Description
Zoom on the Lifan LF4000
In summary, the Lifan LF4000 is a compact portable generator especially useful for:
- RV travellers who wish to upgrade their experience to another level
- People occasionally participating in sporting competitions, open-air performances and outdoor festivals
- Handcrafting enthusiasts who wish to work on-the-go
- 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 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's core is the 212 cc (7 hp) Lifan OHV 4-stroke engine, which runs on gasoline. With an output of 120/240V, it provides a running wattage of 3500W and a peak wattage of 4000W.
The generator is rated for a noise of 65 dBA (just slightly more noisy than background music). Its starting mechanism is based on a conventional pull-start mechanism.
With a fuel capacity of 4 gallons, the LF4000 may run for around 12 hours at 50% load with a full tank (fuel consumption around 0.33 GPH).
Outlets
The control panel provides the upcoming 3 AC outlets:
It also sports 2 DC outlets: there's a 12V 8A receptacle allowing you to easily charge your batteries and a 5V USB port with which charging of electronics like mobile phones and tablets is made convenient.
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. This type of design is ideal for tough environments and heavy 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).
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
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.
The generator allows for a quick, easy and convenient assessment of its gas level, as it is equipped with a built-in fuel gauge.
From a security standpoint, the product offers an overload protection (circuit breaker) and an automatic low oil shut-off, allowing you to use it with a peace of mind.
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 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).
- Having a dry weight of 104 lbs, the Lifan LF4000 belongs in the expected weight range for generators which produce 3000 to 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 noise emissions are important to you, one of the least noisy generators of this power range is the Cat INV4000E with only 51 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. If autonomy is your priority, one of the devices of a similar power output with the highest run time is the Honda EB4000X, reaching around 16 hours.
- Autonomy holds its importance, however, it is largely dependent on the generator’s fuel capacity and so, it is nonsensible to discuss it without mentioning fuel efficiency as well. This generator has an average fuel consumption among comparably powerful devices, as it reaches 0.33 GPH (gallon per hour) at a 50% load. If you are concerned with gasoline efficiency, having a fuel consumption of just 0.17 GPH, the Westinghouse iGen4200 is a device you should look out for.
Price comparison
As you can see from this interactive 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
- In the expected price range
- GFCI Outlets
- Decent weight (104 lbs)
- Acceptable noise (65 dBA)
- Decent run time
- Decent fuel efficiency
- No electric start
- Not CARB-compliant
- No spark arrestor
