Features and Functions

Portable Generator Design

The first notable feature of this portable generator is the design. The tubular frame shields the engine from the elements and holds all the components neatly in place.

The locking handle has a comfortable ergonomic grip that folds away when not in use. It helps to decrease the size and space it takes up during transport.

The never-flat wheels also allow for maximum reliable portability, withstanding even the most rugged of terrains.

Robust Engine

The functional features of the Generac GP7500e portable generator perform exceptionally well. Powered by a 420CC OHV engine, it places the valves in the cylinder head over the combustion chamber.

The Generac brand is well-known for this type of engine, which boasts longevity. The low tone muffler works to keep it operating smoothly and with minimal noise.

Low Oil Shutdown

The low-oil shutdown feature protects against unnecessary friction. It automatically monitors gas levels and will shut down to prevent engine damage.

The fuel tank capacity is large and easy to fill, allowing for a run time of more than 12 hours.

Generac also provides a simple fuel gauge so that you can monitor gasoline levels and power up as time requires.

Electric Start

The simple electric start provides a convenient one-push power-up with a recoil backup start. You can have it powered up and running in no time.

Circuit Breaker Surge Protection

The circuit breaker protected outlets are optimal for powering individual appliances simultaneously. The covered outlets provide added protection against environmental wear and tear no matter the conditions.

The covered circuit breaker protected features provide safety and peace of mind.

Hour Meter

Lastly, the hour meter has special maintenance alerts to give you a heads-up on maintenance needs. While you will have a standard 2-year warranty, proper maintenance is essential to maintain your generator’s optimal performance and longevity.

Warranty & Extras

The Generac unit comes with a two-year warranty from the original date of sale. It protects against material and manufacture defects in residential use during the 2 year period.

The warranty provides for options to replace, repair, or refund defective products. It will not cover normal wear and tear, but it does give coverage on the engine, alternators, and other components.

As far as extra coverage, Generac offers after-sales services. Simply bring your Generac product to an authorized warranty service dealer for assistance in the 2 years after purchase.*

*Note: The after-sales services will require proof of purchase, so keep your receipt from the initial purchase.

What Can It Power?

The 7500-watt generator has a maximum surge of 9375 watts A/C equivalents. Essentially, this means the Generac GP7500e can power all the small home devices and gadgets with little strain.

With 7,500 watts of output, it can run lights, cooling or heating systems, a refrigerator, and other kitchen appliances. It can also handle the power needed for supplying water and running the laundry appliances.

Simply put, this unit can power everything you need to continue your daily routine in the event of a power outage.

When operating at 50% load, the typical use period is up to 12 hours, making it on par with the top performers on the market!

What Can’t It Power?

Typically, 7500-watt power output is sufficient for all household necessities, except for a central air conditioning system.

You might find powering the central A/C system drains the power and fuel at an increased rate. This usage rate is pretty standard for a portable generator with similar wattage output.

Fortunately, if it does reach low levels, the Generac GP7500e low oil shutdown protects against damage from running the generator without sufficient oil.

Generator Generac Customer Ratings & Reviews

People have a lot to say about the GP7500e generator. It is always a good idea to give credence to real user reviews.

On the Generac site, 97% of reviewers recommend this generator and rate it 4.7 out of 5 stars. It receives high marks for features, appearance, quality, and value.

One review reports this generator is a good option for surviving natural disasters, like hurricane season in Florida. When battling nature, you want a generator with high watts, like the 9375 watts found here, and a large gas tank when getting more is a hassle.

Pros & Cons


  • Sturdy Construction – Hardy exterior steel frame and tube reinforce the chassis for extra protection, support, and strength in rugged environments.
  • Efficient Lubrication – Engine splash-type system reduces the rate of wear and tear and keeps it running like new.
  • Low-Oil Level Shutdown – Activates automatically to protect against excessive friction and ensure increased longevity.
  • Easy Operation -Beginner-friendly with no technical skill required from the start and an electric start feature and fuel gauge monitoring for ease of use. You can also track elapsed time use with the hour meter.
  • Battery Included – Quick-charge battery included from the start.
  • Fuel Economy – Large steel fuel tank can run for up to 15 hours.


  • Noise Level – Noisier than other options, making it more suitable for works sites rather than camping. The low-tone muffler and idle control will assist with reducing noise levels but not wholly.

Can a 7500 Watt Generator Run a Whole House?

Yes and no. The watts are sufficient to power a “small” house, which encompasses a standard-size home but not something along the lines of a twelve-bedroom mansion. The 7500-watt engine output and the battery can handle all your everyday housing needs for a lengthy period in the event of an outage.

Since it is gas-powered, you can charge up and refill to tank capacity to keep it running day and night, without interruptions to your energy use.

If you look at the user reviews, many customers report their Generac product ran like new for twenty years before needing a new replacement. That is an excellent use history!
