  • Top 6 Best Power Inverter for Semi Truck Reviews

    1. GoWISE PS1004 3000 Watt Pure Sine Wave Power Inverter

    Coming in at number one on my list of best power inverters for trucks and semi-trucks is the GoWish 3000W power inverter. This power inverter is one of the best-selling on the market and for good reason. It is my personal favorite power inverter to use when I am taking my truck our for a long drive and the power inverter that came most highly recommended by the semi-truck drivers that I know. This 3000 watt power inverter is a pure sine inverter, which is one of the most important factors to consider when buying a power inverter that you will use frequently.

    Pure sine wave power inverters produce consistent and reliable power that will not wane in frequency or wattage, this is what you will need if you want to power complex electrical appliances like new LED televisions. Modified sine wave inverters on the other hand are used to power simple electronics like motors. If you will be using more technical appliances you should almost certainly choose a pure sine wave inverter like the GoWise 3000 watt power inverter.
    One of my favorite features about this power inverter is that it is consistent and reliable. While this is common with power inverters it is always nice to know that the product you buy will perform as expected. I personally have been using the GoWise since late 2017 and my unit has never once failed. Knowing that your power inverter will work day or night will give you peace of mind on the road and it is one of the main reasons why we choose this as our number one power inverter for trucks and semi-trucks.

    Additionally, this power inverter comes equipped with five protection systems, including overload protection, thermal protection, under shelter, overvoltage protection and under voltage protection. Along with the protection systems, the powerful cooling fan on this inverter will ensure that your power inverter will remain cool and safe while in use. Safety features are extremely important, especially for semi-truck power inverters, since they will be used inside the truck. The GoWise power inverter is one of the safest options on the market and you should have zero concern using it as your semi-truck power inverter.

    Finally, size. For many people looking to buy a power inverter, size is not much of an issue as you can really place them anywhere you want, however for a power inverter for a truck or semi-truck size become very important. This model is just under two feet long, nine inches wide, and has a height of four inches. While not the smallest inverter, with the 3000 watts of continuous power and 6000 watt surge power the GoWise power inverter pack a punch for its size. Considering that you have three AC outlets and a USB port it is unlikely that you would need an additional power inverter if you choose this as the power inverter for your truck or semi-truck.

    Overall our team feels as though this is the clear number one choice if you are looking for a new power inverter for your truck or semi-truck. It is relatively small, packs a ton of power, is very safe, and extremely reliable. In my three plus years using the GoWise 3000 watt inverter I have really enjoyed it and have used it to power everything from a mini fridge, to my water pump, to all sorts of phone and laptop chargers. With its 3000 watt continuous power you have the versatility to power large heavy duty appliances or, because of its three AC outlets and USB port, you can opt to power a number of smaller appliances all at once. This really is an excellent power inverter, and we would recommend it to any type of semi-truck driver from a local route driver to a long distance OTR trucker. 


    • Offers high-end service and consistent reliable power 
    • Very durable and will last you years if taken take of properly
    • Comes with a 1-year limited warranty
    • Features multiple protection systems to ensure safety while in use
    • Has great efficiency and operates quietly


    • Slightly larger than some other power inverters on the market


    The device guarantees the best service which is why our team rated it as the number one semi-truck power inverter. It is one of the best-designed products for a semi-truck due to its high end performance and durability, and we would be confident recommending it to any trucker looking for a new power inverter to make their semi-truck more comfortable on the road. 

    2. Giandel 5000W Heavy Duty Modified Sine Wave Power Inverter

    The most high powered inverter one our list today, the Giandel 5000 watt modified sine wave inverter is the number two inverter for trucks and semi-trucks. Coming with 5000 watts of continuous power and 10,000 watts of surge power the Giandel Heavy duty power inverter has enough power to run anything that you might need while on the road.

    Personally, I have not used the Giandel 5000 watt inverter however it comes highly recommended from a OTR trucker that I have known for many years. Although it is a modified sine wave inverter rather than pure sine wave, he said that he would still choose this inverter over most others on the market. Modified sine wave inverters provide more inconsistent power, however they are more than sufficient to power a great number of appliances that you would want in your semi-truck such as a cooling system, microwave or chargers.

    This unit has four AC outlets along with a USB port. Having this many outlets it great as it allows you to utilize all the power that this heavy duty power inverter has to offer. While some other inverters may provide high wattage, if they do not have a sufficient number of outlets the power is of no use unless it is being used by one or two devices. With the Giandel 5000, you can spread out your 5000 watts of continuous power to four different appliances and a USB allowing you to power lots of different things at the same time.

