Zoom on the Energizer EG4050

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

  • RV travellers looking for even more independence
  • People occasionally participating in outdoor fairs, festivals or events
  • Handcrafting enthusiasts who wish to work on-the-go
  • Homeowners who want to be sure of their ability to power their fridges, cooking tools, heating and lighting equipment during power failures

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

Power & Run Time

The Energizer EG4050's design includes a gasoline-fueled 212 cc (7 hp) OHV 4-stroke engine. With a 120/240V output, it gives a running wattage of 3,000W and also a peak wattage of 4,050W.

Its starting mechanism is based on a conventional pull-start mechanism.

Thanks to a fuel capacity of 4 gallons, the EG4050 can operate 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 it features a twist-lock L14-30R receptacle, the EG4050 is transfer switch ready: in case of a power outage, you will be easily able to connect it to a breaker box and power your household.

Portability

The Energizer EG4050 has a conventional, open frame design, of the following dimensions: L25 x W22.6 x H21 in, which offers support and allows it to be raised above ground level. The featured design is ideal for the outdoors and all tough environments.

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. 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

To help you monitor the EG4050's status and activity, its control panel is equipped with a digital data center, giving you information on the voltage.

In addition to this info, a light indicator serves to show you when the oil level is too low.

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

As far as security is concerned, the generator can be used with a peace of mind, as it features an overload protection (circuit breaker) and an automatic low oil shut-off.

As for its accessories, apart from the previously mentioned features, the Energizer EG4050 also comes with the basic documentation and an owner's manual, allowing you to start it right away.

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).

  • Having a dry weight of 102 lbs, the Energizer EG4050 belongs in the expected weight range for generators which produce 2500 to 3500 rated watts. In terms of weight, one of the champions in their power range is the Pulsar PGD40iSCO, standing at just 46 lbs.
  • As the EG4050 offers around 10.6 hours run time on a full tank at a 50% load, it falls within the average autonomy range among the generators of a similar power. 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.
  • Run times are important, yet thanks to their dependence on the fuel capacity, they should be judged along with the fuel consumption of the device. This generator is rather wasteful, compared to other devices within the aforementioned output range, when it comes to gasoline consumption, as it reaches roughly 0.38 GPH at a 50% load. If you are concerned with gasoline efficiency, having a fuel consumption of just 0.22 GPH, the Pulsar PGD40iSCO is a device you could look out for.

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.

The bottom line
