How to Choose the Perfect RV Generator: A Complete Buyer’s Guide
Choosing a generator isn’t just about finding the highest wattage for the lowest price. It’s about matching a machine to your lifestyle, your rig’s specs, and the kind of camping you do most often. Here’s how to make that decision, step by step.
Step 1: Calculate Your Power Needs
Before you buy anything, you need to know how much power your RV requires. Every appliance has two wattage ratings: starting (surge) watts and running watts. Devices like air conditioners and microwaves need an initial burst of power to start up, which is why starting watts are often much higher than running watts.
Here’s a quick reference for common RV appliances:
- 13,500 BTU AC: 2800–3000W starting, 1500–1800W running
- 15,000 BTU AC: 3300–3500W starting, 1800–2200W running
- Microwave: 1000W running
- Coffee Maker: 800–1200W
- RV Fridge: 600W (startup), 180W (running)
If you have a 30-amp service RV, your max wattage capacity is 3,600W (120V x 30A). A 50-amp RV can draw up to 12,000W, but you’ll rarely need that unless you’re running dual air conditioners and heavy-duty appliances.
Step 2: Pick Your Fuel Type
Fuel choice can dramatically affect usability, cost, and maintenance.
- Gasoline is widely available and delivers high power output, but it degrades quickly and requires carburetor maintenance.
- Propane burns cleaner, has an indefinite shelf life, and can often tie into your RV’s onboard tanks. However, it produces slightly less power than gasoline.
- Solar/battery stations offer silent, emission-free power but are expensive and limited in wattage output. They are best for light-duty needs.
- Dual-fuel models let you switch between gas and propane, offering the best of both worlds. They’re increasingly popular among RVers who want fuel flexibility in remote areas.
Step 3: Understand Must-Have Features for RV Use
- Noise Level (dBA): Look for generators that operate under 60 dBA to meet campground rules and avoid irritating neighbors.
- Portability: Some RVers prefer two lightweight units (like Honda EU2200is) that they can carry solo over one heavy 100+ lb generator.
- Inverter Technology: Inverter generators produce clean power, safe for sensitive electronics like laptops and TVs.
- Parallel Capability: This feature allows you to connect two smaller inverter generators to double the output, which is very handy if you want flexibility.
- Remote Start: This highly requested convenience lets you start your generator without stepping outside, which is especially nice on cold or rainy mornings.
CARB Compliance: If you camp in California or want a more eco-conscious option, make sure your generator is CARB-certified.
The 5 Best Portable Generators for RVs: In-Depth Reviews
1. Honda EU2200i – Best for Quiet, Reliable Power
Honda has long been the gold standard in inverter generators, and the EU2200i continues that legacy. It’s virtually whisper-quiet, running as low as 48 dBA, and weighs just 47 pounds, making it one of the most portable and reliable options available. While its 2200 starting watts aren’t enough to run a 15k BTU AC on its own, many RVers pair two units in parallel to handle heavier loads. This generator is ideal for boondocking, minimalist campers, or those prioritizing silence and reliability over raw power.
Why RVers Love It: Forum users rave about how easy it is to maintain and how reliable it is even in extreme temperatures. It’s also one of the most fuel-efficient generators, offering up to 8 hours of runtime on less than a gallon of gas.
2. Champion 4500-Watt Dual Fuel – Best Value Overall
This model hits the sweet spot between price, power, and versatility. With 4500 starting watts and the ability to run on either gasoline or propane, it can power a 15k BTU AC unit and still leave room for your fridge and microwave. It includes a remote start feature, making it super convenient for solo travelers or older RVers who don’t want to yank a pull cord every time.
Why RVers Love It: Users frequently mention that this Champion model offers features you’d expect from higher-end models at a fraction of the price. It’s also built with RV-ready outlets (TT-30R), meaning no extra adapters are needed.
