Description

Zoom on the Lifan LF7250

In summary, the Lifan LF7250 is a compact portable generator especially useful for:

  • Food truck owners who do not wish to see their business interrupted under any circumstances
  • Homeowners who want to be able to use the most necessary devices in their household, even during a blackout
  • Professionals who want to be able to deliver results, even during a power failure
  • RV travellers looking for even more independence

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 LF7250's engine, 389 cc (13 hp) Lifan OHV 4-stroke, fueled by gasoline, can deliver 120/240V. It provides a running wattage of 6500W and reaches a peak wattage of 7250W.

The generator features a simple traditional pull-start mechanism. It is rated for a noise of 75 dBA (just slightly more noisy than a vacuum cleaner).

The LF7250 can operate for around 12 hours at 50% load with a full tank (fuel consumption around 0.63 GPH), due to its fuel capacity of 7.5 gallons.

Outlets

The control panel includes the following 6 AC outlets:

Two Duplexes 120V 20A (5-20R) GFCI
120V 30A (L5-30R) receptacle
120/240V 30A (L14-30R) receptacle

Furthermore, it has 2 DC outlets: there's a 12V 8A receptacle with which charging your batteries is made easy and a 5V USB port with which charging of electronics like mobile phones and tablets is made convenient.

Even if this Lifan generator isn't quite RV Ready, it still allows for an easy RV connection via an L5-30P to TT-30R adaptor, thanks to its L5-30R receptacle. Besides, as it features a twist-lock L14-30R receptacle, the LF7250 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 Lifan LF7250 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. This type of design is ideal for tough environments and heavy 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 140 lbs. Nevertheless, it can still be moved quite conveniently with the help of its wheel kit and its folding handle, once it is placed on the ground.

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

To help you monitor the LF7250's status and activity, its control panel is equipped with a convenient meter showing you voltage, frequency and lifetime hours.

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

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.

Besides the usual set of documentation and owner's manual (opens in a new tab) to get you promptly started, Lifan also included a tool kit in the LF7250's packaging.

Emissions

The Lifan LF7250 is EPA approved, but NOT CARB-compliant. Thus, it cannot be purchased or sold in California.

The Lifan LF7250 versus other generators

The following charts are provided to give you an idea of how some of the key specs of the Lifan LF7250 compare to generators of similar power (between 6000 and 7000 W).

  • In terms of its dry weight, the Lifan LF7250 stands at only 140 lbs, meaning that is one of the lighter devices of the 6000-7000 rated wattage category Regarding dry weight, one of the champions in the same power range is the Sportsman GEN85KIDF, with a dry weight of only 133 lbs.
  • As this generator can emit noise as low as 75 dBA, it finds itself in the average expected noise for this kind of power. For those who are looking for a less noisy device, we suggest the Powerhorse 7500i. With just 55 dBA, it is one of the most quiet devices in this power range.
  • With a run time of around 12 hours at 50% load, the LF7250 has one of the higher run times, compared to its similarly powerful peers. If concerned with autonomy, one of the products of a comparable power output, which offers the highest run time, is the Generac XC6500, boasting with around 14 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. This generator has an estimated fuel consumption of roughly 0.63 GPH (gallon per hour) at a 50% load, rendering it somewhat average compared to devices of a similar output. If not satisfied with the afore-mentioned fuel consumption, you may wish to check out the Lifan ESI 7000iER-EFI. With a fuel consumption of as little as 0.38 GPH, it is one of the most efficient generators currently on the market.

Price comparison

As you can see from this interactive chart, when compared to other 6000-7000W generators, the Lifan LF7250 is on the average side of the price range.

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