Generac Portable Generator Review

Best Rated Generac Generator Review.

Portable generators are the solution when storms cause power outages, modern camping and powering onsite constructions projects.

Here is my list of the best Generac Generators online.

** FYI: links go to Amazon (which had the lowest prices)


 Top #1 Pick: Generac GP2200i Portable Generator

Check Price Button

Despite being a bit smaller, the Generac GP2200i is very powerful for it’s size.

When running it maintains 1700Wmax output of 2200W.

Powerful battery and weight of 46 pounds makes it a top choice during emergencies

It’s also one of the best for social gatherings: outdoor parties, tailgating before games or tent camping

Running max capacity the GP2200i can power:

– TV (36-inch): 500 watts
– Refrigerator: 800 watts
– PC Laptop: 400 watts

It’s also relatively quiet + comes w/ multiple outputs: laptops, mobile phones, headphones, or speakers

The Generac GP 2200 runs on AC power — more gentle current. That’s ideal for sensitive electronics items which could be damaged with too much power (phones, laptops, etc)

Lots of positive reviews has made it one of the most popular online.


  • Price: Fair
  • Power: 1700W
  • Weight: 46.6 lbs
  • Power: Gasoline
  • Gas tank size: 1.20 gallons
  • Fuel efficiency: 10.75 hours (at 25%)
  • ** Very quiet operation

Potential Flaws

  • Not the best choice for powering a RV

#2.) Generac iQ2000 Generator

Check Price Button

This is a real gem in the portable generator arsenal.

Generac iQ2000 packs a 1600W punch in a quiet and efficient way. In fact, it produces much less noise pollution than its direct rivals, the Honda E2200 and E2200i.

And that makes it the perfect choice for tent and RV camping as it promises not to disturb any people near you – and it delivers.

** It’s also great for smaller homes or apartments – it can power a variety of small to mid-size appliances if there’s a storm or electrical outage.

As an inverted generator, the iQ2000 saves lots of fuel and allows a run time of up to 5.7 hours at 50% load. This can be increased further by establishing a parallel link with another generator.

⭐⭐ Best Generac Portable Generator for Apartments ⭐⭐

This model is also smarter than its Honda counter-part. Operation is easy thanks to a handy power-dial, while flashy and sleek digital displays give you accurate readings of the remaining fuel and power capacity. You can also choose among 3 modes of operation: economy, standard and turbo.

** Generac iQ2000 decibels (dbs) is lower than the Honda EB2000i. Generac doesn’t give a decibel level because it will depend on the load capacity – full load of 1600W will be louder than running at 1000W.


  • Price: Expensive, but good price compared to similar units
  • Power: 1600W
  • Weight: Only 46.2 lbs
  • Dimensions: 20″ x 12.6″ x 16.9″
  • Power source: Gasoline Generator
  • Gas tank size: 1.06 gallons
  • Fuel efficiency: 5.7 hours at 50% load
  • Smart and compact inverter generator
  • Dead quiet – quieter than its Honda counter-part
  • Modes of operation: economy, standard and turbo
  • Best Generac Generator for solo and small-family nature retreats

Potential Flaws

  • Not powerful enough to feed an RV’s A/C system
  • Lack of wheels for improved portability

#3.) Generac GP15000e Portable Generator

Check Price Button

The beast of Generac Power Systems, the GP15000E generates a whopping 15W of power.

Five-bedroom house? No problem!

This generator will satisfy all your electrical needs in times of emergency. It has a huge 16 gallon tank which contributes to around 10 hours run time on at 50% load.

It’s a great option to have if you live in an area with potential storm damage to power systems, especially if you have important systems you want to keep running, like medical equipment or a security system.

⭐⭐ Best Generac Portable Generator for Large Homes ⭐⭐

The generator is fitted with a battery for an easy start-up. You have a plug-in battery charger in case in you need to recharge it. Additionally, the machine has an idle function feature which reduces noise and fuel consumption when there’s no electrical demand.

