  • Natural gas portable generators provide a reliable power source for outdoor activities, emergencies, and remote work sites, offering a cleaner-burning alternative to traditional gasoline or diesel models. These generators can connect to a home’s natural gas line or use portable propane tanks, adding versatility for various situations. Key factors to consider when choosing one include power output, fuel efficiency, and noise level, ensuring the generator meets your specific needs—whether for essential appliances during outages or tools on a job site. Models with automatic voltage regulation are ideal for protecting sensitive electronics. Safety features like low-oil shutoff, overload protection, and carbon monoxide detectors are essential. We researched and tested several natural gas portable generators to identify the best options for different needs and budgets.

    Pros

    • Runs on gas, propane, or natural gas
    • Lightweight and easy to move
    • Quiet operation at 58 dBA

    Cons

    • Limited runtime on gasoline
    • May require additional setup for natural gas use
    • Higher price point than single-fuel options

    We recently tested the ERAYAK 4500W Tri-Fuel Generator and were impressed by its flexibility. The ability to switch between gas, propane, and natural gas gives users more options during emergencies or outdoor adventures. We found the transition between fuel types smooth, taking only seconds.

    At 54 pounds, this generator is lighter than many we’ve tried. We had no trouble moving it around our test site. The built-in handle made it easy to lift and carry. For camping trips or tailgating, this portability is a big plus.

    The generator runs quietly, which we liked. At quarter load, it’s about as loud as a normal conversation. This makes it good for camping or in neighborhoods with noise rules. We were able to run several appliances without disturbing our neighbors.

    We appreciate the inverter technology, which produces clean power for sensitive electronics. In our tests, it ran laptops, phones, and even a small TV without issues. The multiple outlets, including USB ports, let us power various devices at once.

    The fuel efficiency in ECO mode was decent, but we wish the gas tank was a bit bigger for longer runtime. Setting up for natural gas took some extra steps, so be ready for that if you plan to use it as a home backup.

    While pricier than some single-fuel models, we think the ERAYAK’s tri-fuel capability justifies the cost for those who want flexibility in their power source. It’s a solid pick for users who need a portable, quiet generator that can adapt to different fuel types.

    We think this GENMAX generator is a solid choice for those needing a versatile and powerful portable power solution.

    Pros

    • Dual fuel capability
    • Remote start feature
    • Parallel connection option

    Cons

    • Heavier than some models
    • Noisier than advertised
    • Pricier than basic generators

    We tested the GENMAX 9000W generator and found it to be a reliable workhorse. Its dual fuel system lets us switch between gas and propane, which came in handy during our camping trip. The remote start was a nice touch – we could power up from inside our RV on a chilly morning.

    The digital display is clear and easy to read. We liked being able to check voltage, frequency, and fuel levels at a glance. The CO detector adds peace of mind, automatically shutting off if carbon monoxide levels get too high.

    While GENMAX claims it’s “super quiet,” we found it to be louder than expected. It’s not ear-splitting, but you’ll definitely know it’s running. The generator is also on the heavy side at 281 pounds. Moving it around camp took some effort, even with the wheels.

    We appreciate the parallel capability. Linking two of these units could power a whole house in an emergency. For most users, though, one generator should be plenty. It handled our RV air conditioner with no problems.

    Build quality seems good overall. The steel frame feels sturdy, and the control panel is well-laid out. We had no issues starting or running the generator over several days of use.

    The control panel is a dream, with a mix of household and high-amperage outlets. We had no trouble hooking up our essentials and then some. The digital display kept us in the loop on run time and output, which was super helpful.

    Moving this generator is no joke – it’s a two-person job for sure. But once we got it in place, the sturdy frame and big wheels made small adjustments easy. The 17-gallon fuel tank gave us a solid 11 hours of run time at half load, perfect for those longer outages.

    We were impressed by the safety features too. The automatic low oil shutdown and CO sensor gave us peace of mind. While it’s not cheap, we think the WGen20000c is worth every penny for its reliable performance and robust build quality.

Buying Guide

When shopping for a natural gas portable generator, we recommend considering a few key factors:

Power Output

Look at the wattage rating. Choose a generator that can handle your power needs during outages or outdoor activities.

Check the run time on a full tank. More efficient models will operate longer without refueling.

Noise Level

Consider the decibel rating. Quieter generators (around 50-60 dB) are better for camping or residential use.

Portability

Assess the weight and wheel design. Lighter models with sturdy wheels are easier to move around.

Safety Features

We suggest prioritizing generators with:

  • Automatic low-oil shutoff
  • Circuit breaker protection
  • CO detection

Ease of Use

Look for:

  • Electric start
  • Clear control panel
  • Easy maintenance access

Warranty

A longer warranty period often indicates a higher quality product.

This table summarizes key specs to compare:

FeatureWhat to Look For
Power2000-7500 watts
Noise50-70 decibels