    Safety is one of our biggest concerns here at Powermurt and was something that I made sure to emphasize when talking to my trucking friend about this power inverter. Modified sine wave inverters are known to be less safe than more modern pure sine wave inverters and I wanted to make absolutely sure that we were not recommending something that might not be safe for our users. That is simply not the case with the Giandel power inverter. It comes with a number of excellent safety features including over and under voltage protection, fuse polarity protection, overheat shut off capabilities, and an auto restart function that will help you get your power back quickly if something were to happen.

    Overall this is a great option for an OTR trucker and provide more than sufficient power to run almost any appliance you might need. Additionally, with its extremely high surge power it has the capability to start up appliances such as heavy duty water pumps which might not be possible with some other, lower wattage power inverters. 


    • One of the highest power inverters you can find at a reasonable price
    • Relatively small, can fit in most places without much difficulty
    • Huge surge power allows you to run almost any appliance
    • Very safe, no need to worry about running inside your semi-truck


    • Modified sine wave inverter, NOT pure sine wave, cannot be used for sensitive electronics like high end LED televisions


    Recommended to our team by one of my longtime friends, someone who has been trucking for over 10 years, you simply won’t be disappointed if you decided to buy the Giandel 5000 watt modified sine wave power inverter. From its high power, to its reliability, to the company’s excellent customer support there is almost nothing to be hesitant about regarding this power inverter for trucks and semi-trucks. 

    3. Samlex PST-2000 Watt Pure Sine Wave Inverter

    Coming in at the number three spot on our list of best power inverters for trucks and semi-trucks is the Samlex 2000 watt pure sine wave inverter. The lowest powered inverter on our list so far, the Samlex makes up for its lack of power with its extremely efficient, and reliable design. This power inverter is, in my professional opinion, more for the local or regional trucker who might be spending 1-2 days on the road rather than the OTR trucker who might be away from home for weeks at a time. With its relatively lower power the Samlex is designed to power slightly smaller appliances, however with 4000 watt surge power, it is capable of running some more heavy duty electrical devices. I have even used it for water heaters though I don’t recommend that unless you really know what you are doing. 

    When I think about the Samlex 2000 watt power inverter what stands out to me is its versatility. As a pure sine wave inverter it will supply power sufficient to run any type of device that you have. Additionally, this unit is relatively small, and can be stored almost anywhere in your semi-truck. While you might not think that size is a big issue let me be the first to say that saving space wherever and however you can is of upmost importance. Unless you’re going to be on the road for weeks at a time, keeping your truck as spacious as possible is a great way to make your time on trucking more enjoyable. Having an inverter that is just under two feet long but still capable of running everything you need from it is a big plus and one of the reasons that the Samlex 2000 watt inverter made it to number three on my list.

    In addition to its small stature and formidable power output, actually operating the Samlex 2000 is very enjoyable. Coming fully equipped with standard safety features, this power inverter is FCC approved, which is an absolute must have in my opinion. The Samlex also have a fully temperature controlled fan which works silently to cool your inverter, increase in lifespan, improve its efficiency. Most companies will say that your inverters fan works silently but after using it for a while it will start to become very loud. This is not the case for the Samlex, and after using it for over 4 years, my friend is still talking about how quiet this model is for a power inverter.

    Overall, from everything that I have learned from my research on the Samlex 2000 watt inverter, including my own independent research and the information that I have gathered from people who have used the Samlex for multiple years, there is almost no downside to this power inverter. If it were available in a 3000 watt version it would be our clear number one inverter, however some people need more than 2000 watts which is why I decided to lower it to our number three spot. This power inverter is consistent, reliable, and safe, all the things that we look for when choosing new inverters to recommend. For the local or regional semi-truck driver I strongly feel that this would be your best option and even for an OTR trucker it would be an excellent choice.


    • Excellent power output that is consistent and reliable
    • Compact enough to fit almost anywhere in your semi-truck
    • Safe to use day and night without turning it off
    • Very quiet fan that keeps your power inverter cool and functional without causing a disruption


    • Only 2000 watts, enough for a majority of appliances but there might be a time where you need a bit more power if you plan on bringing large appliances with you in your semi-truck


    We would recommend the Samlex 2000 watt pure sine wave power inverter to any and all local or regional semi-truck drivers, and virtually all OTR semi-truck drivers. One of the most high performing power inverters on the market this unit will not let you down no matter how much you use it.

