microwaves might incorporate technologies that partially compensate for the lower wattage, narrowing the gap with simpler 800W models. Ultimately, while the 800W offers a quicker cooking experience, it’s not always a night-and-day difference.
Does the wattage difference affect the type of food I can cook in each microwave?
In most cases, the wattage difference between a 700W and 800W microwave won’t dramatically restrict the type of food you can cook in either. Both models are capable of handling everyday tasks like reheating leftovers, cooking popcorn, and defrosting frozen items. You can generally cook the same foods in either microwave; however, the required cooking time will vary.
The primary implication of the wattage difference lies in the cooking time adjustment. Recipes designed for higher-wattage microwaves will need adjustments when used in a lower-wattage model to ensure the food is cooked thoroughly without being overcooked. While an 800W microwave might offer slightly better performance for foods requiring higher temperatures or longer cooking times, like certain meats or casseroles, the 700W can still handle these dishes with adjusted cooking times.
Is an 800W microwave more energy-efficient than a 700W microwave?
The energy efficiency comparison between a 700W and 800W microwave is nuanced. While an 800W microwave consumes more power at any given moment due to its higher wattage, it often cooks food faster. This shorter cooking time means the total energy consumption for a specific task might be similar to, or even slightly less than, that of a 700W microwave.
However, energy efficiency also depends on how frequently the microwave is used and the types of foods being cooked. If you consistently reheat small portions that take only a minute or two, the difference in energy consumption between the two models might be negligible. In contrast, frequent users who cook larger meals might see a small energy saving with the 800W model due to the shorter cooking durations. The best way to know for sure is to compare the energy star rating of the models you are considering.
Are 800W microwaves typically more expensive than 700W microwaves?
Generally, 800W microwaves tend to be slightly more expensive than 700W models. This price difference often reflects the higher wattage and potentially the inclusion of additional features or enhanced build quality. However, the specific price range can vary widely depending on the brand, size, features, and overall design of the microwave.
You might find some 700W microwaves with advanced features or a premium design that are priced similarly to or even higher than basic 800W models. Therefore, it’s crucial to compare prices across different models and brands to determine the best value for your needs. The wattage is only one factor influencing the price, and considering other features and your budget is essential.
When would a 700W microwave be a better choice than an 800W microwave?
A 700W microwave might be a better choice when budget is a primary concern. As mentioned previously, 700W models tend to be more affordable, making them a suitable option for individuals or families looking to save money. If you primarily use a microwave for simple tasks like reheating leftovers or making popcorn, the slightly slower cooking time of a 700W model might not be a significant drawback.
Additionally, a 700W microwave can be preferable in situations where power consumption is a critical factor, such as in small apartments with limited electrical capacity or in off-grid living situations powered by solar panels. While the difference in energy usage might not be substantial in all cases, minimizing power draw can be beneficial in certain circumstances. If you are in a dorm room, you are likely limited to lower wattage devices.
How do I adjust cooking times when using a recipe designed for a different wattage microwave?
When using a recipe designed for a higher-wattage microwave in a lower-wattage model, you’ll need to increase the cooking time. As a general rule of thumb, you can increase the cooking time by approximately 10-15% for every 100W difference in wattage. So, if a recipe calls for 5 minutes in an 800W microwave, you would add roughly 30-45 seconds when using a 700W microwave.
However, this is just a guideline, and you should always monitor the food closely during cooking to prevent overcooking or undercooking. Start by adding a shorter time increment, such as 15 seconds, and then check the food’s temperature and consistency. Repeat this process until the food is properly heated. Remember that denser foods will require a more significant time adjustment compared to lighter, less dense foods.
