Quick Answer – Best Pure Sine Wave Inverter:
As you could see in our Inverter Buying Guide, we think that if you have several electronic devices that you take with you on a trip, it makes sense to invest into a Pure Sine Wave Inverter, rather than a modified sine wave one.
This type of inverter, by producing pure sine waves rather than modified sine, makes use of advanced technology in protecting very delicate electronic items.
With so many options on the market, it is very hard to decide which one to choose, so hopefully our best Pure Sine Wave Inverter Reviews will help you with that.
Modified sine wave inverters are more suitable for basic electronics and appliances like power tools and battery chargers.
There are several benefits to the pure sine wave inverters as opposed to the modified sine wave inverters. They produce less irritating noise, reduce unpredicted power shutdown and possibilities of errors, machine motors function at the correct speed without the risk of overheating, just to name a few from our inverter guide.
Therefore, in this article, we are going to review some of the best pure sine wave inverters from the most popular inverter brands in the range of 300 to 2000 Watts.
Best Pure Sine Wave Inverters
Best Pure Sine Wave Inverters
Summary: This Pure Sine Wave Inverter puts out 300 watts of nonstop pure sine wave power, with 700 watts of surge power. This BESTEK product is a small and handy gadget designed for easy handling and portability.
It is equipped with two regular AC outlets and two smart charging USB ports with 2.4 amps per port and 4.8 amps in total. These are smart charging ports, which means it will automatically detect your devices once they are plugged in and start charging them without having to turn the inverter on.
This is the first one in our list of reviews, but since the unit is very compact, has got two AC outlets along with a USB port and it is a ‘plug-and-play’ device, we may already say that this can be one of the best car inverters on the market.
That is if you are not planning to run many devices in your big expedition truck. In that case, you will need to look for an inverter with a bit more power.
- 2 USB ports
- Compact size and weight
- 12V cigarette lighter plug
- 18-months warranty
- The fan is always on when the inverter is switched on
- It May not be easy to service as the fuse is built-in
Detailed review: This is a compact, light inverter that produces pure sine waves that will keep running your computers, smartphones, and camera chargers in the long run.
A satisfied customer said he was very surprised to see that the output on his testing device was a very clean sine wave. He was not expecting this, considering the price. Naturally, he gave it 5 stars on Amazon.
With its 6.34” x 3.84” x 2.28” dimensions and weight of only 1.37 lbs, it is a great choice for people who are on the road a lot and only need a compact inverter, but not using high wattage items such as a hairdryer or electric stove. Those usually require much more than 300W.
It has 2 regular AC outlets and 2 USB ports. There is an LED status light that either indicates that the inverter is on and working fine (Green light) or that the product has detected some issues (overheating, overload, etc), in which case it turns red and stops producing the 110V current.
We find BESTEK’s design as compact and convenient without unnecessary wires and assembly. One customer said he was not impressed and the product is not worth the cost but this was only one negative comment compared to outstanding reviews.
With an 18-months warranty, we find this product a good and cost-effective purchase. As long as you don’t need more than 300W with 700W surge power, then it has all the features (including USB ports) that you would expect to find in many higher-priced models.

Summary: With its 9.69” x 5.76” x 2.58” dimensions this Samlex Solar PST-300-12 Series Pure Sine Wave Inverter is slightly larger than the previous model we mentioned, however, that comes with a more sturdy design and GFCI protected outlets.
Although it comes with a cigarette lighter plug, it is not hard-wired, which means you can use the wire set with battery clamps instead to power the inverter directly from a battery.
The wire set is also included in the box and can be connected through the tubular-type screw-down terminals. However, you will need larger cables than the included ones if you want to use the inverter to its full 300W potential, rather than to the 150W limit through the manufacturer’s cables.
The device has a surge power of 500W and it is equipped with two standard AC outlets, but no USB ports.
- The fan is rarely on
- Comes with both cigarette lighter plug and battery cables
- Very quiet
- Optional remote control for the 600W model
- Very reliable
- Limited to 150W with cables provided
- No USB ports
Detailed review: A feature that we really liked in this inverter is that the fan starts and stops based on the measured temperature, therefore, for some time it can operate completely silently. For smaller loads, the fan does not need to turn on at all, even for a longer period.
Most buyers said the fans rarely come on and they are very quiet even when they do. The sleek metal unit weighs 3.46 lbs.
