Description

Zoom on the Lifan LF4000

In a nutshell, the Lifan LF4000 is a compact portable generator mostly geared towards:

  • RV travellers who wish to upgrade their experience to another level
  • People occasionally participating in outdoor fairs, festivals or events
  • 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
  • Professionals who want to be able to deliver results, even during a power failure

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 LF4000's engine, 212 cc (7 hp) Lifan OHV 4-stroke, fueled by gasoline, can deliver 120/240V. It provides a running wattage of 3500W and reaches a peak wattage of 4000W.

The generator features a simple traditional pull-start mechanism. It is rated for a noise of 65 dBA (just slightly more noisy than background music).

With a fuel capacity of 4 gallons, the LF4000 may run for around 12 hours at 50% load with a full tank (fuel consumption around 0.33 GPH).

Outlets

The control panel provides the upcoming 3 AC outlets:

Duplex 120V 20A (5-20R) GFCI
120/240V 30A (L14-30R) receptacle

It also sports 2 DC outlets: there's a 12V 8A receptacle with which you may charge your batteries with ease and a 5V USB port with which you may charge electronics, for example mobile phones or tablets, conveniently.

Since the LF4000 bears a twist-lock L14-30R receptacle, it is transfer switch ready: it is easily connectible to a breaker box and can power your home in case of a power outage.

Portability

The Lifan LF4000 has the following dimensions: L25.5 x W19.3 x H19.3 in. In combination with its conventional, open frame design, they provide support and allow the generator to be raised above ground level. The device has been designed for tough 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 104 lbs.

A lift hook, which is on the top of the frame, serves as an extra safety feature for the transport, unloading and loading of the device.

Features

Panel of the Lifan LF4000

The LF4000's control panel

The LF4000's control center features a convenient meter, which displays voltage, frequency and lifetime hours to aid you with the monitoring of its status and activity.

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 standpoint, the product offers an automatic low oil shut-off and an overload protection (circuit breaker), allowing you to 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 LF4000's packaging.

Emissions

The Lifan LF4000 is EPA approved, but NOT CARB-compliant. Thus, it cannot be purchased or sold in California.

The Lifan LF4000 versus other generators

The following charts are provided to give you an idea of how some of the key specs of the Lifan LF4000 compare to generators of similar power (between 3000 and 4000 W).

  • At a weight of 104 pounds, the Lifan LF4000 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 WEN GN400i, standing at just 66.1 lbs.
  • 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 you’d prefer a less noisy device, one of the most quiet devices, which share the same power range with this one, is the Cat INV4000E, whose lowest noise levels reach just 51 dBA.
  • As the LF4000 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. Concerning the run times, one of the several devices with a comparable output, offering the highest autonomy, is the Honda EB4000X, which is able to run for around 16 hours.
  • Even though run times are undoubtedly important, they are dependent on the fuel capacity to a large extent. For a more wholesome picture, we must take into consideration the fuel consumption of the generator. 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 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 interactive chart, when compared to other 3000-4000W generators, the Lifan LF4000 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
