Best 50 Amp Generator for RV – 2025 Reviews

First things first—let’s talk about what 50 amps actually means for your RV. A 50 amp service provides up to 12,000 watts of power (50A × 240V), but most generators labeled as ’50 amp’ have outlets that can deliver this while their actual running wattage might be lower. You need to match your generator’s running watts to your RV’s typical load, which usually includes air conditioning, refrigerator, microwave, and charging devices.

As a rule of thumb, look for at least 8,000 running watts to comfortably power a 50 amp RV with multiple appliances running simultaneously. Don’t get fooled by peak wattage numbers—what matters is sustained power delivery.

This is where tri-fuel generators really shine. Gasoline is widely available but has a shorter shelf life and can be messy. Propane burns cleaner and stores indefinitely, making it great for emergency preparedness. Natural gas requires a fixed connection but offers unlimited runtime if you’re stationary.

I always recommend tri-fuel capability for RVers because it gives you flexibility depending on your location and fuel availability. During my testing, being able to switch fuels saved me multiple times when gasoline was scarce or propane tanks were empty.

Nothing will make you unpopular faster than a loud generator in a quiet campground. Look for models labeled as ‘quiet’ or ‘inverter’ generators, which typically operate between 60-68 decibels—about the volume of a normal conversation. Open-frame generators are usually louder but more affordable, while enclosed inverter models are quieter but pricier.

Most campgrounds have noise restrictions, so investing in a quiet generator isn’t just about being considerate—it’s about compliance. The generators we’ve selected all operate at reasonable noise levels for RV use.

Let’s be honest—generators are heavy, often weighing 200+ pounds. While wheels help, you’ll still need to consider how you’ll load and unload your generator from your RV or storage area. Look for models with sturdy wheels and handles that make movement manageable.

Also think about storage space in your RV. Some generators have more compact designs than others, and every square inch counts when you’re living on the road. Measure your available space before making a purchase.

Carbon monoxide sensors are non-negotiable for RV use where generators are often run in semi-enclosed spaces. Look for models with automatic CO shutdown features. Other important safety elements include low oil shutdown to protect the engine, overload protection to prevent damage to your appliances, and weather-resistant outlets with protective covers.

I never recommend using a generator without proper ventilation, even with CO sensors. Always position your generator downwind and at least 20 feet from your RV with exhaust pointing away from living areas.

Electric start and remote control might seem like luxuries, but they’re incredibly convenient when you’re dealing with bad weather or don’t want to leave your RV. ATS readiness (Automatic Transfer Switch) allows for seamless power switching during outages, though it requires additional equipment.

Digital displays that show runtime, voltage, and load levels help you monitor your power usage and plan accordingly. USB ports for charging devices directly from the generator are also handy additions for modern RVers.

For a 50 amp RV, you’ll want a generator with at least 8,000 running watts to handle typical loads like air conditioning, refrigerator, and microwave simultaneously. While 50 amp service can theoretically handle up to 12,000 watts, most RV appliances don’t draw that much continuously. The generators in our review all meet or exceed this requirement, giving you plenty of headroom for comfort.

Yes, all three generators we recommend offer tri-fuel capability, meaning they can run on gasoline, propane, or natural gas. Propane is actually a great choice for RVers because it burns cleaner than gasoline, has an indefinite shelf life, and is often readily available at campgrounds. Just make sure you have the proper hoses and connectors for your propane tanks.

The quietest 50 amp generators typically operate around 60-68 decibels, which is comparable to a normal conversation. Inverter generators like the ones we’ve selected are significantly quieter than traditional open-frame models. Most campgrounds have noise restrictions, usually requiring generators to be below 60-65 dB during quiet hours, so choosing a quiet model is essential for compliance and good neighbor relations.

Running watts refer to the continuous power a generator can deliver, while starting watts (or peak watts) represent the temporary surge power needed to start motor-driven appliances like air conditioners. Air conditioners might need 2-3 times their running wattage briefly when starting up. Always size your generator based on running watts for sustained operation, but ensure it has enough starting watts for your largest appliance.

Yes, you’ll need a 50 amp generator cord with the appropriate connectors. Most 50 amp generators use a NEMA 14-50P plug, while RVs typically have a 50 amp receptacle. The cord should be heavy-duty and rated for outdoor use. While we focused on generators in this review, having the right connection equipment is crucial for safe and reliable power transfer to your RV.
