Inverter generators are great machines to have. Like standby generators, they can be used during emergency situations where the power is knocked out in your city. Unlike traditional generators, inverter generators produce clean energy that’s safe to provide power to your delicate electronics like laptops, computers, and Smartphones. They also have great fuel efficiency so they can last longer than traditional generators on a single gallon of gasoline.
Of the numerous manufacturers of inverter generators on the planet, Briggs & Stratton is often commended for producing some of the highest quality generators available. In this article, we’re going to take a look at three of the company’s highest-rated inverter generator models: the Briggs & Stratton 30675A, 30651, and 30545.
Performance-wise, these machines are practically identical. In fact, the only main difference between these models is their surge and running wattages. Let’s take a look at these three models, and hopefully, by the end of this article, you’ll be able to decide which of them would best suit you for your outdoor or emergency needs.
Surge and Running Wattage
Briggs & Stratton 30675A
We mentioned at the beginning of this article that the main difference between these models is their surge and running wattages. Surge wattage refers to how much energy can be provided to kick-start your electronics to life. Running wattage is the steady amount of energy provided to keep your devices running. The 30675A has a surge wattage of 6,500 watts and a running wattage of 5,000 watts.
Briggs & Stratton 30651
The 30651 has a considerably lower surge and wattage rating. They are 2,200 and 1,700 watts, respectively. This machine would be more appropriate for outdoor trips and providing energy to a limited number of small devices.
Briggs & Stratton 30545
The 30545 is the middle path between the 30675A and the 30651. This machine produces 3,000 watts of surge power and can run continuously while providing 2,600 watts. Like the previous model, this machine is designed for a limited number of electronics, but it can support some large ones such as portable ACs or refrigerators.
Conclusion: Some of the most important things to consider when purchasing an inverter generator are how much power they can supply and what you need a generator for. For example, you don’t need a mega 6,000-watt machine just for camping trips where you only have two or three Smartphones that need charging. We feel that going bigger is better and the 30675A is the best in terms of how much power it can produce, but it ultimately depends on what you intend on plugging into the generator.
Runtime and Gas Tank Capacity
Briggs & Stratton 30675A
Runtime refers to how long the machine can stay active on a full tank of gas. In general, larger machines have larger gas tanks. Usually, the runtime is measured that the total load of the machine is running at only 25% capacity. The 30675A providing 1,250 watts of power can provide up to 14 hours of clean, safe energy with a full 5-gallon tank of gasoline.
Briggs & Stratton 30651
The 30651 has been known to run for upwards of 8 hours at a quarter load. The gas tank in this model is only one gallon. This, unfortunately, means that you’ll need to add fresh fuel to the tank at more frequent intervals.
Briggs & Stratton 30545
The 30545’s 1.5-gallon gas tank can provide up to 10 hours of continuous power when running at 25%. This is rather impressive, considering that many other inverter generator models with a running wattage rated at 2,600 watts commonly provide only around 6 to 8 hours of power.
Conclusion: When it comes to generators, more power means less fuel efficiency. This makes the 5-gallon tank of the 30675A considerably less efficient than the two smaller models. In terms of optimal fuel efficiency, the 30651 takes the cake. Fuel efficiency should really only be used to measure how efficient two similar-rated engines are at producing energy, and it’s not entirely comparable between a 2,200-watt generator and a beefy 6,000-watt one.
Number of Outlets
Briggs & Stratton 30675A
The number of outlets available on an inverter generator indicates how many electronics can be plugged in simultaneously. The 30675A comes with four 120V-20A outlets, a single 120V/240V-30A (lockable) outlet that can connect to your RV, and two USB ports.

Briggs & Stratton 30651
Obviously, the smaller the generator, the fewer outlets there are to plug in your electronics directly. The 30651 comes with two 120V-20A outlets, one 12V-5A DC port with a USB adapter, and a parallel port to connect two machines together.
Briggs & Stratton 30545
The 3,000-watt inverter generator model on our list comes with four 120V-20A outlets, one 12V-5A DC port, one 120V-30A outlet (lockable) for RVs, a single USB port, and a parallel port for linking two 30545s or a 30545 to a 30651.
Conclusion: Although the number of available outlets is an important consideration, your ultimate purchase decision should be based on what you need. For instance, the 30675A and the 30545 can provide power to your RV, whereas the 30651 cannot. Keep in mind that extension cords can be plugged into these machines to increase the number of electronics that can draw energy from the generator. Just be sure that the extension cord is rated safe for use with inverter generators.
Weight and Portability
Briggs & Stratton 30675A
Inverter generators are portable by nature, and its weight and overall portability should only be a secondary consideration behind the more important ones mentioned earlier. However, if you need a portable generator for your home, you might want to consider getting the 30675A since it weighs only 138 pounds, has a telescoping handle, and comes with heavy-duty 8-inch wheels.
Briggs & Stratton 30651
The smallest model here – the 2,200-watt 30651 – weighs the least at only 54.6 pounds. Because of its relatively lightweight, it doesn’t come with wheels, but it’s equipped with an H-handle for carrying the generator with ease.

Briggs & Stratton 30545
As you can already guess, the 30454, as the mid-powered machine between the small 30651 and the beefy 30675A, weighs 85 pounds. It also comes with high-quality 6-inch wheels to help to move the machine, wherever you go.
Conclusion: With great power comes great weight. Be ready to lug around a 130-plus-pound machine generator if you need 6,000 watts. We’re happy that the wheels help with gliding the 60375A and the 30545 across all sorts of terrain. The 30651 is also lightweight, so there’s practically no problem carrying it around like a briefcase, albeit a 54.6-pound briefcase.

Briggs & Stratton Comparison: Verdict
Unfortunately, we can’t tell you whether one machine is better than the other two since the customer needs to decide how much power they need for whatever purposes they need them for. If you plan on powering many large-sized electronics like a portable fridge, fan, and multiple laptops at the same time, then the Briggs & Stratton 30675A would be fine.
If you need to provide power to your RV, only the Briggs & Stratton 30675A is incapable of doing so. However, if you need limited power just for powering a single power tool, the Briggs & Stratton 30545 would fare well.
