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
  • People occasionally participating in sporting competitions, open-air performances and outdoor 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 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.

Power & Run Time

Energizer eZV4800 is equipped with a 223 cc 4-stroke engine, running on gasoline and providing 120V, boasting a running wattage of 3,600W alongside a starting wattage of 4,800W.

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

The eZV4800's fuel tank, boasting 3.2 gallons, allows it to operate for up to 11.5 hours with a full tank (with an estimated fuel consumption of 0.28 GPH).

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

Outlets

The control panel features 3 AC outlets as follows:

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

Moreover, it presents 1 DC outlet: there's a 12V 5A receptacle providing easy battery charging capabilities.

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 dimensions of L18 x W17 x H21 in, the traditional open frame design of the Energizer eZV4800 ensures stability while allowing easy maintenance access to components and promoting effective air cooling. 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. In addition, it is even easier to grab and move the generator around thanks to 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, several light indicators serve to show you when the generator is overloaded, the oil level is too low and the generator is ready.

Benefiting from its built-in fuel gauge, the inverter generator allows for easy and immediate gas level inspections.

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.

Regarding its accessories, besides the aforementioned features, the Energizer eZV4800's box includes the typical documentation and an owner's manual (opens in a new tab), letting you start it right off the bat.

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).

  • When it comes to weight, the Energizer eZV4800 tips the scales at just 78 pounds, making it one of the lighter inverter generators in the 3500 to 4500 rated wattage range. In terms of weight, one of the champions in their power range is the Genmax GM4600iAEFIC, standing at just 58.4 lbs.
  • This inverter generator, with its lowest possible noise rated at 70 dBA falls into the more noisy category, compared to other devices of a similar running wattage. If noise emissions are important to you, one of the least noisy generators of this power range is the Westinghouse iGen4500DF with only 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 inverters 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 Firman W03661OF, reaching up to 25 hours.
  • Run time is a key metric, but it's dependent on the generator's fuel tank capacity. Therefore, discussing fuel efficiency is necessary for a complete understanding. 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 minimizing fuel usage is one of your key priorities, the Champion 200988 is one of the most efficient devices with similar power output, with a gasoline consumption of only 0.16 gallons per hour.

Price comparison

As you can see from these interactive charts, 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.