3. Westinghouse iGen4500DFc – Most Powerful Dual Fuel Inverter
The iGen4500DFc is a beast among inverter generators. It delivers 3700 running watts, perfect for larger RVs with multiple appliances. It also has a digital data center that displays remaining runtime, fuel level, and output. While it weighs over 100 pounds, the wheels and telescoping handle make it easier to transport than expected.
Why RVers Love It: This generator is popular among fifth-wheel owners and those who need serious power. It’s quiet for its size (just 52 dBA) and delivers consistently clean power for electronics.
4. Jackery Explorer 3000 Pro – Best Solar Generator for Silent Power
If you want silent operation with no fumes or fuel, the Jackery Explorer 3000 Pro is your best bet. As a battery-powered station, it’s ideal for running fans, lights, laptops, and small appliances. You can pair it with solar panels for renewable charging or recharge from shore power or your vehicle.
Why RVers Love It: This generator is the darling of vanlifers and eco-conscious campers. It can be stored inside your rig, charges devices quietly, and requires no maintenance. Just be realistic, this won’t run your air conditioner for hours on end.
5. Generac GP3000i – Best Lightweight Budget Option
Don’t let the low price fool you, the GP3000i is a capable generator for weekend trips or smaller RVs. With 3000 starting watts and quiet inverter technology, it’s perfect for running essentials like your fridge, lights, and TV. It’s also compact and easy to carry, weighing under 60 pounds.
Why RVers Love It: Many reviewers say it’s the perfect starter generator. It doesn’t have dual fuel or remote start, but for the price, you get clean, consistent power from a trusted brand.
Frequently Asked Questions About RV Generators
What’s the difference between an RV generator and a portable generator?
RV generators are typically built into high-end motorhomes, while portable generators are standalone units. Many portable generators today are “RV-Ready,” meaning they come with the correct TT-30 or 14-50 outlets for plugging directly into your rig without additional adapters.
Will a 3500-watt generator run an RV air conditioner?
Yes, in most cases. A 3500-watt generator can handle the surge required by a 13,500 BTU AC unit. However, always double-check the specs on your AC. Installing a soft start device can reduce the startup surge, making it easier for mid-size generators to handle cooling loads.
Should I get one large generator or two smaller ones in parallel?
This depends on your physical needs and use case. Two Honda EU2200is are easier to carry and offer redundancy. You can run one for light loads and fire up the second when needed. But a single Westinghouse or Champion generator is simpler to manage, especially for those who prefer one unit and fewer connections.
What is the best generator for an RV?
The Champion 4500-Watt Dual Fuel offers the best mix of power, features, and price for most RVers. If you need ultimate quiet, the Honda EU2200i is the winner. For silent power with zero emissions, go with the Jackery Explorer 3000 Pro.
What generator is best for RV camping?
For full-time or boondocking RVers, a dual-fuel inverter generator like the Westinghouse iGen4500DFc provides reliable, powerful performance with flexibility. For casual campers, something lightweight like the Generac GP3000i may be all you need.
What is the best solar generator for your RV?
The Jackery Explorer 3000 Pro is currently the best solar generator for RVers. It offers a large battery bank, clean power, and versatile charging options. Just know it’s best for light-duty use and won’t run heavy appliances for long.
Are diesel RV generators the best choice?
Diesel generators are typically built into Class A motorhomes and are ideal for full-time, high-power users. But they’re rarely portable, expensive, and overkill for most towable RV owners. A dual-fuel portable model is likely a better fit if you’re not in a diesel pusher.
The right generator can unlock total freedom, whether parked in a quiet forest clearing or dry camping in the desert. By understanding your power needs, comparing fuel options, and focusing on real-world use cases, you can find a model that won’t disappoint when you’re far from civilization. Whether it’s the whisper-quiet Honda EU2200i, the all-in-one value of the Champion 4500, or the ultra-clean power of a Jackery solar station, there’s a perfect fit for every kind of RVer.
