Zoom on the Energizer eZV4800

In summary, the Energizer eZV4800 is a compact portable inverter generator especially useful for:

  • RV travellers wishing to enhance their freedom and nomad lifestyle
  • Occasional participants of outdoor events, competitions, concerts and festivals
  • Homeowners in need of an emergency backup power for their essentials
  • Tailgating and campground aficionados with the desire of enjoying power anywhere they go
  • Professionals who want to ensure that a power failure will not prevent them from working

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 is powered by a 223 cc 4-stroke engine. It delivers 120V, runs on gasoline and offers a running wattage of 3600W as well as a peak wattage of 4800W.

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

With a full tank, the eZV4800 can operate for up to 11.5 hours (fuel consumption around 0.28 GPH), thanks to its fuel capacity of 3.2 gallons.

The eZV4800 generates a clean sine wave: providing <5% Total Harmonic Disruption (THD), delicate electronics can be plugged in its AC outlets safely.

Outlets

The control panel features the upcoming 3 AC outlets:

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

It also sports 1 DC outlet: there's a 12V 5A receptacle with which you may charge your batteries with ease.

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 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 design is ideal for rough environments and demanding outdoor use.

As the eZV4800's weight is only 78 lbs, it can follow you and your power needs anywhere. Moreover, grabbing and moving this product is made even easier by its open frame design.

Features

Panel of the Energizer eZV4800

The eZV4800's control panel

The control panel of the eZV4800 includes a digital data center, which assists you in monitoring its status and activity, as it provides information on the lifetime run hours.

In addition to this info, the device’s light indicators will display if the generator is ready, the generator is on overload and the oil level is too low.

A built-in fuel gauge allows for a quick, easy and convenient check of the fuel level of the inverter generator.

From a security standpoint, the product offers an automatic low oil shut-off and an overload protection (circuit breaker), allowing you to use it with a peace of mind.

Besides the features previously mentioned, accessory-wise, the Energizer eZV4800 comes with the usual documentation and owner's manual (opens in a new tab) needed to get you promptly started.

Emissions

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

However, it features a spark arrestor, which makes it suitable for use 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).

  • Weight-wise, the Energizer eZV4800 has only 78 lbs, which renders it one of the lighter generators which produce 3500 to 4500 rated watts. If weight matters to you, one of the champions in this power range is the WEN GN400i with only 66.1 pounds.
  • As this inverter generator has its lowest possible noise of 70 dBA, it should be considered noisier compared to its peers of a comparable running wattage. If you are concerned with noise, check out the Cummins Onan P4500i, which is one of the least noisy generators in its power range, with a noise rating of just 52 dBA.
  • As for its autonomy, the eZV4800, with an autonomy of up to 11.5 hours at a 25% load, is placed on the low end among the generators of its kind. If concerned with autonomy, one of the products of a comparable power output, which offers the highest run time, is the Westinghouse WGen3600DF, boasting with up to 18 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 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

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.
