Zoom on the Energizer eZV4800

To sum up, the Energizer eZV4800 is a compact portable inverter generator tailored for:

  • 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 ensure that a power failure will not prevent them from working

The subsequent sections will explore in detail its power characteristics, the diverse outlets it provides, its overall portability, and the supplementary features it offers.

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.

Operating at a noise rating of 70 dBA (just as noisy as a vacuum cleaner), this inverter generator starts up with a manual recoil starter system.

With its 3.2 gallons fuel tank, the eZV4800 can operate for up to 11.5 hours when fully fueled (with fuel usage averaging around 0.28 GPH).

As the eZV4800 produces a clean sine wave, with a <5% Total Harmonic Distortion (THD), sensitive electronics may be plugged in the AC outlets safely.

Outlets

The control panel provides 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 with which charging your batteries is made easy.

Despite not having the 'RV Ready' status, this Energizer generator provides the benefit of convenient RV compatibility through its L5-30R receptacle, enabling you to easily power your RV using an L5-30P to TT-30R adaptor.

Portability

Measuring L18 x W17 x H21 in, the classic open frame construction of the Energizer eZV4800 provides stability while enabling convenient maintenance access to components and adequate air cooling. The featured design is ideal for the outdoors and all tough environments.

With a dry weight of 78 lbs, the eZV4800 is manageable, ensuring it can accompany you wherever you need power. Moreover, the open frame structure of this generator makes it easy to grab and relocate.

Features

The eZV4800's control panel

The eZV4800's control panel is equipped with a digital data center, furnishing detailed information on the lifetime run hours for you to easily track its activity and status.

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

A built-in fuel gauge allows for a quick, easy and convenient check of the fuel level of the inverter generator.

Considering security aspects, the generator boasts an overload protection (circuit breaker) and an automatic low oil shut-off, offering peace of mind throughout operation.

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.

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).

  • Considering its weight, the Energizer eZV4800 registers at a modest 78 pounds, placing it among the lighter inverter generators in the 3500 to 4500 rated wattage selection. Regarding dry weight, one of the champions in the same power range is the Genmax GM4600iAEFIC, with a dry weight of only 58.4 lbs.
  • In comparison to generators with a similar running wattage, this inverter generator's lowest emitted noise of 70 dBA can be considered noisy. If noise emissions are one of your priorities, you may want to take a look at the Westinghouse iGen5000DF. It's one of the quietest options among generators of similar power, rated at 52 dBA.
  • In terms of its autonomy, the eZV4800 can operate for up to 11.5 hours at a 25% load, placing it within the lower bracket among generators of similar type and power range. If prolonged run time is essential to your needs, you could consider the Firman W03661OF, which offers one of the highest autonomy among devices with similar power output, lasting up to 25 hours.
  • While the run time is an important parameter, it is dependent on the fuel tank's capacity and thus, doesn't say much on its own unless we consider fuel consumption as well. In fact, this inverter generator is not one of the most fuel-efficient options in the aforementioned wattage range: its estimated gasoline consumption at 25% load is around 0.28 GPH. If you're placing a high priority on fuel consumption, the Champion 201319, with a low fuel consumption rate of 0.16 GPH, could be an option to consider.

Price comparison

As you can see from these interactive charts, when compared to other 3500-4500W inverter generators, the Energizer eZV4800 is on the cheap side of the price range.

It can therefore be a really good buy if you're looking to acquire a budget generator.

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.
