Zoom on the Lifan ES5700

In a nutshell, the Lifan ES5700 is a portable generator mostly geared towards:

  • RV travellers who wish to upgrade their experience to another level
  • People occasionally participating in sporting competitions, open-air performances and outdoor festivals
  • Food truck owners who do not wish to see their business interrupted under any circumstances
  • Homeowners in need of an emergency backup power for their essentials

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.

At a noise rating of 75 dBA (just slightly more noisy than a shower), the generator is started via a conventional pull-start mechanism.

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

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 design of the Lifan ES5700 is a typical, open frame, with the dimensions of L27 x W20 x H22 in, offering support and stability and enabling the possibility of raising it above ground level. The design is ideal for rough environments and demanding 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 179 lbs. However, its challenging mobility is solved by its wheel kit and its folding handle, which will ease its displacement, once it is on the floor.

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.

From a security point of view, the generator is equipped with an overload protection (circuit breaker) and an automatic low oil shut-off, giving you a peace of mind during use.

Besides the usual set of documentation and owner's manual (opens in a new tab) 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).

  • At a dry weight of 179 pounds, the Lifan ES5700 is one of the heavier devices which can produce between 4500 and 5500 running watts. If weight matters to you, one of the champions in this power range is the Genmax GM6000XiE with only 106.9 pounds.
  • As this generator has its lowest possible noise of 75 dBA, it should be considered noisier compared to its peers of a comparable running wattage. 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 ES5700, falls within the average autonomy range compared to generators of a roughly same power, with a run time of around 10 hours at a 50% load and a full tank. If autonomy is your priority, one of the devices of a similar power output with the highest run time is the Cat RP5500, reaching 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. In fact, this generator is not among the most fuel efficient, within the aforementioned wattage range : its estimated gasoline consumption at 50% load is around 0.65 GPH. If fuel consumption is your top priority, we suggest to check out the Genmax GM5500i, which has a fuel consumption of only 0.41 GPH and thus, is one of the most efficient devices in our database.

The bottom line

STRENGTHS:

The Lifan ES5700 doesn't have any specs that exceed those of other generators of its class.
