Zoom on the Briggs & Stratton P4500 PowerSmart

In summary, the Briggs & Stratton P4500 PowerSmart is a compact portable inverter generator especially useful for:

  • RV travellers wishing to enhance their freedom and nomad lifestyle
  • People occasionally participating in sporting competitions, open-air performances and outdoor festivals
  • Homeowners who want to be sure of their ability to power their fridges, cooking tools, heating and lighting equipment during power failures
  • Camping and tailgating buffs looking to enhance their experience

The following sections will present you in detail its power characteristics, the different outlets it offers, its overall portability, the extra features it benefits from, and any relevant emission compliance details.

Power & Run Time

The Briggs & Stratton P4500 PowerSmart in use

The Briggs & Stratton P4500 PowerSmart

The Briggs & Stratton P4500 PowerSmart is powered by a 224 cc Briggs & Stratton OHV 4-stroke engine. It delivers 120V, runs on gasoline and offers a running wattage of 3,700W as well as a peak wattage of 4,500W.

Enjoying a noise rating of 60 dBA (just as noisy as an office), this inverter generator can be started thanks to a conventional pull-start mechanism, but also to a simple and elegant electric starter (battery included). The P4500 PowerSmart can also be remotely started, offering further convenience (key fob included).

The fuel capacity of 3.5 gallons allows the P4500 PowerSmart to operate for up to 16 hours with a full tank (fuel consumption around 0.22 GPH).

As the P4500 PowerSmart produces a clean sine wave, with a <3% Total Harmonic Distortion (THD), sensitive electronics may be plugged in the AC outlets safely.

Outlets

The control panel includes the following 5 AC outlets:

Two Duplexes 120V 20A (5-20R)
120V 30A (TT-30R) receptacle

Furthermore, it has 2 DC outlets: there's two 5V USB ports (USB-A) allowing you to conveniently charge electronics such as mobile phones and tablets.

This Briggs & Stratton generator is RV Ready, thanks to its TT-30R receptacle (TT stands for 'Travel Trailer').

Portability

The Briggs & Stratton P4500 PowerSmart is an inverter generator and has an encased design of the following dimensions: L24.5 x W17.6 x H20.36 in. Thus, it is more aesthetical than conventional, open frame products. The generator has a contemporary design, convenient for recreationally generating power.

Since the generator weighs 104 lbs, it will be incredibly difficult to manually lift it and transport it, even though it is technically considered to 'be portable' (in the sense that it is movable). However, this lack of maneuverability is compensated by its set of 2 wheels and its telecospic handle, with which you can conveniently shift it, once it's on the ground.

Features

Panel of the Briggs & Stratton P4500 PowerSmart

The P4500 PowerSmart's control panel

To help you monitor the P4500 PowerSmart's status and activity, its control panel is equipped with a digital data center, giving you information on the lifetime run hours, fuel level and power output.

In addition to this info, some light indicators allow you to instantly see if the generator is overloaded, the generator is ready and the oil level is too low.

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.

Security-wise, this product benefits from an automatic low oil shut-off and an overload protection (circuit breaker), which gives you a complete peace of mind when using it.

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. It’s a welcomed additional security feature, but don’t forget to always take your generator outside (opens in a new tab).

Besides the classic documentation and an owner's manual (opens in a new tab) to get you promptly started, the Briggs & Stratton P4500 PowerSmart also comes with some accessories: key fob, oil and funnel are included.

InfoHub™ Portable Power

generator stats on infohub app

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 or Android).

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.

Emissions

The Briggs & Stratton P4500 PowerSmart is EPA-approved and CARB-compliant. Therefore, its sale and purchase are permitted in all of the 50 states, including California.

Moreover, it features a spark arrestor and therefore, can be used in forested areas.

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).

  • Since the generator weighs in at a dry weight of 104 lbs, the Briggs & Stratton P4500 PowerSmart belongs in the expected weight range for inverters which can produce between 3500 and 4500 rated watts. If weight matters to you, one of the champions in this power range is the WEN GN400i with only 66.1 pounds.
  • Since the inverter generator's noise is rated at 60 dBA, it has the roughly average expected noise for a device of similar type and power. For those who are looking for a less noisy device, we suggest the Westinghouse iGen4500DF. With just 52 dBA, it is one of the most quiet devices in this power range.
  • The P4500 PowerSmart, falls within the average autonomy range compared to inverter generators of a roughly same power, with a run time of up to 16 hours at a 25% load and a full tank. 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.
  • While the run time is an important parameter, it is dependent on the fuel tank’s capacity and thus, doesn’t say much on its own unless we consider fuel consumption as well. This inverter generator is not fuel efficient compared to devices of similar output: its estimated fuel consumption stands at 0.22 GPH at a 25% load. If not satisfied with the afore-mentioned fuel consumption, you may wish to check out the Champion 200988. With a fuel consumption of as little as 0.16 GPH, it is one of the most efficient generators currently on the market.
According to our stats, the following comparison is pretty popular: Briggs & Stratton P4500 PowerSmart vs Briggs & Stratton Q6500 QuietPower.

Price comparison

As you can see from this interactive chart, when compared to other 3500-4500W inverter generators, the Briggs & Stratton P4500 PowerSmart is on the average side of the price range.

Therefore, this generator nicely fits in the expected budget for this kind of product.

    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.

    + PROS:
    • Everything, except....
    - CONS:
    • The fuel gauge and fill setup...

    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!!!!!!

    + PROS:
    • It's a nice size and would be perfect for an RV if they built a reliable product.
    - CONS:
    • They build a poor quality and unreliable product and offer no support to their products. Their own dealers don't want to deal with them on warranty and product issues!

    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.

    + PROS:
    • Quiet. QPT function works well.
    • Easily moved around on hard surfaces
    - CONS:
    • Poor quality control. Damaged parts at factory during assembly. Battery was dead on arrival. LED lights unreadable for power and fuel levels in daylight, even in the shade.

    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.

    + PROS:
    • Powerful enough to run everything in a 30 amp RV
    • Quiet, even though it does make some 'noise'
    • Well thought out closed design.
    - CONS:
    • Weight. Changing the oil a little tricky, but I'm retired, what else do I have to do.
