What is the Best Generator to Buy?

Generators can be looked at in 2 ways – stationary units (or standby generators) and portable generators. 

Stationary generators cost more and should inquire professional help for installation. and should be installed by a professional, and includes the labor for installation.

Helpful things to know regarding the purchase of stationary generators:

  1. Confirm with city municipal permits for things such as: location,  noise ordinance
  2. Stationary units automatically turn on when power cuts out. A proper unit also runs their own self-diagnosis for maintenance requirements. The advanced machines enable text or email notifications.  
  3. Power: Units range from roughly 5000 to 20,000 watts and can up to $10,000 or more in price.

For Stationary Whole House Generators, we recommend Generac 6729 Guardian Series

Portable generators are lighter, a lot less costly, and run either on gas or propane.

Helpful things to know regarding the purchase of the best portable generator

  1. Stabilizers are required for gas storage.
  2. Portability of these units gives you flexibility to bring your unit where you need power.
  3. However, we recommended that be at least 6 feet away from your doors, homes, and windows, not in an enclosed space.
  4. Some portable generators have an electric start. We recommend checking with manufacturers to make sure your unit comes with a battery. Otherwise, you would need to purchase a battery separately. Typically their wattage is between 3000 to 8500, and up to $1000.
  5. Portable generators are more cost effective units that provide power that is both mobile and portable. 

The best portable generator is the DuroStar DS4000S. We like it because it is powerful for it's size. Categorically, we consider it a mid-tier generator that delivers up to 4000 watt output and a 7.0 amp air cooled OHV engine plus a low oil shutoff. This has a run time of eight hours at half-load and includes two 120 volt outlets and one 120 volts 30 amp outlet, plus it is easy to start with the EZ-Pull as a start feature. In totality, we view the DuroStar as a great value buy and a best power generator for the money. 

How to Calculate Home Generator Wattage

To find out what size of generator you need to buy, you need to calculate your wattage.

This is something of a pain, but it is not actually all that complicated. It is a matter of going around your house and figuring out which appliances you will need to power. You then need to find out their wattage's and add them all up.

Many appliances actually list their wattage's somewhere on the device; failing that, if you have kept your product manuals, you should be able to find the exact wattage's in there. If you know the appliance number, you may be able to look up the information online.

If you cannot find the exact wattage's for your appliances, or you want to take a shortcut, here are some common values:

Shopping for best generators based on wattage?

How much does it cost to install a whole house generator?

In addition to the cost of your generator, the total cost including installation ranges somewhere between  $500 to $3000.  Portable units are mobile so they do not require professional installation assistance.

In the section below, we break down the actual cost of your generator in greater detail based on your home's specifications. 

What size generator do I need?

When determining your home power needs, we suggest starting with the following questions to help figure out the amount of wattage you need to get the job done: 

  1. Are you currently using well water or city? 
    Well pumps need a 230+ volt generator (3800 watts or more).
  2. Is your heating system heat pump, electric or gas or oil forced air?
    For oil forced or gas powered air systems, you can use a very small generator. About 2500 watts is the starting  point.  As a rule of thumb, the larger the furnace system the more power you are going to need.
    Electric heating systems need a minimum of 15,000 watts or more to work. Therefore, a portable generator won't cut it. 
  3. Is your hot water systems powered by gas, oil fired or electric?
    As mentioned above, oil fired heaters or gas require the least  – as little as 2500 watts.
    Electric heaters require more energy - at least 4500 watts.

If your house uses a smaller furnace and runs city water then 3000-5000 watts should cover your needs. If you have a well pump or a larger furnace, you are going need more power-something like 5000-7000 watt generator.

Here's a video on How to Calculate Watts.

I have tried to give higher-end values above, but keep in mind a couple of key points:

  • There is a range for every type of device, not just one possible value. Your appliances may use a higher or lower wattage than what you see above.
  • There is a higher start-up wattage when you power up a device. The wattage then drops for the duration of time the item is in use.

What are standard Home Generator Sizes?

