Zoom on the Energizer EG4050

In a nutshell, the Energizer EG4050 is a portable generator mostly geared towards:

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

In the following paragraphs, we shall explore the power characteristics, available outlets, portability, and any additional features of the device, along with its emission compliance information.

Power & Run Time

The Energizer EG4050's engine, 212 cc (7 hp) OHV 4-stroke, fueled by gasoline, can deliver 120/240V. It provides a running wattage of 3000W and reaches a peak wattage of 4050W.

Its starting mechanism is based on a simple traditional pull-start mechanism.

With a fuel capacity of 4 gallons, the EG4050 may run for around 10.6 hours at 50% load with a full tank (fuel consumption around 0.38 GPH).

Outlets

The control panel features the upcoming 5 AC outlets:

Two Duplexes 120V 20A (5-20R)
120/240V 30A (L14-30R) receptacle

As the EG4050 holds a twist-lock L14-30R receptacle, it is transfer switch ready: you'll easily be able to connect it to your breaker box to power your home during a power outage.

Portability

The design of the Energizer EG4050 is a typical, open frame, with the dimensions of L25 x W22.6 x H21 in, offering support and stability and enabling the possibility of raising it above ground level. The generator is designed for ideal use outdoors and in rough environments.

Since the generator weighs 102 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). Nevertheless, it can still be moved quite conveniently with the help of its wheel kit and its folding handle, once it is placed on the ground.

Features

The EG4050's control panel

Monitoring of the EG4050's status and activity is made possible by a digital data center, which provides information on the voltage and is one of the features of its control panel.

In addition to this info, when the oil level is too low, you will be informed by the featured light indicator.

A built-in fuel gauge allows for a quick, easy and convenient check of the fuel level of the generator.

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

Regarding its accessories, besides the aforementioned features, the Energizer EG4050's box includes the typical documentation and an owner's manual, letting you start it right off the bat.

The Energizer EG4050 versus other generators

The following charts are provided to give you an idea of how some of the key specs of the Energizer EG4050 compare to generators of similar power (between 2500 and 3500 W).

  • At a weight of 102 pounds, the Energizer EG4050 places in the expected weight range of the generators in the 2500-3500 rated wattage range. If weight is your top priority, one of the champions in this power category is the Genmax GM3300i, weighing just 47.4 pounds.
  • Offering around 10.6 hours of running time on a full tank at 50% load, the EG4050 is within the average autonomy range of similarly powerful generators. Furthermore, considering the run times, one of the generators which have a roughly same power output, with the highest autonomy, is the Predator 4375, as it provides 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 generator is somewhat less fuel efficient than devices of comparable output: its estimated fuel consumption reaches 0.38 GPH at a 50% load. If you wish to further improve in the area of fuel efficiency, the Genmax GM3300i, which boasts with a gas consumption of only 0.22 GPH, may be the right generator for you.

Price comparison

As you can see from this interactive chart, when compared to other 2500-3500W generators, the Energizer EG4050 is on the average side of the price range.

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