Zoom on the Energizer eZV4800

In a nutshell, the Energizer eZV4800 is a compact portable inverter generator mostly geared towards:

  • 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
  • Professionals in need of safely powering high-intensity work or lighting equipment

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 eZV4800's design includes a gasoline-fueled 223 cc 4-stroke engine. With a 120V output, it gives a running wattage of 3600W and also a peak wattage of 4800W.

Enjoying a noise rating of 70 dBA (just as noisy as a vacuum cleaner), this inverter generator gets running thanks to a simple traditional pull-start mechanism.

With a fuel capacity of 3.2 gallons, the eZV4800 may run for up to 11.5 hours with a full tank (fuel consumption around 0.28 GPH).

Sensitive electronics can be safely plugged in the AC outlets, as the eZV4800 produces a clean sine wave, with a <5% Total Harmonic Disruption (THD).

Outlets

The control panel features the upcoming 3 AC outlets:

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

In addition, it provides 1 DC outlet: there's a 12V 5A receptacle with which charging your batteries is made easy.

While this Energizer generator is not RV Ready, its L5-30R receptacle can be used for a simple RV connection with an L5-30P to TT-30R adaptor.

Portability

The Energizer eZV4800 has the following dimensions: L18 x W17 x H21 in. In combination with its conventional, open frame design, they provide support and allow the generator to be raised above ground level. This type of design is ideal for tough environments and heavy outdoor use.

The eZV4800's dry weight of 78 lbs lets you use its power anywhere needed. Moreover, grabbing and moving this product is made even easier by its open frame design.

Features

The eZV4800's control panel

One of the many eZV4800's features is the data center, included in its control panel, which conveniently provides information on the lifetime run hours and thus, helps you monitor its activity and status.

In addition to this info, several light indicators serve to show you when the generator is on overload, the generator is ready and its oil levels are insufficient.

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

Security-wise, this product benefits from an overload protection (circuit breaker) and an automatic low oil shut-off, which gives you a complete peace of mind when using it.

As for its accessories, apart from the previously mentioned features, the Energizer eZV4800 also comes with the basic documentation and an owner's manual (opens in a new tab), allowing you to start it right away.

Emissions

The Energizer eZV4800 is neither EPA approved nor CARB-compliant..

However, it features a spark arrestor and therefore, can be used in forested areas.

The Energizer eZV4800 versus other generators

The following charts are provided to give you an idea of how some of the key specs of the Energizer eZV4800 compare to generators of similar power (between 3500 and 4500 W).

  • In terms of its dry weight, the Energizer eZV4800 stands at only 78 lbs, meaning that is one of the lighter devices of the 3500-4500 rated wattage category If you are concerned by weight, one of the champions in the above-mentioned power range is the WEN GN400i, with a dry weight of just 66.1 pounds.
  • Among the generators of a comparable running wattage, this inverter generator with a lowest noise of 70 dBA can be judged as noisy. For those who are looking for a less noisy device, we suggest the Cummins Onan P4500i. With just 52 dBA, it is one of the most quiet devices in this power range.
  • As far as autonomy is concerned, providing up to 11.5 hours of runtime with a full tank at a 25% load, the eZV4800 falls into the low end in comparison with other devices of a comparable power output. If autonomy is your priority, one of the devices of a similar power output with the highest run time is the Champion 200914, reaching up to 22 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 inverter generator is somewhat less fuel efficient than devices of comparable output: its estimated fuel consumption reaches 0.28 GPH at a 25% 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 0.14 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 3500-4500W generators, the Energizer eZV4800 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
  • GFCI Outlets
  • Inverter
  • Lightweight for its kind (78 lbs)
WEAKNESSES:
  • No electric start
  • No parallel ports
  • No EPA or CARB compliance
  • On the noisy side (70 dBA)
  • Relatively low run time
  • Low fuel efficiency

In the features & specifications they said that it's not RV ready why. (Asked July 08, 2020)

"Not RV-ready" simply means that the unit does not have a TT-30R outlet. Feel free to read our definition of RV-Ready for more info.

Can ezv 4800 invert power from battery pack (Asked April 16, 2021)

The unit is designed to run on gasoline, not from a battery. To invert power from a battery pack, you'd need a power inverter, not an inverter generator.

what kind of oil should be used? (Asked October 15, 2021)

For general, all-temperature use, SAE 10W-30 is recommended.