Once you have an estimate of the total wattage you need to power all the appliances you plan to use in an emergency, you will know what generator size you need.

  • Small: Generally provides anywhere from 2,000-7,000 watts. These portable camping generators are also known as “inverter generators.” The price for these can range quite a bit; the more watts, the more you will pay. (Here is our article on Best Small Generators for Home Use)
  • Medium: Provides 1,000-5,000 watts. This is best for powering a few key appliances only.
  • Large: Provides 6,000-8,000 watts. Use a large generator to power a couple of rooms or a few more key appliances.
  • X-Large: Provides 10,000-25,000 watts. Power your entire home.

Remember, you will not be using all of your devices simultaneously! So even if you calculate a sizable combined total, that does not mean you need a generator that can handle that full load. Ask yourself which appliances you are likely to use simultaneously, and add up the load for all those devices. Remember there are also appliances which really are not that important to use in an emergency; try to stick with the essentials.

As you have probably noticed, there are a few appliances which are almost impossible to power reliably using a generator. One power-guzzling electric furnace may suck up all your generator power. So this is also a great time to think about replacing power-hogging devices with appliances which use a lower wattage (this will also save you a ton of money over time).

Generally speaking, the larger your generator is, the more it will cost. Medium generators usually start out around $400, while large generators start at around $800. Expect to pay a minimum of approximately $2,000 for an x-large generator.

Home Standby Generators, Portable generators, or Inverter generators?

Generators can be grouped into three main categories: standby, portable or inverter.

Best Home Standby Generator Reviews

  • This is a fully enclosed unit intended for permanent installation. Like all other generators, it should be installed outdoors.
  • You will connect the standby generator directly to your electrical system. You can use it to power some or all of your appliances.
  • Standby generators are usually powered either by natural gas or liquid propane.
  • Models may be liquid-cooled or air-cooled. The liquid-cooled models provide more power.
  • These units provide anywhere from 5,000-25,000 watts of power.
  • Price may range anywhere from around $2,000-$20,000.
  • Professional installation is usually required, so setting up a standby generator will cost you extra. You may also need to get a permit.
  • May include extra features such as the ability to kick on automatically during a power outage.

Best Portable Generators

*Here's our guide to Best Portable Generator 

  • These units are not fully enclosed, and generally are smaller than standby generators. They are designed as back-up power sources, but may also be good for portable or recreational use. The smaller models can be picked up and carried. The larger ones need to be wheeled around.
  • A portable generator can hook up to a home outlet or you can plug power appliances into it directly.
  • The majority of portable generators require gasoline as a power source, though you may find some models which accept liquid propane.
  • These units must be installed at least 15 feet away from your home. While they must be kept in the open, they do require a cover or tent of some sort to protect them from the weather.
  • Electric starting is available for some models, but you will likely have to buy the batteries separately.
  • These generators provide anywhere from 3,000-10,000 watts.
  • Price typically ranges anywhere from $400 to $2,000.

Best Inverter Generators Reviews

*Here's our guide to Best Inverter Generators

  • These generators are designed to be compact, lightweight, and easily transportable. They are ideal for camping or other portable use.
  • If you are looking for a generator which will run quietly, an inverter generator is your best bet (this may be important if you will use it camping).
  • An inverter generator is a good choice for running sensitive electronics.
  • You can hook up an inverter generator to a vehicle.
  • These generators may provide 2,000-7,000 watts.
  • Price typically ranges from around $300-$3,000.

You may find that a single generator is all you need, or you may discover that a couple of different generators are useful for various applications. I ended up buying a standby generator for my home, but I also have a powerful inverter generator which usually stays at my retreat to essential power devices. When we head out on camping trips, we can take it with us to our campsites and enjoy some of the comforts of home entirely off the grid.

