Description

For maximum conductivity, the Platinum Portable Generators use 100% copper windings and welded magnetic plates to produce clean, dependable energy. These commercial grade generators are a perfect fit for the farm, contractors, emergencies, homeowners, job sites, or special events! (source: Lifan (opens in a new tab))

Zoom on the Lifan LF4250EPL

In a nutshell, the Lifan LF4250EPL is a compact portable generator mostly geared towards:

  • RV travellers who wish to upgrade their experience to another level
  • Occasional participants of outdoor events, competitions, concerts and festivals
  • 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 in need of safely powering high-intensity work or lighting equipment

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 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.

At a noise rating of 65 dBA (just slightly more noisy than an office), this generator can be started via a simple traditional pull-start mechanism, or a simple and elegant electric starter (battery not included).

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

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.

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.

Since the LF4250EPL 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 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 design is ideal for rough environments and demanding outdoor use.

As the generator's weight is 104 pounds, manually moving it or transporting it may be challenging, despite the fact that it is technically considered 'portable' (movable). However, its challenging mobility is solved by its wheel kit and its folding handle, which will ease its displacement, once it is on the floor.

The generator comes with an additional safety feature, a lift hook on the top of its frame, which is helpful during its transport, loading and unloading.

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.

Security-wise, this product benefits from an overload protection (circuit breaker) and an automatic low oil shut-off, which gives you a complete peace of mind when using it.

Apart from the typical documentation and an owner's manual (opens in a new tab), which lets you start it right away, the Lifan LF4250EPL also is packed along with the following accessories: 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. 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.
  • The generator can be considered average in its noise for its power category, as it is rated at 65 dBA. If you are concerned with noise, check out the Cat INV4000E, which is one of the least noisy generators in its power range, with a noise rating of just 51 dBA.
  • The LF4250EPL, offering a run time of around 12 hours with a full tank at a 50% load, falls within the average autonomy range when compared to its peers. If concerned with autonomy, one of the products of a comparable power output, which offers the highest run time, is the Honda EB4000X, boasting with 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. 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 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.
