Buying Guide

Buying the best generator is a difficult choice because you want a reliable unit that is durable runs throughout the night, and is eco-friendly. Most people use generators during major storms when there’s a power outage, while there are others who use it for mowing lawns and outdoor DIY projects. Other people use portable generators during camping and RV trips. Requirements change according to the situation, and one generator might be suitable for you but not for your friend’s house. And that’s why here’s an in-detail buying guide by our test panel to help you make the right choice.

Portable generator type: Inverter or conventional

Best Portable Generators – Take Power with You!There are two types of portable generators that you can choose from – inverter and conventional. Each type has its own set of pros and cons, so the decision lies entirely upon you. Portable inverter generators are more silent compared to conventional generators. They usually make less than 60 dB(A) of noise, which is quiet enough for you to sleep throughout the night. With conventional generators, you will have to bear more than 68 dB(A), which isn’t ideal if you have young kids and elderly who have trouble sleeping.

On the other hand, if you are short on budget, a conventional generator might be your choice. It is also heavier, so you can’t take it on camping trips. Conventional generators are less eco-friendly and not always the safest choice for powering delicate devices. However, big brands have come out with more eco-friendly and sensitive device-safe generators that you can use.

Some of the most efficient inverter generators on our list include Yamaha EF2000iSv2, Honda EU3000IS, Champion Power Equipment 100302, and WEN 56200i. If you plan to buy a conventional generator, our top picks are Westinghouse WGen7500DF, HONDA EB10000, and Generac XD5000E.

Power output

The amount of power output you want is a personal choice and depends where you live. For example, if you live in areas where there are regular power outages or somewhere rural, you will need at least 10,000 watts of power to run a median household. Westinghouse WGen and HONDA EB10000 are the two best 10,000W generators on the market.

On the other hand, if you want a generator to carry out small DIY activities or handle infrequent outages, settle for a 2,000 to 5,000W producing generator. Yamaha EF2000iSv2, Honda EU3000IS, DuroStar DS4000S, and Goal Zero Yeti 1400 WiFi are good choices for such users.

Fuel: gasoline, propane, or both

Most models mentioned on our list run on gasoline since they are portable generators. Gasoline is easily available, so you won’t have any problem finding fuel during emergencies. The fuel also makes the generator last longer.

However, if you want to have the option between fuels, you can go for Westinghouse WGen7500DF. It runs on gasoline and propane. You can switch between fuel effortlessly. Propane will have a lower runtime compared to gasoline, so don’t keep it your first choice. If you want a propane generator, Sportsman GEN4000LP is the best choice. Unfortunately, it consumes a lot of fuel like any other propane generator, so it isn’t the best choice environmentally.

Fuel tank capacity and runtime

Best Portable Generators – Take Power with You!An ideal generator should run throughout the night, so you don’t have to get up during the night to refill the tank. In our article, we have calculated runtime at 50 or 25 percent load, assuming that the tank is fully loaded. Yamaha EF2000iSv2 is a small 2,000-watt portable generator that runs for 10.5 hours at 25 percent load. It can keep your air conditioner or heater running throughout the night so you can stay as comfortable as possible.

Another good generator is the Honda EU3000IS that runs for 20 hours at 25 percent load. Champion Power Equipment 100302 is one of the most efficient with a 17 hours runtime at 25 percent load. Our favorite from the list is Pulsar PG4000iSR, which offers 15 hours of runtime at 50 percent load, making it one of the most efficient generators in the market.

Safety features

Top safety features that a generator must have include low oil shut off to prevent the engine from overheating, CARB compliance, and EPA approved. Only if the generator has CARB compliance, you can use it in national parks and California. Both indicators specify that the generator produces eco-friendly energy. Another indicator of a safe generator is the noise it produces. It should be less than 60 dB(A) from 10 feet away. If it is too loud, the generator can cause noise pollution, and it won’t only disturb you but also those around you.

Ease of use

There are three types of start options available – electric, recoil, and remote. Pulsar PG4000iSR offers all three types, which is the most convenient option because if one is broken, you can use the other option. Avoid buying generators with recoil start because you have to pull a cord to start the machine, and it can hurt your arm and back muscles. Generac XD5000E is another good option as it comes with two types of start, including electric and recoil. You will also like the Honda EU3000IS, which comes with two-start options as well.

The generator you pick should have an LCD, preferably, to check the available fuel in the tank, oil levels, and the number of watts consumed by different appliances. It should also offer an easy way to refill the tank and remove used oil.

