Description

Zoom on the Lifan ES5700E

In summary, the Lifan ES5700E is a portable generator especially useful for:

  • RV travellers who wish to upgrade their experience to another level
  • People occasionally participating in outdoor fairs, festivals or events
  • 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

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 ES5700E's design includes a gasoline-fueled 389 cc (13 hp) Lifan OHV 4-stroke engine. With a 120V output, it gives a running wattage of 5000W and also a peak wattage of 5700W.

The generator is rated for a noise of 75 dBA (just slightly more noisy than a vacuum cleaner). Its starting mechanisms include a conventional pull-start mechanism and a convenient and easy-to-use electric starter (battery not included).

The ES5700E can operate for around 10 hours at 50% load with a full tank (fuel consumption around 0.65 GPH), due to its fuel capacity of 6.5 gallons.

Outlets

The control panel provides the upcoming 9 AC outlets:

Four Duplexes 120V 20A (5-20R)
120V 30A (L5-30R) receptacle

While this Lifan generator is not RV Ready, its L5-30R receptacle can be used for a simple RV connection with an L5-30P to TT-30R adaptor.

Portability

The dimensions of the Lifan ES5700E, which are L30 x W23 x H22 in, and its typical, open frame design provides stability and enables the generator to be raised above ground level. The featured design is ideal for the outdoors and all tough environments.

Even though this device may be technically portable (as in movable), manipulation and transportation without special equipment can be a challenge, as it weighs 190 pounds.

Features

Panel of the Lifan ES5700E

The ES5700E's control panel

A built-in fuel gauge allows for a quick, easy and convenient check of the fuel level of the generator.

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.

Besides the usual set of documentation and owner's manual to get you promptly started, Lifan also included a tool kit in the ES5700E's packaging.

Emissions

The Lifan ES5700E is EPA approved, but NOT CARB-compliant. Thus, it cannot be purchased or sold in California.

The Lifan ES5700E versus other generators

The following charts are provided to give you an idea of how some of the key specs of the Lifan ES5700E compare to generators of similar power (between 4500 and 5500 W).

  • With its weight of 190 lbs, the Lifan ES5700E is one of the heavier generators in the 4500-5500 rated wattage category. If weight matters to you, one of the champions in this power range is the WEN GN6000 with only 119 pounds.
  • If compared to generators capable of producing a similar running wattage, this generator with a lowest emitted noise of 75 dBA can be considered somewhat noisy. If noise emissions are important to you, one of the least noisy generators of this power range is the Honda EU7000iS with only 52 dBA.
  • The ES5700E's autonomy is somewhat low end compared to devices of its power range, as it reaches only around 10 hours at 50% load on a full tank. If concerned with autonomy, one of the products of a comparable power output, which offers the highest run time, is the Cat RP5500, boasting with around 15 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 generator is somewhat less fuel efficient than devices of comparable output: its estimated fuel consumption reaches 0.65 GPH at a 50% load. If you wish to further improve in the area of fuel efficiency, the Westinghouse WGen5300DFv, which boasts with a gas consumption of only 0.35 GPH, may be the right generator for you.

The bottom line

STRENGTHS:
  • Electric start
WEAKNESSES:
  • No data center
  • Battery not included

  • Not CARB-compliant
  • No spark arrestor
  • On the heavy side (190 lbs)
  • On the noisy side (75 dBA)
  • Relatively low run time
  • Low fuel efficiency