    4. KRIËGER 1100 Watt 12V Power Inverter

    If a heavy-duty power inverter is in your thoughts, the Krieger 1100 Watt power inverter very well could be the right choice for you. It is powerful enough to power handheld power tools, gaming consoles, televisions, home electronics and small gadgets in your truck and with it, you'll never be disappointed with the power. And if you need more power, this unit has different versions which go up to 4000 Watts!

    Throughout my years I have traveled a great number of miles in my RV and pickup truck and a small power inverter like the Krieger 1100 watt inverter is something that I always carry with me. In the past my small inverters have either given off inconsistent power, or been manufactured poorly. The Krieger 1100 does neither of these things. I have had this inverter for the past two and a half years now, using it consistently 2-3 times per week and it works as though I bought it yesterday.

    Although this is a modified sine wave inverter, it is still sufficient to power lots of different things, for more complex electronics however, a pure sine wave inverter is definitely the right choice. This unit comes with an advanced LCD that shows the input voltage and this, along with the battery level, makes it very simple to check the output wattage in real-time. Additionally, thanks to its thermal fan, you can operate the Krieger 1100 for hours without any problem whatso ever.

    In addition to this, Krieger 1100W looks fantastic with a sleek look of black and yellow which complement each other to perfection. Obviously the look of your new power inverter is not the most important quality, but it is nice to know that the product you buy will look somewhat stylish. Overall this is a high quality power inverter if not the most exciting piece of technology out there. For its very inexpensive price tag you will be getting something that does exactly what you expect, when you expect it, and that is a quality that cannot be overlooked. The complete package comes with all the installation wires and kit equipment, which means easier set up for you, and the installation process is fast and quick. If you are looking for a new power inverter for some heavy duty power tools or equipment, or simply looking for a new power inverter to complement your current collection, you will not go wrong with the Krieger 1100 watt power inverter.


    • Super light and compact, can be stored almost anywhere
    • Comes with LCD display which shows battery, watt, and volt level
    • Almost silent while in operation
    • Can provide power to multiple devices with two AC outlets and


    • 1100w isn't that powerful to power more heavy duty equipment
    • Modified not pure sine wave


    Depending on your trucking needs the KRIËGER 1100 may very well might be the perfect power inverter for you. As more of a niche inverter, I would recommend this power inverter to someone who has a more hands on job and needs to use power tools often. While this inverter can power some helpful appliances in your semi-truck like a mini fridge, because it is a modified sine wave inverter, we cannot in good faith recommend it as your sole inverter. It would be better served as a complementary inverter to a more heavy duty, two or three thousand watt pure sine wave inverter.  However, it can serve you hours without issues or any disruptions and its near silent operation  makes it very user-friendly in almost any environment. As a complementary inverter or a main inverter for someone who uses power tools often, the Krieger 1100 watt modified sine wave power inverter is an excellent choice.

    How to choose Best Power Inverter for Semi Truck

    Every time you're making a purchase, it's important to note a few things into consideration. A right choice ensures you select the best model for your semi-truck.

    If you're a beginner, this can prove to be complicated. First, decide your needs and requirements. Our comprehensive guide checks out a lot of things you need to consider.


    Most people have a common belief that large power inverters are the best. Fortunately, it's not always right. You'll notice that the size of a unit has less to do with power delivery and capability. The size of your product should fit your store and place entirely. Consider measuring it if you got a place to mount.

    Modified wave or sine wave

    Power inverters for either semi-trucks or RVs are available in the market in two variants. They are either a sine wave or modified wave technology. Both of the techniques mentioned above come with their uses and significance.

    If you're planning to equip your truck with power-sensitive tools such as drilling machines, it's advisable to stick with a sine wave inverter. The technology delivers power without obstacles and any fluctuations.


    Knowing connectivity is essential. It helps you to connect and assemble your device correctly. Find out the type of outlets that your power inverter has. In most cases, low powered inverters have few USB ports and AC outlets.

    Contrary, the high powered ones come with at least three outlets and several USB ports. If you carry more devices around you, you should pick the model that fulfils the requirements.


    Safety! Safety! It comes in vain if your choice doesn't offer enough protection to you and your devices. Because inverters deal with electricity, high-quality safety features matter.

    This will save the user from emergency and unnecessary electrical issues. The current electric problems include overvoltage, overheating and overloads. That way, choose a unit that has a thermal fan.


    Prices of different power inverters may depend on several things like sine wave type, power and more. It's always good to go for highly-priced products, but the less costly ones are also better. The point is that you should refrain yourself from overspending. Instead, remain with your budget.

    Final Verdict

    With our best power inverter for semi-truck review, we hope that now have the upper hand when making a decision. While best products bring happiness and satisfaction, wrong power inverters cause trouble to your devices.