Power Options for Whole House Generators

The most common power options you will encounter for generators include:

  • Gasoline
  • Diesel
  • Propane
  • Natural gas

* Here's our guide to Best Portable Propane Generators

You probably want to pick a fuel gas option based on what is most convenient to you with your current setup. If for example you already have an oil burner and a large storage tank in your home, diesel might be a good choice. It is safer than gasoline, though it does have its downsides. As with gas, you need to treat it with preservatives. You will burn through diesel quickly—which is true of gasoline too.

As I mentioned already, portable generators usually are powered by gasoline. With the larger standby models, you may have your choice between natural gas, diesel or propane. If you can opt for propane, it is an excellent choice since it can be stored safely and is unlikely to degrade even over a long time period. That means you do not need to treat it to maintain it.

There are a few solar generators on the market right now as well. Most of them can only provide you with a relatively low wattage (I have seen up to 4,000 watts at the high end), and the price tag can be kind of hefty. But apparently, a solar generator can save you money over the long run, and maybe a good option for your retreat in case of a real long-term emergency.

Best Generator for Home - Important Features

There are numerous extra features which some generators may be equipped with. Here are a few you can look for:

  • Automatic start. This is a feature which is common in standby generators. If the power grid goes down, the standby generator turns on automatically.
  • Electric start. If you do not want to pull-start your generator every time, you may find electric start to be a useful feature. Just know that you typically have to buy the battery yourself, so tack on an extra $50 or so.
  • Wheels. While your larger portable generator probably already includes a wheel frame, you will be lucky if the wheels are included as well. Oftentimes you are forced to purchase these separately, so make sure you know whether this is the case or not. If you do need to buy them separately, they will likely cost you around $150.
  • Fuel options. Many models only offer you one fuel choice, but there are some generators which may allow you to choose between a couple of power options (e.g. propane or natural gas). You may also have the option to augment your fuel choices with a conversion kit.
  • Fuel gauge. How much fuel do you have left? You never want to risk running out right before an emergency. If your generator includes a fuel gauge, you will never need to worry about this; you will always know exactly when you are getting low.
  • Clean power. Inverter generators not only can provide you with quieter performance, but they also can provide you with cleaner power. This is why they are ideal for your sensitive electronics.
  • Removable console. This is a useful feature which prevents you from having to run a lot of extra extension cords outside.
  • Extra outlets. Some generators include only one outlet; others provide you with multiple outlets. This allows you to spread the load, which may in turn provide you with a more efficient use of your wattage.

The Importance of a Generator Transfer Switch

If you are shopping for a standby generator, you must get a transfer switch. This is something which you have to install yourself.

What is it? It is a device which cuts off the power line leading from the grid to your home. This allows the generator to switch on and start providing power instead safely.

Why is this so essential? Without a transfer switch, it is not safe to operate your stationary or portable generator. You can end up overloading your circuits, which may destroy your appliances and even damage the generator itself. You also can create problems throughout the grid. If utility workers are trying to repair it, you could even harm them.

If you have the electrical know-how, you may be able to install the transfer switch yourself, but if you do not, you should call in a professional to handle the job. It will run you around $500-$900 (that is the cost with labor included).

If you need a cheaper workaround, you can consider an interlock device, which will cost you around $50-$150. This device can prevent energy spikes, but you need to work through a sequence of steps to use it manually.

Installing Your New Home Generator

The exact steps involved in installing your new generator are going to depend on the type of generator you buy and your particular electrical setup. 

If you notice, it is not easy to install a portable generator if you are not already skilled in electrical engineering. Many people opt for professional installation. And as I stated earlier, with a standby generator, professional installation may be required depending on where you live.

Safety Precautions for Installing and Using Your Home Generator

The most important thing (other than picking the right generator for your needs) is to make sure that you stay safe once you get around to installing and operating it. Here are some quick tips to ensure that you are staying safe:

  • Read the manual and instructions front-to-back before you start setting up your generator. If you require a professional’s assistance, get it.
  • Always run your generator outdoors in an open area. Enclosed spaces do not provide adequate ventilation. The generator needs a minimum of five feet of clear space on every side as well. 15 feet is even better.
  • Keep your generator far away from open flames, pilot lights, and so on.
  • If you purchase a portable generator (as opposed to a standby model), do not ever wire it directly into your home’s electrical system. Use an outlet.
  • Make sure the generator is on a level surface.
  • Ensure that your generator is properly grounded.
  • Do not expose your generator to dirt, moisture or vapor.
  • Know that fuel expands. If you overfill your tank, you are going to have a serious problem.
  • Never exceed the load capacity of your generator. If you need more power, you need a more powerful generator.

