Benefits of RV Inverters

  • Use electronics on the go. One of the biggest advantages of using a power inverter is being able to use your electronics while camping. This includes the appliances in your motorhome and even some luxury items like your TV or computer. Traveling and relaxing with entertainment options is the best of both worlds
  • Connect to shore power. A power converter makes it simple to use shore power when available. Typical inverters give you easier access and convert from DC to AC power. This will give you the opportunity to use devices with regular plugs.
  • Keep your devices charged. While escaping the regular everyday city life, you still want to keep your devices charged, whether it's your phone for an emergency, a laptop to check in on work, or even a GPS to get to your next location. RV power inverters give you regular AC plugs and sometimes even USB ports to keep your devices charged. 

Types of Inverters

Square Wave

An older type of power inverter is called a square wave. Newer technologies have mostly replaced this method, but they are occasionally still available due to the low cost. These inverters can power small appliances or power tools, but overall they are limited in what items they can sufficiently run.

Sine Wave

The most common type of motorhome inverter is called a sine wave (sometimes called a true sine or pure sine inverter). The best RV inverters use this technology because it is the strongest and most advanced design. Sine wave inverters work with almost all appliances, making them ideal for mobile home use. While these inverters are great for their maximum power capabilities, they are also the most expensive.

Modified Sine Wave

Modified sine wave inverters have grown in popularity. These devices can effectively power most of your devices and appliances, and modified sine wave inverters are much less expensive than pure sine wave power inverters. The drawback is that these converters consume more battery power and don’t put out nearly as much power.

RV Inverter Pricing

  • Under $150: Smaller RV inverters can cost around $100. While this investment is the best price-wise, they generally have less power output and fewer options compared to premium models. 
  • $150 to $300: Some of the best RV power inverters land in this middle price range. These are usually 3,000-watt RV inverters and 2,000-watt inverters for RV use, and typical features include larger batteries, higher power output, and multiple outlets for easy use. 
  • Over $300: This premium price point is where you’ll find the best pure sine wave inverter for RVs. These inverters can run your entire motorhome and include helpful features like cooling protection, easy installation tools, or even solar panels. 

Key Features

Power Output

Having a power inverter that can't handle the products you want to use is a waste. The first thing you need to know is how much power you'll actually be using. For example, do you simply need to charge your devices or does the entire kitchen in your RV need electricity? Your inverter needs to have a constant output that is above the number of watts you expect to use but isn't producing so much extra power that it ends up being a waste of money. 

Safety Features

There are several potential issues that your inverter can run into, so having a device with built-in protection is very helpful. The most significant worry is overheating. RV power inverters produce a lot of heat while running, so it's crucial to find a product with cooling fans. Other electrical safety features include overload protection, an over-voltage alarm, under-voltage alarm, high-quality power surge protection, and a short-circuit prevention system. 

Easy Installation

Make sure you get an RV inverter that you can hook up yourself. There are several different ways to hook them up, and some need to be hard-wired. Some of the easiest to set up models are inverters that can plug directly into a 12V port with battery cables. You should also keep in mind where the inverter will go and whether or not the device comes with brackets. 

Other Considerations

  • Size: Some of the most expensive RV inverters are incredibly large and heavy. This is important to consider before you make a purchase because you'll want to plan out where the device will fit and if it is too bulky to be worth the price.
  • Price: Most of the time, inverters will be priced based on power output. However, this isn't the only important factor, and spending more money for extra power may not always be worth it. Consider your expected usage and what features are most important to you. 
  • Remote Control: Some RV power inverters come with a remote switch, both wired and wireless. While it may not be necessary, think about where your device will be placed and whether or not it will be easy to reach the manual on and off switch.

Best RV Inverter Reviews & Recommendations 2019

Best RV Inverter Overall: AIMS 8000 Watt Continuous Power Inverter

AIMS 8000 Watt Continuous Power Inverter
Amazon

The best power inverter you can buy is the AIMS modified sine DC inverter. One of the best features of this product is that it comes in multiple different sizes⁠—from 1,250 watts to 10,000 Watts. For the purpose of this AIMS inverter charger review, we'll be focusing on the 8,000-watt model as it has the best balance of features. 