If you decide to run this inverter at the full load capacity of 300 watts, then you need to purchase larger cables according to the manufacturer’s recommendations in the user manual.
If you are not a professional, we would advise you to seek professional help in order to wire the inverter this way, as incorrectly installing wires can be very dangerous. One customer complained that the need to install larger cables may not be obvious when purchasing the product.
Samlex is a great brand in the inverter market and if someone is happy with the 12-PST series, they can choose from a range of 300W, 600W, 1500W, and 2000W models and for the 600W item even opt for the RC-15A PST remote control.
Summary: The Wagan Elite 400W Pro unit is able to handle 400W load up to 800W peak or surge wattage. The inverter comes with a cigarette lighter plug as well as with cables that use alligator clamps.
The cigarette lighter cable is limited to 150W load so you could make better use of your device by installing the other cord, which can handle the full 400W capacity.
The brushed aluminum case looks durable and on the front panel, you can find a 2.1A USB port and two grounded AC outlets. One of our favorite features is the low battery alarm and an automatic low battery shutdown feature.
This will notify you when your battery is getting low (10.5V ± 0.5V) and will shut down the inverter to protect the battery from over-discharging and possibly damaging it (9.5V ± 0.5V)
- USB port
- Low battery alarm and shut down
- Replaceable standard fuses
- Comes with both cigarette lighter plug and battery cables
- Limited to 150W with cigarette lighter plug
- Frequent false low battery alarm
Detailed review: The pure sine wave this device produces made a customer very happy when he needed to use a heating blanket as that product would not have worked with modified sine.
While several customers praised the quietness, reliability, and great size, we have to mention that some buyers complained about the low battery alarm going off unnecessarily and for one customer the USB port did not produce the claimed attributes.
It may not be obvious from the outside but the fuses are replaceable. The unit has to be disassembled, but the standard 25A automotive blade fuses can easily be replaced.
This pure sine wave inverter is still a compact unit with its 6.0”x8.0”x2.0” dimensions and weight of 2.0 lbs so it can be a great choice for a road trip and overlanding. For a full picture of features and customer reviews, check the Amazon product page!
Summary: The AIMS Power 1200 Watt Inverter is in another league compared to the previous ones we have looked at in terms of power output. It maintains 1,200 watts of uninterrupted pure sine power. It is equipped with an integrated 10 Amp transfer switch for pass-through capabilities when shore power is connected.
Ideal if you decide to stay in campsites with electrical hook-ups. The electric current will be continuous, however, the AC input and output need hardwire connections, i.e. there are no standard AC sockets.
We would not consider this as a compact unit at 15.25’’ x 9.4’’ x 3.8’’ and 10.2 lbs.
- Affordable price for the power
- AC power pass-through capability – with built-in transfer switch
- Optional remote switch
- Powerful enough to run even a microwave
- Quality build
- The unit has to be on to pass through AC shore power
- Draws battery power even on shore power
Detailed review: It is important to note that if you hook up to shore power the AC power will be passed through but only if a 12 Volt DC power is present and the inverter is turned on. Therefore you need to have a battery connected.
An interesting review specifies the product’s robustness and practical functions of the transfer switch and another customer remarked that performance was outstanding and the price is really affordable.
One Amazon customer admitted returning the first unit due to a bad fan but the replacement item has been functioning seamlessly since then. The fan is always on, but since it is only producing a “soft hum”, it does not seem to be an issue.
While having no standard AC outlets, nor USB ports might put some people off this product, but customers who tend to buy this inverter appear to be preferring this feature as setting it up neatly in your truck would give you a powerful and reliable pure sine wave inverter with the above-mentioned pass-through functionality as well.
We believe consumers get value for their money in choosing this model and usability can be greatly improved by buying the remote switch as well.
The pure sine-producing unit is ideal not only for overlanding rigs, but also for motorhomes, boats, or as a backup for power failure at your home.
The power comes with an expected larger size of 15.8’’ x 9.3’’ x 4’’ and 9.9 lbs weight. It is fitted with four outlets in total: three AC sockets and a USB port.
- 3 standard AC outputs
- USB port
- 5 protections systems
- The fan can switch on with no load at all
Detailed review: A contented user simply said the Power TechON PS1005 works perfectly. He has been using the product for five months to power the family’s refrigerator and washing machine.
So far, they have not encountered any issues yet. A couple of customers prefer this brand because it is relatively quiet. However, they advised to warm up the unit for several seconds before plugging in to avoid damage.
