Designed with camping and recreation in mind, this inverter generator is quiet, lightweight and efficient to easily enjoy the little conveniences of home anywhere you are. (source: Briggs & Stratton (opens in a new tab))

Zoom on the Briggs & Stratton P4500 PowerSmart

In a few words, the Briggs & Stratton P4500 PowerSmart is a compact portable inverter generator perfectly suited 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
  • Tailgating and campground aficionados with the desire of enjoying power anywhere they go

In the sections ahead, the power characteristics, availability of various outlets, the portability, and any additional features of the device shall be discussed.

Power & Run Time

The Briggs & Stratton P4500 PowerSmart in use

The Briggs & Stratton P4500 PowerSmart

Briggs & Stratton P4500 PowerSmart is equipped with a 224 cc Briggs & Stratton OHV 4-stroke engine, running on gasoline and providing 120V, boasting a running wattage of 3,700W alongside a starting wattage of 4,500W.

The inverter generator features a traditional recoil pull-start mechanism and also a user-friendly and efficient electric starter (battery included). It is rated for a noise of 60 dBA (just as noisy as a normal conversation). Furthermore, for added convenience, the P4500 PowerSmart offers remote starting capabilities (key fob included).

With its 3.5 gallons fuel tank, the P4500 PowerSmart can operate for up to 16 hours when fully fueled (with fuel usage averaging around 0.22 GPH).

Delicate electronics can be plugged in the AC outlets safely, as the P4500 PowerSmart generates a clean sine wave, reaching a <3% Total Harmonic Distortion (THD).

Outlets

The control panel features the upcoming 5 AC outlets:

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

Additionally, it offers 2 DC outlets: there's two 5V USB ports (USB-A) providing convenient charging capabilities for mobile phones, tablets, and other electronic devices.

The inclusion of a TT-30R receptacle (TT for 'Travel Trailer') makes this Briggs & Stratton generator RV Ready, ideal for providing power to recreational vehicles.

Portability

Since the Briggs & Stratton P4500 PowerSmart is an inverter generator, its closed design (L24.5 x W17.6 x H20.36 in) not only provides an aesthetic advantage but also contributes to reduced noise levels compared to conventional, open frame devices. The generator has a contemporary design, convenient for recreationally generating power.

Even though this device may be technically portable (as in movable), manipulation and transportation without special equipment can be a challenge, as it weighs 104 pounds. Nevertheless, it can still be moved quite conveniently with the help of its set of 2 wheels and its telecospic handle, once it is placed 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 fuel level, lifetime run hours and power output.

In addition to this info, light indicators on the device will signal if the generator is ready, the generator is on overload 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.

As for its security measures, the device features an automatic low oil shut-off and an overload protection (circuit breaker), letting you use it with a peace of mind.

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.

Apart from the standard documentation and an owner's manual (opens in a new tab) to facilitate setup, the Briggs & Stratton P4500 PowerSmart features extra accessories: oil, funnel and key fob.

InfoHub™ Portable Power

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).

  • At 104 lbs in dry weight, the Briggs & Stratton P4500 PowerSmart fits well within the typical weight bracket for inverter generators producing 3500 to 4500 rated watts. Regarding dry weight, one of the champions in the same power range is the Genmax GM4600iAEFIC, with a dry weight of only 58.4 lbs.
  • With noise emissions reaching as low as 60 dBA, this inverter generator has a noise level typical for devices of its type and power category. If you wish to prioritize minimal noise, the Westinghouse iGen4500DF stands out as one of the quietest options among generators of similar power, with a rating of 52 dBA.
  • 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 extended autonomy is what matters most to you, the Firman W03661OF could be an excellent choice, offering one of the longest run times among units in its power category, reaching up to 25 hours.
  • Run time is a key metric, but it's dependent on the generator's fuel tank capacity. Therefore, discussing fuel efficiency is necessary for a complete understanding. This inverter generator is somewhat less fuel-efficient than devices of comparable output: its estimated fuel consumption reaches 0.22 GPH at a 25% load. If you wish to get a unit of similar power, but with one of the best fuel efficiency, you could consider the Champion 200988, which has an impressively low fuel consumption of 0.16 GPH.
According to our stats, the following comparison is pretty popular: Briggs & Stratton P4500 PowerSmart vs Briggs & Stratton Q6500 QuietPower.

    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.
