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, reduces 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.

BESTEK 300W Sine Wave Inverter

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 the best car inverter 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
  • 'Plug-and-play'
  • 18-months warranty


  • Fan is always on when the inverter is switched on
  • May not be easy to service as the fuse is built in
Buy From Amazon

Detailed review: This is a compact, light inverter that produces pure sine waves that will keep running your computers, smartphones and camera chargers on 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, over-load 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 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 much higher priced models.

Samlex Solar PST-300-12 PST Series

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 the two standard AC outlets, but no USB ports.


  • 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
Buy From Amazon

Detailed review: A feature that we really liked in this inverter is that the fan starts and stops based on 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, you then you need 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.

Wagan Elite 400W Pro Pure Sine Inverter

Summary: The Wagan Elite 400W Pro unit is able to handle 400W load up to 800W peak or surge wattage. The inverter comes with 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 favourite 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
Buy From Amazon

Detailed review: The pure since 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 roadtrip and overlanding. For a full picture on features and customer reviews, check the Amazon product page!

AIMS Power 1200 Watt Pure Sine Wave Inverter

Summary: The AIMS Power 1200 Watt Inverter is in another league compared to the previous ones we have looked 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 hookups. 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
Buy From Amazon

Detailed review: Tt is important to note that if you hookup to a 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 mode and usability can be greatly improved by buying the remote switch as well.

Power TechON PS1005 Pure Sine Wave Inverter

Summary: The 1500W continuous and 3000W surge power makes this unit truly capable of running most of the appliances that you can possibly bring on an overlanding trip. 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


  • Fan can switch on with no load at all
Buy From Amazon

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!

Xantrex PROWatt 2000 Inverter

Summary: The Xantrex PROWatt 2000 Inverter name may be misleading, as the continuous power produced by this unit is 1800W, with 3000W surge power. You can install the optional remote on/off switch that comes with an extra feature: when equipped with a remote control, the inverter provides automatic ignition lockout, shutting down the inverter's output when the vehicle's 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


  • Weight
  • No accessories are included
Buy From Amazon

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 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 excellent buy for the money. General theme of the reviews is that the device is very reliable and can handle a whole range of electricals that can potentially use 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.

Samlex America PST-2000-12 PST Series Pure Sine Wave Inverter

Summary: The big brother of the PST-300-12, the Samlex America PST-2000-12 PST comes with all of the qualities the smaller model, but of course with 2000W continuous and 3000W surge power, so naturally no cigarette lighter plug as opposed to the 300W model. While the size and weight is 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
  • Fan is rarely on
  • Very quiet
  • Industrial grade build
  • Two GFCI protected outlets


  • No USB ports
  • No digital display
Buy From Amazon

Detailed review: A feature that we really liked in this inverter is that the fan starts and stops based on 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. Please check further details on the Amazon product page.

Conclusion and Buyer's Advice

We reviewed seven different types from six different brands of pure sine wave inverters. This electronic device matches the needs of people who move around a lot. The pure sine wave inverter allows users to use their laptops, mobile gadgets, small appliances, and other electronic products without any interruption and with quality sine waves that will not damage your electronics in the long run.

We also found out that most consumers who’d like to charge larger electronic devices on the go (and not only use inverters to power tools), choose the pure sine inverters rather than modified models.

Two very good choices from the above list

Before making a purchase, we advise consumers to look at the features, specifications, capabilities, and possible weaknesses of the pure sine wave inverter. If the inverter is not a ‘plug-and-play’ type device, so cables and connections have to be installed please seek professional help to set your inverter up, unless you are a professional yourself.

Once you narrowed down your search to a good quality brand, we think the three main features to consider from an overlanding perspective are: power, number of outlets - should include USB, portability - both weight and size.