Customers often use it to power their space heater while out camping and according to their testimonials, there have been no issues, the inverter can handle it easily. Of course, you need to make sure your heater would not exceed the 1500W limit.
To sum up, the PS1005 model is a great unit in the 1500W/3000W range. Check out more pictures on the Amazon product gallery!
Summary: The Xantrex PROWatt 2000 Inverter name may be misleading, as the continuous power produced by this unit is 1800W, with 3000W surge power.
So, you should not put it in the list of 2000 watt inverters. You can install the optional remote on/off switch that comes with an extra feature: when equipped with remote control, the inverter provides automatic ignition lockout, shutting down the inverter’s output when the vehicle ignition is not engaged.
You could say the two GFCI protected AC outlets and the USB port are standards for an inverter in this category, however, the digital display for DC volts and output power definitely not usual.
- Built-in digital display for DC volts and output power
- USB port
- Two GFCI protected AC sockets
- Optional remote switch with ignition lockout
- Optional transfer switch for shore power usage
- Fan only comes on around 1500W load
- No accessories are included
Detailed review: This quality inverter can be complemented by the transfer switch to use shore power when available and the remote on/off switch. You have to purchase them separately, but installing all of them would give you a nice setup.
If you are looking for a pure sine wave inverter in the 1500W-2000W continuous power range, this Xantrex unit is probably one of the best ones on the market.
A happy customer added a review on Amazon saying it is an excellent buy for the money.
The general theme of the reviews is that the device is very reliable and can handle a whole range of electricals that can potentially be used on an overlanding trip and more.
We were focusing on the 1800W model that has a size of 13.8” x 11.8” x 3.9” inch and 10.6 pounds weight. However, if you are planning to purchase an inverter for your overlanding truck, you might want to know that the PROwatt SW series are available in 600W and 1000W models as well. Our inverter buying guide should help you decide what power range to chose.
Considering its features and customer experiences, the Xantrex PROWatt 2000 inverter is a highly recommended product.
Summary: The big brother of the PST-300-12, the Samlex America PST-2000-12 PST comes with all of the qualities of the smaller model, but of course with 2000W continuous power and 3000W surge power, so naturally no cigarette lighter plug as opposed to the 300W model.
While the size and weight are considerable, compared to cheaper models, this gave some buyers their first impression of great build quality and reliability. It comes with no USB port but with two GFCI protected outlets.
- Very reliable
- The fan is rarely on
- Very quiet
- Industrial grade build
- Two GFCI protected outlets
- No USB ports
- No digital display
Detailed review: A feature that we really liked in this inverter is that the fan starts and stops based on the measured temperature, therefore, for some time it can operate completely silently.
For smaller loads, the fan does not need to turn on at all, even for a longer period. Most buyers said the fans rarely come on and they are very quiet even when they do. The sleek metal unit weighs 17.6 lbs with dimensions of 20.7’’ x 12’’ x 6.4’’.
As we also mentioned it for the 300W model above, Samlex is a great brand in the inverter market. A content customer who gave the unit 5 stars in his review said he tried a few other inverters before and paying for quality brands is really worth considering.
He said this Samlex device is a top-of-the-line inverter. This could be one of the best inverters for RVs. Please check further details on theAmazon product page.

You have to make sure that you are getting an inverter that can power up all the devices you are going to use in your car without any issues. Also, you should not use one that has a very high power output rating compared to what you are going to need.
That way you will waste both the power and money. In addition, you should also make sure the size of the inverter will fit in your car.
Build Quality and Warranty
You don’t want to buy a Pure Sine Wave inverter from time to time. You will want long term service from the device. As a result, you will have to go with the best Pure Sine Wave inverter in the market that comes with robust build quality.
In addition, you will also want to get one from a brand that offers a long term reliable warranty policy. So even if there are any issues with the unit, you will be able to get it fixed with no additional cost.
The best Pure Sine Wave inverters will come with a 90 to 95% efficiency rating. Whereas the low-quality Modified Sine Wave inverters are rated at 80 to 85%. Thus, the higher the efficiency rating the better.
Every Pure Sine Wave inverter will come with a number of power outputs. The exact number will vary from model to model. If you need multiple devices to the power-up or charge at the same time, you can go with inverters that come with multiple power outlets.
On the opposite, one AC power outlet is also sufficient if you have less number of devices to charge. Remember, inverters with more power outlets will be pricier and heavier.
