Buying Guide: Finding the Best Power Inverter for Semi Truck

When looking for a power inverter for your semi truck there’s a number of important factors to consider. 


The amount of output power you require is crucial to ensure you are able to run all the electronics you require at once. If you don’t have enough power you won’t be able to run an appliance or you’ll have to keep powering up different devices at different times. Put simply, it will be incredibly frustrating to get wrong. 

Power output is measured in watts. We recommended having at least between 1500 and 5000 watts for a semi truck. To work out the best option find the wattage rating of all the devices you want to run at the same time. Then add them together to get the total power you require.

For example, if you have a TV at 70 watts, a refrigerator at 100 watts, games console at 150 watts, and heater at 2000 watts. You then add together 70 + 100 + 150 + 2000 = 2320 watts. So you’d need a power inverter with a higher watt output such as 2500+ watts.

Outlets & Connectivity

Take the time to decide the number of electronics you want to connect at the same time and the type of outlet they require.

You’re likely to have a wide selection of appliances and gadgets you’re looking to run, all of which have different requirements.

You’ll find various different options from standard AC sockets, to USB, to fast charging ports. If you plan to run multiple home appliances then 3 or 4 AC outlets would be handy.

Whereas if you want to charge a phone, tablet, and USB light simultaneously then added USB and fast charging is a must. Plus, you might even find wireless charging capabilities on the newest models!


Generally speaking, the higher the power the bigger the inverter. While it can be tempting to pick the most powerful high spec product, this is contingent on space. Work out where you will be mounting the unit in your truck so you know the maximum size of inverter you can fit.

Modified vs Pure Sine Wave

Modified and pure sine wave can be a little hard to understand. 

Simply put, pure sine wave is a smother current flowing to your devices. This means it is better for sensitive devices that need a steady flow of power such as LED TVs, computers, tools, and medical equipment.

Modified sine wave is usually cheaper, drains less battery, and can still run many devices including old TVs, phone charging, laptop charging, mini-fridges, and lighting. Some people are quite happy with this style of inverter but the lower price does come with its drawbacks including more noise/buzzing, less efficiency, and hotter running temperature.


As with any product, there’s a whole host of different features you can find on power inverters these days from Bluetooth control to wireless charging. Added features help to add a better user experience so decide what is important to you. Features you might find include:

  • Fast charging
  • Remote control
  • Bluetooth
  • Digital display
  • LCD screen
  • Wireless charging
  • Carry handle
  • Smart fans


One thing you can’t overlook is safety for both yourself and your electronics. Firstly there is always a fire risk with electricity. Plus you want to ensure your devices are kept safe from damage in case of a fault. All of the products in the list above include essential safety features such as guards against over-voltage, overload, under-voltage, overheating, short circuit protection.

It is also crucial to correctly match the inverter with the battery type. Generally, you will either have a 12 volt or 24 volt battery and you should use the corresponding inverter type. If you try to use a 12V inverter with a 24V battery you will overload your system instantly!

Price & Warranty

So how much should you be paying? Well, decent quality products like the ones reviewed above will cost anywhere between $150 and $600+. This price point very much depends on what you buy. A higher wattage pure sine wave inverter is going to cost you more than $400 while a 1000 watt modified sine wave option could be as little as $150.

You should also take note of the warranty period to ensure you are covered in case of any technical faults. You want at least a 1 year warranty to replace the unit if it fails. The top manufacturers often offer a warranty period of between 2-5 years for your complete peace of mind. A long warranty is also a great sign of quality as it means the company stands by its work and trusts the durability of its products.

Power Inverter vs Portable Generator

During your research, you may have come across other options such as portable generators. In reality, using a portable generator is not going to be very feasible compared to a power inverter.


They are noisy and produce exhaust fumes which are not suitable for use in enclosed spaces like your truck cab! Here’s the difference for you to compare:

  • Inverter: Draws electicity from the vehilce or leisure battery which is ideal for the silent and fume free running of your devices. Plus the batteries recharge from the vehilce engine when driving.
  • Portable Generator: This uses a small combustion engine to create its own electricity from gas or deisel. They are heavy and unpractible for vehicles. You wouldn’t be able to use it inside the truck due to the exhaust fumes and noise.


How big of an inverter can I put in my truck?

This depends on the size of your truck and the space you have available. In our experience, the best size is between 1500 to 5000 watts. Anything more powerful than this will take up to much power and space to fit in the cab. Plus if you are drawing power from the vehicle battery you need to make sure your alternator can cope with drawing large amps. If you want to run 2500+ watt inverters you should consider getting a deep cycle battery to power your appliances via the inverter.

How much does it cost to install an inverter in a truck?

Power inverter setups for trucks can cost anywhere between $150 to $850 depending on the inverter you buy. The higher the power and spec of the inverter the more expensive it will be. When installing the inverter you can do it yourself or hire a vehicle electrician which should take more than an hour to install.

Does an inverter use power if nothing is plugged in?

Yes, a power inverter will use a small trickle of power even when nothing is plugged in. This is because it will be using power for its own features like safety, LED lights, fans, and screen. When turned on, an inverter will use 8-10% of power even when nothing else is plugged in.

Will an inverter drain my semi truck battery?

Yes, a power inverter will drain the battery of a semi truck. If you use your vehicle battery to power your inverter it is important to keep your engine running otherwise you will exhaust the battery very quickly. With no battery power, you will not be able to start your engine!

What does an inverter do in a semi truck?

A power inverter in a semi truck enables you to convert 12V DC power from a battery into 120V AC electricity just like you use at home from the main grid. It allows you to run home appliances in your truck such as refrigerators, heaters, TVs, and much more.

Power Inverter for Semi Truck Summary

So there you have it, everything you could ever want to know in finding the best power inverter for semi trucks. There’s nothing more to say on the subject. Take the time to find the right product for you from the information above and keep on truckin’.
