The ESI7000iER 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 (opens in a new tab))

Zoom on the Lifan ESI 7000iER-EFI

In summary, the Lifan ESI 7000iER-EFI is a quiet and powerful portable inverter generator especially useful for:

  • Food van owners who know that just a short power outage could lose them hundreds of dollars
  • Homeowners who want to be sure of their ability to power their fridges, cooking tools, heating and lighting equipment during power failures
  • Camping and tailgating buffs looking to enhance their experience
  • RV travellers looking for even more independence

In the following paragraphs, we shall explore the power characteristics, available outlets, portability, and any additional features of the device, along with its emission compliance information.

Power & Run Time

The Lifan ESI 7000iER-EFI's core is the 389 cc Lifan OHV 4-stroke engine, which runs on gasoline. With an output of 120V, it provides a running wattage of 6500W and a peak wattage of 7000W.

The inverter generator features a conventional pull-start mechanism and also a convenient and easy-to-use electric starter (battery included). It is rated for a noise of 59 dBA (less noisy than rainfall). For additional convenience, the ESI 7000iER-EFI may 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 fuel capacity of 4.5 gallons, the ESI 7000iER-EFI may run for around 12 hours at 50% load with a full tank (fuel consumption around 0.38 GPH).

As the ESI 7000iER-EFI produces a clean sine wave, with a <2% Total Harmonic Distortion (THD), sensitive electronics may be plugged in the AC outlets safely.

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 you may charge your batteries with ease.

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

Portability

The Lifan ESI 7000iER-EFI is an inverter generator and has an encased design of the following dimensions: L26 x W21 x H26.5 in. Thus, it is more aesthetical than conventional, open frame products. 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 180 lbs make it incredibly difficult to manually lift and transport. However, its challenging mobility is solved by its set of wheels and its folding handle, which will ease its displacement, once it is on the floor.

Features

The ESI 7000iER-EFI's control panel

The control panel of the ESI 7000iER-EFI includes a digital data center, which assists you in monitoring its status and activity, as it provides information on the power output, fuel level, lifetime run hours and voltage.

In addition to this info, a light indicator allows you to instantly see if its oil levels are insufficient.

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 overload protection (circuit breaker) and an automatic low oil shut-off, letting you use it with a peace of mind.

Besides the classic documentation and an owner's manual (opens in a new tab) to get you promptly started, the Lifan ESI 7000iER-EFI also comes with some accessories: RV adapter, tool kit, battery charging cables, battery charger and key fob are included.

Emissions

The Lifan ESI 7000iER-EFI 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.

Product Video

The Lifan ESI 7000iER-EFI versus other generators

The following charts are provided to give you an idea of how some of the key specs of the Lifan ESI 7000iER-EFI compare to generators of similar power (between 6000 and 7000 W).

  • Having a dry weight of 180 lbs, the Lifan ESI 7000iER-EFI belongs in the expected weight range for generators which produce 6000 to 7000 rated watts. Regarding dry weight, one of the champions in the same power range is the Sportsman GEN85KIDF, with a dry weight of only 133 lbs.
  • With a lowest noise rating of 59 dBA, the inverter generator is one of the more quiet of the generators of similar power. If noise emissions are important to you, one of the least noisy generators of this power range is the Powerhorse 7500i with only 55 dBA.
  • Thanks to an impressive running time of around 12 hours at 50% load, the ESI 7000iER-EFI benefits from a higher run time than many generators of a similar output. If autonomy is your priority, one of the devices of a similar power output with the highest run time is the Generac XC6500E, reaching around 14 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. With an estimated gasoline consumption of 0.38 GPH (gallon per hour) at 50% load, this inverter generator is among the more fuel efficient of the products in the above-mentioned wattage range. If fuel consumption is your top priority, we suggest to check out the A-iPower SUA7000L, which has a fuel consumption of only 0.36 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 6000-7000W inverter generators, the Lifan ESI 7000iER-EFI is on the average side of the price range.

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

    Purchased from Home Depot. Terrible, terrible, terrible generator. Highly unreliable from the start. Diagnostic codes are almost non-existent. Hard to find someone local who can work on it. Have replaced many parts. After 23 hours of use, I’m giving up on this generator and going to replace it. Lifan parts person told me the 7000 series is a problem child. He suggested I rethink investing more money into it. Customer service is nearly non-existent. So disapointed.

    + PROS:
    • When/if it runs, it runs good. Small compact size.
    - CONS:
    • Unreliable.
