Description

Zoom on the Lifan ES4100E

In a nutshell, the Lifan ES4100E is a portable generator mostly geared towards:

  • RV travellers wishing to enhance their freedom and nomad lifestyle
  • Amateur DIY lovers
  • Homeowners who want to be sure of their ability to power their fridges, cooking tools, heating and lighting equipment during power failures

In the sections ahead, the power characteristics, availability of various outlets, the portability and any additional features of the device shall be discussed, including its emission compliance information.

Power & Run Time

The Lifan ES4100E is powered by a 212 cc (7 hp) Lifan OHV 4-stroke engine. It delivers 120V, runs on gasoline and offers a running wattage of 3500W as well as a peak wattage of 4000W.

With a noise rating of 65 dBA (just slightly more noisy than background music), the generator features a conventional pull-start mechanism, but also a convenient and easy-to-use electric starter (battery not included).

The fuel capacity of 4 gallons allows the ES4100E to operate for around 12 hours at 50% load with a full tank (fuel consumption around 0.33 GPH).

Outlets

The control panel includes the following 7 AC outlets:

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

Even though this Lifan generator isn't quite RV Ready, its L5-30R receptacle allows an easy RV connection via an L5-30P to TT-30R adaptor.

Portability

The design of the Lifan ES4100E is a typical, open frame, with the dimensions of L25 x W20 x H24 in, offering support and stability and enabling the possibility of raising it above ground level. The generator is designed for ideal use outdoors and in rough environments.

As the generator's weight is 118 pounds, manually moving it or transporting it may be challenging, despite the fact that it is technically considered 'portable' (movable). However, its challenging mobility is solved by a wheel kit and a folding handle, which will ease its displacement, once it is on the floor.

Features

The ES4100E's control panel

The fuel level of the generator can be determined quickly, easily, and conveniently with the help of its built-in fuel gauge.

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 user manual to get you promptly started, Lifan also included a tool kit in the ES4100E's packaging.

Emissions

The Lifan ES4100E is EPA approved, but NOT CARB-compliant. Thus, it cannot be purchased or sold in California.

The Lifan ES4100E versus other generators

The following charts are provided to give you an idea of how some of the key specs of the Lifan ES4100E compare to generators of similar power (between 3000 and 4000 W).

  • With a dry weight of 118 pounds, the Lifan ES4100E finds itself in the expected weight range for generators able to produce between 3000 and 4000 rated watts. If weight is your top priority, one of the champions in this power category is the WEN GN400i, weighing just 66.1 pounds.
  • Because this generator emits noise as low as 65 dBA, it can be considered to have a pretty average expected noise rating for a device of its power. If noise emissions are one of your priorities, you may be interested in the Westinghouse iGen4500, one of the least noisy generators similarly powerful as this one, rated for 52 dBA.
  • The ES4100E, offering a run time of around 12 hours with a full tank at a 50% load, falls within the average autonomy range when compared to its peers. 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 Honda EB4000, with around 16 hours .
  • The run time is important, but also hugely depends on the capacity of the fuel tank and doesn't mean much if we don't talk about fuel consumption as well. This generator has an estimated fuel consumption of roughly 0.33 GPH (gallon per hour) at a 50% load, rendering it somewhat average compared to devices of a similar output. If you wish to acquire one of the most gasoline efficient products of this power range, the Westinghouse iGen4200, with a fuel consumption of 0.17 GPH could be in your good books.

Price comparison

As you can see from this dynamic chart, when compared to other 3000-4000W generators, the Lifan ES4100E is on the average side of the price range.

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

The bottom line

STRENGTHS:
  • In the expected price range
  • Electric start
AVERAGE SPECS:
