In the following paragraphs, we shall explore the power characteristics, available outlets, portability, and any additional features of the device.
Power & Run Time
The Briggs & Stratton P4500 PowerSmart
Featuring a 224 cc Briggs & Stratton OHV 4-stroke engine, the Briggs & Stratton P4500 PowerSmart operates using gasoline, providing 120V, with a running wattage of 3,700W and a starting wattage of 4,500W.
Enjoying a noise rating of 60 dBA (just as noisy as background music), this inverter generator can be started thanks to a classic hand-operated recoil starting mechanism, but also to a convenient and efficient electric starter (battery included). Furthermore, the P4500 PowerSmart can be remotely started, providing users with added ease of use (key fob included).
Featuring a 3.5 gallons fuel tank, the P4500 PowerSmart guarantees continuous power for up to 16 hours on a full tank (fuel consumption around 0.22 GPH).
Sensitive electronics can be safely plugged in the AC outlets, as the P4500 PowerSmart produces a clean sine wave, with a <3% Total Harmonic Distortion (THD).
Outlets
The control panel is equipped with the following 5 AC outlets:
In addition, it provides 2 DC outlets: there's two 5V USB ports (USB-A) perfect for conveniently charging mobile phones, tablets, and other electronic devices.
Thanks to its TT-30R receptacle (TT stands for 'Travel Trailer'), this Briggs & Stratton generator is RV Ready, making it ideal for powering recreational vehicles.
Portability
With an inverter generator design, the Briggs & Stratton P4500 PowerSmart features a closed construction (L24.5 x W17.6 x H20.36 in), enhancing aesthetics and ensuring reduced noise levels, offering a distinct advantage over standard, open frame generators. This modern design aims to provide an ideal power solution to recreational users.
Despite its weight of 104 lbs, the generator is still considered 'portable,' meaning it is movable, although its heftiness may restrict portability in certain environments or require additional considerations for transportation and setup. Nevertheless, the restricted maneuverability is counteracted by its set of 2 wheels and its telecospic handle, enabling easy shifting once the generator is set in place.
Features
The P4500 PowerSmart's control panel
Included in the control panel of the P4500 PowerSmart, a digital data center assists in tracking its status and activity by providing details on the fuel level, power output and lifetime run hours.
In addition to this info, when its oil levels are insufficient, the generator is ready and the generator is on overload, you will be informed by the featured light indicators.
The unit benefits from Briggs & Stratton’s Quiet Power Technology (QPT™), a feature designed to greatly improve its noise levels, emissions and fuel consumption. When the switch, located on the control panel, is turned ON, the engine speed increases as electrical loads are connected, and decreases as electrical loads are removed.
As far as security is concerned, the generator can be used with a peace of mind, as it features an overload protection (circuit breaker) and an automatic low oil shut-off.
The P4500 PowerSmart also benefits from Briggs & Stratton’s CO Guard™ (opens in a new tab) carbon monoxide shutdown. This new patent-pending technology uses advanced algorithms to shut down the generator when harmful levels of carbon monoxide accumulate in the generator's operating area.
Alongside the standard documentation and an owner's manual (opens in a new tab) for quick setup, the Briggs & Stratton P4500 PowerSmart is bundled with additional accessories: key fob, funnel and oil.
InfoHub™ Portable Power
The InfoHub™ app gives you real time information
Briggs & Stratton’s InfoHub™ Portable Power technology allows you to monitor your unit’s vital information such as power usage, run time and fuel level in real time, and directly from your computer or smartphone (via the InfoHub app for iOS).
Besides its monitoring features, InfoHub can also keep you informed about your P4500 PowerSmart status and maintenance needs by sending you scheduled service reminders. It also lets you customize the way your generator communicates with you and can send notifications to your local certified dealer.
Product Videos
The Briggs & Stratton P4500 PowerSmart versus other generators
The following charts are provided to give you an idea of how some of the key specs of the Briggs & Stratton P4500 PowerSmart compare to inverter generators of similar power (between 3500 and 4500 W).
- As its weight is 104 pounds, the Briggs & Stratton P4500 PowerSmart falls in the expected weight range of the inverters in the 3500-4500 rated wattage category. Weight-conscious users may find the Genmax GM4600iAEFIC appealing, as it is one of the top contenders in this power range, weighing just 58.4 pounds.
- Because this inverter generator emits noise as low as 60 dBA, it can be considered to have a pretty average expected noise rating for a device of its power. If you are concerned with noise, check out the Westinghouse iGen4500DF, which is one of the least noisy generators in its power range, with a noise rating of just 52 dBA.
- The P4500 PowerSmart's runtime of up to 16 hours at a 25% load on a full tank positions it within the average autonomy range compared to other inverter generators with similar power. If concerned with autonomy, one of the products of a comparable power output, which offers the highest run time, is the Firman W03661OF, boasting with up to 25 hours.
- Run times are important, yet thanks to their dependence on the fuel capacity, they should be judged along with the fuel consumption of the device. This inverter generator has an average fuel consumption among comparably powerful devices, as it reaches 0.22 GPH (gallon per hour) at a 25% load. If minimizing fuel usage is one of your key priorities, the Champion 201319 is one of the most efficient devices with similar power output, with a gasoline consumption of only 0.16 gallons per hour.

User Reviews
I just bought my 3700 watt continuous generator a week ago. So far, I love it, except for the gas fill. Can’t see inside the tank when filling it up. So it is easy to overflow it.. The electric fuel gauge only works when it is running. Really??? Why not keep that gauge simple like a Honda? A non electronic gauge is much better with less to go wrong. Other than that, I love it, but things may change as time goes on. Hopefully not. I previously owned 2 Honda EU3000I which I absolutely loved, and used mist of the week for many years. But Hondas are getting ridiculously expensive as well, so I figured that I’d buy a generator that offers so much more for half the price.
I own this generator and have owned it for about 6 months. It was manufactured less than a year ago. This unit hasn’t ran right since it was new. I contacted Briggs and they just told me to take it to a service center there was nothing they could do for me. I take it to the service center they referred me to. That service told me that Briggs & Stratton is the worst company to deal with and they do not support or stand behind their products. They told me there was no chance of Briggs covering the repairs of this unit even though it was well under a year old. Before I took it to the service center I tried ordering a new carb myself because I knew that is what the issue was and I needed it working for a weekend trip. The carb was on back order (obviously this is a common issue) After the first trip to the service center and spending $200 for them to “clean the carb” I took it home that night and had the same issue. I take it back they tell me it needs the carb replaced and the carb alone is $140. So now I will have over $400 into a generator that cost $1000 to start with an hasn’t ran right since it was new. I reached out to Briggs again after my experience with the service center. They won’t acknowledge my e-mails or the fact there is a know issue with the carburetor on these generators. I will never own another Briggs & Stratton product and will make it my mission to warn others to stay away. There are better options out there. I have owned a 2000 watt Champion invertor for several years and never had an issue with it!!!!!!
Purchased at a good price on sale. Shipped directly to home. It was not assembled correctly at factory. Damaged filter housing, air breather not attached, filters not oiled. Battery was at 10 Volts when it arrived. LED lights unreadable when running. Can’t see the power level or fuel level in daylight, in the shade. To get warranty / repair it has to go to a Briggs dealer. Load it up (110 lbs) and take it to them. I should have bought it from the Briggs dealer and had them demo it before I accepted it.
Other than that: I like it.
lessons learned.
Got rid of a 3500 watt B&S open frame RV generator that was LOUD. Previously had a DuroStar DS4000 that lasted three years (1200 hrs) and blew up even with regular maintenance. I have only used this generator twice but can tell it does well in fuel consumption and noise. It seems to be at least as good as the rest of the line and having bought it on sale, saved a TON over what current pricing is.
LED lights not working. Started manually.
Electric start didn’t work; Battery terminals connected
Assume battery dead??