The best Pure Sine Wave inverters will also come with USB ports. That way you will be able to charge your smartphones or USB enabled devices easily. If that is your requirements choose one that comes with multiple USB ports.
This is a feature that is not very common. Rather, it is only available on some of the best Pure Sine Wave inverters.
In the case of most inverters, the display will show the input voltage, output power, and some other important information. That way, with the help of the display, you will be able to know the condition of the power inverter.
The best Pure Sine Wave power inverter will be equipped with various safety protection features.
For instance, it should come with over/under voltage protection, short circuit protection, overheat protection, polarity reverse protection, and more. It should also feature an auto-restart and soft-start function.
Pure Sine Wave vs. Modified Sine Wave Inverters
There are a few key differences between Pure Sine Wave and Modified Sine Wave inverters. First off, they have a different mechanism of producing power. Pure sine wave inverters are designed to produce a clean or perfect form of electricity.
On the other hand, modified sine wave inverters cannot do that. As a result, using sensitive electrical products with a modified sine wave inverter is not advisable. Because the efficiency of this type inverters are significantly reduced in the case of some devices.
So it is clear that if you have delicate electrical devices like computers, laptops, washing machines, printers, smartphones, tablets, speakers, etc., a Pure Sine Wave inverter would be the best option compared to the Modified Sine Wave inverter.
However, when it comes to the price, Modified Sine Wave inverters are cheaper than Pure Sine Wave inverters.
What Size Pure Sine Wave Inverter Do I Need?
The power that an inverter output is measured in watt. Also, you will find that there are 2 parameters when it comes to inverter power output that is continuous power and peak or surge power output.
Now the surge power output refers to the highest power that the inverter can output for a moment. This will come in handy for some particular devices.
For instance, there are various electrical devices that need a high amount of power while they startup for a few seconds to minutes. This is known as the surge or peak power required by the appliance.
After the initial phase, the device will not require the peak power output and will run with the continuous power output requirement. In some cases, the surge power output can be as much as twice the continuous power required.
Now the best way to know what size power inverter you will need is to calculate the total power output (both continuous and surge output) you will need. Here we are talking about all the devices you will power up at the same time.
For that, you should check what is the peak and continuous power input requirement on the label of the devices you are going to use and add them together.
Now you should also keep in mind how many devices you are going to power up using the inverter at the same time. Depending on that the power requirement will increase and decrease. In that case, you can also use a low power inverter and power up the appliances one by one to keep the cost low.
In short, you will need to know the power input rating for all the devices (both surge and continuous power) you are going to power up with the inverter to determine the size or power rating of the inverter you are going to purchase.
How To Install And Use The Best Pure Sine Wave Inverter?
Every best Pure Sine Wave Power inverter would come with an instruction manual. Where you will find all the necessary instructions for installing and using the device to its best capability.
So we would suggest you follow the instructions carefully. However, here are a few installation and safety tips, for your convenience.
Avoid exposing the inverter to moisture or rain
Avoid placing the inverter in derelict sunlight
Try to install the inverter vertically or horizontally on a stable flat surface
It is better not to install the inverter in the engine compartment as there will be excessive heat
Always, keep several inches clearance around the inverter
Avoid using the inverter near flammable materials
Do You Really Need A Pure Sine Wave Inverter?
The answer to this question actually depends on the users. For instance, if you need to power up delicate electrical components in your car, you will need a Pure Sine Wave inverter.
Because delicate electrical components like speakers, smartphones, laptops, TV, etc. require pure Sine Wave inverters to run efficiently.
Also, the lifespan of those appliances will increase if you use them with a Pure Sine Wave inverter. Plus, using a Modified Sine Wave inverter would produce high noise from the appliances.
So, if you prefer to have a great journey with all types of electrical appliances on your vehicle, you will need a Pure Sine Wave inverter. But if you don’t need that as well as you want to save some money, you can go with Modified Sine Wave inverters.
What Is The Best Pure Sine Wave Inverter?
Pure Sine Wave inverters come from various brands. Also, they differ in the input and output power rating and features they offer. So, it is very hard to pick only one inverter as the best Pure Sine Wave inverter.
It will be up to the buyers to choose the best Pure Sine Wave inverter according to their preferences and requirements.
When choosing the best Pure Sine Wave, you should keep a few pointers in mind that we have described above like good build quality, reliable power output rating, great warranty policy, multiple power outlets, and more.
