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
  • Camping and tailgating hobbyists looking for a portable power source
  • Professionals who want to be able to deliver results, even during a power failure

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 design includes a gasoline-fueled 223 cc 4-stroke engine. With a 120V output, it gives a running wattage of 3600W and also a peak wattage of 4800W.

With a noise rating of 70 dBA (just as noisy as a dishwasher), the inverter generator features 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).

Sensitive electronics can be safely plugged in the AC outlets, as the eZV4800 produces a clean sine wave, with a <5% Total Harmonic Disruption (THD).

Outlets

The control panel includes the following 3 AC outlets:

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

Additionally, it features 1 DC outlet: there's a 12V 5A receptacle with which charging your batteries is made easy.

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 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. This type of design is ideal for tough environments and heavy outdoor use.

As the eZV4800's weight is only 78 lbs, it can follow you and your power needs anywhere. In addition, it is even easier to grab and move the generator around thanks to its open frame design.

Features

The eZV4800's control panel

A digital data center, one of the features of the eZV4800's control panel, gives you information on the lifetime run hours, and thus, is helpful for the monitoring of its activity and status.

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

Thanks to a built-in fuel gauge, the inverter generator allows you to quickly, conveniently and easily check the gas level at a glance.

As far as security is concerned, the generator can be used with a peace of mind, as it features an automatic low oil shut-off and an overload protection (circuit breaker).

Accessory-wise, along with the previously mentioned features, the Energizer eZV4800 is packaged with the standard documentation and an owner's manual (opens in a new tab), helping you start the device right away.

Emissions

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

However, it features a spark arrestor and thus, may 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. 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 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.
  • The eZV4800's autonomy is somewhat low end compared to devices of its power range, as it reaches only up to 11.5 hours at 25% load on a full tank. If autonomy is your priority, one of the devices of a similar power output with the highest run time is the Champion 200914, reaching up to 22 hours.
  • Autonomy holds its importance, however, it is largely dependent on the generator’s fuel capacity and so, it is nonsensible to discuss it without mentioning fuel efficiency 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

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.
