Description

Zoom on the Lifan LF4250EPL

In summary, the Lifan LF4250EPL 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 be able to deliver results, even during a power failure

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 LF4250EPL houses a 212 cc (7 hp) Lifan OHV 4-stroke engine, which provides 120V, consumes gasoline and delivers a running wattage of 3500W along with a peak wattage of 4250W.

With a noise rating of 65 dBA (just slightly more noisy than an office), the generator features a simple traditional pull-start mechanism, but also a convenient and easy-to-use electric starter (battery not included).

Thanks to a fuel capacity of 4 gallons, the LF4250EPL can operate for around 12 hours at 50% load with a full tank (fuel consumption around 0.33 GPH).

The LF4250EPL produces a clean sine wave: thanks to a <5% Total Harmonic Disruption (THD), your sensitive electronics can be safely plugged in the AC outlets.

The following are examples of possible devices which the generator will allow you to power simultaneously:Note: All of these devices might not start simultaneously. Provided examples are based on a maximum load of 75 % and estimated wattages. With the help of our wattage calculator you can find out if this product suits your requirements.

Outlets

The control panel includes the following 3 AC outlets:

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

Furthermore, it has 3 DC outlets: there's two 12V 8A receptacles with which you may charge your batteries with ease and a 5V USB port with which charging of electronics like mobile phones and tablets is made convenient.

As the LF4250EPL 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

With its dimensions of L25.5 x W19.3 x H19.3 in, the conventional, open frame design of the Lifan LF4250EPL offers stability and allows 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. However, its challenging mobility is solved by a wheel kit and a folding handle, which will ease its displacement, once it is on the floor.

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.

The LF4250EPL's control panel

The LF4250EPL's control center features a convenient meter showing you voltage, frequency and lifetime hours to aid you with the monitoring of its status and activity.

The generator includes a built-in fuel gauge, a quick, easy and convenient method of checking the device’s gas level.

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.

Along the basic documentation and a user manual, useful for starting the generator right away, the Lifan LF4250EPL's package also includes these accessories: tool kit and battery charging cables.

Emissions

The Lifan LF4250EPL is EPA approved, but NOT CARB-compliant. Thus, it cannot be purchased or sold in California.

The Lifan LF4250EPL versus other generators

The following charts are provided to give you an idea of how some of the key specs of the Lifan LF4250EPL compare to generators of similar power (between 3000 and 4000 W).

  • At a weight of 104 pounds, the Lifan LF4250EPL places in the expected weight range of the generators in the 3000-4000 rated wattage range. Regarding dry weight, one of the champions in the same power range is the Generac GP3500iO, with a dry weight of only 74.3 lbs.
  • 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 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 12 hours of running time on a full tank at 50% load, the LF4250EPL is within the average autonomy range of similarly powerful generators. If concerned with autonomy, one of the products of a comparable power output, which offers the highest run time, is the Honda EB4000, boasting with 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 Standing at an estimated 0.33 GPH (gallon per hour) at a 50% load, this generator is somewhat average in this area compared to other devices, within the aforementioned wattage range. If not satisfied with the afore-mentioned fuel consumption, you may wish to check out the Westinghouse iGen4200. With a fuel consumption of as little as 0.17 GPH, it is one of the most efficient generators currently on the market.

Price comparison

As you can see from this dynamic chart, when compared to other 3000-4000W generators, the Lifan LF4250EPL is on the average side of the price range.

Therefore, this generator nicely fits in the expected budget for this kind of product.