The Best Home Generator Buying Guide Reviews

Now that you know all about the different types of generators and have a better idea what you need to shop for, I want to tell you about some of the best generators on the market right now.

Remember, you should be making your buying decision primarily based off the type of generator you need. Price should be a secondary consideration. If you really need a standby generator, you are going to have to accept that you will be paying a lot more for it than you would for a portable or inverter generator.

But that does not make your budget irrelevant either. You will notice while shopping that portable and inverter generators are a lot more popular and widely reviewed. This is in part because they are more affordable—but it is also because most people do not really need or want a dedicated, permanent generator. They realize they can get away with paying less for a portable generator and still take care of most of their needs, so that is what they do.

I had a big budget, and I live in an area with intense winters and regular outages—so a standby generator was the best choice for my home. If you have a smaller budget, ask yourself if a portable generator will be sufficient for your needs. If it is, you can save money. If not, I recommend biting the bullet for a standby. Just make sure you know what you are doing before you buy one; otherwise your generator may fail on you. You will see what I am talking about as you read the reviews below.

Best Standby Home Generator Under $20,000

Generac Guardian Series QT04524ANSX

Rating: 2.5 / 5.0

Need more than 22,000 watts? The Generac Guardian Series QT04524ANSX is a generator available in a range of different wattages:

  • 8,000 watts
  • 11,000 watts
  • 16,000 watts
  • 22,000 watts
  • 45,000 watts

If you need 22,000 watts or less, you can buy this generator for under $5,000, but if you are shopping for 45,000 watts, you will pay $15,000+.

Key Features:

  • Up to 45 kW
  • Liquid-cooled engine
  • Runs on liquid propane or clean-burning natural gas
  • Quiet Test available
  • RhinoCoat paint finish provides protection from weather
  • Steel casing
  • UL-listed

What This Generator is Best For:

Not a lot of customers need a generator this expensive, but it would make sense if you live in a very large home or if you need backup power for a commercial or public structure. Note that if you live in California, you cannot purchase this generator as it is non-CARB compliant.

Why Choose the Generac Guardian Series QT04524ANSX?

This is a heavy-duty generator with solid steel construction and a durable paint finish, which makes it an ideal all-weather solution. It can power your home or commercial structure continuously for weeks if need be, and is rugged enough that it should run well for years before you need to replace it. The engine is actually automotive-grade, which means that it could power a 4WD truck for hundreds of thousands of miles without failure. As you can imagine, it should last much longer sitting outside your home or office.

Pros and Cons

Customers who have purchased the Generac Guardian Series QT04524ANSX report that its durability matched up to their expectations and that the model runs smoothly and reliably. It provides enough power that you may be able to run multiple AC units plus other devices simultaneously.

You will notice while researching this generator that not all the reviews are positive. Most of these poor reviews come down to either 1-poor installation, or 2-poor maintenance. Like the Generac 6551 Guardian Series, the QT04524ANSX requires an ongoing commitment to maintenance if you want to get the most from it.

Best Standby Home Generator Under $15,000

Generac Protector Series Diesel Standby Generator

At present there are no reviews or ratings on this generator, but Generac is one of the gold standards for standbys. Why is it hard to find reviews for standby generators like this one? The reason is simple; most residential customers need portable or inverter generators, not standby generators—so you just will not find as much customer feedback. Regardless, with its excellent features, the Generac Protector Series 20 kW standby generator makes a great purchase in the $12,000-$13,000 range.

