Here we’re going to review the best gas generators on the market. Powerful, cheap, quiet, dual fuel options are all available. We hope this guide helps you decide which model to go for!
The Most Powerful – Briggs & Stratton Q6500The Briggs & Stratton Q6500 was designed mainly to be used as a backup or standby home generator. However, it is portable to coming with wheels fitted as standard. It’s also an inverter generator, making the power that it delivers safe for use with all appliances. We’ll take a closer look at the inverter shortly in the review.
The Q6500 is a powerful generator that has a maximum starting wattage of 6500 watts and provides thereafter 5000 watts of power continuously. Since it was designed mainly to be used as a backup generator, it is efficient.
One tank of fuel in the Q6500 is 5 gallons of gasoline. These 5 gallons are able to keep the Q6500 running at a quarter capacity for up to 14 hours.
There’s a control panel mounted on the side of the generator that’s easy to both read and use. Some of the features here include a power usage meter and a fuel gauge. Whilst you might think that these are common features, they are not necessarily. A lot of generators come without them, unfortunately.
The fuel gauge on the Q6500 ensures that you can easily and quickly see how much fuel is remaining in the tank. This helps to avoid unexpected power loss, especially when you most need it.
The power meter shows how much of the generator’s power you are using at the current time – particularly helpful so that you can see whether or not there’s enough power left to power another appliance for example.
The Briggs & Stratton Q6500 is fitted with a very advanced inverter. This inverter ensures that the power that is produced by the generator is clean, safe, and reliably stable. The current that comes from the Q6500 is safe for use with all appliances, even the smallest and most sensitive. This is due to the fact that it has less than 6% harmonic distortion.
- Maximum wattage of 6500 watts
- Running wattage of 5000 watts
- Efficient – the Q6500 uses an economic throttle system to ensure that the engine is only running as fast as it has to in order to output the current power required. This makes for an engine that can return up to 14 hours of power from a single tank of gasoline.

The Quietest – Westinghouse iGen1200The Westinghouse iGen1200 from Westinghouse is the quietest and smallest generator on our list of best gasoline generators. It weighs a tiny 33 lbs and has a carry handle on top making for extremely easy transportation and great portability. It can be easily lifted by anyone.
It’s got a starting wattage of 1200 watts, and a running wattage of 1000 watts. It’s a gas generator that’s great for a number of uses – it can be used for working in and around the house, tailgating, or camping. It’s not, however, got enough power for something like home backup support.
It’s a very quiet unit, running at only 52 decibels when it’s at a quarter of its load. The engine of the iGen1200 is in a heavily insulated enclosure. It’s fitted with mufflers too to ensure the operational sound of the generator is kept to an absolute minimum. It’s a very refined unit.
There’s a good variety of power outlets on the Westinghouse iGen1200 as well. There are two 120V standard household outlets fitted, as well as two USB ports that can be used at the same time as the larger outlets.
The good variety of power outlets make the iGen1200 a great choice if you’re planning on using a number of smaller appliances at once. For example, you could charge your phone and camera from the USB ports at the same time as making use of one of the household outlets.
The iGen1200 can be connected in parallel with any other generator from Westinghouse’s iGen series. It’s easy to do, and only takes the use of one cable. This is particularly good for the iGen1200 since it doesn’t have a particularly large maximum power output.

All-Round – Briggs & Stratton 30545The Briggs & Stratton 30545 is, in our opinion, a fantastic all-round gas generator. It’s, in fact, one of our favorite generators in general. This is largely due to the massive number of potential uses that it has.
The 30545 P3000 from Briggs & Stratton is a powerful generator that remains very portable. It’s got a maximum wattage of 3000 watts, and a running wattage of 2600 watts. This good amount of power makes the P3000 a generator that’s suitable for powering a huge amount of appliances and tools.
If you’re looking to power tools and some larger appliances in and around your home, the P3000 will be able to cater to this easily.
What’s great about this Briggs & Stratton unit is that it’s especially portable for its size. It’s not common for a generator with a maximum wattage of 3000 watts to be able to be easily lifted by and moved around by one person.
The P3000 weighs only 84 pounds and is fitted with a double carrying handle on top. If two people are available to lift the generator, it can be easily and comfortably carried. If you’d rather not carry the generator or are unable to, it’s fitted with extremely durable tires that can be pulled over all terrains without becoming punctured.
The P3000 uses technology from Briggs & Stratton to ensure that it is as efficient as is possible. When operating at its most economic, the P3000 is able to return more than 9 hours of power from only 1.5 gallons of fuel.
Being a high-end generator, this unit has got quite a few luxury features. It’s fitted with an LCD screen that shows information such as a voltmeter, fuel gauge, and an estimation as to the number of operational hours that are left in the current fuel in the generator.
The screen on the unit also shows recommended service intervals of the generator, as well as maintenance advice such as oil change intervals.
- Inverter – the inverter that’s fitted in the P3000 ensures that power output has very minimal harmonic distortion. The power is safe for devices and appliances of all sizes.
- Efficient – the generator idles automatically, and even when running the engine only runs at the speed which is required for the power output at the time
- Maximum wattage of 3000 watts
- Running wattage of 2600 watts
- LCD screen displaying service intervals
- Fuel Gauge
- Portable – the P3000 only weighs 84 lbs and comes fitted with a handle and wheel kit
- Can be loud at times
The Briggs & Stratton Q6500 is the most powerful generator on our list. It’s also got the most features and is very well-reviewed by all that have used it. It does suffer from the lack of an electric starter, however.
The Westinghouse iGen1200 is a great little unit. It’s small, very lightweight, and is very portable. It’s well suited to camping, or when you might just have one or two small appliances to power. It’s got features such as USB sockets too, allowing small devices to be powered and charged whilst larger ones are being used. It isn’t, however, all that powerful – with a running wattage of only 1000 watts.
The DuroStar DS4000S is a good generator that’s rough and well-built too. If you’re looking for a generator that’s going t be primarily used somewhere like a construction site, it’s a great choice. It’s not a good choice if you’re looking for something to directly power small devices, as there’s no inverter. The lack of inverter could result in a power output that’s unsuitable for sensitive electronics.
The Champion 76533 is an RV-ready dual fuel generator with some impressive runtimes, being able to run on either propane or regular gasoline. It is however fairly large and is difficult for one person to lift. It does come with wheels though and is CARB compliant meaning that it can be used anywhere in the USA.
The Briggs & Stratton 30545 is a fantastic generator. It’s easily portable, is powerful, and has a huge number of fantastic features – both safety and luxury. In our opinion, it is truly one of, if not the very best gas generators available. It’s difficult to find a fault with the 30545.
