Description

Zoom on the Lifan ES4100E

In summary, the Lifan ES4100E is a portable generator especially useful for:

  • RV travellers who wish to upgrade their experience to another level
  • Occasional participants of outdoor events, competitions, concerts and festivals
  • Amateur DIY lovers
  • Homeowners in need of an emergency backup power for their essentials

The following sections will present you in detail its power characteristics, the different outlets it offers, its overall portability, the extra features it benefits from, and any relevant emission compliance details.

Power & Run Time

The Lifan ES4100E's engine, 212 cc (7 hp) Lifan OHV 4-stroke, fueled by gasoline, can deliver 120V. It provides a running wattage of 3500W and reaches a peak wattage of 4000W.

The generator is rated for a noise of 65 dBA (just slightly more noisy than background music). Its starting mechanisms include a simple traditional pull-start mechanism and a simple and elegant electric starter (battery not included).

With a fuel capacity of 4 gallons, the ES4100E may run 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

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 ES4100E has the following dimensions: L25 x W20 x H24 in. In combination with its conventional, open frame design, they provide support and allow the generator to be raised above ground level. The featured design is ideal for the outdoors and all tough environments.

Even though this device may be technically portable (as in movable), manipulation and transportation without special equipment can be a challenge, as it weighs 118 pounds. 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 ES4100E

The ES4100E's control panel

A built-in fuel gauge allows for a quick, easy and convenient check of the fuel level of the generator.

As for its security measures, the device features an automatic low oil shut-off and an overload protection (circuit breaker), letting you use it with a peace of mind.

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 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).

  • At a weight of 118 pounds, the Lifan ES4100E places in the expected weight range of the generators in the 3000-4000 rated wattage range. In terms of weight, one of the champions in their power range is the Genmax GM3300i, standing at just 47.4 lbs.
  • This generator has a somewhat average expected noise for its power range, rated at 65 dBA. For those who are looking for a less noisy device, we suggest the Cat INV4000E. With just 51 dBA, it is one of the most quiet devices in this power range.
  • 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 concerned with autonomy, one of the products of a comparable power output, which offers the highest run time, is the Predator 4375, boasting with around 16 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 has an average fuel consumption among comparably powerful devices, as it reaches 0.33 GPH (gallon per hour) at a 50% load. If fuel consumption is your top priority, we suggest to check out the Westinghouse iGen4200, which has a fuel consumption of only 0.17 GPH and thus, is one of the most efficient devices in our database.

Price comparison

As you can see from this interactive 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.
