Description

Zoom on the Pulsar PG4500iSR

In summary, the Pulsar PG4500iSR is a portable inverter generator especially useful for:

  • RV travellers looking for even more independence
  • People occasionally participating in outdoor fairs, festivals or events
  • Homeowners who want to be able to use the most necessary devices in their household, even during a blackout
  • 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 Pulsar PG4500iSR in use

The Pulsar PG4500iSR

The Pulsar PG4500iSR is powered by a 224 cc OHV 4-stroke engine. It delivers 120V, runs on gasoline and offers a running wattage of 3700W as well as a peak wattage of 4500W. Additionally, as the generator is parallel capable (PGiPAIRB3 parallel kit (opens in a new tab) not included), it can be linked to a second unit for more power.

The inverter generator features a conventional pull-start mechanism and also a simple and elegant electric starter (battery included). It is rated for a noise of 64 dBA (just slightly more noisy than background music). For additional convenience, the PG4500iSR may also be remotely started (key fob included).

With a fuel capacity of 3.2 gallons, the PG4500iSR may run for around 7 hours at 50% load with a full tank (fuel consumption around 0.46 GPH).

The PG4500iSR produces a clean sine wave: thanks to a <3% Total Harmonic Disruption (THD), your sensitive electronics can be safely plugged in the AC outlets.

Outlets

The control panel includes the following 3 AC outlets:

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

In addition, it provides 2 DC outlets: there's a 5V USB port with which charging of electronics like mobile phones and tablets is made convenient and a 12V 8A (cigarette lighter style) receptacle with which you may charge your batteries with ease.

With its TT-30R receptacle (TT as in 'Travel Trailer'), this Pulsar generator is RV Ready.

Portability

The Pulsar PG4500iSR's characteristic encased inverter generator design (L26 x W24 x H28 in), provides an esthetical advantage over any ordinary, open frame product. The design follows the contemporary trends and is perfect for recreationally generating power.

While the generator is considered to be technically 'portable' (in the sense that you can move it), manually lifting and transporting it may be challenging, due to its high weight of 102 lbs. Still, once it is on the ground, its set of 2 wheels (⌀5") and its telecospic handle can easily solve the issue of low mobility and allow for easy relocation of the device.

Features

Panel of the Pulsar PG4500iSR

The PG4500iSR's control panel

The light indicators show you if the generator is overloaded, the generator is ready and its oil levels are insufficient.

From a security point of view, the generator is equipped with an overload protection (circuit breaker) and an automatic low oil shut-off, giving you a peace of mind during use.

Besides the usual set of documentation and owner's manual (opens in a new tab) to get you promptly started, Pulsar also included a key fob in the PG4500iSR's packaging.

Emissions

The Pulsar PG4500iSR 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 and therefore, can be used in forested areas.

The Pulsar PG4500iSR versus other generators

The following charts are provided to give you an idea of how some of the key specs of the Pulsar PG4500iSR compare to generators of similar power (between 3500 and 4500 W).

  • As far as its dry weight is concerned, the Pulsar PG4500iSR weighs just 102 pounds and thus, it is one of the lighter 3500 to 4500 rated wattage generators. Regarding dry weight, one of the champions in the same power range is the WEN GN400i, with a dry weight of only 66.1 lbs.
  • As this inverter generator can emit noise as low as 64 dBA, it finds itself in the average expected noise for this kind of power. If you are concerned with noise, check out the Cummins Onan P4500i, which is one of the least noisy generators in its power range, with a noise rating of just 52 dBA.
  • The PG4500iSR's autonomy is somewhat low end compared to devices of its power range, as it reaches only around 7 hours at 50% load on a full tank. If autonomy is your priority, one of the devices of a similar power output with the highest run time is the Predator 4375, reaching around 16 hours.
  • Even though run times are undoubtedly important, they are dependent on the fuel capacity to a large extent. For a more wholesome picture, we must take into consideration the fuel consumption of the generator. This inverter generator is somewhat less fuel efficient than devices of comparable output: its estimated fuel consumption reaches 0.46 GPH at a 50% load. If you wish to further improve in the area of fuel efficiency, the Westinghouse iGen4200, which boasts with a gas consumption of only 0.17 GPH, may be the right generator for you.

Price comparison

As you can see from this interactive chart, when compared to other 3500-4500W generators, the Pulsar PG4500iSR is on the average side of the price range.

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