Description

Zoom on the Lifan LF4000

In summary, the Lifan LF4000 is a compact portable generator especially useful for:

  • RV travellers wishing to enhance their freedom and nomad lifestyle
  • Handcrafting enthusiasts who wish to work on-the-go
  • Homeowners who want to be sure of their ability to power their fridges, cooking tools, heating and lighting equipment during power failures
  • Professionals in need of safely powering high-intensity work or lighting equipment

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 LF4000 houses a 212 cc (7 hp) Lifan OHV 4-stroke engine, which provides 120/240V, consumes gasoline and delivers a running wattage of 3500W along with 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 an office).

Thanks to a fuel capacity of 4 gallons, the LF4000 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: The above mentioned examples presume a maximum load of 75% and use wattage estimates. In addition, the items might not be able to start simultaneously. With our wattage calculator, you can predict if the product can fulfill your requirements.

Outlets

The control panel features the upcoming 3 AC outlets:

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

Furthermore, it has 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.

As it features a twist-lock L14-30R receptacle, the LF4000 is transfer switch ready: in case of a power outage, you will be easily able to connect it to a breaker box and power your household.

Portability

The dimensions of the Lifan LF4000, which are L25.5 x W19.3 x H19.3 in, and its typical, open frame design provides stability and enables the generator to be raised above ground level. The design is ideal for rough 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 located on the top of the frame offers an additional safety feature while facilitating the transport, loading and unloading of the generator.

Features

The LF4000's control panel

The control panel of the LF4000 includes a convenient meter showing you voltage, frequency and lifetime hours, helpful for the monitoring of its status and activity.

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

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 user manual 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).

  • Since the generator weighs in at a dry weight of 104 lbs, the Lifan LF4000 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.
  • 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 are concerned with noise, check out the Westinghouse iGen4500, which is one of the least noisy generators in its power range, with a noise rating of just 52 dBA.
  • Given that the LF4000 reaches an autonomy of 12 hours with a full tank and at 50% load, it is placed within the average autonomy range of similarly powerful generators. Furthermore, considering the run times, one of the generators which have a roughly same power output, with the highest autonomy, is the Honda EB4000, as it provides 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 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 dynamic 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

STRENGTHS:
  • In the expected price range
AVERAGE SPECS:
  • Decent weight (104 lbs)
  • Acceptable noise (65 dBA)
  • Decent run time
