What Will a 200 Watt Power Inverter Run? | Best Use of Limited Power Output

A car power inverter is a device that converts direct current (DC) power from a car battery or other DC sources into alternating current (AC) power, allowing you to run electrical appliances and devices that require AC power. A 200-watt inverter is a popular choice for providing portable AC power in various situations. 

In my articles, I discuss everything related to power inverters, and here I delve into what will a 200-watt inverter run, discuss what it can and cannot do, and explore its pros and cons.

Key Takeaways

  • A 200-watt inverter converts DC power to AC power, allowing you to run electrical appliances and devices that require AC power.
  • A 200-watt inverter can power a range of small electrical devices and appliances with low power requirements, such as cell phones, laptops, game consoles, and small household appliances.

  • Power inverters come in two main types: pure sine wave inverters and modified sine wave inverters. Most 200-watt inverters are typically of the modified sine wave type.

  • It's important to consider the wattage rating and power demand of the devices you want to power to ensure they fall within the inverter's capacity.

  • A 200-watt inverter has limitations and may not be suitable for running high-wattage devices or power-hungry appliances like electric stoves or refrigerators.

  • Using a 200-watt inverter with a car battery may drain the battery if used without the engine running. It is recommended to operate the inverter while the engine is on.

  • Pure sine wave inverters provide a cleaner power output, while modified sine wave inverters may cause issues with sensitive electronic devices.

  • A 200-watt inverter is compact, portable, and relatively affordable compared to higher-wattage models.

  • Consider the pros and cons of a 200-watt inverter before making a purchase decision based on your specific power needs and the devices you intend to run.

What Can a 200 Watt Power Inverter Run?

Inverter used by appliances in home

A 200-watt inverter provides 200 watts of continuous power and can run low-power AC electrical devices including cell phone chargers, game consoles, DVD players, laptop computers, electric toothbrushes, small stereos, fans, lights, and other electrical appliances.

As a power inverter for camping, the 200 watt inverter can run a microwave, coffee maker, or electric stove.

Digital LED display allows instant status of input voltage, output voltage, and output power.

It's important to note that the actual devices a 200-watt inverter can power may vary depending on their wattage rating and power demand.

A 200-watt inverter is suited to running low-power electrical appliances whose combined maximum power draw does not exceed 200 watts and surge power no more than 400 watts.

Some of the battery power is lost as heat during the conversion process and is not available for the connected appliances to use.

Understanding Power Inverters

A power inverter is an electronic device that transforms DC power into AC power.

It enables you to use AC-powered devices and appliances when you don't have access to a traditional power outlet.

Power inverters are commonly used in vehicles, boats, RVs, and during outdoor activities such as camping or road trips.

How do I calculate what size inverter I need?

In order to calculate what size inverter you need, you first need to determine your power demand.

This can be done by adding together the power ratings of all the devices or appliances you want the inverter to supply power to.

Power Inverter Types: Pure Sine Wave vs. Modified Sine Wave

The differences between Modified Sine Wave Inverters vs Pure Sine Wave inverters

Power inverters come in two main types: pure sine wave inverters and modified sine wave inverters.

A pure sine wave inverters produce a smooth and consistent AC power output that closely resembles the power supplied by electrical grids and are ideal for semi-trucks, utility vehicles and to power up other heavy-duty loads and sensitive electronics.

On the other hand, a modified sine wave inverter generates a less refined power output.

Most small inverters, including 200-watt models, are often modified sine wave inverters.

Pros and Cons of a 200 Watt Power Inverter

Here are some key advantages and disadvantages of using a 200-watt inverter:


  • Compact and portable design
  • Affordable compared to higher-wattage inverters
  • Suitable for powering small electronics and low-power appliances
  • Compatible with most cars' cigarette lighter socket or battery terminals
  • Can be used with a solar panel to harness solar power


  • Limited power output for high-wattage devices
  • Not suitable for running large appliances such as electric stoves or refrigerators

Frequently Asked Questions

How many watts can a 200 watt inverter run?

A 200-watt inverter can run devices that have a combined wattage within its capacity. However, it's important to consider the specific power requirements of each device to ensure it doesn't exceed the inverter's capacity.

Do inverters drain the battery when not in use?

No, Inverters don’t drain the battery when not in use, as long as they are not connected to an electrical load.

Can a 200-watt inverter run a laptop?

Yes, a 200-watt inverter can typically power a laptop computer, as long as the laptop's power consumption falls within the inverter's capacity.

How much power can a car inverter supply?

Run phones, computers, or small appliances right from your vehicle. A car power inverter can turn a vehicle's 12-volt direct current power supply into an 120-volt alternating current found in household grids.

How much electricity does a 200W solar panel generate?

A 200W solar panel can generate approximately 400 – 450 kWh of electrical energy every year, depending on the amount of sun exposure it receives and the amount of shade it experiences throughout the day.

Final Words

A 200-watt inverter serves as a versatile and affordable power inverter for powering small electrical devices and appliances on the go. It is ideal for charging cell phones, running laptops, and operating various low-power gadgets.

However, it has limitations when it comes to high-wattage devices and power-hungry appliances. Understanding the capabilities and limitations of a 200-watt inverter will help you make informed decisions about using it effectively and efficiently.

It's important to choose the right car battery and inverter combination. The inverter will need to be compatible with the type of car battery that you are using.
