10 Best Generators [ 2023 Reviews ] - Best of Machinery (1)

Generators are a handy piece of equipment to invest in. They provide backup power to keep your home a safe and secure place to ride out a storm or electrical outage, powering your fridge, furnace, and security system. Portable generators can provide power to your RV or electrical connections for a job site when you’re not close to an electrical hookup. Having a stand-alone power source is a luxury many homes, campers, and businesses could benefit from – but it doesn’t come cheap.

A generator is an appliance used to provide electricity in areas or times with no other electricity source. Using motors and cranks, they force electric charges into their internal components through external electric circuits. They don’t technically produce electricity but instead move electrical charges to output an electrical current. In theory, this is similar to how a water pump doesn’t create water but moves it from one place to another, creating a current.

Purchasing a generator is an investment. It can be vital for those in stormy areas, who often experience blackouts, or business owners needing to run equipment on an unimproved job site. Whenever you’re spending a good deal of money on a piece of equipment, you want to make sure you’re getting the best one that’s perfectly suited to meet your needs.

Generator buyer’s guide

There are many factors to take into account when shopping for the best generator. Factors such as wattage, fuel type, and noise level can all affect your decision. These are just a few of the considerations you should keep in mind before making a purchase. This guide offers advice on how to find the right generator for you so that you can shop with confidence.

What to look for when buying the best generator

Generators are beneficial, powerful appliances that serve a multitude of purposes. They can be used as a backup power source to keep you safe, secure, and connected in your home during an emergency, natural disaster, or power cut. Portable generators can be used for RV vacations to keep your camper supplied with electricity when you’re staying in locations without hookups. You can also use them on job sites to power air compressors, nail guns, and saws.

While generators offer much versatility and provide an invaluable service, these small devices often come with a hefty price tag. This expense is justified, but this means it’s more essential that you look at all the different features on various generators to find the one best suited to your needs.

To help make the search for the best generator easier, we’ve compiled a list of features you should consider before purchasing.

Wattage

Wattage will determine how powerful the generator is and, in turn, how many appliances or other tools and devices it can power. The higher the wattage, the more expensive the generator.

  • 3000 to 4000-watt portable generators will power your RV, including the fridge, furnace, TV, and lighting circuits.
  • 5000 to 7500-watt generators will power lights and keep things like a fridge, freezer, or well pump operating, but not at the same time.
  • 7500-watt generators will keep the lights on and power most household appliances simultaneously, minus the furnace or air conditioner.
  • 10,000-watt generators generally run all critical household items, including the furnace or air conditioner, at the same time. They also power most heavy-duty tools used on a construction site.
  • 12,500-watt generators will power your entire house without missing a beat.

When looking at a generator’s wattage, there are two numbers to keep in mind. One is the starting watts, and the other is the running watts or rated watts. Household appliances, furnaces, air conditioners, and construction tools need more watts starting up. Once they’re running, the power usage drops or settles out slightly. In turn, generators will have higher starting watts than running power. Make sure the starting power is high enough for your equipment.

Standby or portable

Home standby generators are meant to automatically provide power to your entire house within seconds of a power outage. They are permanently installed and typically tap into an existing fuel source such as natural gas or propane. While very convenient and powerful, standby generators are costly.

Portable generators don’t have as much power and don’t turn on automatically like standby generators. They may not power the entire home and cannot run for an extended period, but they are much less expensive and can be moved to different locations. When looking at portable generators to power your entire home, make sure they are transfer switch-ready.

Conventional or inverter

The main technical difference between the two different types of generators is the type and amount of power each produces.

Conventional generators only produce AC, or alternating current, power. Inverter generators produce power in three phases. High-frequency AC is first produced. It is then converted to DC (direct current) and then transformed to a stable AC power. The stable sine wave produced is unique to inverter generators and considered a “clean” energy source, safe for electronics such as laptops, cell phones, and tablets.

In regards to output, conventional generators can produce upwards of 10,000 watts. Inverter generators have a much smaller output, producing 1000 to 4000 watts.

Inverter generators can also automatically adjust the engine speed to the load, making them more fuel-efficient. The engine of a conventional generator runs at a constant speed.

