Zoom on the Energizer eZV4800

In summary, the Energizer eZV4800 is a compact portable inverter generator especially useful for:

  • RV travellers looking for even more independence
  • Occasional participants of outdoor events, competitions, concerts and festivals
  • Homeowners who want to be able to use the most necessary devices in their household, even during a blackout
  • Camping and tailgating hobbyists looking for a portable power source
  • Professionals who want to be able to deliver results, even during a power failure

The following sections will present you in detail its power characteristics, the different outlets it offers, its overall portability, the extra features it benefits from, and any relevant emission compliance details.

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 is rated for a noise of 70 dBA (just as noisy as a shower). Its starting mechanism is based on a conventional pull-start mechanism.

The eZV4800 can operate for up to 11.5 hours with a full tank (fuel consumption around 0.28 GPH), due to its fuel capacity of 3.2 gallons.

The eZV4800 produces a clean sine wave: thanks to a <5% Total Harmonic Disruption (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.

While this Energizer generator is not RV Ready, its L5-30R receptacle can be used for a simple RV connection with an L5-30P to TT-30R adaptor.

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. The device has been designed for tough environments and demanding outdoor use.

With a dry weight of 78 lbs, the eZV4800 can easily follow you wherever your power needs are. Furthermore, the open frame of the generator further helps when holding and moving it to a different place.

Features

Panel of the Energizer eZV4800

The eZV4800's control panel

One of the many eZV4800's features is the data center, included in its control panel, which conveniently provides information on the lifetime run hours and thus, helps you monitor its activity and status.

In addition to this info, several light indicators serve to show you when the oil level is too low, the generator is on overload and the generator is ready.

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

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

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, 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 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.

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.

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.
