Your Essential Guide to Buying the Best RV Generator
Choosing the right RV generator powers your adventures. It keeps your lights on and your snacks cold. This guide helps you pick the perfect one for your travels.
Key Features to Look For
A good generator has several important parts. You need to check these before you buy.
Power Output (Watts)
Generators are rated in watts. This tells you how much electricity they make. Think about what you need to run. A small camper might only need 2,000 watts. A large RV with air conditioners needs 4,000 watts or more. Always buy a little more power than you think you need. This gives you room for extra gadgets.
Fuel Type
Most RV generators use gasoline, propane (LPG), or diesel. Propane burns cleaner and lasts longer in storage. Gasoline is easy to find. Diesel is very fuel-efficient for long trips. Some advanced models run on dual or even triple fuel sources. Consider which fuel is easiest for you to carry and use.
Noise Level (Decibels – dB)
Loud generators annoy neighbors at the campground. Look for generators rated under 60 dB for quiet operation. These are often called “inverter generators.” Quiet operation is a huge plus for a good user experience.
Inverter Technology
Inverter generators produce clean, stable power. This is vital for sensitive electronics like laptops and modern TVs. Non-inverter models can sometimes damage delicate equipment. Clean power is important power.
Important Materials and Build Quality
The materials used in a generator affect how long it lasts and how well it performs.
- Engine Components: Look for engines with durable parts, often made of cast iron. Better materials mean the engine runs smoother and lasts longer.
- Frame and Casing: The outer shell protects the engine from weather and road debris. A strong, powder-coated steel frame resists rust and damage.
- Copper Windings: In the alternator, copper windings handle heat better than aluminum. This improves efficiency and lifespan.
Factors That Improve or Reduce Quality
Quality isn’t just about the parts; it’s about how the unit works together.
Factors That Improve Quality:
- Automatic Voltage Regulation (AVR): This keeps the power output steady, protecting your appliances.
- Low Oil Shutoff: This safety feature stops the engine if the oil gets too low. This prevents serious engine damage.
- Extended Run Times: A larger fuel tank means you run the generator longer without stopping to refuel.
Factors That Reduce Quality:
- Poor Cooling Systems: If a generator overheats easily, its lifespan shortens.
- Cheap Plastic Components: Parts made from thin plastic break easily when exposed to vibration or sun.
- Complex Maintenance: If changing the oil or spark plug is very difficult, users often skip needed maintenance, reducing the generator’s life.
User Experience and Use Cases
How you plan to use your RV dictates the best generator choice.
Weekend Campers:
If you only camp on weekends and use basic lights and a microwave, a smaller, portable inverter generator (2,000–3,000 watts) works well. These are light and easy to move.
Full-Time RVers:
People living in their RVs full-time need reliability. They often choose built-in, permanently mounted generators. These units usually run on the RV’s main propane tank and are very quiet.
Boondockers (Off-Grid Travel):
Those who camp away from hookups need maximum efficiency. Dual-fuel or tri-fuel models are excellent here because they offer fuel flexibility. High-efficiency diesel models also shine in this use case.
Always check the weight and size. You must be able to safely store and move the unit. Easy-to-read fuel gauges and simple start buttons greatly improve the daily user experience.
RV Generator Buying Guide FAQ
Q: What is the difference between a conventional and an inverter generator?
A: A conventional generator makes power that can sometimes fluctuate. An inverter generator cleans that power, making it smooth and safe for sensitive electronics like computers and phones. Inverter models are usually much quieter too.
Q: How many watts do I really need for my RV?
A: Add up the wattage of everything you want to run at the same time. Air conditioners use the most power. A good rule is to take that total and add 20%. For example, if your total is 3,500 watts, look for a 4,000-watt generator.
Q: Is propane better than gasoline for an RV generator?
A: Propane is often preferred because it stores almost indefinitely without going bad. Gasoline can go stale in just a few months if left in the tank, which causes starting problems. Propane also burns cleaner, which is better for the engine.
Q: What does “starting watts” mean?
A: Starting watts (or surge watts) is the extra power needed for a short burst when an appliance with a motor—like an air conditioner or microwave—first turns on. You need a generator that can handle this surge, not just the running watts.
Q: How important is the noise level?
A: It is very important, especially in crowded campgrounds. Generators above 65 dB are considered loud. Look for models under 60 dB for peaceful camping experiences.
Q: Can I run my generator in the rain?
A: Most modern RV generators are built to handle light rain. However, you should never operate them in a heavy downpour or where water can pool. Always keep the exhaust area clear.
Q: Do I need to change the oil often?
A: Yes, regular oil changes are key to generator life. For light use, change it once a year or every 50 to 100 hours of operation. Check your owner’s manual for the exact schedule.
Q: What is “low oil shutoff”?
A: This is a safety feature. If the oil level drops too low, the generator automatically shuts down. This stops the engine from burning itself up due to lack of lubrication.
Q: Should I buy a portable or a built-in generator?
A: Portable generators are cheaper and easier to move for occasional use. Built-in (or “on-board”) generators are permanently installed, much quieter, and run off your RV’s main fuel supply, making them better for full-time RVers.
Q: How do I store my generator during the off-season?
A: If using gasoline, run the fuel dry or add a fuel stabilizer. Store the unit in a dry, covered area. For propane units, disconnect the tank and store the generator in a well-ventilated space.
