Zoom on the Lifan ESI 4000iER-EFI-CA

In a nutshell, the Lifan ESI 4000iER-EFI-CA is a quiet and compact portable inverter generator mostly geared towards:

  • RV travellers wishing to enhance their freedom and nomad lifestyle
  • Homeowners who want to be sure of their ability to power their fridges, cooking tools, heating and lighting equipment during power failures
  • Tailgating and campground aficionados with the desire of enjoying power anywhere they go

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 Lifan ESI 4000iER-EFI-CA's build contains a gasoline-fueled 270 cc Lifan OHV 4-stroke engine. With a 120V output, it gives a running wattage of 3800W and also a peak wattage of 4100W.

At a noise rating of 57 dBA (less noisy than a quiet suburb), this inverter generator can be started via a conventional pull-start mechanism, or a simple and elegant electric starter (battery included). Moreover, to offer you even more convenience, the ESI 4000iER-EFI-CA can also be remotely started (key fob included).

With a full tank, the ESI 4000iER-EFI-CA can operate for around 12 hours at 50% load (fuel consumption around 0.29 GPH), thanks to its fuel capacity of 3.5 gallons.

The ESI 4000iER-EFI-CA generates a clean sine wave: providing <2% Total Harmonic Disruption (THD), delicate electronics can be plugged in its AC outlets safely.

Here are a few examples of what this generator could allow you to simultaneously power:Note: The examples above are based on a maximum load of 75% and estimated wattages. The devices also may not be able to start at the same time. For a more accurate estimation, use our wattage calculator.

Outlets

The control panel provides the upcoming 4 AC outlets:

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

Furthermore, it has 1 DC outlet: there's a 12V 8A receptacle with which charging your batteries is made easy.

With its TT-30R receptacle (TT as in 'Travel Trailer'), this Lifan generator is RV Ready.

Portability

Since the Lifan ESI 4000iER-EFI-CA is an inverter generator, its closed design (L24 x W18 x H20 in) has an esthetical advantage over conventional, open frame devices. The design follows the contemporary trends and is perfect for recreationally generating power.

Although this generator is technically considered 'portable' (in the sense that it can be moved), its 132 lbs make it incredibly difficult to manually lift and transport. Still, once it is on the ground, a wheel kit and a folding handle can easily solve the issue of low mobility and allow for easy relocation of the device.

Features

The ESI 4000iER-EFI-CA's control panel

Monitoring of the ESI 4000iER-EFI-CA's status and activity is made possible by an illuminated data center, which provides information on the power output, voltage, lifetime run hours and fuel level and is one of the features of its control panel.

In addition to this info, a light indicator allows you to instantly see if 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.

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.

Along the basic documentation and a user manual, useful for starting the generator right away, the Lifan ESI 4000iER-EFI-CA's package also includes these accessories: key fob, RV adapter, battery charger, tool kit and battery charging cables.

Emissions

The Lifan ESI 4000iER-EFI-CA is EPA-approved and CARB-compliant. It can therefore be sold and purchased in all 50 states, including California.

Moreover, it features a spark arrestor, so it is adequate for use in forested areas.

The Lifan ESI 4000iER-EFI-CA versus other generators

The following charts are provided to give you an idea of how some of the key specs of the Lifan ESI 4000iER-EFI-CA compare to generators of similar power (between 3500 and 4500 W).

  • Since the generator weighs in at a dry weight of 132 lbs, the Lifan ESI 4000iER-EFI-CA belongs in the expected weight range for devices which can produce between 3500 and 4500 rated watts. If you are concerned by weight, one of the champions in the above mentioned power range is the Energizer eZV4500, with a dry weight of just 78 pounds.
  • With a lowest possible noise of 57 dBA, this inverter generator places itself amongst the more quiet of the products delivering similar power. If you are concerned with noise, check out the Westinghouse iGen4500, which is one of the least noisy generators in its power range, with a noise rating of just 52 dBA.
  • The ESI 4000iER-EFI-CA, falls within the average autonomy range compared to generators of a roughly same power, with a run time of 12 hours at a 50% load and a full tank. If concerned with autonomy, one of the products of a comparable power output, which offers the highest run time, is the Honda EB4000, boasting with 16 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. At an estimated fuel consumption 0.29 GPH (gallon per hour) at 50% load, this inverter generator is a rather fuel efficient one within its wattage category. If you wish to acquire one of the most gasoline efficient products of this power range, the Westinghouse iGen4200, with a fuel consumption of 0.17 GPH could be in your good books.

Price comparison

As you can see from this dynamic chart, when compared to other 3500-4500W generators, the Lifan ESI 4000iER-EFI-CA is on the average side of the price range.

Therefore, this generator nicely fits in the expected budget for this kind of product.