It has a variety of outlets, including one 50A 120/240V, one 30A 120V, four 120V and a 12 VDC battery charger. The 992cc OHV engine is supplied with an oil-filter and an air-filter.

** I personally think it’s the best Generac Generator for emergency back-up power to large households and big construction site projects


  • Price: Expensive
  • Power: 15000W
  • Dimensions: 48.5″ x 30.8″ x 38.5″
  • Weight: 373 lbs
  • Power source: Gasoline Generator
  • Gas tank size: 16 gallons (largest on my list!)
  • Fuel efficiency: 10 hours at 50%
  • Fitted with an oil filter and an air filter

Potential Flaws

  • Sort of bulky and heavy
  • Not as fuel efficient as inverter generators in the same range

#4.) Generac 5500 Generator

Check Price Button

This ‘little’ devil is build like a rock.

Quality materials, solid construction and a protective metal-tubing case ensure the generator withstands the onslaught of the outdoor elements for a long time. It does, however, require maintenance from time to time – not allowing the fuel to stagnate by renewing it every other month for example.

It generates over 5500W and has a large-enough tank — 7.2 gallons to be exact — to power up a full-size fridge, TV and A/C system for 5-6 hours. At 50% load, it will run for about 10 hours.

⭐⭐ Best Generac Portable Generator for Small Construction Jobs ⭐⭐

Additionally, the GP5500 is supplied with a low-oil automatic shutdown feature, never-flat wheels for better portability and splash lubrication for further protection of the engine parts.

I think it’s the best Generac Generator for small-to-medium-sized construction jobs requiring use of power tools


  • Price: Fair
  • Power: 5500W
  • Dimensions: 28.75″ x 26.75″ x 25″
  • Weight: 180 lbs
  • Power source: Gas Generator
  • Gas tank size: 7.2 gallons
  • Fuel efficiency: 10 hours at 50% load
  • Output: Four 120V 20A 5-20R outlets

Potential Flaws

  • Weight restricts portability
  • Could be quieter

#5.) Generac GP6500 Generator

Check Price Button

At 6500W, this generator offers more than enough power to feed even your hungriest electrical appliances for a decent period in case of a power outage.

The 389cc OHV engine is fitted with splash lubrication which significantly extends its lifespan. Additionally, a sensor will tell the motor to automatically shut down in case of low oil level.

While, at 198.3 lbs, it might be a bit too heavy for comfort, the GP6500 is designed with a hardened steel-tube cradle which allows for easy handling on the occasion it has to be lifted.

The never-flat rubber wheels are also big enough to navigate over uneven surfaces with ease.

⭐⭐ Best Generac Portable Generator for Emergency Backup Power ⭐⭐

Compared to the GP6500E, this model has a pull startinstead of an electrical onethat often starts the motor in one go. At 6.7 gallons, the tank is large and allows for up to 10 hours of run time at 50% load.

** Generac GP6500 decibels (dbs) is fairly low given its size. Generac does not state the decibel level because it’s depends on load size. Maxing out 6500W will generate the most sound.


  • Price: less than comparable generators
  • Power: 6500W
  • Weight: 198.3 lbs
  • Dimensions: 27.5 x 33.5 x 26.5
  • Power source: Gas-powered Generator
  • Gas tank size: 6.7 gallons
  • Fuel efficiency: 10 hours on a full tank at 50% load
  • Best Generac Generator for emergency back-up power

Potential Flaws

  • A lot heavier than other Generac Generators
  • No electronic micro-processing

#6.) Generac IX2000 Generator

Check Price Button

Compact, lightweight and easy to use describe this 2000W inverter generator by Generac pretty accurately.

The Eco Throttle button gives users the option of choosing to turn the fuel-saving function on and off. When ‘on’ the motor spins depending on the electrical demand, which saves a lot of energy and reduces the noise.

