  • The 8 Best 7500 Watt Portable Generators

    1. Westinghouse WGen7500 Portable Generator – Best Overall

    Westinghouse WGen7500

    The Westinghouse WGen7500 is our choice for best overall portable generator. This model has plenty of features that we believe will get you through any emergency or outdoor event. The Westinghouse features a 7,500-watt continuous power output and lit can handle spikes up to 9,500 watts. It features a remote starter as well as a push-button start. It features a 6.6-gallon tank for extended run times and has a low oil emergency shut off to protect your engine. The control panel is easy to read, has covered outlets, and is transfer switch ready.

    The downside to the Westinghouse is the automatic choke on the engine. It’s not capable of opening and closing far enough to work all year. In cold weather, you need to close the choke to start the engine manually. Closing the choke means the remote starter is of little use when you need it the most.

    • 7,500 watts continuous
    • 6-gallon tank
    • Low-oil shutoff
    • Easy read control panel
    • Automatic choke

    2. All Power America APGG7500 Portable Generator – Best Value

    All Power America APGG7500

    The All Power America APGG7500 is our choice for best value, and we believe that after you see what it has to offer, you will agree that it’s the best 7,500-watt generator for the money. This model features an electric push-button start and has a recoil start backup in case the battery should fail. It has a 13-horsepower 389-cc air-cooled engine and a massive 6.6-gallon fuel tank able to keep the generator running for more than nine hours on a single tank of gas. It has sturdy wheels, a gas gauge, and is transfer switch ready.

    We felt that the gas tank is a little thin for its size, and we worry about how it will hold up in the long run. The outlet covers also suffer from not enough protection from the elements.

    • 13-horsepower engine
    • 6-gallon fuel tank
    • Sturdy wheels
    • Transfer switch ready
    • Thin gas tank
    • Skimpy outlet covers

    3. Cat RP7500E Gas Portable Generator – Premium Choice

    Cat RP7500E

    Buyer’s Guide

    Let’s look at a few of the things we want to look at when choosing a portable generator.

    Types of generators

    Let’s look at the different types of generators available.

    Conventional Generator

    The conventional generator has been around for a long time, and most people have at least a passing familiarity with them. They are a simple device that uses a fuel-powered engine to spin an alternator identical to the one in your automobile. The alternator produces an alternating current that powers your devices.

    The engine runs at a fixed speed and spins the alternator at a fixed speed delivering a fixed amount of electricity. The RPM of the motor directly corresponds to the amount of electricity produced by the generator. You need a finely tuned and well-maintained engine in a conventional generator. Due to its nature as a fuel-powered mechanical device, the engine will never run completely smooth, and small fluctuations in electrical current will occur. These tiny fluctuations are why a conventional generator is said to deliver “dirty” power.

    Dirty power is fine for most applications and wasn’t a big issue until the invention of sensitive digital electronics. A computer or any “computerized” device like your router, anything “smart,” and a growing number of other devices can malfunction using dirty power. Dirty power can even damage these devices.

    Inverter Generators

    An inverter generator looks a lot like a conventional generator, and it also uses a fuel-powered motor to spin an alternator. The conventional generator sends the electricity created by the alternator directly to your devices, but an inverting generator sends the electricity to a new inverting section of the generator.

    The inverting part of the generator takes the alternating current and uses technology to turn it into a direct current. The generator then uses the direct current to create a new alternating current. It might sound confusing, but the vital thing to remember is the generator creates the power frequency, not the engine.

    This feature allows the engine to run at lower RPM when the need for power is small, and it can increase RPM as the demand for current rises and gives the inverting generator three significant advantages over a conventional one.

    • The ability to lower RPM when power demand is low can significantly decrease the amount of fuel need to power the generator.
    • It can significantly reduce the amount of noise created by a generator because of the lower RPM.
    • Because the inverter section creates the alternating current independent from the engine, the power delivered is very clean and suitable for use with computer technology.

