Description

Zoom on the Lifan LF4250EPL

In summary, the Lifan LF4250EPL is a compact portable generator especially useful for:

  • RV travellers looking for even more independence
  • Occasional participants of outdoor events, competitions, concerts and festivals
  • Amateur DIY lovers
  • Homeowners who want to be able to use the most necessary devices in their household, even during a blackout
  • Professionals who want to ensure that a power failure will not prevent them from working

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 LF4250EPL's design includes a gasoline-fueled 212 cc (7 hp) Lifan OHV 4-stroke engine. With a 120V output, it gives a running wattage of 3500W and also a peak wattage of 4250W.

With a noise rating of 65 dBA (just slightly more noisy than an office), the generator features a conventional pull-start mechanism, but also a simple and elegant 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).

Sensitive electronics can be safely plugged in the AC outlets, as the LF4250EPL produces a clean sine wave, with a <5% Total Harmonic Disruption (THD).

Outlets

The control panel includes the following 3 AC outlets:

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

It also sports 3 DC outlets: there's two 12V 8A receptacles 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.

Because the LF4250EPL is equipped with a twist-lock L14-30R receptacle, it is transfer switch ready: it can power your home during a power outage, as it can be easily connected to your breaker box to power your household.

Portability

The Lifan LF4250EPL 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 generator is designed for ideal use outdoors and in rough environments.

Even though this device may be technically portable (as in movable), manipulation and transportation without special equipment can be a challenge, as it weighs 104 pounds. Still, once it is on the ground, its wheel kit and its folding handle can easily solve the issue of low mobility and allow for easy relocation of the device.

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 LF4250EPL

The LF4250EPL's control panel

The control panel of the LF4250EPL includes a convenient meter showing you voltage, frequency and lifetime hours, helpful for the monitoring of its status and activity.

The fuel level of the generator can be determined quickly, easily, and conveniently with the help of its built-in fuel gauge.

From a security point of view, the generator is equipped with an automatic low oil shut-off and an overload protection (circuit breaker), giving you a peace of mind during use.

While the standard documentation and an owner's manual (opens in a new tab), helpful for starting the device promptly, come with the Lifan LF4250EPL, the following accessories are also included: battery charging cables and tool kit.

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).

  • With a dry weight of 104 pounds, the Lifan LF4250EPL finds itself in the expected weight range for generators able to produce between 3000 and 4000 rated watts. If you are concerned by weight, one of the champions in the above mentioned power range is the WEN GN400i, with a dry weight of just 66.1 pounds.
  • As this generator can emit noise as low as 65 dBA, it finds itself in the average expected noise for this kind of 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.
  • Given that the LF4250EPL reaches an autonomy of around 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 EB4000X, as it provides around 16 hours.
  • While the run time is an important parameter, it is dependent on the fuel tank’s capacity and thus, doesn’t say much on its own unless we consider fuel consumption as well. 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 you wish to acquire one of the most gasoline efficient products of this power range, the Westinghouse iGen4200, with a fuel consumption of 0.17 GPH could be in your good books.

Price comparison

As you can see from this interactive 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.