Key Features:

  • 20 kW
  • Includes Code Ready, a set of preconfigured options which are popular for operation.
  • Code-driven accessories included.
  • If there is a fuel leak, an alarm sounds and the generator shuts off automatically. There is a secondary tank basin to contain any leaks.
  • Inspect the generator’s status any time through an external viewing window.
  • External vent and fill.
  • UL/CUL 142-listed tank featuring double walls.

What This Generator is Best For:

As with other standby generators, the Generac Protector Series diesel standby generator is ideal for commercial settings, public buildings, or large homes. 20 kW is sufficient to power most household devices simultaneously. That includes central AC or heat.

Why Choose the Generac Protector Series Diesel Standby?

Generac is a trusted brand in the world of standby generators. There are not a lot of standby generators with ample customer reviews, so you need to shop mostly by features and brand reputation. The Generac Protector Series Diesel Standby offers you both.

Pros and Cons

The Generac Protector Series Diesel Standby includes excellent safety features such as the extra basin to contain leaks and the automatic alert and shutoff should a leak be detected. Other conveniences include a built-in hour meter, quiet weekly Quick-Test™, and removable doors which offer you quick access should you need to refuel or service the appliance. This device should run for years if you take care of it properly.

One drawback is that you do need to purchase the transfer switch separately. This is par the course with many standby generators however, so it is an added expense you should be prepared for. The only other drawback is that there is not a lot of customer feedback at this point.

Still, feedback on other Generac generators does give you a good idea what you can expect with this purchase. Reviews tell the same story again and again: Generac generators like the Protector Series run great—but you need to know what you are doing and be ready to make an ongoing commitment to maintenance.

Best Standby Home Generator Under $10,000

Generac 6551 Guardian Series

Rating: 4.0 / 5.0

While browsing the internet, you will discover that there are only a few standby generators which are really popular. One of the most noteworthy is the Generac 6551 Guardian Series. This generator has more than 30 customer reviews and an average rating of 4 out of 5 stars. The price range for the 22-kilowatt model is $4,000-$6,000. There are also a couple of other models with lower wattages (20 kilowatt or 8 kilowatt).

Key Features:

  • 22, 20, or 8 kilowatts (depending which option you choose when you buy)
  • Air-cooled
  • Fully enclosed in aluminum for weather protection
  • Natural gas or liquid propane-powered
  • Automatic start (no manual start)
  • Hands-free operation
  • True Power Technology protects sensitive electronics
  • EPA, CUL, and UL-compliant
  • 5-year limited warranty direct from the manufacturer
  • Composite mounting pad means you do not need a poured concrete base
  • Self-test runs only 12 minutes (there are also models in this series with a 5-minute self-test; pick the 12-minute option)
  • Automatic transfer switch required
  • Customer service is available 24/7/365

What This Generator is Best For:

Purchase the Generac 6551 Guardian Series if you are looking for a generator you can connect directly to your electrical system to provide your home or retreat with permanent backup power. If you take a look at the wattage chart which I shared with you previously, you will see that 22 kilowatts (22,000 watts) is sufficient to power numerous home devices simultaneously, and is even enough to operate central AC or an electric furnace. This makes it a great choice if you live in a part of the world which is subject to major temperature swings.

Why Choose the Generac 6551 Guardian Series?

The Generac 6551 Guardian Series is a relatively known quantity in a market where it is hard to find customer reviews. Because standby generators are expensive and more challenging to install than portable or inverter generators, there simply are not as many people who purchase them. It is always good to know what you are getting, and you have a lot more information to support your purchase with the 6551 Guardian Series.

Generac 6551 Guardian Series Video Review

Pros and Cons

The 6551 Guardian Series has some excellent features, like the option to choose natural gas or liquid propane. The Generac OHVI engine is powerful enough that you can run this generator for weeks if necessary continuously. Ease of use is another great advantage; the two-line LCD text display is clear and can be displayed in multiple languages. The backlit buttons are color-coded. You can even connect the generator to your smartphone to check on its status.

