Description
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
- People occasionally participating in outdoor fairs, festivals or events
- 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
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 houses a 270 cc Lifan OHV 4-stroke engine, which provides 120V, consumes gasoline and delivers a running wattage of 3800W along with a peak wattage of 4100W.
The inverter generator is rated for a noise of 57 dBA (less noisy than a refrigerator). Its starting mechanisms include a simple traditional pull-start mechanism and a convenient and easy-to-use electric starter (battery included). 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.
The ESI 4000iER-EFI-CA can operate for around 12 hours at 50% load with a full tank (fuel consumption around 0.29 GPH), due to its fuel capacity of 3.5 gallons.
Delicate electronics can be plugged in an AC outlets safely, as the ESI 4000iER-EFI-CA generates a clean sine wave, reaching a <2% Total Harmonic Disruption (THD).
Outlets
The control panel features the upcoming 4 AC outlets:
In addition, it provides 1 DC outlet: there's a 12V 8A receptacle allowing you to easily charge your batteries.
This Lifan generator is RV Ready, as it features a TT-30R receptacle (TT stands for 'Travel Trailer').
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. The design follows the contemporary trends and is perfect for recreationally generating power.
While the generator is considered to be technically 'portable' (in the sense that you can move it), manually lifting and transporting it may be challenging, due to its high weight of 132 lbs. Still, once it is on the ground, its wheel kit and its folding handle can easily solve the issue of low mobility and allow for easy relocation of the device.
Features
A digital data center, one of the features of the ESI 4000iER-EFI-CA’s control panel, gives you information on the lifetime run hours, power output, fuel level and voltage, and thus, is helpful for the monitoring of its activity and status.
In addition to this info, when its oil levels are insufficient, you will be informed by the featured light indicator.
A built-in fuel gauge allows for a quick, easy and convenient check of the fuel level of the inverter generator.
As for its security measures, the device features an automatic low oil shut-off and an overload protection (circuit breaker), letting you use it with a peace of mind.
Along the basic documentation and an owner's manual (opens in a new tab), useful for starting the generator right away, the Lifan ESI 4000iER-EFI-CA's package also includes these accessories: tool kit, battery charger, key fob, RV adapter and battery charging cables.
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).
- With a dry weight of 132 pounds, the Lifan ESI 4000iER-EFI-CA finds itself in the expected weight range for generators able to produce between 3500 and 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.
- As its lowest possible noise is rated at 57 dBA, this inverter generator qualifies as one of the more quiet of the products 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.
- As the ESI 4000iER-EFI-CA offers around 12 hours run time on a full tank at a 50% load, it falls within the average autonomy range among the generators of a similar power. If autonomy is your priority, one of the devices of a similar power output with the highest run time is the Honda EB4000X, reaching around 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. 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 fuel consumption is your top priority, we suggest to check out the Westinghouse iGen4200, which has a fuel consumption of only 0.17 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 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.
