Zoom on the Lifan ES4100

In summary, the Lifan ES4100 is a compact portable generator especially useful for:

  • RV travellers wishing to enhance their freedom and nomad lifestyle
  • Occasional participants of outdoor events, competitions, concerts and festivals
  • DIYers who wish to improve their efficiency with tools
  • 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 ES4100 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 4100W.

With a noise rating of 65 dBA (just slightly more noisy than an office), the generator features a simple traditional pull-start mechanism.

With a fuel capacity of 4 gallons, the ES4100 may run for around 12 hours at 50% load with a full tank (fuel consumption around 0.33 GPH).

Outlets

The control panel features the upcoming 7 AC outlets:

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

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

Portability

With its dimensions of L23 x W13 x H15 in, the conventional, open frame design of the Lifan ES4100 offers stability and allows the generator to be raised above ground level. The featured design is ideal for the outdoors and all tough environments.

Since the generator weighs 104 lbs, it will be incredibly difficult to manually lift it and transport it, even though it is technically considered to 'be portable' (in the sense that it is movable).

Features

Panel of the Lifan ES4100

The ES4100'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 ES4100's packaging.

Emissions

The Lifan ES4100 is EPA approved, but NOT CARB-compliant. Thus, it cannot be purchased or sold in California.

The Lifan ES4100 versus other generators

The following charts are provided to give you an idea of how some of the key specs of the Lifan ES4100 compare to generators of similar power (between 3000 and 4000 W).

  • Having a dry weight of 104 lbs, the Lifan ES4100 belongs in the expected weight range for generators which produce 3000 to 4000 rated watts. Regarding dry weight, one of the champions in the same power range is the WEN GN400i, with a dry weight of only 66.1 lbs.
  • The generator can be considered average in its noise for its power category, as it is rated at 65 dBA. If you are concerned with noise, check out the Cat INV4000E, which is one of the least noisy generators in its power range, with a noise rating of just 51 dBA.
  • As the ES4100 offers around 12 hours run time on a full tank at a 50% load, it falls within the average autonomy range among the generators of a similar power. 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 EB4000X, with around 16 hours.
  • While the run time is an important parameter, it is dependent on the fuel tank’s capacity and thus, doesn’t say much on its own unless we consider fuel consumption as well. This generator reaches an estimated fuel consumption of 0.33 GPH (gallon per hour) at a 50% load, making it average, for the previously mentioned wattage range. If you wish to further improve in the area of fuel efficiency, the Westinghouse iGen4200, which boasts with a gas consumption of only 0.17 GPH, may be the right generator for you.

Price comparison

As you can see from this interactive chart, when compared to other 3000-4000W generators, the Lifan ES4100 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
AVERAGE SPECS:
  • Decent weight (104 lbs)
  • Acceptable noise (65 dBA)
