Zoom on the Lifan ES5700

In summary, the Lifan ES5700 is a portable generator especially useful for:

  • RV travellers wishing to enhance their freedom and nomad lifestyle
  • 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 ES5700 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.

Enjoying a noise rating of 75 dBA (just slightly more noisy than a shower), this generator gets running thanks to a simple traditional pull-start mechanism.

Thanks to a fuel capacity of 6.5 gallons, the ES5700 can operate for around 10 hours at 50% load with a full tank (fuel consumption around 0.65 GPH).

Outlets

The control panel features the upcoming 9 AC outlets:

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 Lifan ES5700 has a conventional, open frame design, of the following dimensions: L27 x W20 x H22 in, which offers support and allows it to be raised above ground level. The design is ideal for rough environments and demanding outdoor use.

Although this generator is technically considered 'portable' (in the sense that it can be moved), its 179 lbs make it incredibly difficult to manually lift and transport. Never less, thanks to a wheel kit and a folding handle (a decent solution to its lack of maneuverability), the generator can be easily moved, once placed the ground.

Features

Panel of the Lifan ES5700

The ES5700's control panel

The generator allows for a quick, easy and convenient assessment of its gas level, as it is equipped with a built-in fuel gauge.

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 user manual to get you promptly started, Lifan also included a tool kit in the ES5700's packaging.

Emissions

The Lifan ES5700 is EPA approved, but NOT CARB-compliant. Thus, it cannot be purchased or sold in California.

The Lifan ES5700 versus other generators

The following charts are provided to give you an idea of how some of the key specs of the Lifan ES5700 compare to generators of similar power (between 4500 and 5500 W).

  • With a dry weight of 179 pounds, the Lifan ES5700 finds itself in the expected weight range for generators able to produce between 4500 and 5500 rated watts. Regarding dry weight, one of the champions in the same power range is the WEN 56500, with a dry weight of only 119 lbs.
  • 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 ES5700’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.
  • Autonomy holds its importance, however, it is largely dependent on the generator’s fuel capacity and so, it is nonsensible to discuss it without mentioning fuel efficiency as well. This generator is rather wasteful, compared to other devices within the aforementioned output range, when it comes to gasoline consumption, as it reaches roughly 0.65 GPH at a 50% load. If you wish to further improve in the area of fuel efficiency, the Westinghouse WGen5500, which boasts with a gas consumption of only 0.44 GPH, may be the right generator for you.

Price comparison

As you can see from this dynamic chart, when compared to other 4500-5500W generators, the Lifan ES5700 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

STRENGTHS:
  • Inexpensive
