If you’re short on time, here’s a quick answer to your question: You’ll need an inverter that provides at least 1800-2000 watts of continuous power to safely run a 1500 watt portable heater.
In this comprehensive guide, we’ll cover everything you need to know about powering a 1500 watt portable heater. We’ll discuss how to calculate your power needs, what size inverter you need, key factors to consider, recommendations for top inverter models, safety tips, and much more.
Calculating Your Power Needs
Total Wattage Required
When determining the size of an inverter needed to run a 1500 watt heater, it is important to consider the total wattage required. This includes not only the wattage of the heater itself, but also any additional devices that will be connected to the inverter.
For example, if you plan on using the heater while also charging your phone and running a small fan, you would need to factor in the wattage of these devices as well.
One way to calculate the total wattage required is by checking the wattage ratings on each device and adding them together. Alternatively, you could use a power meter to measure the actual wattage being used by each device simultaneously.
Surge Wattage
Another important factor to consider is the surge wattage of the heater. Surge wattage refers to the temporary increase in power consumption that occurs when a device is turned on or starts up. This surge is typically higher than the continuous wattage, which is the amount of power needed to keep the device running.
It is recommended to choose an inverter with a surge wattage rating that is higher than the maximum surge wattage of the heater. This ensures that the inverter can handle the initial power spike without overloading or tripping the circuit.
Continuous Wattage
The continuous wattage of the heater is the amount of power it requires to operate once it has started up. In the case of a 1500 watt heater, the continuous wattage would also be 1500 watts. When selecting an inverter, it is important to choose one that can handle the continuous wattage of the heater.
Keep in mind that some devices may have a higher surge wattage than their continuous wattage. In such cases, it is crucial to ensure that the inverter can handle both the surge and continuous wattage of the heater.
Other Devices
In addition to the heater, it is important to consider any other devices that will be connected to the inverter. This could include items such as lights, electronics, or appliances. Each device will have its own wattage rating, which should be factored into the overall power needs.
It is important to note that different devices may have different power requirements, and it is essential to choose an inverter that can handle the combined wattage of all devices. Failure to do so could result in an overloaded inverter or a blown fuse.

What Size Inverter You Need
When it comes to running a 1500 watt heater, you’ll need to consider the size of the inverter you’ll need. An inverter is a device that converts DC power from a battery into AC power, which is what most household appliances run on.
Here are the key factors to consider when choosing the right size inverter for your heater:
1800-2000 Watts Continuous
The first thing to consider is the continuous power rating of the inverter. Since a 1500 watt heater requires a substantial amount of power to operate, you’ll need an inverter that can handle at least this amount of power continuously.
It’s generally recommended to choose an inverter with a continuous power rating of 1800-2000 watts to ensure it can handle the load of the heater without any issues.
Pure vs Modified Sine Wave
Another important consideration is the type of waveform the inverter produces. Inverters can either produce a pure sine wave or a modified sine wave. A pure sine wave inverter produces a waveform that is similar to the power supplied by the utility grid, making it compatible with all types of appliances, including sensitive electronics.
On the other hand, a modified sine wave inverter produces a waveform that is a rough approximation of a pure sine wave. While it can still power most appliances, some devices, especially those with sensitive electronics, may not function optimally or may even be damaged.
Therefore, it’s recommended to choose a pure sine wave inverter to ensure compatibility and protect your devices.
Getting an Inverter with Surge Capacity
Lastly, it’s important to consider the surge capacity of the inverter. When a heater first starts up, it requires a surge of power to get it going. This surge can be significantly higher than the continuous power rating of the heater.
To accommodate this surge, it’s advisable to choose an inverter with a surge capacity that can handle the initial power spike. This will ensure that the inverter can handle the start-up requirements of the heater without any issues.
When choosing the right size inverter for your 1500 watt heater, it’s important to consider the continuous power rating, the type of waveform, and the surge capacity. By selecting an inverter that meets these requirements, you can ensure that your heater operates smoothly and efficiently.
Key Factors to Consider
Output Waveform
One of the key factors to consider when choosing the right size inverter for a 1500 watt heater is the output waveform. Inverters can produce either a pure sine wave or a modified sine wave. A pure sine wave inverter provides a smooth and clean power output, similar to the electricity you get from the grid.
On the other hand, a modified sine wave inverter produces a more square-like waveform, which can cause issues with some sensitive electronic devices. It is recommended to use a pure sine wave inverter for running a 1500 watt heater to ensure proper and efficient operation.
Number of Outlets
The number of outlets on the inverter is another important factor to consider. A 1500 watt heater typically requires a dedicated circuit, so having multiple outlets on the inverter may not be necessary.
However, if you plan to run other devices simultaneously, such as a laptop or a phone charger, having multiple outlets can be convenient. Consider your power needs and the devices you plan to run when determining the number of outlets required on the inverter.
Safety Features
Safety should always be a top priority when choosing an inverter. Look for safety features such as overload protection, short circuit protection, and over-temperature protection. These features can help prevent damage to the inverter and connected devices in case of power fluctuations or other electrical issues.
Additionally, some inverters may have built-in surge protection to protect against power surges. Prioritizing safety features can provide peace of mind and protect your investment.
Portability
Consider the portability of the inverter if you plan to use it in different locations or during outdoor activities. Look for compact and lightweight models that are easy to carry and transport. Some inverters may also come with built-in handles or carrying cases for added convenience.
Portable inverters are great for camping trips, road trips, or any situation where you need power on the go.
Additional Features
Lastly, consider any additional features that may be beneficial to your specific needs. Some inverters may have built-in USB ports for charging small electronic devices, such as smartphones and tablets. Others may have LCD displays to provide information about voltage, wattage, and battery status.
