Description
Zoom on the Lifan LF4000
In summary, the Lifan LF4000 is a compact portable generator especially useful for:
- RV travellers wishing to enhance their freedom and nomad lifestyle
- Occasional participants of outdoor events, competitions, concerts and festivals
- DIYers who wish to improve their efficiency with tools
- Homeowners in need of an emergency backup power for their essentials
- Professionals who want to ensure that a power failure will not prevent them from working
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 LF4000 houses a 212 cc (7 hp) Lifan OHV 4-stroke engine, which provides 120/240V, consumes gasoline and delivers a running wattage of 3500W along with a peak wattage of 4000W.
The generator features a conventional pull-start mechanism. It is rated for a noise of 65 dBA (just slightly more noisy than a normal conversation).
The fuel capacity of 4 gallons allows the LF4000 to operate for around 12 hours at 50% load with a full tank (fuel consumption around 0.33 GPH).
Outlets
The control panel features the following 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 you may charge electronics, for example mobile phones or tablets, conveniently.
As it features a twist-lock L14-30R receptacle, the LF4000 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 LF4000 has a conventional, open frame design, of the following dimensions: L25.5 x W19.3 x H19.3 in, which offers support and allows it to be raised above ground level. This type of design is ideal for tough environments and heavy outdoor use.
Since the generator weighs 104 lbs, it will be incredibly difficult to manually lift it and transport it, even though it is technically considered to 'be portable' (in the sense that it is movable).
A lift hook, which is on the top of the frame, serves as an extra safety feature for the transport, unloading and loading of the device.
Features
The LF4000's control panel
The control panel of the LF4000 includes a convenient meter showing you voltage, frequency and lifetime hours, helpful for 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.
As far as security is concerned, the generator can be used with a peace of mind, as it features an overload protection (circuit breaker) and an automatic low oil shut-off.
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).
- At a weight of 104 pounds, the Lifan LF4000 places in the expected weight range of the generators in the 3000-4000 rated wattage range. If weight is your top priority, one of the champions in this power category is the WEN GN400i, weighing just 66.1 pounds.
- 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’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.
- As the LF4000 offers around 12 hours run time on a full tank at a 50% load, it falls within the average autonomy range among the generators of a similar power. Concerning the run times, one of the several devices with a comparable output, offering the highest autonomy, is the Honda EB4000X, which is able to run for around 16 hours.
- Run times are important, yet thanks to their dependence on the fuel capacity, they should be judged along with the fuel consumption of the device. 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 further improve in the area of fuel efficiency, the Westinghouse iGen4200, which boasts with a gas consumption of only 0.17 GPH, may be the right generator for you.
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
