Producing a continuous 3,800 watts of clean electricity, the eZV4800 quietly powers anything, including smart electronics for construction, tailgating, hunting, and jobs around the house or workplace.

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 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 be able to deliver results, even during a power failure

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 core is the 223 cc 4-stroke engine, which runs on gasoline. With an output of 120V, it provides a running wattage of 3600W and a peak wattage of 4800W.

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

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 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

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

This Energizer generator features an L5-30R receptacle, enabling an easy RV connection via an L5-30P to TT-30R adaptor. However, it is still not quite RV ready.

Portability

The dimensions of the Energizer eZV4800, which are L18 x W17 x H21 in, and its typical, open frame design provides stability and enables the generator to be raised above ground level. The featured design is ideal for the outdoors and all tough environments.

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

Monitoring of the eZV4800's status and activity is made possible by a digital data center, which provides information on the lifetime run hours and is one of the features of its control panel.

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.

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.

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 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).

  • Regarding its weight, the Energizer eZV4800 only weighs in at 78 pounds, which means it's one of the lighter generators in the 3500-4500 rated wattage range. 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.
  • This inverter generator, with its lowest possible noise rated at 70 dBA falls into the more noisy category, compared to other devise of a similar running wattage. 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 Cummins Onan P4500i, whose lowest noise levels reach 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 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.
  • 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 fuel consumption is your top priority, we suggest to check out the Westinghouse iGen4200, which has a fuel consumption of only 0.14 GPH and thus, is one of the most efficient devices in our database.

The bottom line

STRENGTHS:
  • 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.
