What is the best RV autoformer? Owning an RV can be challenging because of the costs and maintenance tasks that are involved. Electricity related issues are just one of many situations that RVers must deal with. Parks usually cannot handle the influx of RV users, all connecting into the shore power during peak times. As a result, fluctuations and under-voltage become a common problem.
The results of these inconsistencies in power can lead to costly damage to your electric equipment, so an effective prevention would be the installation of an RV autoformer. Since this plays a massive role in stabilizing your electricity, you must be mindful when selecting an RV autoformer. It might be another expense, but it is a smart and worthwhile expenditure that would lead you to save on costs in the future.

What Is An RV Autoformer And How Does It Work
A lot of people are confused about the difference between an autoformer and a surge protector. While it is true that both measures the voltage that goes into the RV, their primary responsibilities are way different. Some autoformers can function as both an autoformer and a surge protector.
Every RV owner should have a surge protector handy if you tend to travel and visit various RV parks and camping grounds. It is smart to have either a surge protector and autoformer regardless of whether it’s a combo system or two separate devices.
An RV autoformer, as the name suggests, is a combination of the words automatic and transformer. But for an RV, it doesn’t imply that it is an auto transformer. Yes, it is a confusing concept.
The main objective of RV autoformers is to increase the voltage that is going into your recreational vehicle when it determines that the voltage is too low. It will change the voltage, specifically the amperage relationship, and lower or raise the voltage as needed. Although it is often mistakenly called an autoformer, the right term should be a step-up transformer or also a voltage booster. An RV autoformer is not designed to take power from the park or camp. It also does not make electricity or affect the input voltage.
An RV autoformer running at the full output of 50amp will utilize 1 amp but will lead the appliances to cycle more frequently. This can also cause the system to run cooler and use a reduced amount of total power from the camp or park.
You must get your terminologies and definitions right and have a clear understanding because autotransformers specifically for RVs are considered illegal as per the National Electrical Code. Meanwhile, RV autoformers, like the Hughes RV autoformer, are perfectly acceptable because, again, it is not an autotransformer but an RV voltage booster.
Types Of RV Autoformers
Getting the correct autoformer for your RV is essential so it can function efficiently. You must obtain the one that suits your needs and be compatible with your RV and your electrical needs. Getting one that is lacking and wouldn’t regulate and boost the voltage is a waste of money.
There are different options of autoformers. Usually, it is categorized based on its overall electric current capacity and based on the features integrated on it.
The two main types of autoformers will be the 30 Amp autoformer and the 50 Amp when based on current capacity. Technically, you must investigate your RV’s current rating to know which one you need. Larger RVs with more electrical devices would be best to have a 50 Amp onboard.
The function is the same, but the main difference will be with the capacity since a 30Amp autoformer will have 3,600 Watts while the more significant 50 Amp has 12,000 Watts. Both can be designed to be portable and lightweight, too, depending on the model and manufacturer.
Another way that RV autoformers can be classified would be based on their features. There are the basic autoformers or just voltage controllers. Some are designed to have dual functions like both having the properties of being a surge protector and a voltage booster.
There is also the autotransformer, which only has a single winding compared to the typical transformer, which has two primary and secondary windings. As a result, voltage modifications are usually smaller in an RV autoformer when compared to a transformer.
Overall, consider the capacity of the RV autoformer before anything else. From there, you can slowly assess if it is a perfect fit for your RV or not. Also, it is best to purchase one with combo functionalities because it saves you the complexities of having two separate types of equipment.
Benefits Of Using An Autoformer For RV
Repairs and replacements on damaged RV appliances are stressful and not to mention a super expensive problem. This can easily be prevented by an autoformer which can stabilize the flow of electricity and prevent any damages to your electrical appliances.
Not all RVers are keen on investing in this equipment more because of the lack of awareness when it comes to its benefits. Below are some specific advantages of having an RV autoformer:
- You can slowly grow your financial savings. You don’t need to re-allocate a portion of the budgets to purchase new electrical devices for your RV destroyed by electricity and current-related problems.
- RV autoformers allows you to conveniently use your modern RV in older parks where the power pedestals are still not updated. You don’t need to drive for miles in search of the ‘newer’ parks saving you time and gas and a much-needed rest by the end of the day.
- This equipment can protect your recreational vehicle from polarity and phase reversals that might be brought about by incorrect power output installations.
- It gives your appliances a breather and prevents them from overworking. You might not be aware, but your electrical devices tend to work harder if the voltage they are getting is lower. Due to this, the amperage upsurges and may lead to the appliances and tools to malfunction. An RV autoformer can minimize the chances of this from happening since it will, by design, boost a low voltage once detected.
- Autoformers who have dual functions have an integrated surge protector that helps secure your RV from a power overload.
- There is no need to program and do calculations yourself because autoformers adjust automatically. You don’t need to worry about having the incorrect conversions. For example, A portable Hughes autoformer 50 amp can boost the voltage to up to 10% if it detects that the RV park’s power drops and goes below 117V. It will lower the amps automatically. Once the RV park’s power goes back to 118V, the autoformer will just let the power flow without any boost needed.
- By far, the most significant advantage of having an RV autoformer is the peace of mind knowing that your appliances and other electronic investments are safe every time you connect your camper at home or in an RV park site.
With just some of the benefits mentioned earlier, you can rethink your options and needs. Most likely, you will agree that this is much-needed equipment.
How We Picked
Owning an RV and getting it all equipped and comfy always comes with a lot of costs. Initially, it seems the flow of money would still be going out, but eventually, you’ll reap everything that you’ve invested. This is why you must be keen on making sure that your RV, including your electrical devices, is well protected.
One of the main concerns of RVers would be the destructive power fluctuations that are common in campgrounds and RV parks. This problem is extremely hazardous to your electrical devices. If unlucky and you end up connecting to a faulty park power, then you might as well say your goodbyes to all your electronics.
Therefore, getting an RV autoformer is essential, but you don’t just purchase the first one you see. Here are a few things that you need to consider when choosing your RV autoformer.
- UL Listed – it would be better if you get a model that is UL certified. This is one assurance that the product you will be buying is a quality autoformer capable of protecting your RV and appliances from the power surges. It is also a reasonable basis and indication that your choice will last for a long time.
- Joules Rating – this is one of the main factors that you need to consider before buying your RV autoformer. This will tell you the level or amount of protection you get from the product. This is the surge suppression capability of your autoformer. Go for a product that has a higher Joules rating because, with a higher rating, you won’t worry anymore about under-voltage or overheating.
- Amp Rating – you must make sure that the autoformer has the right amp rating for your RV. It should be the correct amount to function properly if your autoformer does not have any electricity running from it. Then it will not work as expected.
- Weight and Size – every available space is valuable in an RV. The last thing you should want is a cramped and uncomfortable recreational vehicle. Opt for an autoformer that is lightweight and compact; easy to move around from one RV ground to another. Do not sacrifice the quality of materials, though, just for the weight. Make sure that although light and compact, it is still solid and can work with the dynamic outdoor conditions, including the weather.
- Installation – you would prefer a system that is easy to install. For instance, if you are eyeing a Hughes, you should be able to rely on the instruction manuals and guides included in the Hughes autoformer install kit and set it up with confidence. To make the process more hassle-free, look for the plug and play units.
- Budget – set your budget and stick with it. There are ways that you can get discounts so you can take advantage of these opportunities. For instance, Hughes autoformer issues a price slash locally or online, then you can time your purchase. You can also use a Hughes autoformer coupon if you have one to save a couple of dollars.
