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 outdoor fairs, festivals or events
  • 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 in need of safely powering high-intensity work or lighting equipment

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 eZV4800's engine, 223 cc 4-stroke, fueled by gasoline, can deliver 120V. It provides a running wattage of 3,600W and reaches a peak wattage of 4,800W.

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

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).

The eZV4800 produces a clean sine wave: thanks to a <5% Total Harmonic Distortion (THD), your sensitive electronics can be safely plugged in the AC outlets.

Outlets

The control panel features the following 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.

This Energizer generator isn't quite RV Ready, but it features an L5-30R receptacle, allowing a simple RV connection through an L5-30P to TT-30R adaptor.

Portability

With its dimensions of L18 x W17 x H21 in, the conventional, open frame design of the Energizer eZV4800 offers stability and allows the generator to be raised above ground level. The generator is designed for ideal use outdoors and in rough environments.

The 78 lbs of the eZV4800'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

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, some light indicators allow you to instantly see if the generator is on overload, the generator is ready and the oil level is too low.

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

From a security point of view, the generator is equipped with an overload protection (circuit breaker) and an automatic low oil shut-off, giving you a peace of mind during use.

Along with the aforementioned features, from an accessory standpoint, the Energizer eZV4800's box includes the typical documentation and an owner's manual (opens in a new tab), which will help you start your generator promptly.

Emissions

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

However, it features a spark arrestor, making it usable 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 inverter generators of similar power (between 3500 and 4500 W).

  • Regarding its weight, the Energizer eZV4800 only weighs in at 78 pounds, which means it's one of the lighter inverter generators in the 3500-4500 rated wattage range. 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.
  • Among the generators of a comparable running wattage, this inverter generator with a lowest noise of 70 dBA can be judged as noisy. If you’d prefer a less noisy device, one of the most quiet devices, which share the same power range with this one, is the Westinghouse iGen4500DF, whose lowest noise levels reach just 52 dBA.
  • Autonomy-wise, with up to 11.5 hours on a full tank at a 25% load, the eZV4800 is on the low end when compared to other inverter generators of a similar 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 Firman W03661OF, with up to 25 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. In fact, this inverter generator is not among the most fuel efficient, within the aforementioned wattage range : its estimated gasoline consumption at 25% load is around 0.28 GPH. If you are concerned with gasoline efficiency, having a fuel consumption of just 0.16 GPH, the Champion 200988 is a device you could look out for.

Price comparison

As you can see from this interactive chart, when compared to other 3500-4500W inverter 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.

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.
