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 looking for even more independence
- 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 hobbyists looking for a portable power source
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's core is the 224 cc Briggs & Stratton OHV 4-stroke engine, which runs on gasoline. With an output of 120V, it provides a running wattage of 3700W and a peak wattage of 4500W.
The inverter generator is rated for a noise of 60 dBA (just as noisy as background music). Its starting mechanisms include a simple traditional pull-start mechanism and a convenient and easy-to-use electric starter (battery included). For additional convenience, the P4500 PowerSmart may also be remotely started (key fob included).
The P4500 PowerSmart can operate for up to 16 hours with a full tank (fuel consumption around 0.22 GPH), due to its fuel capacity of 3.5 gallons.
As the P4500 PowerSmart produces a clean sine wave, with a <3% Total Harmonic Disruption (THD), sensitive electronics may be plugged in the AC outlets safely.
The control panel includes the following 5 AC outlets:
Furthermore, it has 2 DC outlets: there's two 5V USB ports (USB-A) with which you may charge electronics, for example mobile phones or tablets, conveniently.
Thanks to its TT-30R receptacle (TT stands for 'Travel Trailer'), this Briggs & Stratton generator is RV Ready.
As the Briggs & Stratton P4500 PowerSmart is an inverter generator, its encased design (L24.5 x W17.6 x H20.36 in) offers more aesthetics than a conventional, open frame product. This modern design aims to provide an ideal power solution to recreational users.
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. 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.
One of the many P4500 PowerSmart's features is the data center, included in its control panel, which conveniently provides information on the power output, lifetime run hours and fuel level and thus, helps you monitor its activity and status.
In addition to this info, some light indicators allow you to instantly see if the generator is ready, the oil level is too low and the generator is on overload.
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. It’s a welcomed additional security feature, but don’t forget to always take your generator outside (opens in a new tab).
While the standard documentation and an owner's manual (opens in a new tab), helpful for starting the device promptly, come with the Briggs & Stratton P4500 PowerSmart, the following accessories are also included: funnel, key fob and oil.
InfoHub™ Portable Power
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.
The Briggs & Stratton P4500 PowerSmart is EPA-approved and CARB-compliant. It can therefore be sold and purchased in all 50 states, including California.
Moreover, it features a spark arrestor, so it is adequate for use in forested areas.
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 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 devices which can produce between 3500 and 4500 rated watts. In terms of weight, one of the champions in their power range is the WEN GN400i, standing at just 66.1 lbs.
- With a lowest noise rating of 60 dBA, the inverter generator is one of the more quiet of the generators of similar power. If noise emissions are important to you, one of the least noisy generators of this power range is the Cummins Onan P4500i with only 52 dBA.
- The P4500 PowerSmart, falls within the average autonomy range compared to generators of a roughly same power, with a run time of up to 16 hours at a 25% load and a full tank. Furthermore, considering the run times, one of the generators which have a roughly same power output, with the highest autonomy, is the Champion 200954, as it provides up to 22 hours.
- Autonomy holds its importance, however, it is largely dependent on the generator’s fuel capacity and so, it is nonsensible to discuss it without mentioning fuel efficiency as well. In fact, this inverter generator is not among the most fuel efficient, within the aforementioned wattage range : its estimated gasoline consumption at 25% load is around 0.22 GPH. If you wish to acquire one of the most gasoline efficient products of this power range, the Westinghouse iGen4200, with a fuel consumption of 0.14 GPH could be in your good books.
As you can see from this interactive chart, when compared to other 3500-4500W 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.