⭐⭐ Best Generac Portable Generator for Smaller Families ⭐⭐

Additionally, the generated power is passed through an electronic microprocessor which effectively ‘cleans’ and stabilizes the power. It may seem like a small feature, but if you’re looking to charge sensitive electronic items – such as a computer or phone – it’s much better to have a consistent power wave.

FYI — a quick burst of power can short-out (break) sensitive electronics. It’s why power adapters sell out before a big storm hits. Following an electrical outage, the influx of power coming back on can overwhelm basic appliances: televisions, computers, printers, etc.

Apart from two 120V AC outlets, the generator also has a 12V DC battery charging outlet.

Its weight of just under 52 lbs and its compact size make it very ideal for smaller families or when camping.


  • Price: Medium
  • Power: 2000W
  • Weight: 52lbs
  • Dimensions: 22″ x 12″ x 18″
  • Power source: Gas-powered Generator
  • Eco feature for power saving
  • Low noise pollution
  • ** Very Quiet operation
  • Best Generac Generator for solo or small-family tent camping

Potential Flaws

  • Low amount of outlets
  • No wheels to further improve portability

#7.) Generac GP6500E Generator

Check Price Button

Slightly different than Generac 6500, the Generac 6500e has a larger gas tank and weighs much less – just 84.4 lbs. This, and the fact it can produce up to 6500W of power, makes it a very useful piece of machinery, capable of powering most household appliances.

The GP6500E is ideal for camping, tailgating or as a back-up power in case of power outages.

⭐⭐ Best Generac Portable Generator for RV Vacations ⭐⭐

The machine boasts a 7.2 gallon gas tank which allows over 10 hours of run time at 50% load.  This makes it possible for you to enjoy the comforts of your RV’s A/C, oven, stove, boiler, lights bulbs, PC and TV for almost a full day on a single tank.

At the back you will find a 30A outlet and two 20A duplex outlets, all protected by individual circuit breakers.


  • Price: ** Very High – too much for most consumers
  • Power: 6500W
  • Weight: 84.4 lbs
  • Dimensions: 27.2″ x 27″ x 25″
  • Power source: Gasoline Generator
  • Gas tank size: 7.2 gallons
  • Fuel efficiency: 10 hours of run time at 50% load
  • Low-oil level shut-down
  • Best Generac Generator for camping with a tent or RV or tailgating

Potential Flaws

#8.) Generac 5500 Portable Generator

Check Price Button

The Generac 6672 is powered by a 5500W, 389cc OHV motor which can feed multiple power tools simultaneously. Its 6.7 gallon gas tank allows a little under 11 hours of run timeenough to last a full day’s work on a single fill.

And there’s other good news. Splash lubrication inside the motor significantly extends the life of the components, while an auto-shut-down function prevents damage in case of depleted oil.

Reading lots of reviews online I see that the Generac RS5500 is a favorite among schools and businesses. They’re used in the school gym and for sports teams when they need to power outside heaters or large fans.

⭐⭐ Best Generac Generator for Schools and Businesses ⭐⭐

This generator is also one of the easiest to start. And although a bit noisy when running, its rugged build and reliability make it a valuable back-up power tool for construction works.

At 171.8 lbs, it’s heavy, but two rugged, rubber wheels at the back make moving it around not too difficult.

** Generac RS5500 decibels (dbs) are lower than comparable generators. Generac won’t define the decibel level because it depends on load size. Running at full capacity of 5500W will generate the most noise.


  • Price: Medium
  • Power: 5500W
  • Weight: 171.8 lbs
  • Dimensions: 27.2″ x 27″ x 25″
  • Power source: Gas Generator
  • Gas tank size: 6.7 gallons
  • Fuel efficiency: 11 hours of operation at 50% load
  • Max output: 45.8A at 120V
  • Low-oil level shut-down
  • Best Generac Generator for small-sized construction works

If you don’t want to spend excessive amounts on portable generators just because of a brand name, consider buying a Generac generator.

The company produces excellent generators that fit all needs – from electrical power for camping and tailgating to emergency home back-up power and construction site back-up electrical supply.