This unit manages to pack a lot of power into a relatively small product. The AIMS inverter gives you 8,000 watts of continuous power and offers 16,000W of surge power. The device has built-in overload protection, thermal shutdown, a reverse polarity indicator, high-voltage protection, low-voltage protection, and a short-circuit transfer switch. Its 66 amps can work with appliances and power tools, and this converter's performance can be monitored via the LED lights. One stand-out feature of this model is the light-weight construction. It’s also the easiest to set up. 

Overall this is the best RV power inverter, but the AIMS model does have a few drawbacks. The biggest issue is that this is the most expensive option on the list, so someone on a tight budget should look for a different inverter. Also, the large fan used in this device is pretty loud compared to others.

Best RV Inverter Value: KRIËGER 1100 Watt 12V DC Power Inverter

KRIËGER 1100 Watt 12V DC Power Inverter
Amazon

When it comes to smaller and less expensive options, the best inverter for camping is the KRIËGER modified sine wave inverter. While this option has fewer watts than the others on the list, it's important to remember that the extra power may not be necessary. If you don't need to run all your appliances at once, it might be worth saving money with this capable little device. 

The overall size of the KRIËGER is a huge selling point. Power inverters can be bulky and take up a lot of your already limited space in an RV. This inverter has two USB ports, two AC outlets, an included remote switch, and an LED screen that displays battery power, wattage, voltage, temperature, and warnings. This product also comes with a three-year warranty, which is the longest on the list.

Despite being the best travel trailer inverter, the KRIËGER misses the mark in a few key areas. Most notably, this inverter has the lowest power output of any product on this list. Anyone looking to power several appliances at once shouldn't get this device. Also, this inverter can be prone to overheating.

Best RV Inverter Honorable Mention: ENERGIZER 4000 Watt 12V Power Inverter

ENERGIZER 4000 Watt 12V Power Inverter
Amazon

Another great RV power inverter that gives you a wide variety of device options is the Energizer modified sine wave inverter. This device can be ordered in a 100W size—which plugs into a vehicle's powerpoint—and the largest model is a 4,000W inverter (which is the model we’re focusing on in this review).

Energizer's 4,000 Watt 12V Power Inverter is a good alternative to the AIMS model because it shares a lot of similar features, but this a cheaper product. This inverter can convert 12 volt DC power to 120V AC Power. The fan used for this product is also much quieter than most RV inverters, and the device has a remote switch. You can power several devices at once with the two USB ports and four AC outlets. Energizer uses a built-in LED display to help you monitor input and output as well as emergency notifications and a battery indicator.

The biggest reason this product is not the number-one pick is that the AIMS converter outperforms it. The Energizer inverter is just as bulky as the AIMS inverter, while only producing half as much power. It is also much more expensive than the KRIËGER inverter.

Tips

  • Most likely, if you are hooked up to shore power, you can turn your inverter off. Most shore power comes through as AC power already, so the inverter isn’t necessary. This is not the case, of course, if the shore power you’re using is DC power. 
  • Modified sine wave inverters produce enough power to run appliances like refrigerators, ovens, and air conditioners. However, modified sine inverters are less efficient and won’t power anything with an electric motor to its full extent, so depending on your appliances, a pure sine inverter may be required. 
  • Be aware of your RV battery’s amps per hour as this will determine how long your inverter can run on the battery without draining all the power.

FAQs

Q: What does an RV power inverter do?

A: A power inverter takes the DC (Direct Current) electricity from your RV's battery and converts it to AC (Alternating Current) power. This allows you to power your regular devices and household products with the RV battery. 

Q: Is there a difference between an inverter and a converter?

A: Yes. While an inverter changes electricity style from DC to AC, a converter changes the form in the opposite direction (AC to DC). 

Q: How do I use an RV power inverter?

A: A great thing about power inverters is that they're very straightforward to use. After the initial setup (as required by your specific product), all you have to do is turn the inverter on and plug in whatever needs power. 

Final Thoughts

The best RV power inverter overall is the AIMS 8000 Watt Continuous Power Inverter. This device has the most options with the highest power output without being too bulky. 

If you don't need all that power and want a more affordable product, the KRIËGER 1100 Watt 12V DC Power Inverter is your best choice. This model is great for smaller power needs and still has some high-quality features.
