Best 3000 Watt Inverter Generators of 2022

Last Updated on February 10, 2022

For people you love to get away camping in their RV, you know the importance of a high-quality generator for making your trip more comfortable and enjoyable. However, many generators lack the power or fuel efficiency to run your appliances, air conditioning, and lights without putting a significant drain on the motor.

A 3000 watt inverter generator is the best way to enjoy the modern conveniences of home while out in the wilderness. Unlike other high-powered generators, 3000 watt models are designed to be compact and lightweight for better portability. The inverter technology allows the generator to moderate its output depending on your needs rather than running continuously on full power, making it a quieter, more eco-friendly way to power your camping trip.

The Champion 3400 Watt Dual Fuel generator excels in every area of performance and finds the perfect balance of versatility and convenience. Whisper quiet with a long-lasting 14.5-hour continuous operation, as well as a reliable, efficient dual fuel system – there is simply no better 3000 watt generator on the market.

If you are heading out on a family camping trip, Champion has developed the ideal RV-ready solution for your energy needs. Don’t wait, buy the Champion 3400 Watt Dual Fuel generator.

5 Best 3000-Watt Inverter Generator Reviews

1. Champion 3400-Watt 3000 Watt Inverter Generator – Best Overall

Dual fuel generators offer better flexibility and reliability than generators running on only gas or propane. The Champion 3400 Watt Dual Fuel Inverter generator takes dual fuel technology to the next level by providing users with additional safety features and improved fuel efficiency.

The unit features an 0.6-quart oil tank and a low-oil sensor to ensure the motor runs smoothly, while the 1.6-gallon gas tank provides up to 7.5 hours of use at a quarter load or 14.5 hours when used with propane. While this isn’t the biggest tank on the market, it offers the right balance between lightweight portability and long-lasting operation.

The Champion 3400 Watt Dual Fuel generator has an RV-ready set up, so there is no need to purchase additional adaptors. It also has a parallel compatible outlet to hook up to another Champion generator for added power.

2. Champion 75531i 3100-Watt Inverter Generator – Best for the Money

For an affordable generator that can still power all your necessary RV appliances, you can’t beat the Champion 75531i 3100 Watt Inverter. The 171cc engine produces 2800 running watts and 3100 surge watts, and the 1.6-gallon unleaded gasoline tank will provide you with up to 8 hours of energy at a quarter-load. It also features an Economy Control Switch to reduce the engine capacity when not in use and minimize wear and tear.

Although relatively lightweight at 85.5 lbs., this inverter is still too heavy to manually carry around, and its lack of telescopic handle makes it tricky to maneuver. Champion has attempted to correct this drawback by installing tough tires to improve portability, but with an engine that is substantially bigger than many other inverters, this is best used for powering your RV rather than lugging around a worksite.

Another standout feature is the convenient remote start key fob, so you won’t need to leave the campfire conversation to restart your generator.

  • 1.6-gallon unleaded gas tank

  • 24.4” x 18.3” x 14.3” housing

This EPA- and CARB-compliant generator is Honda’s quietest model yet, emitting only 50dBA at a quarter-load – well below the noise level of general conversation – achieved due to the noise reduction casing and the Honda Eco-throttle.

What truly sets the EU3000IS1A apart from the rest is the astonishing 20-hour run time on a 3.4-gallon tank. The state-of-the-art inverter technology means cleaner, more efficient power output from the 196cc gas engine, making it ideal for running a huge variety of sensitive electronics without worrying about overload.
