Description

Zoom on the Lifan ES5700E

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

  • RV travellers wishing to enhance their freedom and nomad lifestyle
  • 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 houses a 389 cc (13 hp) Lifan OHV 4-stroke engine, which provides 120V, consumes gasoline and delivers a running wattage of 5000W along with a peak wattage of 5700W.

The generator features a simple traditional pull-start mechanism and also a simple and elegant electric starter (battery not included). It is rated for a noise of 75 dBA (just slightly more noisy than a vacuum cleaner).

With a fuel capacity of 6.5 gallons, the ES5700E may run for around 10 hours at 50% load with a full tank (fuel consumption around 0.65 GPH).

Outlets

The control panel includes the following 9 AC outlets:

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

This Lifan generator isn't quite RV Ready, but it features an L5-30R receptacle, allowing a simple RV connection through an L5-30P to TT-30R adaptor.

Portability

The Lifan ES5700E has the following dimensions: L30 x W23 x H22 in. In combination with its conventional, open frame design, they provide support and allow the generator to be raised above ground level. This type of design is ideal for tough environments and heavy outdoor use.

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 190 lbs.

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.

As far as security is concerned, the generator can be used with a peace of mind, as it features an overload protection (circuit breaker) and an automatic low oil shut-off.

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).

  • At a dry weight of 190 pounds, the Lifan ES5700E is one of the heavier devices which can produce between 4500 and 5500 running watts. Regarding dry weight, one of the champions in the same power range is the Westinghouse WGen5300v, with a dry weight of only 107 lbs.
  • Among the generators of a comparable running wattage, this generator with a lowest noise of 75 dBA can be judged as noisy. If you’d prefer a less noisy device, one of the most quiet devices, which share the same power range with this one, is the Honda EU7000iS, whose lowest noise levels reach just 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 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 Cat RP5500, 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. Compared to its peers, this generator is not exactly fuel efficient, compared to similarly powerful devices, with an estimated fuel consumption of 0.65 GPH at a 50% load. If not satisfied with the afore-mentioned fuel consumption, you may wish to check out the Westinghouse WGen5300v. With a fuel consumption of as little as 0.35 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 4500-5500W generators, the Lifan ES5700E is on the cheap side of the price range.

It can therefore be a really good buy if you're looking to acquire a budget generator.

The bottom line