But this model does have some drawbacks too. A number of customers have mentioned there are some problems with the exercise mode/self-test. It seems in particular the 5-minute test is not sufficient to burn moisture off the oil. So it is best to opt for the 12-minute test, and to skip the “Quiet Test” feature. This should extend the life of the generator and prevent failures.

For that matter, it is important to know when you buy a generator like this that regular, ongoing maintenance is essential to its continuing operation. You cannot buy it, install it, and forget about it and expect top-shelf performance. This is the mistake that many purchasers make.

So Generac 6551 Guardian Series looks to be a strong purchase choice, if you are willing to put in the time and effort to keep up its maintenance.

Best Standby Home Generator Under $5,000

Briggs & Stratton 40445 8000-watt Home Standby Generator System

You are not going to find a lot of standby generators for sale under $5,000; standby generators are generally going to be significantly more expensive than portable or inverter models since they are built as permanent solutions which offer you a higher wattage. One exception is the Briggs & Stratton 40445. This 8,000 watt generator sells for $1,500-$3,000.

Key Features:

  • 8000 watts.
  • Automatic quick response powers up the generator within seconds of a power outage. This system can also automatically deactivate the system should the grid come back online.
  • The transfer switch is included at no added cost.
  • 3-year limited manufacturer warranty on parts and labor
  • Meets NFPA 37 standard
  • You can place it as close as 18” from your home
  • User-friendly control panel

What This Generator is Best For:

In a way, the Generac Briggs & Stratton 40445 is an “in between” option if you want something more permanent than a portable generator but do not need or want to go all-out and spend a ton of money on something that can power your entire household. Use the Generac Briggs & Stratton 40445 to power your lights and essentials in case of a power outage. This would be a great choice for a residence or small business.

Why Choose the Briggs & Stratton 40445?

There are very few options for standby generators in the under-$5,000 price range. The Generac Briggs & Stratton 40445 has a number of customer reviews and ratings, so you can learn more about it than most models. It is designed for “easy” installation and use. Being as it is a standby model, you will still need professional help, but getting started is relatively simple.

Pros and Cons

The fact that the transfer switch is included is a big plus—usually you have to buy this separately. So that is one less cost to worry about, and one less part to hunt down. It is also hard to beat the Generac Briggs & Stratton 40445 for simplicity, convenience and price. This appliance is definitely aimed more at everyday residential consumers rather than those who with a lot of technical knowledge.

As far as cons go, you do have to purchase the Basic Wireless Monitor separately to keep an eye on your generator with ease. There are also no cables included for installation, so this is another added cost. Make sure to calculate in these costs before you decide whether to buy this generator!

What is great about the Westinghouse WH7500E is that minimal assembly is required and you receive a full tool kit and even the oil you need to get started. So you can get up and running quickly, even if you are a novice with generators. It is hard to beat the WH7500E for ease-of-use.

Westinghouse WH7500E Portable Generator Video Review

Pros and Cons

Buyers report that the WH7500E is easy to start and is built out of sturdy, durable materials which stand up to plenty of use. While it is quite heavy (200 pounds), the wheels and handle make it easy to push around. While not particularly quiet, it is also not overly loud. It should provide you with sufficient power for most of your home appliances. Shoppers who updated their reviews years later say that the generator continues to perform great.

What drawbacks are most commonly reported? Some customers have mentioned that there is a low oil warning even when there is plenty of oil. Aside from this design flaw, most of the problems reported by customers involve shipping. This is common when ordering online. On the whole, there are very few complaints about the Westinghouse WH7500E, making it one of the best generators out there.

Along with its ease-of-installation and use, the DuroStar DS4000S runs very quietly. If you have it running outside your home, you probably will not be able to hear it from indoors. If you bring it with you to a campsite, it should be sufficiently quiet so as not to cause a major disturbance. It seems it is a very durable unit as well; customers who bought the unit and updated their review months or years later mentioned that it still runs great.

