Let’s look at the wattage requirements for common RV appliances without further ado.
RV Appliance Wattage Chart
| Appliance | Running Watts | Startup/Max Wattage |
|---|---|---|
| Air Conditioner | 1300-2000 | 2800-3500 |
| Coffee Maker | 600-1000 | 600-1000 |
| Electric Frying Pan | 1000-1500 | 1000-1500 |
| Hot Water Heaters | 1000-1500 | 1000-1500 |
| Laptop Computers | 50-100 | 50-100 |
| Microwave Oven | 1000-1500 | 1000-1500 |
| RV Refrigerator | 150-200 | 600-1000 |
Remember that these are approximate values; actual wattages may vary for each appliance.
Bigger Generator, Bigger Gas Consumption: Finding the Balance
It’s important to remember that the larger the generator, the more fuel it consumes. While a bigger generator can handle more appliances, it may not be the most fuel-efficient option. Striking the right balance between power output and fuel consumption is crucial to minimize your expenses and reducing the generator’s environmental impact.
One popular generator that strikes this balance is the Predator 3500. This inverter generator is known for its fuel efficiency, quiet operation, and ability to power an air conditioner. It’s an excellent choice for travel trailer or 5th-wheel owners looking for a reliable, cost-effective power source.

Noise Comparison: Predator 3500 vs. Other Generators
Noise levels are essential when choosing a generator, especially if you camp in quiet areas or near other RVers. Let’s compare the noise decibels of several generators, including the Predator 3500 and various inverter and non-inverter options:
| Generator Model | Type | Noise Level (dB) |
|---|---|---|
| Predator 3500 (Harbor Freight) | Inverter | 57 |
| Honda EU2200i | Inverter | 48-57 |
| Yamaha EF2400iSHC | Inverter | 53-60 |
| Champion 4000-Watt DH | Inverter | 64 |
| Westinghouse WGen3600v | Non-inverter | 69 |
| DuroMax XP4400E | Non-inverter | 69 |
As a reference, normal conversation noise levels are around 60 dB.
As you can see, inverter generators typically have lower noise levels than non-inverter generators. The Predator 3500 is on the quieter end of the spectrum, making it an appealing option for noise-sensitive campers.
Choosing the Right Size Generator
Now that you know the power requirements of your appliances, it’s time to pick the right generator. Here’s what to consider:
- Total wattage: Add up the running watts of all the appliances you plan to use simultaneously. This will give you an idea of the minimum power output your generator needs.
- Startup wattage: Remember that some appliances, like air conditioners and refrigerators, require more power to start. Make sure your generator can handle its maximum wattage.
- Noise level: Look for an inverter generator with low noise, especially if you plan to camp in quiet areas or near other RVers.
- Fuel type: Consider a generator that runs on diesel fuel for better fuel efficiency and longer duration.
- Extra watts: It’s always a good idea to have extra power if you need to use additional appliances or charge your RV batteries.
Tips for Efficient Power Management
To make the most of your power sources, follow these simple tips:
- Use energy-efficient appliances that require less energy.
- Turn off appliances when they’re not in use.
- Use solar panels to charge your house batteries and reduce the load on your generator.
- Monitor your generator’s fuel consumption and refill it as needed.
The main difference between 30-amp and 50-amp RVs is the amount of power they can handle. A 30-amp RV typically operates on a 120-volt electrical system, while a 50-amp RV has a 240-volt system, allowing for more appliances and higher power usage. If you’re unsure whether you need a 30-amp or 50-amp generator, check your appliances’ amperage draw and electrical needs.
Popular Generator Brands: What to Look For
When shopping for the best generator for your RV, consider these popular brands known for their reliability, performance, and customer satisfaction:
- Honda
- Yamaha
- Generac
- Champion
- Westinghouse
Look for generators with features that suit your needs, such as low noise levels, fuel efficiency, and portability. Reading customer reviews and comparing different models can also help you make an informed decision.
Tips for Choosing the Right Generator Size for Short Periods
If you only need a generator for short periods, it’s still essential to choose the right size to avoid overloading your electrical system or damaging your appliances. Consider the largest appliance you’ll use and its startup wattage, and ensure your generator can handle it. Having some extra watts for additional power needs or unexpected usage.
Regular Appliances vs. RV Appliances: What’s the Difference?
Regular appliances are designed for home use, while RV appliances are specifically engineered for the mobile environment. RV appliances are usually more compact, lightweight, and energy-efficient to accommodate the unique challenges of RV living. Always check your appliances’ wattage requirements and size to ensure they’re compatible with your RV’s electrical system.
Electric Heat: Power Requirements and Generator Compatibility
Electric heat can be a great alternative to propane heating in an RV but it requires significant power. Electric heaters typically range between 750 and 1,500 watts, depending on their size and capacity. To use electric heat in your RV, you’ll need a generator with enough power output to accommodate the heater’s wattage requirements and any other appliances you plan to use simultaneously.
Frequently Asked Questions
Power Tools and Construction Sites: Can I Use My RV Generator?
Absolutely! RV generators can be a lifesaver when you need backup power at construction sites or for your power tools. Ensure your generator can handle your tools’ power output and startup wattage. Also, consider the fuel type to ensure you have a generator with excellent fuel efficiency for longer-duration use.
Indoor Power Generators: Are They Safe for RVs?
While indoor power generators are designed for use in homes during power outages, they can also be used in RVs. However, choosing a generator specifically designed for indoor use is essential, as these usually produce less harmful emissions and operate more quietly. Always follow the manufacturer’s safety guidelines and ensure proper generator ventilation.
30-Amp vs. 50-Amp RVs: What’s the Difference?
Q: How can I measure the actual power consumption of my appliances?
A: Use a watt meter to measure your appliances’ current draw and wattage usage. This will give you a more accurate picture of your power needs.
Q: Can I use solar generators instead of diesel or gas generators?
A: Yes, solar generators are a more eco-friendly and quiet option. However, they may not provide enough power for all your appliances, so it’s essential to understand their limitations.
Q: What’s the best type of generator for a 50-amp RV?
A: Look for a generator with an output of at least 6,000 watts, which should be enough to cover the electrical needs of a 50-amp RV. However, that may be more than you need, as you don’t need to run all the appliances simultaneously. It’s essential to check the power requirements of your specific appliances and choose a generator that can handle their combined wattage.
Q: Can I use a portable generator for my RV?
A: Portable generators can be an excellent choice for RV owners who need a flexible and easy-to-transport power source. Ensure the generator’s power output and fuel efficiency meet your needs.
Q: How do I calculate the amperage draw of my appliances?
A: To calculate the amperage draw, you can use Ohm’s Law: Amps = Watts / Volts. For example, if you have a 1,500-watt microwave oven running on a 120-volt electrical system, the amperage draw would be 12.5 amps (1,500 watts / 120 volts).
Q: What happens if I overload my electrical system?
A: Overloading your electrical system can lead to blown fuses, tripped breakers, or damage to your appliances and wiring. To avoid this, make sure you’re aware of the power consumption of your appliances and use a generator that can handle their combined wattage. Use a surge protector such as one of these:
