Can I Run a Small Microwave on An Inverter?

A microwave oven is a kitchen appliance that many of us use on a daily basis. But what happens when there is a power outage and your oven is not working? Can I run a small microwave on an inverter? Yes, you can run a small microwave on an inverter. In fact, many people do just that.

An inverter is a device that changes 12V direct current (DC) to 110V, 120V, or 240V alternating current (AC). This means that you can use your microwave oven even when there is no power. All you need is an inverter and a power source, such as a car battery.

Inverters are available in different sizes and wattages. The size and wattage you need will depend on the size of your microwave oven.

When choosing an inverter, make sure to get one that has a clean sine wave. This will ensure that your microwave oven will work fine and smoothly.

What Size Inverter Will Run a Small Microwave?

The size of the inverter will be determined by the wattage of the microwave. Most small microwaves are between 600-1200 watts. So, “how many watts does it take to run a microwave?” A 1200-watt microwave will require a minimum of a 2000-watt inverter.

We recommend having an inverter that is at least 25% higher in wattage than the appliance you are trying to run. This is to account for any surge in power that may be required when the appliance is first turned on. For a microwave, you would want an inverter that is at least 2500 watts, to be on the safer side.

Will a 300 Watt Inverter Run a Microwave?

A 300-watt inverter is not powerful enough to run a microwave. Microwaves require a lot of power to operate and typically require at least a 1000-watt inverter for a minimum of 600W microwave.

If you are looking to use a microwave while camping or traveling, you will need to find a campsite with electrical hookups or invest in a more powerful inverter.

Can You Run a Microwave on A Modified Sine Wave Inverter?

Yes, you can run a microwave on a modified sine wave inverter. However, the inverter must have a high enough power rating to support the microwave. Additionally, the modified sine wave may cause the microwave to run less efficiently than it would with a pure sine wave inverter.

If you are running the microwave on a modified sine wave inverter, it is important to keep an eye on it to make sure that it is running properly. If you notice any issues, it is best to switch to a pure sine wave inverter to ensure that your microwave is running as efficiently as possible.

Can I Put a Microwave on A 15 Amp Circuit?

Yes, you can put a microwave on a 15-amp circuit. However, you may need to use a circuit breaker with a higher amperage rating to accommodate the increased power draw of the microwave. Additionally, you should check the microwave’s power rating to ensure that it does not exceed the capacity of the circuit.

How Many Amps Does a Small Microwave Use?

Most small microwaves use between 600 and 1,200 watts of power, which is between 5 and 10 amps, running off a standard 120 volt. The average microwave uses about 700 watts, which is about 6 amps. To find out how many amps your microwave uses, look at the wattage listed on the back or bottom of the microwave.

Microwaves Watts

Input Voltage

Amps Draw

600W 120V 5amps
700W 5.83amps
900W 7.5amps
1,000W 8.3amps
1,200W 10amps


Can You Run a Microwave on Solar Power?

Yes, you can run a microwave on solar power. However, solar power is a renewable resource that can be used to generate electricity. Solar panels convert sunlight into electrical energy that can be used to power appliances like microwaves.

In order to run a microwave on solar power, you would need a solar panel system large enough to generate the amount of electricity needed to power the appliance. Solar power is a clean and renewable source of energy that can be used to power a variety of appliances.


In summary, yes, you can. For reference, while on the go in the (Fruita campground) we use the “POTEK 2000W inverter” with 10% efficiency, running 9.09 amperes (that’s about 1,000 watts microwaves). Running on a standard 110v outlet, this microwave draws 10 amps.
