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 who want to ensure that a power failure will not prevent them from working

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 is powered by a 212 cc (7 hp) Lifan OHV 4-stroke engine. It delivers 120/240V, runs on gasoline and offers a running wattage of 3500W as well as a peak wattage of 4000W.

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

The fuel capacity of 4 gallons allows the LF4000 to operate for around 12 hours at 50% load with a full tank (fuel consumption around 0.33 GPH).

Outlets

The control panel features the following 3 AC outlets:

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

In addition, it provides 2 DC outlets: there's a 12V 8A receptacle with which you may charge your batteries with ease and a 5V USB port allowing you to conveniently charge electronics such as mobile phones and tablets.

As the LF4000 holds a twist-lock L14-30R receptacle, it is transfer switch ready: you'll easily be able to connect it to your breaker box to power your home during a power outage.

Portability

The design of the Lifan LF4000 is a typical, open frame, with the dimensions of L25.5 x W19.3 x H19.3 in, offering support and stability and enabling the possibility of raising it above ground level. The generator is designed for ideal use outdoors and in rough environments.

Although this generator is technically considered 'portable' (in the sense that it can be moved), its 104 lbs make it incredibly difficult to manually lift and transport.

In addition, the device is equipped with a lift hook on the top of its frame, which provides extra safety during the loading, unloading and transport of the generator.

Features

Panel of the Lifan LF4000

The LF4000's control panel

To help you monitor the LF4000's status and activity, its control panel is equipped with a convenient meter showing you voltage, frequency and lifetime hours.

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 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 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. 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.
  • This generator has a somewhat average expected noise for its power range, rated at 65 dBA. 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.
  • Offering around 12 hours of running time on a full tank at 50% load, the LF4000 is 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 around 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. As this generator uses an estimated 0.33 GPH (gallon per hour) at a 50% load, it finds itself in the average gasoline consumption range of similar products. 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 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
  • Decent fuel efficiency
WEAKNESSES:
  • No electric start
  • Not CARB-compliant
  • No spark arrestor
