Zoom on the Lifan ESI 4000iER-EFI-CA
In summary, the Lifan ESI 4000iER-EFI-CA is a quiet and compact portable inverter generator especially useful for:
- RV travellers wishing to enhance their freedom and nomad lifestyle
- People occasionally participating in sporting competitions, open-air performances and outdoor festivals
- Homeowners who want to be able to use the most necessary devices in their household, even during a blackout
- Camping and tailgating buffs looking to enhance their experience
In the sections ahead, the power characteristics, availability of various outlets, the portability, and any additional features of the device shall be discussed, including its emission compliance information.
Power & Run Time
The Lifan ESI 4000iER-EFI-CA's design includes 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.
The inverter generator features a simple traditional pull-start mechanism and also a simple and elegant electric starter (battery included). It is rated for a noise of 57 dBA (less noisy than a quiet suburb). Moreover, to offer you even more convenience, the ESI 4000iER-EFI-CA can also be remotely started (key fob included).
The Electronic Fuel Injection (EFI) system enhances the engine's reliability, lowers fuel consumption, improves startup, reduces servicing, boosts stale fuel resistance, and offers better altitude adaptability.
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.
Outlets
The control panel includes the following 4 AC outlets:
It also sports 1 DC outlet: there's a 12V 8A receptacle with which you may charge your batteries with ease.
With its TT-30R receptacle (TT as in 'Travel Trailer'), this Lifan generator is RV Ready.
Portability
As the Lifan ESI 4000iER-EFI-CA is an inverter generator, its encased design (L24 x W18 x H20 in) offers more aesthetics than a conventional, open frame product. This type of design is the most modern and convenient way to recreationally generate power.
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, its challenging mobility is solved by its set of 4 wheels and its folding handle, which will ease its displacement, once it is on the floor.
Features
The ESI 4000iER-EFI-CA's control panel
Monitoring of the ESI 4000iER-EFI-CA's status and activity is made possible by a digital data center, which provides information on the power output, lifetime run hours, fuel level and voltage and is one of the features of its control panel.
In addition to this info, the device’s light indicator will display if its oil levels are insufficient.
The fuel level of the inverter generator can be determined quickly, easily, and conveniently with the help of its built-in fuel gauge.
Security-wise, this product benefits from an overload protection (circuit breaker) and an automatic low oil shut-off, which gives you a complete peace of mind when using it.
With the basic documentation and an owner's manual (opens in a new tab), letting you start the generator quickly, the Lifan ESI 4000iER-EFI-CA also comes with several accessories, including: battery charger, battery charging cables, key fob, RV adapter and tool kit.
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, making it usable 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).
- Having a dry weight of 132 lbs, the Lifan ESI 4000iER-EFI-CA belongs in the expected weight range for generators which produce 3500 to 4500 rated watts. 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.
- At a lowest noise rating of 57 dBA, this inverter generator is one of the quieter devices of similar power. If noise emissions are important to you, one of the least noisy generators of this power range is the Cummins Onan P4500i with only 52 dBA.
- The ESI 4000iER-EFI-CA, offering a run time of around 12 hours with a full tank at a 50% load, falls within the average autonomy range when compared to its peers. 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 Predator 4375, with around 16 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. This inverter generator can be considered as fuel efficient, due to its low estimated fuel consumption of only 0.29 GPH (gallon per hour) at 50% load, within the aforementioned wattage range. 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 interactive 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.