Noise level

Generators make a lot of noise, but there are some that come with a muffler to reduce it. Inverter generators are quieter than conventional generators, but they are also more expensive. If you want to sleep peacefully throughout the night, inverter generators are a better choice. Yamaha EF2000iSv2 is one of the quietest in the market at 51.5 dB(A). Other low noise-producing inverter generators include Generac GP2200i and Honda EU3000iS. If you want to buy a conventional generator because of budget constraints, purchase a muffler to reduce the noise.

Goal Zero Yeti 1400 WiFi is also a good choice but only for infrequent users. It is a lithium power station that produces peak wattage of 3,000 watts and rated wattage of 1,500 watts. It doesn’t produce any noise or harmful fumes and is best for outdoor use.

Dimensions and weight

Best Portable Generators – Take Power with You!Since we are talking about portable generators in this article, the ideal weight shouldn’t be more than 50 pounds. You will be carrying it with you on road trips and camping, so you need a generator that’s lightweight. At 44.1 lbs, Yamaha EF2000iSv2 is the lightest generator on our list. Despite the weight, you will need another person to help you carry it.

If you don’t plan to take the generator on camping trips and want to use them around your house, Goal Zero Yeti 1400 WiFi is a good choice. It weighs 43.7 lbs and has handles that make it convenient to carry. Bigger generators like Westinghouse WGen7500DF and Honda EU3000IS weigh over 130 pounds and meant more for stationary use. You can still drag it on their wheels to nearby locations, but they aren’t ideal for camping trips. Alternately, you can mount them in your RV for long-term use because of them have RV-ready outlets and are fuel efficient.

Warranty and customer service

The best way to know if the generator’s a right fit for you or not is by getting the warranty terms. Ideally, you should receive three years of residential warranty and one year of commercial warranty. Longer the warranty, the more durable the generator. Honda EU3000IS is the best portable 3,000-watt generator because it offers three years of residential and commercial warranty each. Champion Power Equipment 100302 comes with only three years of residential warranty. Another great option is the DuroStar DS4000S, which offers three years of residential warranty and one year of commercial warranty.

The kind of customer service you receive inside warranty and out of warranty matters as well. Here are a few questions you need to ask before finalizing the generator:

  1. Does the manufacturer have several service stations throughout the country?
  2. Is the customer care department apartment throughout the day?
  3. Does the manufacturer offer at-location repair services?
  4. What is the manufacturer’s policy on guarantees?
  5. Does the manufacturer or dealer offer adequate training to their employees to repair the generators?

Portable generator prices

Portable generator cost $300 upwards depending on the peak wattage and runtime. The cost will depend on the brand, fuel tank capacity, and a number of outlets. Price should be your last concern because buying an affordable model can compromise on your safety, customer service, and fuel efficiency. If you live in California, you will need to buy a CARB compliant generator, which is going to be more expensive than a non-CARB compliant model.

Like this, there are many other factors that influence the cost. The generator should produce a high surge power to start big appliances like refrigerators and air conditioners and maintain a comparable running wattage power.

Tips

Best Portable Generators – Take Power with You!You need a well-functioning generator to survive through hurricanes, cyclones, and rainstorms and run multiple appliances, including air conditioners, refrigerators, heaters, and delicate devices like computers, mobile phones, and laptops.

Here are six tips that will come in handy while buying a portable generator:

  1. Determine your power needs before buying a generator

The very first thing that you need to identify is your requirement for buying the generator. Someone might need it for camping or RV use; others might need as a backup during power outages. For camping and RV use, you will need 4,500 to 7,500-watt generators. For backup, you need a generator that produces at least 9,500 to 12,000 watts. Bigger generators are difficult to move, so if you need a generator for both purposes, you will need two separate models.

  1. Add watt consumption of the appliances you want to run on the generator

An average-sized refrigerator requires 700–1,200 watts of power to run for an hour, while a microwave needs 600–1,200 watts. If you want to run three appliances, two big and one small, you have to multiply the number of watts by 1.5. For example, if the calculated watts comes to 2,500 watts, you will need a generator that produces 3,000 surge watts.

  1. Find a generator with a minimum of 10 hours runtime

Always look for a portable generator that runs for 10 hours at 25 percent load, so it can run throughout the night without needing a refill. If you plan to use it commercially, you will need something that doesn’t need repetitive refills because that’s a waste of time and labor.

  1. The generator needs to have at least four outlets

The generator you pick should have at least four outlets, two for big appliances and small devices each. It should have RV ready outlets, so you need a transfer switch for using it in your motorhome. If you want to power more appliances at the same time, find a generator with five or more outlets.