Run time

When shopping for a generator to provide backup or alternative power, consider what you will power with it and how long you need these items to run. Smaller generators with shorter run times are sufficient to recharge electronic devices or charge the batteries in your RV.

If you need something to power your important appliances, such as your fridge or furnace, during emergency power outages, or you’re using equipment on a construction site for eight to ten hours a day, then you should consider one with a long run-time. This will allow you to run the generator all day without a break.

Fuel type

As mentioned above, generators run on a variety of different sources. Some generators are dual-fuel, meaning they can operate on more than one source. They typically use gasoline or diesel and natural gas or propane, giving you more options in the event of a natural disaster or emergency when fuel may be hard to get. Each type has advantages and disadvantages that should be weighed when looking to purchase one.

Gasoline-powered generators are the most common for personal use. They are affordable, easy to use, and gasoline is the most readily available fuel source. Their output is lower than some other power sources; the engines are also loud and emit fumes. Gasoline can also be hard to work with when temperatures are low.

Diesel-powered generators are the least expensive to maintain and some of the most durable options available. They work much better in frigid conditions but don’t do well when it’s wet. Like gasoline generators, they are loud and give off exhaust fumes.

Natural-gas generators are a great option if your home is already configured for it, and you can hook the generator directly to your gas line. They are highly fuel-efficient and have a much lower emission level. Using a natural-gas model does come with higher installation costs, and the unit may malfunction during cold weather.

Propane generators are extremely quiet and clean-burning. They emit almost no exhaust fumes. The fuel also stores much longer than other types. On the downside, the maintenance costs of propane generators are high, and this type has the shortest life expectancy.

Solar-powered generators are the newest, most environmentally conscious type. They use solar panels to collect energy from the sun, storing it for use in electrical power. There are no gasoline costs associated with them, and they have no emissions whatsoever. They are expensive, though, they aren’t as durable, and obviously, they don’t work under cloudy conditions.

Usable location

Some generators have been manufactured to be used outside, whereas others are more suitable for indoors. Choosing where your generator will be located can really help narrow down your options. Portable generators, like those mentioned throughout this review, can be used outdoors for a camping trip or in the home. This will keep you powered during an emergency.

Remember, though, to carefully monitor your home for carbon monoxide when using a generator inside, regardless if it’s designed for indoor use or not. A safer option than having it inside is keeping it outdoors and running extension cords to your items.

Physical Size

The size of your generator will depend upon the engine size and how much fuel it holes. A larger generator will obviously power more things and run for a longer time, but it will physically take up more space. This could be a concern if you live in a house with limited storage space or are purchasing one that needs to fit into a storage compartment in your RV.

Portability

Unless you’re in the market for a home standby generator, the chances are extremely high that you’ll need to move your generator from one location to another. Therefore, when looking at portable generators, it’s important to consider how easy they are to move.

Some portable generators come with a wheel kit already on the unit. Others require you to purchase the kit separately. Make sure you look into this before buying, so you’re not hit with an unexpected expense at the checkout. Wheel kits are straightforward to install and only take a few minutes using basic tools.

If you’re purchasing a portable generator for the worksite, it may be worth looking for a model that has a lift hook bar. This allows you to lift the generator with a front-end loader or a crane, allowing you to quickly and easily transport it or take it to a higher floor.

Noise level

The engine on a generator will make noise; there’s no way around it. Some are designed to be quieter than others, but these typically have a lower output and simply don’t produce the same amount of electrical current. Depending on where you’re using your generator, the noise level may be a feature you should consider before purchasing.

Components

While these features aren’t as important as some of the others, they are beneficial. And if your budget allows for them, they’re highly recommended.

  • A fuel gauge on the tank helps you monitor fuel levels without shutting down the generator and opening the fuel reservoir.
  • An hour meter on the engine helps you keep track of how long the generator has been operating and when to perform scheduled maintenance.
  • A low oil shutdown automatically shuts the generator off when the oil levels drop below a threshold to prevent damage to the engine from lack of lubrication.

Budget

As with any kind of appliance, shopping within your price range is essential. Generators are typically an investment piece due to how beneficial, powerful and versatile they are. But you want them to last as long as possible.

Making the right choice will ensure that your money has been spent wisely. You want a generator that not only fits your needs but can be used long-term, so it will be on hand for any emergency that arises.
