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

  • RV travellers who wish to upgrade their experience to another level
  • People occasionally participating in sporting competitions, open-air performances and outdoor festivals
  • 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 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 core is the 212 cc (7 hp) OHV 4-stroke engine, which runs on gasoline. With an output of 120/240V, it provides a running wattage of 3000W and a peak wattage of 4050W.

The generator features a conventional pull-start mechanism.

The EG4050 can operate for around 10.6 hours at 50% load with a full tank (fuel consumption around 0.38 GPH), due 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

Since the EG4050 bears a twist-lock L14-30R receptacle, it is transfer switch ready: it is easily connectible to a breaker box and can power your home in case of a power outage.

Portability

The Energizer EG4050 has the following dimensions: L25 x W22.6 x H21 in. In combination with its conventional, open frame design, they provide support and allow the generator to be raised above ground level. The device has been designed for tough environments and demanding outdoor use.

As the generator's weight is 102 pounds, manually moving it or transporting it may be challenging, despite the fact that it is technically considered 'portable' (movable). 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

A digital data center, one of the features of the EG4050’s control panel, gives you information on the voltage, and thus, is helpful for the monitoring of its activity and status.

In addition to this info, a light indicator shows you if its oil levels are insufficient.

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

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

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).

  • 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. 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.
  • 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. If autonomy is your priority, one of the devices of a similar power output with the highest run time is the Honda EB4000X, reaching 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 somewhat less fuel efficient than devices of comparable output: its estimated fuel consumption reaches 0.38 GPH at a 50% load. If not satisfied with the afore-mentioned fuel consumption, you may wish to check out the Westinghouse iGen4200. With a fuel consumption of as little as 0.17 GPH, it is one of the most efficient generators currently on the market.

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
