In this buying guide, you’ll find all this information along with the 10 best inverters that are well-known nowadays.

What is RV Power Inverter

An RV inverter is also called a ‘power inverter’ for a recreational vehicle. RV inverters are generally power converters with some extra power storage capacity. They also have plugs that allow you to use them as a charger. This is an indispensable tool for running any kind of domestic appliance at home, caravan, or even in camping.

Like, they can charge your smartphone or provide extra power that is stored in their own battery. Some inverter chargers can be used as both converter and inverter by only transferring the switches, fuses, and other electric safety elements.

Types of RV Inverters

There are different types of RV inverters available in the market. The most common of them are-

Pure Sine Wave Inverter

A pure sine inverter creates a cleaner, smoother power supply for your RV. It helps you to run all of your smart devices like- smartphones, laptops, and even big-screen TV. though it is a little bit expensive but worth it if you want to run too many devices with it.

Modified Sine Inverter

Modified sine inverters don’t have any extra components to give you a smooth and clean power supply. So they are cheaper than pure sine. They are perfect for running any basic devices like- blenders, pumps, drills, and air conditioners. But you can not expect it to run all of your devices like the pure one.

Square Wave

These inverters are the most financially conscious inverters available in a wide range. They are similarly fundamentally less successful in using RV.

This kind of inverter can drive straightforward things without a problem. For instance, devices with all-inclusive engines function admirably when provided power from the square wave inverter.

However, most RVs and their equipment require a more mind-boggling power supply than a square wave inverter. This is why you do not see many square wave inverters promoted for use in an RV.

Benefits of Using an Rv Power Inverter

An RV power inverter allows you to convert the DC power stored in your RV’s batteries into AC power, which is what most household appliances and electronics use. This means you can use your standard appliances and devices while on the road or in places where there is no access to an electrical outlet. Some benefits of using an RV power inverter include:

  • Convenience: you can use your normal appliances and devices without having to purchase special versions for use in an RV.
  • Flexibility: you can use your RV in more places, such as boondocking or dry camping, without having to rely on a generator or external power source.
  • Energy efficiency: an inverter can be more efficient than using a generator, especially for smaller loads or when using appliances that have sensitive electronic components.
  • Safety: using an inverter eliminates the need for extension cords and power strips, which can reduce the risk of electrical fires and other hazards.

It’s important to note that you will need to have enough battery power to support the usage of your appliances, and that usage of certain devices will drain your batteries much faster than others. Also, it’s important to check the compatibility of your devices with the power output of the inverter you are using.

How to Choose the Right One

This is the most important question you need to find the answer to before buying an RV inverter.

In this buying guide, I’ve discussed some features that make an RV power inverter the best one. If you are looking to buy a new one, can go through it.


While buying, first you need to check whether the battery power is sufficient or not. Make sure that the batteries of the inverter have adequate power to operate it with your desired devices.

To have an idea about the power consumption, get the total power consumption and then convert it into watts. Now divide the figure by ten.


The next thing you should check is the size of the inverter. The size of the inverter doesn’t refer to its physical size of it, it means the output of the device in the form of watts.

So check how much watt or power is needed to run your devices and get one with 15% more so that you can avoid any unwanted situation.

Overload Protection

Another thing you should check is that the inverter you’re going to buy has the facility of overload protection. This feature will help the inverter to shut down automatically in case of overload.

Waveform Output

You’ll find two options to choose from for waveform output- pure and modified sine.

Modified sine is more affordable than pure one and with it, you’ll be able to run most of your appliances. On the contrary, a pure sine wave can generate cleaner output through the main supply and you can run all of your appliances.


Before buying, make sure that it should not increase energy consumption too much and also doesn’t influence energy loss.

Operating Period

The operating period is the length of time of operation of an inverter. It mostly depends on the capacity of the inverter’s battery and is measured in AMP/ hour. So check that the inverter you’ll buy doesn’t run the battery flat immediately after the input voltage goes below. This type of inverter comes with the feature of sending an alarm in case of battery failure.

  • Weight: 8.8 pounds;
  • Outlets: 3 AC outlets and 2.1A USB;
  • Model no: IVUFA2000. 

To meet the basic needs of an off-grid power option during emergencies, we don’t need fancy high-capacity inverters. In those situations, a low-capacity inverter is easier to use and more convenient to charge with just a 12v DC battery. Ampeak inverter has only 2000 watt continuous capacity and can take up to 4000 watts. But it merely resists 3000 watts without notifying the overload alarm. However, that capacity should suffice for a small refrigerator, blender, vacuum, and other machines. Don’t use it to charge your phone unless you wish to fry it up.

This is one of the lowest-priced inverters on our list. It is not only usable for RV trucks but also useful for outdoor parties, camping, basement, and many other uses. Though it doesn’t cost much, the device is protected using various measures. Overload, overheating, and high and low voltage situations will be warned with audible alarms. Besides, a small display is there to always notify you about the current and frequencies.

The risk of this inverter lies in not having enough reviews from Amazon. However, we have tested it in our lab and didn’t have any issues with it. But we can’t guarantee how far you can go with it in the test of time. For the price, it won’t hurt if the machine gives out after several month’s continuous uses.

Things We Liked

  • Low-cost option;

  • Size: 19 x 15 x 12 inches;
  • Model: 81-2010-12;
  • Weight: 55 pounds;
  • Outlets: 2 AC outlets;

To be honest, the basic features of this inverter are nothing extraordinary. Besides, it is the most expensive pure sine inverter of its class with a 2000 watt capacity. Despite that, it ranked in our list because of its longevity. Very few people are interested in fixing inverter-related problems while they are away from home enjoying a vacation.

