5. WEN 56200i Gas Inverter Portable Generator | BEST PORTABLE INVERTER GENERATOR
If you need a very small and highly portable generator that won’t cost you a fortune and is perfect for taking to the job site, using at the campground, or for powering relatively small appliances around the home, then the WEN 56200i inverter generator might be a good option for you to look into.
The best feature this WEN 56200i inverter comes with is the inverter tech itself. This is something that helps make this generator much more fuel-efficient than anything we have looked at in our review.
Inverters can sense the power demand being put on the generator and match the power output to this; it only uses as much fuel and produces as much power as needed at any given time.
With that being said, the WEN 56200i does not have all that much power behind it, as it can produce up to 1,600 watts, thus making it the weakest generator among our reviewed products.
However, if you need it to power RV appliances, small things around the home, or various power tools, it should work just fine. What is cool is that this generator is safe for small electronics such as smartphones and tablets.
The WEN 56200i is one of the best portable generators. It is equipped with a dual three-prong 120V outlet, a 12V DC outlet, and a 5V USB port. Keep in mind that the WEN 56200i has a 1-gallon fuel tank, which can last for just over 9 hours when running at a quarter load.
However, if it’s running at full capacity, it might only last for a couple of hours on a full tank of gas. Something that you might appreciate about the WEN 56200i is that it is EPA and CARB-compliant, making it fairly eco-friendly.
Moreover, this is by far the smallest, lightest, and most portable unit among our reviewed products. What’s also nice is that this is by far the least noisy generator on our list.
What’s to like about the WEN 56200i Gas Inverter Portable Generator
What really stands out about the WEN 56200i is how portable it is. This is the kind of generator that you can pick up with a single hand and carry around to wherever you need it to be. Moreover, the fact that it is very eco-friendly is a pretty big deal.
What’s not to like about the WEN 56200i Gas Inverter Portable Generator
What’s not so great about the WEN 56200i is that it’s just not very powerful and can only power a limited number of things that don’t require too many watts. It’s just not designed for heavy or long-term use, which can also be seen by the small fuel tank.
Best Generator for Home Buyer’s Guide
Before you buy a generator for your home, there are a few important considerations that you should keep in mind.
A generator or really anything that has a fuel-powered engine should never be operated inside a closed environment. For example, you should never run a generator inside a shed or garage. An “outdoor generator” is the only generator on the market.
The gases from the exhaust contain carbon monoxide and can poison people, and can even prove fatal. Many models are now being made to shut off automatically when it detects the build-up of carbon monoxide. This helps prevent running a generator inside an enclosed space.
A generator should be run at least twenty feet away from the home and away from all doors and windows. The exhaust should also be blown away from the home.
How to Size Your Generator
When choosing the best generator for your home, you want to know how to size generator options, so you choose the appropriate model for your needs. To do this, look at starting watts and running watts.
The starting watt refers to what is needed to initially start the appliances or tools you wish to power. The running watt is needed to continuously provide these appliances and tools with the power they need, which is often less power than is required for startup.
You will find that several manufacturers have a chart that shows you the estimated power requirements for some of the more common appliances people power during an outage.
Otherwise, you can figure this out yourself by calculating the power consumption of everything you want to power and then adding them all together.
If you need to calculate the watts, multiply the voltage by the amps required to power the device. You will need to calculate the watts for each item, and if you’re using solar panels, you can factor that in and deduct your estimated usage.
Choosing the Best Generator Type
There are several generator types to choose from, and finding the best one for your home depends on your needs.
- Portable Generators: these are the most popular type of generators and are relatively compact. This is a smaller generator that is usually mounted on wheels and is easy to transport. They often use gasoline or propane as the fuel source and can be used to power smaller appliances.
- Inverter Generators: This is an alternative option for a home generator that is stationary and noisy. It has a quiet operation and uses gasoline as its power source. It adjusts the engine output to match the power needs, so you are not wasting any energy. It is a compact and fuel-efficient source of power during an outage.
- Home Standby: This home backup generator typically has a higher wattage and is large-capacity that can supply power for several hours to a few days as long as you have an available fuel source. They are fixed outside of the home and are connected to a propane fuel tank.
Type: Portable vs. Standby
First off, you want to consider the type of generator. You can go with a portable generator, which can be used at home or outside the house.
However, standby generators (also known as whole-home generators) usually have much more power making them ideal for power outages. Plus they are integrated into your home’s electrical system. They will turn on as soon as the power goes out.
Something else you may want to look for is a generator with an inverter. Inverters make it so that a generator automatically adjusts its output according to the power demand being put on it at any given time; therefore, they only use as much fuel as is needed, and therefore are very fuel-efficient.
Fuel Type and Capacity
You also want to look for fuel capacity, particularly with portable generators or motorhome generators. Some can go for up to 20 hours on a single tank, and some can barely make it 2 hours.
Also, look at what type of fuel the generator can use and whether or not it has dual fuel capabilities.
Remember that portable generators may use gas or propane, whereas standby generators can use propane or can hook right into your home’s natural gas system.
If you want a generator for your home, you may not need it to be overly portable, as a permanent setup is what you may want.
However, if you want a generator that can also be used outside of the home, consider going for one that is not too large and has wheels for portability.
You want to pay attention to how many and what types of outlets the unit has. Do you need normal household outlets, an RV outlet, twist lock outlets, DC outlets, and USB outlets? These are all possibilities, and different generators have varying combinations of these outlets.
Of course, the other thing you want to look out for is how much power the generator can produce. You need to figure out your own power requirements and then choose a generator that can meet these needs.
Best Generator for Home FAQ.
Is it Bad to Let a Generator Run Until it is Out of Fuel?
A generator should not be allowed to run until it is out of fuel. Running out of fuel can cause some serious problems if the unit is still running.
Can I Run a Portable Generator in the Rain?
While some models may be weatherproof, for the most part, you want to avoid running portable generators in the rain. However, standby generators are built to be outside, so these are fine to run in the rain.
Can I Run a Generator Indoors?
No, absolutely not. Gas generators produce toxic emissions, which can cause serious illness and even death when run indoors or in partly enclosed areas.
What Generator Is Best For Home Backup?
The best generator for home backup is one that fits your needs. This means finding a generator that can power all the appliances you need during an outage. To determine this, multiply the total watts by 1000 to find the kilowatts.
You then multiply the kilowatts by 1.25 to see what kind of power needs you require. That number will then be the minimum generator capacity required for your home.
What Should You Look For In A Home Standby Generator?
When looking for a standby generator, there are some features you may want to consider.
Automatic shutoff is an important safety feature to have for any generator you use in the home. The noise level and fuel efficiency are also two more aspects many people consider when searching for the best home standby generator.
The bottom line is that selecting a generator for your home may not be as easy as you think. There is a lot to consider, so do your homework before making a purchase.
But if you’re in search of the best home generator 2022 that will power your whole home and provide uninterrupted power, Generac Guardian Standby Generator is your best bet.
That said, you don’t want to spend thousands of dollars on a generator that doesn’t suit your needs. So either of these generators regardless of the price should be on your radar depending on your specific requirements.
Owning a generator will separate you from the rest of the herd. If it’s a temporary power solution you seek just for a few items, you can ignore the standby generator and go with an inverter generator.
The cost of the generator you’re pondering will likely be the deciding factor. But sizing a generator based on your appliances is the best strategy when considering buying a home generator.
