What microwave wattage do I need? A 1,000-watt microwave will cook quickly and efficiently, so that's a great baseline. Microwaves with 700 watts or less are slower and may not cook evenly. In general, the higher the wattage, the faster the cooking time.
An 800 watt microwave should be powerful enough for most uses. Most microwaves on the market today are rated between 600 to 1100/1200 watts. The higher the watts the faster your food will cook. A lot of recipes for microwave cooking will often require at least 800 watts of power to ensure the food cooks evenly.
Most hair dryers will have a power rating label to indicate the maximum wattage, which typically ranges from 800 to 1800 watts. The energy use of a typical hair dryer first depends on which model it is using. Unheated air can use as few as 70 watts of power, but a hairdryer on high heat will use around 1500 watts.
How much electricity do household items use?
| Heating |
|---|
| 100 watts | Floor or box fan (high speed) |
| 90 watts | 52" ceiling fan (high speed) |
| 75 watts | 48" ceiling fan (high speed) |
| 55 watts | 36" ceiling fan (high speed) |
A 900 watt microwave should give you a good amount of cooking power which should result in food that is cooked quickly. Most microwaves are rated between 600 – 1100 Watts. At 900 watts you should be able to cook and heat up your food relatively quickly.
Be sure to know what kind microwave you have because a 700-watt cooks slower than a 1,000-watt. Just a FYI, the popcorn button setting on your microwave should be used with caution (or not at all.) (If you're still insisting on using the popcorn button, proceed with caution and keep an eye on it so it doesn't burn.)
An average modern microwave will use around 1200 watts. Click calculate to find the energy consumption of a microwave oven using 1200 Watts for 30 minutes a day @ $0.10 per kWh. In addition to using energy while cooking or heating, a microwave will also use 2 to 7 watts of power while in standby mode.
If you are looking for a good countertop microwave, you can expect to spend between $150 – $200 for a good microwave. A good microwave will have a large cubic footprint, high wattage, and a number of features. However, just because it is expensive, doesn't make it good.
A 1,000-watt microwave will cook quickly and efficiently. For example, a recipe recommending 5 minutes of 1,100-watt cooking time would only need to be increased by 30 seconds in a 1,000-watt oven.
Microwaves that don't have inverter technology have to switch between using 100 per cent and 0 per cent power when you choose 50 per cent power, whereas a microwave with inverter technology uses 50 per cent power the entire time so your food is more evenly defrosted and cooked.

If you use a 20-amp circuit, the maximum watts is 1,920 so that would be enough for a 1,000-watt microwave oven. Further, if you have a 1,500-watt microwave oven, it will use about 2,550 watts at full capacity. For a microwave oven of that power, you are going to need a 30-amp circuit.
Appliance Electricity Usage
| Appliance | Typical Consumption Per Hour | Cost Per Hour (at 10 cents per kilowatt-hour) |
|---|
| Water pump | 3,000 watts | 30 cents |
| Space heater | 1,500 watts | 15 cents |
| Hair dryer | 1,200 watts | 12 cents |
| Electric range burner | 1,000 watts | 10 cents |
Powering a Deep Freezer, Microwave, Electric Grill or Electric Stove. The typical electric range with 8” elements will use all 2000 watts if you use it while connected to the generator. Even better is using a slow cooker (300 watts), whereas an electric grill will use 1700 watts of the generator's power.
This works out to about 12 amps at 120 volts. How many amps does a 700 watt microwave use? 700W is the rated power of the microwave.
As a rule of thumb, microwaves are about 60% efficient so you need at least 1200w to safely use a 700w microwave. Ideally you want an inverter that provides at least 2000w constant not peak.
At this size/capacity (20 litres) 700 watts (with 7 power levels) is more than enough to produce a microwave that does its job very well.
When choosing an inverter, you need one that can accommodate the start-up draw. A 2,000-watt (running watts) inverter may have a peak (or surge) output of 3000 watts. This inverter could easily handle both the 900 running watt and the 2,700-watt surge (starting draw) requirements of your microwave.
Coffee makers, food processors, microwaves, and the like are easy to unplug but not so easy on the power grid. See the digital clock on your coffee maker and microwave? That clock means it's using energy. So if you don't need to know the time at opposite ends of the counter, go ahead and unplug.
The main difference between a 900-watt microwave and a 1000-watt microwave is how long it takes to cook food items. According to Microwave Cooking For One, it normally takes a 900-watt microwave longer to heat up something than a 1000-watt microwave.
What does a Watt mean? The Wattage of the light is the amount of energy it takes to produce a certain amount of light. The higher the wattage, the brighter the light, but also the more power it uses. 100 Watt incandescent lamp produces 1700 – 1800 lumens and uses 100 Watts of energy per hour.
50% power is synonymous with power level 5, medium, medium-low, and in some instances, defrost. However, if the microwave has only one setting, you can prepare the product on high for half the amount of time.
Use a medium-high setting (70 percent power) for simmering stews. Use a medium setting (50 percent power) for baking bread, cakes and muffins, and cooking less tender cuts of meats. Remove food from packaging before defrosting in your microwave.
| Common Appliances | Estimated Watts |
|---|
| Keurig | 1500 (max) 200-400 (continuous) |
| Blender | 300-1000 |
| Microwave (600-1000 Watt Cooking Power) | 1000-2000 |
| Waffle Iron | 800-1500 |
In short, both wattage ratings matter. The input wattage of the microwave oven pertains to the electrical circuit design and circuit requirements for the microwave oven, whereas the output wattage of the microwave pertains to how powerful it is for cooking and heating.
It can, however, be turned on and off, and that's exactly what power levels do. When you lower the power level in a microwave oven, you decrease the amount of time the magnetron stays on. To see this phenomenon in action, we grabbed some LED light bulbs (which also respond to microwaves) and did some experimenting.
Domestic fridge power consumption is typically between 100 and 250 watts. Over a full day, a fridge is likely to use between 1 to 2 kilowatt-hours (kWh).
