UNDERSTANDING MICROWAVE WATTAGE: THE BASICS
Before we dive into whether 700 watts is sufficient, let’s understand what wattage means in the context of microwaves.

Wattage is essentially a measure of power output – the higher the wattage, the more cooking power your microwave has at its disposal.
For example, when we talk about the power of a 900-watt microwave oven, it’s important to note that it sits at the higher end of the domestic microwave spectrum.
While a 700-watt microwave, by comparison, falls into the lower-middle range of household microwave power.
COOKING POWER AND EFFICIENCY
Let’s break down what 700 watts means in practical terms:

1. Heating Speed
– Takes approximately 20-30% longer than 1000-watt models
– Requires adjustment of standard cooking instructions
– May need multiple heating cycles for dense foods
2. Energy Consumption
– More energy-efficient than higher-wattage models
– Lower electricity costs
– Smaller carbon footprint
For example, see the table below comparing microwave oven cooking times between the 700 watts and 1000 watts microwave ovens:
Food Item | 700 Watts Time | 1000 Watts Time |
Cup of Water | 2:30 mins | 1:45mins |
Frozen Meal | 6 – 7 mins | 4 – 5 mins |
Popcorn | 3 – 4 mins | 2 – 3 mins |

FAQ: EVERYTHING YOU NEED TO KNOW ABOUT 700-WATT MICROWAVES
How much extra time does a 700-watt microwave need?
A 700-watt microwave typically requires about 20-30% more cooking time compared to standard 1000-watt models. For example:
– If a recipe calls for 2 minutes in a 1000-watt microwave, cook for approximately 2.5-3 minutes in a 700-watt model
– Use this formula: (1000-watt time × 1.3 = 700-watt time).
What’s the main difference between a 700-watt and 800-watt microwave?
The primary differences are:
– Cooking time: 800-watt models are about 15% faster
– Energy consumption: 800-watt units use slightly more power
– Price: 800-watt models typically cost $20-30 more
– Size: 800-watt units are often slightly larger
Is there much difference between 700 and 900 watts microwave?
Below are some of the differences between a 700 and 900 watts microwave:
– Cooking time is about 25-30% longer in 700-watt models
– 900-watt microwaves handle dense foods better
– 900-watt units are typically larger and more expensive
– Better defrosting capabilities in 900-watt models
Difference between 700 watts and 1000 watts microwave?
Key differences include:
– Cooking time: 700-watt models take about 30-40% longer
– Size: 1000-watt units are generally larger
– Price: 1000-watt models cost significantly more ($50-100 difference)

Can I run a 700-watt microwave on a 1000-watt outlet?
Yes, absolutely. A 700-watt microwave:
– Draws less power than a 1000-watt outlet provides
– Is safe to use on standard household circuits
– Won’t overload typical kitchen wiring
Can a 700-watt microwave boil water?
Yes, but with longer times:
– 240ml (1 cup): 2-2.5 minutes
– 480ml (2 cups): 4-4.5 minutes
– 720ml (3 cups): 6-6.5 minutes
– Results may vary based on starting temperature
Can a 700-watt microwave cook popcorn and for how long?
Yes, with adjustments:
– Standard microwave popcorn takes 3-4 minutes (vs 2-3 minutes in higher-wattage models).
Typically, it may take around 2.5 to 4 minutes, depending on the specific brand and type of popcorn.
To prepare popcorn in a 700-watt microwave oven, you’ll likely need to increase the cooking time compared to higher-wattage microwaves.
It’s best to follow the instructions on the popcorn packaging and adjust the cooking time as needed based on your microwave’s wattage.
CONCLUSION
So, is 700 watts good for a microwave? The answer depends entirely on your specific needs and circumstances.
For many users, particularly those in small households or with light reheating needs, a 700-watt microwave provides an excellent balance of efficiency, cost-effectiveness, and functionality.
While it may require slightly longer cooking times, the energy savings and gentler heating process can be advantageous for many situations.
