Description

The EG4050 was designed for every situation with a convenient array of power outlets and the wattage to back them up. Four standard outlets and a locking outlet make sure that you'll have enough space for all your devices, and rubber covers protect them all against moisture and dirt.

Zoom on the Energizer EG4050

In summary, the Energizer EG4050 is a portable generator especially useful for:

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

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 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 3000W and also a peak wattage of 4050W.

This generator gets running thanks to a simple traditional pull-start mechanism.

With a full tank, the EG4050 can operate for around 10.6 hours at 50% load (fuel consumption around 0.38 GPH), thanks to its fuel capacity of 4 gallons.

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

With its dimensions of L25 x W22.6 x H21 in, the conventional, open frame design of the Energizer EG4050 offers stability and allows the generator to be raised above ground level. The device has been designed for tough environments and demanding outdoor use.

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. However, its challenging mobility is solved by its wheel kit and its folding handle, which will ease its displacement, once it is on the floor.

Features

Panel of the Energizer EG4050

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, a light indicator allows you to instantly see if its oil levels are insufficient.

The generator allows for a quick, easy and convenient assessment of its gas level, as it is equipped with a built-in fuel gauge.

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.

Accessory-wise, along with the previously mentioned features, the Energizer EG4050 is packaged with the standard documentation and an owner's manual, helping you start the device 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).

  • 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. In terms of weight, one of the champions in their power range is the Generac GP3300i, standing at just 59.5 lbs.
  • 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. If concerned with autonomy, one of the products of a comparable power output, which offers the highest run time, is the Predator 4375, boasting with around 16 hours.
  • The run time is important, but also hugely depends on the capacity of the fuel tank and doesn't mean much if we don't talk about fuel consumption as well. 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 are concerned with gasoline efficiency, having a fuel consumption of just 0.17 GPH, the Westinghouse iGen4200 is a device you should 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

STRENGTHS:
  • In the expected price range
AVERAGE SPECS:
  • Decent weight (102 lbs)
  • Decent run time
WEAKNESSES:
  • No electric start
  • Low fuel efficiency
