Zoom on the Energizer eZV4800

In a nutshell, the Energizer eZV4800 is a compact portable inverter 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
  • 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 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 houses a 223 cc 4-stroke engine, which provides 120V, consumes gasoline and delivers a running wattage of 3600W along with a peak wattage of 4800W.

The inverter generator is rated for a noise of 70 dBA (just as noisy as a shower). Its starting mechanism is based on a simple traditional pull-start mechanism.

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

Delicate electronics can be plugged in an AC outlets safely, as the eZV4800 generates a clean sine wave, reaching 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

Furthermore, it has 1 DC outlet: there's a 12V 5A receptacle allowing you to easily charge your batteries.

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. Furthermore, the open frame of the generator further helps when holding and moving it to a different place.

Features

The eZV4800's control panel

To help you monitor the eZV4800's status and activity, its control panel is equipped with a digital data center, giving you information on the lifetime run hours.

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

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, so it is adequate 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).

  • As far as its dry weight is concerned, the Energizer eZV4800 weighs just 78 pounds and thus, it is one of the lighter 3500 to 4500 rated wattage generators. If weight matters to you, one of the champions in this power range is the WEN GN400i with only 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. If noise emissions are one of your priorities, you may be interested in the Cummins Onan P4500i, one of the least noisy generators similarly powerful as this one, rated for 52 dBA.
  • 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 you consider autonomy on a single full tank as one of the deciding factors, one of the generators in the same power range that offers the highest run time is the Champion 200954, with 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 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 acquire one of the most gasoline efficient products of this power range, the Westinghouse iGen4200, with a fuel consumption of 0.14 GPH could be in your good books.

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

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.
