Generators for RV Buyer’s Guide

What to Look for When Buying a Generator for Rv

You won’t always find camps with full utility hookups. Dry campers, for example, should set out fully equipped with supplies, including a reliable source of power. A generator for camping makes an excellent solution, but there is a need to choose one that matches your camping needs. It can be daunting for a rookie camper to buy generators for camping, so we have outlined essential things to consider when buying the equipment.

Type of Generator

There are two types of RV generators in the market today: the conventional and the inverter generator. The first model is relatively easy to use and is powered by gas, propane, or diesel. It uses an alternator to convert mechanical energy to electrical current.

Conventional generators are relatively affordable but need to operate at a constant rpm to produce the current required by the appliances. As such, if the motor speed fluctuates, the current also slows down, causing damage to the appliances.

Inverter generators are ideal for campers looking for an rv generator that can power electronics like TVs, microwaves and computers. These portable generators are integrated with a recent technology that converts AC produced by the generator to DC.

The current is the converted to clean AC voltage to produce a constant flow of electric current. The primary advantage of these RV generators is that they can change the motor speed depending on the demand. Additionally, campers can connect two inverters to increase output.

Inverters also have a more compact build compared to traditional generators because they have a smaller fuel tank. However, they have a short run time.

Type of Fuel

The power source depends on the type of travel trailer you are using. If using towables like teardrop trailers, small travel trailers, and egg camper trailers, then you may not need a fuel specific portable generator. RV-specific generators are categorized based on the type of fuel used to power them.

Propane-based generators are the best rv trailers as they are easy to maintain, quiet, and have a long run time compared to other generators. However, they don’t have as much power as diesel or gas powered RV generators.

The other kind is the diesel-powered generator used to power Class A motorhomes. They produce lots of power, are more stable, and are a cleaner alternative compared to gas powered generators.
Gas generators are more powerful than propane-based appliances. They are also readily available and easy to refill. However, they need a little more maintenance than propane and diesel-based generators. Additionally, the fuel needs to be emptied to avoid clogging up the generator

Camping Ground

Camper Van

The right generator for your RV largely depends on its application, i.e., whether you want to camp or boondock on the camping grounds. Boondocking refers to camping on free sites away from camping facilities; thus, your generator has work extra hard to keep the RV operational. However, if the travel trailer is equipped with a complete solar system that can keep lights and other appliances running, then you may not need extremely powerful generators.

Camping on campgrounds, however, is somewhat different as the areas are already equipped with 30 Amp outlets. A 30 Amp power source can support most of the appliances in the RV running; hence no need for a powerful generator.

However, it is imperative to research the campgrounds in advance as some have 15-20 Amp power sources, which may not provide enough power to power more than one appliance.

Type of Camper: Full-timers Vs. Weekenders

The amount of time you plan to use the RV also determines the kind of generator to use. Full-timers live in the trailer year-round; hence use a generator more than campers using a recreational vehicle. As such, you need to spend a little more money on high-quality generators you can rely on for many years.

Weekend campers usually spend a night or two on the recreational vehicle; hence need a small portable generator to enjoy its full use.

RV Generator Applications

What appliances does your RV have, and how much power do they need? Most RVs are designed to power a fan, lighting, furnace, stove, and a stereo. However, campers who want to use everything in the RV, including an air conditioner, microwave, and 120-volt outlets, need an external source of power.

Also, if you are using your RV heavily, the batteries drain quickly, hence the need to have a generator to charge them up. The rule of the thumb is never to allow your RV batteries to drain more than 50% of their capacity. An extremely low charge can cause permanent damage.

Also, determine if you want a unit that can function as a backup in case of a power outage. A large generator comes in handy in places that experience frequent outages while a mid-sized unit helps where there are short-term outages.

Size of the Generator

The right size of the RV generator largely depends on its applications. The first step is to find out the number of watts required for the most power-consuming appliance. Generally, there are three RV generator sizes:

  • Small Generators: These are recreational generators that produce up to 2,000 watts. They weigh less than 60 pounds making an appealing alternative to anyone who doesn’t need a heavy device. A 2,000-watt generator can power up a 10,000 BTU air conditioner
  • Mid-Size Generator: It has a weight range of 80-150 pounds and has a power output of 2,500-3,500 watts. It is an excellent option for users looking for a quiet generator that can operate for extended periods and support a 15, 000 BTU AC
  • Large Generator: Weighing up to 250 pounds, it is the largest class of generators. With a power load of more than 5,000 watts, it is powerful enough to power even the most powerful appliance in the RV

Noise Level

Noise is another essential factor to consider when camping with a generator. This is because most parks have outlined regulations as to the amount of noise generators should produce within a set distance (usually 60 dB at 50 feet).

Luckily, most modern generators are pretty quiet. It would help if you also looked at the quality of the muffler to determine if it contains the sound effectively. Alternatively, look for generators that can store charge, so they don’t produce noise or fumes during use.

Permanent Vs. Portable Generator

Portable generators are ideal for those going for camping or tailgating. However, if you are looking for the convenience of a permanent generator purchase, go for an equipment that can be installed directly into the RV unit. This kind is more expensive, but it is easier to use.

