Description

LIFAN Power USA’s Energy Storm ESI4000iER-EFI is part of our Electronic Fuel Injected (EFI) Digital Inverter Generator Series. The ESI4000iER features Electric Start and Remote Start/Stop Control (remote key fob included), produces “Clean Power” with a Sine Wave Distortion of less than 2%! This unit is a perfect fit for Camping, RVing, Tailgating, or General Use around the house! (source: Lifan)

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 able to use the most necessary devices in their household, even during a blackout
  • 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 core is the 270 cc Lifan OHV 4-stroke engine, which runs on gasoline. With an output of 120V, it provides a running wattage of 3800W and a peak wattage of 4100W.

The inverter generator is rated for a noise of 57 dBA (less noisy than a conversation at home). Its starting mechanisms include a simple traditional pull-start mechanism and a convenient and easy-to-use electric starter (battery included). For additional convenience, the ESI 4000iER-EFI-CA may 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 produces a clean sine wave: thanks to a <2% Total Harmonic Disruption (THD), your sensitive electronics can be safely plugged in the AC outlets.

Outlets

The control panel features 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 allowing you to easily charge your batteries.

Thanks to its TT-30R receptacle (TT stands for 'Travel Trailer'), this Lifan generator is RV Ready.

Portability

The Lifan ESI 4000iER-EFI-CA is an inverter generator and has an encased design of the following dimensions: L24 x W18 x H20 in. Thus, it is more aesthetical than conventional, open frame products. This modern design aims to provide an ideal power solution to recreational users.

As the generator's weight is 132 pounds, manually moving it or transporting it may be challenging, despite the fact that it is technically considered 'portable' (movable). However, this lack of maneuverability is compensated by a wheel kit and a folding handle, with which you can conveniently displace it, once it's on the ground.

Features

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

One of the many ESI 4000iER-EFI-CA's features is the data center, included in its control panel, which conveniently provides information on the fuel level, power output, voltage and lifetime run hours and thus, helps you monitor its activity and status.

In addition to this info, when its oil levels are insufficient, you will be informed by the featured light indicator.

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.

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.

Apart from the typical documentation and a user manual, which lets you start it right away, the Lifan ESI 4000iER-EFI-CA also is packed along with the following accessories: RV adapter, key fob, tool kit, battery charging cables and battery charger.

Emissions

The Lifan ESI 4000iER-EFI-CA is EPA-approved and CARB-compliant. Therefore, its sale and purchase are permitted in all of the 50 states, including California.

Moreover, it features a spark arrestor, which makes it suitable 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).

  • At a weight of 132 pounds, the Lifan ESI 4000iER-EFI-CA places in the expected weight range of the 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.
  • Since this inverter generator is rated for a lowest possible noise of 57 dBA, it can be considered as one of the more quiet of the products generating similar power. 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 Westinghouse iGen4500, whose lowest noise levels reach 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 around 12 hours at a 50% load and a full tank. If autonomy is your priority, one of the devices of a similar power output with the highest run time is the Honda EB4000, reaching around 16 hours.
  • Even though run times are undoubtedly important, they are dependent on the fuel capacity to a large extent. For a more wholesome picture, we must take into consideration the fuel consumption of the generator. This inverter generator, with an estimated fuel consumption of just 0.29 GPH (gallon per hour) at 50% load, is one of the more fuel efficient generators, for the previously mentioned wattage range. If not satisfied with the afore-mentioned fuel consumption, you may wish to check out the Westinghouse iGen4200. With a fuel consumption of as little as 0.17 GPH, it is one of the most efficient generators currently on the market.

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.
