Zoom on the Energizer EG4050

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

  • RV travellers looking for even more independence
  • People occasionally participating in sporting competitions, open-air performances and outdoor festivals
  • Amateur DIY lovers
  • Homeowners in need of an emergency backup power for their essentials

In the upcoming sections, you'll discover its power characteristics, the array of outlets it presents, its overall portability, and the additional features it possesses.

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 3,000W and reaches a peak wattage of 4,050W.

Its starting mechanism relies on a standard recoil pull-rope starting 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 provides the upcoming 5 AC outlets:

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

With its twist-lock L14-30R receptacle, the EG4050 is configured to be transfer switch ready, allowing straightforward connection to your breaker box to supply backup power to your home during outages.

Portability

At L25 x W22.6 x H21 in, the standard open frame design of the Energizer EG4050 delivers stability alongside easy maintenance access to components and good air cooling. The device has been designed for tough environments and demanding outdoor use.

Though weighing 102 lbs, the generator remains classified as 'portable,' indicating its capability to be moved, though its weight could pose transport challenges. Nevertheless, thanks to its wheel kit and its folding handle (a decent solution to its lack of maneuverability), the generator can be easily moved, once placed 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, a light indicator allows you to instantly see if the oil level is too low.

Thanks to its built-in fuel gauge, the generator allows you to quickly, conveniently, and easily check the gas level at a glance.

Regarding security, the generator comes with an overload protection (circuit breaker) and an automatic low oil shut-off, providing peace of mind during operation.

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. Weight-conscious users may find the Pulsar PGD40iSCO appealing, as it is one of the top contenders in this power range, weighing just 46 pounds.
  • The EG4050, offering a run time of around 10.6 hours with a full tank at a 50% load, falls within the average autonomy range when compared to its peers. Concerning the run times, one of the several devices with a comparable output, offering the highest autonomy, is the Predator 4375, which is able to run for around 16 hours.
  • While run time matters, it's heavily influenced by the fuel tank's capacity. Hence, it's important to consider fuel efficiency alongside. This generator doesn't excel in fuel efficiency when compared to others of its kind: it consumes approximately 0.38 GPH at a 50% load. If minimizing fuel usage is one of your key priorities, the Pulsar PGD40iSCO is one of the most efficient devices with similar power output, with a gasoline consumption of only 0.22 gallons per hour.

Price comparison

As you can see from these interactive charts, 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.
