What Size Generator To Run My RV AC?
Many RV generator purchasers have this concern on their minds. If you frequently boondock, getting the proper size generator is critical.
The size mainly relies on the number of devices you intend to run on the generator. It also depends on the highest wattage that such gadgets require.
You'll need more watts if you use many appliances in tandem. Most larger devices such as air conditioners and refrigerators require more watts.
In addition, they have more incredible beginning watts than continuous running watts. The BTU of the air conditioner will, in most circumstances, define the number of watts you require on your generator.
To power a larger 14,000 or 15,000 BTU air conditioner, you'll need a generator with over 3,000 watts. Smaller air conditioners, such as those rated at 5,000 BTU or 8,000 BTU, can be powered by a generator rated at 2,000 watts to 3,000 watts.
This calculation should also take into account other concurrent run appliances. You'll very certainly have several other smaller equipment or refrigerators operating in addition to the air conditioner.
As a result, add up the watts required by each device and choose a generator that is somewhat larger than what you may need.

Buying Guide
Power Output
The power requirements of your RV mainly rely on your electrical appliances' ratings and the number of devices you intend to use simultaneously.
It is not a good idea to turn on all of your devices simultaneously, as this can overload the circuit breaker. In most RVs, the air conditioning unit has the highest power demands of any device.
That's why when estimating how many watts does an RV air conditioner use; it is a piece of excellent equipment to seek.
Most 13,500 BTU RV AC unit watts have 2,700 beginning watts and 1,200 operating watts. Your needed starting and operating wattage will differ, depending on whether you have a bigger or smaller air conditioning machine.
If you want to use a portable generator for RV air conditioners, ensure the generator has enough wattage to meet your unit's requirements.
Fuel Type
Many portable AC generators are gasoline-powered. Some are capable of running on propane or gasoline. Some of them even operate on diesel.
When a battery pack's power capacity is low, the final type you are aware of connects to it to refuel. When buying the best generator for a camper or an RV, the type of fuel used is crucial because it's your most significant ongoing expenditure.
The optimum fuel sort for you is determined by your location and the changing pricing of various fuels in that location. That's why many people with financial means do so and acquire a "dual fuel" inverter generator.
These generators run on either propane or gasoline, although they are often more costly than gasoline-only versions. Having said that, if you acquire one of those generators, it's always best to choose to use the less expensive fuel source.
Just keep in mind that based on which energy source you choose to run a dual-fuel generator, energy ratings may differ.
Size Of Fuel Tank
The larger capacity of a generator's fuel tank determines the longer it can operate. The length of time it takes for the generator to function depends on the amount of load you put on it.
However, in most situations, a larger gasoline tank means more running time. The main disadvantage of a bigger fuel tank is the additional weight to the generator when it's complete.
If mobility is more important than running duration, choosing a generator with the most prominent fuel tank available may not be a top concern.
Parallel Capacity
A generator's parallel capacity allows it to connect to another (through a connection kit, usually provided separately). When these two machines are linked together, they may create more energy than either generator can produce on its own.
Even the most acceptable RV inverter generators do not always have enough beginning wattage for running camper air conditioner watts.
If you want to purchase an inverter generator for this purpose, ensure you choose one with parallel capabilities.
Noise
The majority of these transportable RV generators are far quieter than older generators. When functioning, they generally produce around 50 and 60 dB.
The quantity of noise emitted by a generator varies on the strain it is subjected to. Carefully read the small print to see how many decibels it generates under various loads.
Most marketing brochures state that the generator should be rated for a minimum decibel level at a third load. As a result, it's essential to know how much noise the same RV generator generates when it's fully loaded.
Portability
If you don't intend on permanently putting a generator beneath your RV, portability is essential.
The weight of these RV generators ranges over 100 pounds; thus, the ease (or difficulty) with which you can move your generator depends on the type you pick.
If you are searching for a more significant inverter generator, ensure it has tires and a handy handle. Although you need to carry it occasionally, being able to maneuver it makes your life much more straightforward.
It decreases the danger of damage associated with moving and lifting a big generator. Even the lighter the generators must have a handle to make them easier to maneuver.
Since inverter generators may be responsible for various purposes, opting for a portable type is a wise decision.
Warranty Information
Since many of these inverter RV generators are expensive, it's crucial to read the warranty data provided by each vendor.
All of these generators should come with some guarantee, although the specifics of each warranty may vary. Before purchasing a portable generator to run your RV, ensure you know the conditions of the manufacturer's guarantee.
It will determine your ability to have your generator repaired if problems develop. The worst-case scenario also determines if your RV generator will be replaced entirely by the manufacturer.
A more extended manufacturer warranty is preferable in general for giving you access to free replacement and repair for a longer length of time.
It also indicates the manufacturer's trust in their goods, which tells you much about the generator's quality before purchasing.
Ease Of Use
It is a crucial factor to consider, mainly if you are unfamiliar with fundamental electronics and engineering. The product that you can start with the touch of a button is the greatest for you.
Many RV generators available now are more advanced. They have automated power output regulators that adjust the amount of energy used by the device you're currently using.
Surge Protection
Surges in electricity may harm your gadgets and appliances, as well as RV generators. In the worst-case scenario, it may cause a fire.
So, when you buy RV generators, look for one with surge protection, or automatic voltage regulation, since these features may protect your equipment and keep the camping experience free of electronics-related issues.
Price
It takes more than simply looking at the cost of the generator to determine your budget, which you spend for an inverter generator.
You should also consider possible maintenance expenses, fuel usage, and the generator's projected lifespan.
It is also worth noting that prices change a lot. If a specific generator is now out of your price range, you might want to wait several days or shop around to see if you can locate a better offer.