    Power Spikes

    Different devices and appliances will draw different amounts of power. Some devices draw extra power to get started and then require less as they run. When a device draws a lot of electricity for a short time, we call it a power spike. You will need to make sure your generator has enough power to handle power spikes while delivering power to any other devices attached to the generator.

    Air conditioners and refrigerators are known for power spikes. Each time these devices kick on, they create a power spike. If you have any items that you regularly use that dim the lights for a short time when you power them on, those are power spikes.

    A refrigerator only requires about 200 watts of power to operate, but when it cycles on, it creates a 1,200-watt power spike. If you want to run a refrigerator from your generator, you will need one rated for at least 1,200 watts continuous power to handle those spikes. If you’re going to use your generator to power a fridge and a 300-watt television, you will need a generator that delivers at least 1,500 watts continuous power. You always want to have more power than you need, or you can damage the generator and the devices connected to it.

    Example Watt Chart

    • A refrigerator uses 1,200 watts starting and 200 watts continuous power
    • A furnace uses 1,000 watts starting and 600 watts continuous power
    • A television has no startup surge and uses 300 watts continuous power
    • A laptop computer has no startup surge and uses 250 watts continuous power

    Engine size

    The size of the engine is going to affect the generator in several ways. A larger engine will produce more current, but it will also use more fuel and create more noise. Larger engines will also increase the size of the generator and make it less portable.

    Fuel type

    Most generators run on fuel, usually diesel, gasoline, or liquid propane. The primary concern with fuel type is lifespan. Gas goes bad relatively quickly while diesel will last much longer. Liquid propane will stay good forever.

    Dual Fuel

    Some generators use more than one fuel. The most common dual fuel system is diesel and natural gas. Dual fuel generators can save on fuel costs over time and can are better for the environment.

    Electrical Output

    How much electricity you need is the biggest question when looking for a generator. You need to add up the power requirements of every device you intend to operate with your generator and purchase one that can deliver 10 to 20 percent more power than you need.

    • Every generator on our list delivers 7,500 watts of electricity, enough to power multiple devices in a small home during an emergency power outage.


    For many people of slight build or those with bad backs, starting the generator is challenging. Traditionally, we start a generator by recoil start, which means pulling a cable like we do to start a lawnmower. However, push-button electric starters are becoming more common. Remote electric starters are also becoming available and are the most useful.

    Run Time

    Run time is how long your generator will supply power before it needs refueling. The size of the gas tank will have a significant impact on run time as will engine performance and the number of devices connected if you use an inverter type generator.

    Transfer Switch

    Most generators provide a few outlets to plug extension cords to run your appliances and devices. Many generators also come with is a transfer switch, which is a special plug that connects to your home circuit box. A transfer switch safely disconnects you from your local power grid so you can deliver power to your entire home using your generator. Disconnecting from the power grid ensures that electricity created by the generator doesn’t travel through the lines and electrocuting neighbors.

    Control panel

    As compressors become more complex and offer more features, taking time to make sure you understand how to operate the generator is quickly becoming an important step in choosing a generator. The control panel needs to be clearly labeled and easy to understand.


    For your generator to be portable, you need to be able to move it. Before you purchase any generator, make sure that you can maneuver it into place. Some generators have trailer hitches to hook to a vehicle.


    • Never use a fuel-based generator in the home.
    • Never run a fuel-based generator near any open windows or entrances to your home.
    • Always use a carbon monoxide detector when using fuel-based generators near the home.
    • Never overfill the tank.
    • Never add fuel while the generator is hot or running.
    • Never touch a hot generator.
    • Never connect the generator to the home outlets.
    • Always power on and power down with nothing connected.
    • Always use power cords rated to handle the amount of electricity required.
    • Never operate an electric generator in wet conditions
    • Always make sure the generator is properly grounded.
    • Only operate a generator on level ground.
    • Routinely inspect your generator for wear and tear.
