Powering your RV with a portable generator opens up a world of possibilities. Whether you’re dry camping miles away from the nearest hookup, weathering a power outage, or simply enjoying the flexibility of off-grid adventures, a portable generator is your ticket to comfort. But safely and effectively connecting your generator to your RV requires know-how.
Let’s look at how to hook up a portable generator to an RV.
How to Choose the Right Portable Generator
Before you start, selecting the right generator is key. Your RV’s power demands dictate the type of generator you need.
Wattage
- 30 Amp RVs: We recommend a generator with at least 3,500 watts to handle essential appliances.
- 50 Amp RVs: For rigs with dual air conditioners, aim for 6,000 to 8,000 watts. If you have three AC units, look for a 10,000+ watt generator.
Outlets
Most RVs use either a TT-30R (30-amp) or 14-50R (50-amp) outlet. Ensure your generator has the appropriate socket or invest in an adapter.
Surge Protectors
Protect your RV’s electrical system by using a surge protector. This device prevents voltage spikes that could damage appliances or circuits.
Pre-Connection Safety Checks
Safety always comes first. Before firing up your generator, perform these checks:
Inspect the Generator
- Oil and Fuel Levels: Top off as needed.
- Air Filter: Clean or replace if it’s clogged to ensure optimal performance.
Placement is Key
- Place the generator on a level, non-flammable surface like concrete.
- Maintain a minimum distance of 15 feet from your RV.
- Ensure the exhaust faces away from your vehicle and other campers.
Is It Compatible?
Verify that your RV power cord matches the generator outlet. Use an adapter if necessary to ensure a snug fit.
Step-by-Step Connection Guide
Now that your generator is ready, follow these steps to connect it to your RV:
Step 1: Start the Generator
Before plugging anything in, start the generator and let it run for at least 5 minutes. This allows the engine to stabilize and reduces the risk of power surges.
Step 2: Connect the Power Cord
Using a heavy-duty power cord, plug your RV into the generator’s outlet. If your generator outlet and RV cord don’t match, use the correct adapter.
Step 3: Add a Surge Protector
For added safety, place a surge protector between the generator and your RV’s power cord.
Step 4: Power Up Gradually
Turn on appliances one at a time to prevent overloading the generator. Start with essentials like the refrigerator or AC unit, and add other devices as the generator can handle.

How To Start a Portable Generator
Here are the six basic steps to start a portable generator:
- Check the oil and fuel.
- Turn on the fuel valve.
- Flip the switch to the On position.
- Flip the choke to the starting position.
- Pull the crank handle in a swift, smooth motion.
- Adjust the choke to the running position.
Every portable generator is different. Some have crank handles or pull handles, like a mower. Inverter generators on the other hand have an electric start. Check the owner’s manual for a detailed guide to start your generator.
Let the generator run for at least 5 minutes before you plug in your RV or travel trailer. Starting a generator while plugged into the RV can damage the electrical system. Consider using a surge protector between your generator and the RV.
Once connected, be mindful of energy consumption. Don’t run any high-wattage appliances all at once. This includes AC units, microwaves, etc.
Common Questions and Troubleshooting
Do I Need an Adapter if My Generator Doesn’t Have a 30-Amp Outlet?
Yes, you will need an adapter to connect devices requiring a 30-amp outlet if your generator lacks one. Ensure the adapter matches your generator’s available outlets and supports the required amperage.
What if My Generator Struggles to Power All Appliances?
Your generator may be overloaded if it struggles to power all appliances. Reduce the number of connected devices or prioritize essential ones. Check the generator’s wattage rating to ensure it matches your power needs. If the issue persists, consider upgrading to a higher-capacity generator.
Can I Use the Generator to Charge the RV Battery?
Yes, you can use a generator to charge an RV battery. Connect the generator to the RV’s built-in converter or use a separate battery charger compatible with the generator’s output. Ensure the generator provides the correct voltage and amperage for safe charging.
Shutting Down and Refueling
When it’s time to turn off or refuel your generator, follow these steps for safety:
- Turn Off RV Appliances: This prevents electrical surges when disconnecting.
- Disconnect the Power Cord: Unplug your RV from the generator.
- Power Down the Generator: Follow the instructions in the manual. This typically involves switching to “Off” and closing the fuel valve.
- Cool Down Before Refueling: Wait 5-10 minutes after shutting down to avoid spills or accidents.
RV Generator Safety Tips
- Carbon Monoxide Precautions: Never run your generator in enclosed or poorly ventilated areas.
- Routine Maintenance: Clean the air filter, check oil levels, and inspect for wear regularly.
- Follow Campground Rules: Be mindful of noise limits and designated generator hours.
- Protect It From the Elements: Use a cover to protect your gener
