YAMAHA EF3000iS, 2800 running Watts/3000 Starting Watts, Gas Powered Portable Inverter

Yamaha’s EF3000iS doesn’t often receive as much attention as the other generators on this list, but a great many customers have been extremely satisfied with its performance.

It’s a little less powerful than some of the previously reviewed generators, with a peak Wattage of 3000, and operating at a running Wattage of 2800.

Nonetheless, this generator should provide enough backup power for your RV using the L5-30R receptacle. It should also be sufficient for powering the less heavy-duty appliances in your home.

Once the generator is started using the pull-start system, the 3.4-gallon fuel tank can run for up to 18.6 hours on a ¼ load, giving you plenty of operating time between refuels.

Yamaha’s use of Smart Throttle technology allows the generator to automatically adjust its engine speed in accordance with the current load. This helps to make this generator more fuel-efficient.

Another benefit of the Smart Throttle technology is that it contributes to the EF3000iS’ noise reduction. This is also enhanced by its construction using sound-absorbing materials.

This generator has several power outlets for multiple purposes. These include 2 outlets at 120-volt, 20 amps, a single 120-volt, 30 amp outlet, and a DC outlet.

The power provided through this outlet is clean enough to make this generator safe for use with sensitive electronics.

Speaking of safety, the EF3000iS is equipped with several features to ensure the safety of its engine. Its Oil Watch Warning system, for example, shuts the generator off when oil levels get too low.

There are also indicator lights and a built-in fuel gauge, which allow you to monitor the status of operation and take action when needed.

The built-in wheels and handles of the EF3000iS make it easily portable despite its slightly cumbersome weight of 136 lbs.

Also included with this generator are the cables required for battery charging through the DC outlet.


  • 18.6-hour run time on ¼ load
  • Uses Smart Throttle technology
  • Multiple power outlets
  • Safe for sensitive electronics
  • Sound-absorbing construction
  • Oil Watch Warning system
  • Built-in wheels and handles
  • Battery charging cables included

Best 30 Amp Generators Buying Guide


Navigating the amperages and Wattages of generators can be a notoriously confusing task. Most manufacturers state the power of their generators in terms of Wattage, meaning that the amperage is often not included.

This can make it difficult to work out how many amps a generator puts out in the first place, let alone determine how it stands up to the competition.

The inclusion of a 30 amp RV outlet on a generator is a good indicator that the machine is capable of putting out 30 amps.

Alternatively, the calculation for converting Watts to amps is a very simple one, provided you have the operating voltage to hand. Simply divide the Wattage (ideally, the running Wattage, since this is the level the generator will operate at consistently) by the voltage.

So, for example, for a 4000-Watt generator that runs at 3700 Watts and is suitable for operation at 120 volts, divide 3700 by 120 to calculate the amperage. In this case, it would be 30.8.

If you don’t feel like doing these calculations yourself (we totally get it), there are online calculators that will do it for you. Just input the values and let the calculator do the rest.

Once you’ve determined the amperage of a given generator, you’ll be able to work out whether it’s powerful enough to meet your needs.


One of the main reasons customers often gravitate towards 30 amp generators rather than more heavy-duty builds is portability.

In general, the more powerful the generator, the bigger and heavier it is, so a 30 amp generator has the advantage of being much easier to transport and maneuver than heavier models.

As you may have noticed, the generators on our list vary in weight, ranging from about 95 lbs to closer to 150 lbs. Now, although these are quite lightweight in generator terms, most people still wouldn’t be thrilled about having to maneuver this kind of weight without any extra help.

Luckily, though, most of the generators on our list come with wheels and handles to assist you.


Before you purchase any generator, you should check whether the outlets provided on the said generator are suitable for the appliances or electronics you need to power.

Most 30 amp generators will provide 2 outlets for household use, which will usually be rated at 120 volts and 20 amps. The majority of the time, a 120-volt, 30 amp RV outlet will also be included. DC and USB ports are also common.

If you anticipate needing to charge your phone or laptop from your generator, you should also verify whether these outlets put out clean power that is suitable for sensitive electronics.


30 amp generators are most often used during power outages, or to power RVs on camping trips.

In both of these cases, ease-of-use is paramount. You don’t want to be struggling with your generator’s control panel in a power emergency, or on a trip where you’re supposed to be enjoying yourself.

The most important thing to prioritize in a generator when it comes to ease-of-use is an intuitive and easily accessible control panel. This will help you to get to grips with your generator as quickly as possible and make changing the settings a simple and efficient process.

A digital display is also helpful for easily monitoring the operation of your generator, including fuel levels and voltage, taking the guesswork out of the equation.

If you’re accustomed to pull-to-start generators (or lawnmowers, for that matter), then the startup process of your generator may not be an issue for you.

However, if you really want the easiest possible experience with your generator, you may wish to look exclusively for electric-start generators. This is because push-starting electric generators are typically easier and quicker to start.

Additional Features 

The additional features often included with 30 amp generators can also contribute substantially to a generator’s ease-of-use.

For example, an oil funnel can make the process of refueling much easier, less messy, and therefore, less wasteful.

The inclusion of DC charging cables also means that you can charge your batteries from your generator without having to make any separate purchases.

If your chosen generator requires some level of assembly on arrival or future maintenance, it can be helpful to have a toolset or wrench included with the purchase.

Additionally, most generators will also come with a user manual, which can really help you to familiarize yourself with the functions of your generator, especially if this is your first generator purchase.

Frequently Asked Questions

How many Watts is a 30 amp generator?

The Wattages of generators classified as ‘30 amp’ may vary.

However, on average, a 30 amp generator tends to run at roughly between 3000 and 4000 Watts.

What can I power with a 30 amp generator? 

A 30 amp generator should be able to power a 30 amp RV. In terms of household use, a 30 amp generator will not be sufficient to restore power to your entire home.

However, it should be able to help you in an emergency by powering a few of the bare essentials back up.

What these essentials are will vary according to the size and electrical setup of your home.

Generally speaking, though, a 30 amp generator should be able to power up either your refrigerator or oven and some smaller appliances, such as a portable heater and some lights.

If the generator features a DC outlet, it should also be capable of charging batteries should the need arise.
