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
  • DIYers who wish to improve their efficiency with tools
  • 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 features a simple traditional pull-start mechanism and also a convenient and easy-to-use electric starter (battery not included). It is rated for a noise of 65 dBA (just slightly more noisy than background music).

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

The generator will allow you to simultaneously power various devices, for example:Note: Not all of these items may be able to start at the same time. These examples are based on a maximum load of 75 % and on wattage estimates. Use our wattage calculator to find out if this product will be suitable for your needs.

Outlets

The control panel provides the upcoming 7 AC outlets:

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

This Lifan generator isn't quite RV Ready, but it features an L5-30R receptacle, allowing a simple RV connection through 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. This type of design is ideal for tough environments and heavy outdoor use.

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. 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

The ES4100E's control panel

Thanks to a built-in fuel gauge, the generator allows you to quickly, conveniently and easily check the gas level at a glance.

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

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).

  • Since the generator weighs in at a dry weight of 118 lbs, the Lifan ES4100E belongs in the expected weight range for devices which can produce between 3000 and 4000 rated watts. If weight is your top priority, one of the champions in this power category is the Generac GP3500iO, weighing just 74.3 pounds.
  • Since the generator's noise is rated at 65 dBA, it has the roughly average expected noise for a device of similar power. 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 Westinghouse iGen4500, whose lowest noise levels reach just 52 dBA.
  • Offering 12 hours of running time on a full tank at 50% load, the ES4100E is within the average autonomy range of similarly powerful generators. 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 16 hours .
  • Run times are important, yet thanks to their dependence on the fuel capacity, they should be judged along with the fuel consumption of the device. 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 are concerned with gasoline efficiency, having a fuel consumption of just 0.17 GPH, the Westinghouse iGen4200 is a device you should look out for.

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.