  1. Ease of transportation

Whether you are renovating a fixer-upper or go on regular camping trips, you will need a lightweight, portable generator with never-flat wheels and a handle to drag it. A good portable generator should never weigh more than 45–50 pounds.

  1. Purchase a generator with electric start

Modern generators come with electric start, which starts the generator using a simple push button. Don’t buy a generator with only recoil start because it can hurt your back and arm muscles. Some models come with remote control, which is more expensive.

Precautions to take while using a portable generator

Best Portable Generators – Take Power with You!A portable generator is made to save your life during power outages, so make sure to use it with care and precaution to avoid any mishaps. Here are some precautions you need to take while using one:

  1. Regular manual maintenance is important

Change the spark plugs periodically and clean the screen on the spark arrestor. Even when not in use, ensure the oil tank has more than the minimum amount of oil. Change the oil after running the generator for a number of hours as specified by the brand. Also, change the air filter periodically as mentioned by the manufacturer.

  1. Test the generator as soon as you buy it

Don’t wait until the emergency situation to arrive to test the generator. As soon as you receive it, test the model. Always use heavy-duty extension cords with 12-gauge wire for safe conduction.

  1. Run it frequently for a short time to keep it functioning

A generator that hasn’t been used for a long time can’t be trusted during power outages and that’s why you need to start it for a few times every two weeks.

  1. Never connect it to your house’s electric service panel

A generator is designed to work on limited power using electric cords. If you connect it to your house’s electric service panel, the generator can fry the sensitive devices. Call a professional to connect the generator with the main service panel of your house. Whenever the power is out, your house appliances will run automatically on the generator.

FAQ

The size of your largest or biggest appliance determines the size of the generator. If your RV has an air conditioner that will be your deciding factor. The appliances consume anywhere between 700 to 1,200 watts of power; your RV will need 3,000-watt portable generator.

Gasoline is definitely more efficient than liquid propane. For example, Westinghouse WGen7500DF is a dual generator that runs on both gas and liquid propane. If you use gasoline, the generators run for 16 hours at 25 percent load. On propane, it runs for 11 hours at 25 percent load. You can’t add liquid propane to the fuel tank, which means you will have to add an external tank. Also, propane is more expensive and difficult to find compared to gasoline, so it is best to stick to gas generators for fuel efficiency and affordability. However, keep in mind that propane is ecologically-friendlier and easier to store.

Yes, your generator can run nonstop for 24 hours. However, you will have to refill the fuel tank and check oil levels every six to eight hours. You must also make sure that you don’t overfill the oil tank because it will get all greasy and only create a mess to clean up later. If you live in an area where you suffer frequent power outages, you will have to run maintenance checks every seven days.

Yes, you can use a portable generator to power your house during emergencies. It might not be the most efficient choice because you can’t too many devices on the generator because of limited capacity, but you can keep your family members comfortable by running the air conditioner and cooking some warm food.

Our Verdict

After reviewing some of the best portable generators available in the market, we have three top choices for you to purchase. Our top favorite is Yamaha EF2000iSv2, which is a 2,000-watt generator with three years of limited warranty. It is a highly efficient model because it runs for 10.5 hours at 25 percent load on a small tank capacity of 1.1 gallons. The generator’s easy to carry around since it weighs only 44.1 pounds and has a handle to hold it firmly. Also, it is one of the quietest models in the market and makes less than 5.15 dB(A) of noise so that you can sleep peacefully throughout the night.

This brings us to our second pick, which is the EU3000IS by Honda. It is an inverter generator like the first model by Yamaha and produces 3,000 watts of surge wattage and 2,800 watts of running wattage. It is fitted with a strong and durable engine, 196cc Honda GX200, which makes the generator run for 20 hours at 25 percent. With two start options and three years of residential and commercial warranty, EU3000IS is the best for home use. The only downside of this model is its weight, which is 131 pounds. It may be difficult to carry it around, but you can attach wheels and make it more convenient to transport, and it has handles on both sides to be carries by two people.

Our next favorite is the Goal Zero Yeti 1400 WiFi, which is not a propane or gas generator but a lithium power station. It isn’t the most efficient because there’s a huge difference of 1,500 watts between a surge and running wattage, but it is eco-friendly, doesn’t make any noise, and doesn’t produce any fumes. The model’s a perfect choice for RV users or outdoor use because it has six outlets that are RV-ready. It produces clean energy that can power sensitive devices without causing any damage. Weighing at 43.7 ponds, it is a lightweight model that comes with a one-year limited warranty from the manufacturer.