For those, there is no alternative to this Xantrex inverter. I wonder if these are made of alien technology, but I have heard reviews that people use these inverters for almost over a decade without a hitch.

This inverter has 2 AC outlets to meet most of your demands from running the freezer to a laptop. Though the capacity is low, the surge rating is very high which is really handy to kickstart any motor like a fan or blender and machines alike.

Its price, size, and weight are also very high. So it is only suitable for mounting in a home or vehicle, neither highly portable nor frequently movable

Things We Liked

  • Very easy to install;
  • Durable;
  • Suitable for deep cycle batteries;
  • Long-lasting;

6. PowerBright 4000 Watt Power Inverter (PX4000)

  • Power type:  not specified;
  • Capacity: 4000 Watt;
  • Size: 15.6 x 7.6 x 5.4 inches;
  • Weight: 11.7 Pounds;
  • Input Voltage: 12 Volts;

To get the advantage of its 4000-watt capacity, this inverter has 4 outlets with it. This unit is the most powerful on our list, but the price is surprisingly budget-friendly. The 8000 watts peak power, is enough to run several household appliances during an emergency, camping, or simply a power cut.

This inverter is protected from overload, overheating, and short circuits. High or low voltage is warned by an alarm and the auto shut-down feature saves the unit from collapsing during severe situations.

There is an additional cost of a lithium-ion battery to charge the inverter if you don’t already have one. Besides, there is a risk of not getting enough power from this device for the expected time.

Because, for the price, quality or durability should be difficult to maintain. However, this unit has got a mixed review from Amazon. My realization is, using heavy and motorized equipment with caution will lengthen the life of this inverter.

Things We Liked

  • High capacity;
  • Comes with 4 outlets;
  • Durable case;
  • Noise-free;
  • Reasonable price. 

Things We Didn’t Like

  • Weight: 6.57 Pounds;
  • Outlets: 2 AC outlets.

Even the most expensive inverters can give you a headache if the customer service is not responsive to your problems when you need it most. So, I prefer purchasing inverters based on their customer service and warranty options so that if anything goes wrong, you can claim free service if not a replacement.

Considering these points, I decided to incorporate this POTEK inverter despite its generalized features. The second cause is, it is durable and does not cause problems for over a year of use.

You will get two outlets to use its 3000-watt power in various ways. It has all the protective measures you will see in any conventional inverters in the market. The added benefits are, it is lightweight, small in size, and affordable.

Things We Liked

  • Backed by a long warranty;

  • Model: PI 2000W;
  • Weight: 10 pounds;
  • Outlets: 3 AC outlets, 1 2A USB Port;

The key point of using an RV inverter is to power up devices and machinery off-grid, not draining power by the inverter itself. This problem basically arises with thermally protected inverters with a cooling fan attached.

However, this Potek inverter is the most energy-efficient thermal-protected inverter that will stay cool but won’t drain its charge using its fan. Because the fan starts when the inverter reaches a certain temperature. It is the feature that I liked most about this inverter.

The second most convenient thing is three AC outlets. Mostly, more powerful inverters come with 2 outlets and we end up using an additional plug to use multiple devices. 3 outlets will eliminate the need for an additional plug.

This unit has gained popularity throughout Puerto Rico after cyclone Maria. People relied on it for survival after a power cut that lasted for months. Some even used a charge controller to get the inverter charged from solar panels. What can be more promising than that during emergencies?

Things We Liked

  • Energy efficient;
  • Cheap price;

Things We Didn’t Like

  • Any remote control panel is not included in the package.

Should Overhaul RV Inverters?

Inverters/Chargers are a major overhaul from converters. Assuming you do a ton of boondocking or setting up camp off-matrix, this is an unquestionable requirement. We suggest measuring your inverter and buying from a legitimate RV brand that will give you an energy-effective item with a strong guarantee.

What Type of Power Does an RV Power Inverter Provide?

An RV power inverter provides alternating current (AC) power from a direct current (DC) power source, such as a battery. This allows for the use of AC devices, such as appliances and electronics, in an RV or other vehicle that is not connected to a traditional AC power source. The inverter converts the DC power from the battery into clean, stable AC power for use with devices that require it.

What is the Most Proficient Inverter?

Just 26 individual solar inverters are evaluated at either 98 or 98.5% effectiveness. SMA has been around since 1981 and is by all accounts the unmistakable innovator in assembling best-in-class inverters for sunlight-based applications.

How Many Watts Do I Need for an RV Inverter?

Actually, it depends on how much power you’re planning to draw from it. For example, a cell phone draws highly 50 watts, LED lights draw nearly 25 watts, and fans draw 75- 120 watts. Whereas, a toaster draws 800- 1500 watts or a toaster oven may draw 3000 watts. So deciding how many appliances and devices you want to run with it will help you to choose the inverter that you need.

Which Inverter Will Be Better for Me, Pure Sine or Modified Sine?

It depends on what type of devices or appliances you’re planning to run with it. If you want to run ceiling fans, vacuums, hair dryers, and light bulbs, modified sine will work great.

If you’re planning to operate computers, HD TVs, satellite receivers, or other smart devices, pure sine will be the best choice.

How Can I Use My RV Inverter?

One of the most interesting things about RV inverters is they are so easy to operate. After installation, you simply need to turn it on and connect the devices or appliances you want to power up.


Selecting the best inverter ensures you a smooth and uninterrupted power supply at your home or camp. But choosing the right one is a bit tricky as you’ll find so many options to choose from.

That’s why I’ve tried to simplify the process for you to choose the one. Just carefully follow the instructions, match them with the available inverters and you’ll end up with the one you need. You can also check the list I’ve mentioned with specifications. They are the most popular items in today’s world.

The most important thing you need to remember for buying an inverter is never to compromise with the price if you want a smooth supply and use it for a long time.