Tank Capacity

Determine how long the generator operates and the amount of power it needs. Some generators adjust the engine capacity automatically based on the load to enhance fuel efficiency.

Tech-Based Features

Look for tech-based features that make it easier to use the generator. For example, some generators use an electric remote start to launch them even when you are 10 or more meters away. Another handy feature is the LED screen to help you track essential stats like low fuel warning, run time, and shut down when there is not enough fuel in the tank.

The economy mode is another useful feature that increases the efficiency of the generator and its run time. It works by adjusting the engine to meet the required electric load, reduce fuel use and emissions when you don’t need the equipment’s full power.

What Size Generator Do I Need for My Rv?

Several factors determine the size of the RV generator you need. First, determine the running capacity of the generator and that of your RV’s appliances. Most average RV air conditioners run at 1,200 watts.

Also, factor in the starting watts because refrigerators and AC units use an induction electric motor that requires a startup load. The load is necessary for a short period to help the appliance transition to normal operational wattage.

Since the appliances have an auto shut-off feature, the generator needs to peak a load capacity that supplies the additional startup load for a short time. Other sensitive electronics like chargers, TVs, lights, and sound system don’t draw too much current, hence may not need startup current. If the generator can provide adequate power for high-wattage appliances, low-watt devices are already covered.

What Is the Best Generator for Rv Use?

Strom Generator

Westinghouse iGen4500 super quiet portable inverter generator is the best for RV use. It has a power load that keeps the equipment running for 12-18 hours, which is more than enough for complete off-grid camping.

A hybrid generator like the Champion RV Ready Portable Generator is also a good buy for RV use. The dual-fuel engine allows you to use gas or propane to power the equipment so you can never run out of power when dry camping.

How Many Watts Does It Take to Run an Rv Air Conditioner?

The minimum wattage of the generator is equal to the start load of an air conditioner. Most air conditioners come in two sizes, i.e., the 13,500 btu and 15,000 btu. The larger needs a starting load of 3,300-3,500W, and running watts of 1,300- 1,500W. The smaller air conditioners need a lower starting wattage of 2,800-3,000 W and running watts of 1,500-2,000 watts.

How Large Should a Generator Be to Power a 30 Amp Rv?

A 30-amp RV needs a 3,000-watt generator. To find out the power needs of a 30-amp RV, add the amps requirements of all the electrical requirements, and multiply the total by 120. For example, if you have an AC with a running power of 12 amps, add the power of other items in the RV like a fridge, TV, bulbs, and coffee maker.

If the sum of their running power is 24 amps, multiply by 120V to find out the average running power. According to our example, your 30-amp needs 2,880 watts, then a 3,000-watt generator like the Honda EU3000iS Portable Inverter is the best option. Make a provision for the start load and the running power when choosing the generator.

Can You Drive an Rv With the Generator Running?

Yes. Campers run the equipment while driving to keep the AC unit operational during hot days. Make sure the equipment is installed correctly to avoid causing accidents.

What Is the Difference Between Running and Surge Watts?

Running watts is the continuous power required to keep the appliance operational. It also refers to the most watts the generator is designed to produce regularly.

Surge watts is also referred to as the starting load. It is the extra power required to start electric appliances like refrigerators and air conditioning units. The surge wattage is higher than the running watts.

What Maintenance Procedures Does an RV Generator Need?

Even the best RV generator needs regular maintenance. Some tips to keep your equipment in top-notch condition include:

  • Inspect the hour meter: It shows the amount of time the equipment has been running and determines the frequency of oil changes. Keeping track of the generator’s run time prevents future service problems
  • Ramp up the generator regularly: If you have stored your RV during the off-season, you still need to ramp it up for an hour every three to four weeks to prevent the fuel from hardening. Also, turn on the air conditioner and other large appliances at 50% load capacity to make sure it can still support them
  • Change fuel, oil, and filters: the equipment should have an oil change after the first 50 hours of use, then 150 hours after. The oil filters also need to be changed as they affect the fuel efficiency of the generator. The coolant should be topped up as well
  • Avoid removing the covers: The equipment may overheat when running, hence the need to cool it off. Removing the covers is counterintuitive as it may cause engine problems. This is because the covers are fitted to enhance the flow of air
  • Check the exhaust system for fuel leaks and tighten any loose parts
  • Disable the remote start components when storing, refueling, or parking
  • Ensure the exhaust fumes are blown away from the camping site
  • Avoid storing rags, fuel, oils gas, and other flammable materials near the generator


Your power needs to determine the type of portable generator you need. Inverter generators are most users’ favorite as they provide more stable electric current. That’s why our first two picks comprise inverter generators. Their features are nearly the same with the Westinghouse iGen4500 Super Quiet Portable Inverter Generator making the best buy for campers looking for a small, compact yet functional inverter generator.

However, if looking for RV generators from renowned brands, Honda EU3000iS Portable Inverter is the best buy. The brand is known for making high-quality products, hence its premium price. Campers shopping on a budget may find Champion Power Equipment 100555 RV Ready Portable Generator the best investment.