Any drawbacks? You will have to install the wheel kit on your own, and this can be difficult because of the location of the bolts, not to mention the different wrench sizes which you need to deal with all the nuts and bolts. A couple of customers also mentioned that the unit did not come with a fuel gauge.

Pros and Cons

Customers report that this is a great purchase which actually exceeds the specs and performance of many other inverter generators within the same price range (and a few that cost more).

Westinghouse WH2000iXLT Review

Rating: 4.4 / 5.0

Next up is another Westinghouse generator, the WH2000iXLT gas-powered portable inverter. This generator is also extremely popular, with more than 650 customer reviews and an average rating of 4.5 out of 5 stars. You can purchase it for $500-$700.

Key Features:

  • 1,800 running watts
  • 2,200 starting watts
  • Weighs just 43 pounds
  • Compact design: 17.8 x 12.5 x 20.3 inches

  • 13 hours at 25% load
  • EPA & CARB compliant
  • You have the option to connect this generator with another using a parallel cord
  • Backed by a two-year limited manufacturer’s warranty

What This Generator is Best For:

Inverter generators like the Westinghouse WH2000iXLT tend to operate more quietly than conventional generators, and they also can be manufactured with a much more compact and lightweight design. On top of that, they offer you high fuel efficiency. This makes them the most portable option around—even more so than conventional portable generators on wheels like those discussed previously. Bring the Westinghouse WH2000iXLT to your campsite or opt for it in a neighborhood with strict noise pollution rules.

Why Choose the Westinghouse WH2000iXLT?

The Westinghouse WH2000iXLT features cutting-edge technology for enhanced fuel efficiency. With traditional generators, the engine runs at a constant speed, no matter what the load is. The WH2000iXLT on the other hand has an engine which varies its speed based on the load, which lessens its power consumption. This helps you to conserve gas and save money. The double-insulated acoustic hood, asymmetrical fans and dual muffler all help to keep the inverter quiet.

Pros and Cons

You will be hard-pressed to find major complaints about the Westinghouse WH2000iXLT. Customers appreciate how quietly the unit runs, which makes it ideal for camping trips. It starts easily within a couple of pulls and does a great job conserving fuel. It is lightweight and small enough that it can easily be moved from location to location. It does ship without a grounding cord, which is one drawback, as you do need one, and will therefore have to buy it separately.

Why Choose the WEN 56200i?

The customer reviews for the WEN 56200i are quite extensive and favorable. You can find a great deal of information about what to expect from reading them, and as you will see, the pros greatly outweigh the cons.

Pros and Cons

The WEN 56200i is a powerful little generator which provides reliable, quiet performance. It can easily rival more expensive generators; in fact, one reviewer mentioned that it can compete with the Yamaha EF2000is, which is around twice as expensive. Indeed, the WEN 56200i seems to be patterned off of the EF2000is.

Pros include the price, quality construction, energy efficiency, portability, and quiet performance. As far as cons go, there is no fuel valve, and several customers mentioned a design flaw involving putting oil in. Interestingly enough, WEN responds to almost all customer complaints directly and personally (the responses are not all form replies—they speak to the issue), which is very impressive. So the WEN 56200i looks to be an outstanding deal.

Choosing a Generator for your Home

Hopefully reading these reviews about the best home generators, you have learned a lot more about what you can expect if you buy a standby, portable or inverter generator. A portable generator can save you a lot of money and offer you strong performance and ease-of-use. An inverter generator will cost you a bit more, but you will find it is even more compact, convenient, and fuel-efficient—so it can save you money over the long run. Standby generators can be quite pricey and can also be very hard to install and maintain without the right level of expertise. There are situations however where they are necessary.

Be sure to regularly inspect your generator. Check for damage, accumulating dust, and other issues which may hinder performance or cause a safety issue. If you need to, take the generator in to be serviced by a pro who can keep it in working order.

It is a lot of work getting set up with a generator, but once you have a backup supply of power, you will feel (and be) a lot safer during power cuts and other emergencies!
