Description
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 looking for even more independence
- 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
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 conventional pull-start mechanism and a simple and elegant electric starter (battery included). The ESI 4000iER-EFI-CA can also be remotely started, offering further convenience (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.
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 provides the upcoming 4 AC outlets:
Furthermore, it has 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. This modern design aims to provide an ideal power solution to recreational users.
Even though this device may be technically portable (as in movable), manipulation and transportation without special equipment can be a challenge, as it weighs 132 pounds. Nevertheless, it can still be moved quite conveniently with the help of its set of 4 wheels and its folding handle, once it is placed on the ground.
Features
Monitoring of the ESI 4000iER-EFI-CA's status and activity is made possible by a digital data center, which provides information on the lifetime run hours, voltage, fuel level and power output and is one of the features of its control panel.
In addition to this info, a light indicator allows you to instantly see 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.
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.
While the standard documentation and an owner's manual (opens in a new tab), helpful for starting the device promptly, come with the Lifan ESI 4000iER-EFI-CA, the following accessories are also included: tool kit, battery charger, battery charging cables, RV adapter and key fob.
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).
- As its weight is 132 pounds, the Lifan ESI 4000iER-EFI-CA falls in the expected weight range of the devices in the 3500-4500 rated wattage category. In terms of weight, one of the champions in their power range is the WEN GN400i, standing at just 66.1 lbs.
- With a lowest noise rating of 57 dBA, the inverter generator is one of the more quiet of the generators of similar power. If you are concerned with noise, check out the Cummins Onan P4500i, which is one of the least noisy generators in its power range, with a noise rating of just 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 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 Honda EB4000X, with around 16 hours.
- The run time is important, but also hugely depends on the capacity of the fuel tank and doesn't mean much if we don't talk about fuel consumption as well. At an estimated fuel consumption of 0.29 GPH (gallon per hour) at 50% load, this inverter generator is a rather fuel efficient one within its wattage category. 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 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.
