Description

The Energizer eZV4500 is the no-nonsense, reliable, portable workhorse that’s ready to deliver clean power with no unnecessary frills. It’s the ultimate inverter generator for the professional who wants maximum power at a cost-effective price. Compared to other inverter generators, this open frame design with contractor inspired features packs a huge punch for its compact and portable size. Activate EcoMode and save money on fuel without sacrificing power with class-leading inverter technology, including Smart Device Protection. Producing a continuous 4,000 watts of clean electricity, the eZV4500 quietly powers anything, including smart electronics for construction, tailgating, hunting, and jobs around the house or workplace.

Zoom on the Energizer eZV4500

In summary, the Energizer eZV4500 is a compact portable inverter generator especially useful for:

  • RV travellers looking for even more independence
  • People occasionally participating in outdoor fairs, festivals or events
  • Homeowners who want to be sure of their ability to power their fridges, cooking tools, heating and lighting equipment during power failures
  • Tailgating and campground aficionados with the desire of enjoying power anywhere they go

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 eZV4500 is powered by a 224 cc Energizer OHV 4-stroke engine. It delivers 120V, runs on gasoline and offers a running wattage of 3600W as well as a peak wattage of 4500W.

The inverter generator features a conventional pull-start mechanism. It is rated for a noise of 70 dBA (just as noisy as a vacuum cleaner).

With a fuel capacity of 3.2 gallons, the eZV4500 may run for up to 11.5 hours with a full tank (fuel consumption around 0.28 GPH).

As the eZV4500 produces a clean sine wave, with a <3% Total Harmonic Disruption (THD), sensitive electronics may be plugged in the AC outlets safely. This low THD is achieved thanks to Energizer’s Dual Wave Technology, which controls both voltage and current for a pure sine wave output, under any load.

Outlets

The control panel provides the upcoming 3 AC outlets:

Duplex 120V 20A (5-20R)
120V 30A (L5-30R) receptacle

Furthermore, it has 1 DC outlet: there's a 12V 5A receptacle with which you may charge your batteries with ease.

This Energizer generator features an L5-30R receptacle, enabling an easy RV connection via an L5-30P to TT-30R adaptor. However, it is still not quite RV ready.

Portability

The Energizer eZV4500 has a conventional, open frame design, of the following dimensions: L18 x W17 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.

The 78 lbs of the eZV4500's dry weight enables you to use it anywhere you will ever need. Moreover, its open frame design makes it incredibly easy to grab the frame in order to change its location.

Features

Monitoring of the eZV4500's status and activity is made possible by a digital data center, which provides information on the lifetime run hours and is one of the features of its control panel.

In addition to this info, the light indicators show you if the oil level is too low, the generator is overloaded and the generator is ready.

The inverter generator includes a built-in fuel gauge, a quick, easy and convenient method of checking the device’s gas level.

As for its security measures, the device features an overload protection (circuit breaker) and an automatic low oil shut-off, letting you use it with a peace of mind.

Regarding its accessories, besides the aforementioned features, the Energizer eZV4500's box includes the typical documentation and an owner's manual, letting you start it right off the bat.

Emissions

The Energizer eZV4500 is EPA-approved and CARB-compliant. Thus, selling and purchasing this generator is allowed in each of the 50 states, including California.

Moreover, it features a spark arrestor and thus, may be used in forested areas.

The Energizer eZV4500 versus other generators

The following charts are provided to give you an idea of how some of the key specs of the Energizer eZV4500 compare to generators of similar power (between 3500 and 4500 W).

  • Weight-wise, the Energizer eZV4500 has only 78 lbs, which renders it one of the lighter generators which produce 3500 to 4500 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.
  • This inverter generator, with its lowest possible noise rated at 70 dBA falls into the more noisy category, compared to other devise of a similar running wattage. If noise emissions are important to you, one of the least noisy generators of this power range is the Cummins Onan P4500i with only 52 dBA.
  • Autonomy-wise, with up to 11.5 hours on a full tank at a 25% load, the eZV4500 is on the low end when compared to other generators of a similar power output. If concerned with autonomy, one of the products of a comparable power output, which offers the highest run time, is the Champion 100892, boasting with up to 22 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 inverter generator is rather wasteful, compared to other devices within the aforementioned output range, when it comes to gasoline consumption, as it reaches roughly 0.28 GPH at a 25% load. If you wish to further improve in the area of fuel efficiency, the Westinghouse iGen4200, which boasts with a gas consumption of only 0.14 GPH, may be the right generator for you.

The bottom line

STRENGTHS:
  • Inverter
  • Lightweight for its kind (78 lbs)
WEAKNESSES:
  • No electric start
  • No parallel ports
  • On the noisy side (70 dBA)
  • Relatively low run time
  • Low fuel efficiency
