Description
Zoom on the Lifan LF4000
In a nutshell, the Lifan LF4000 is a compact portable generator mostly geared towards:
- 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 in need of safely powering high-intensity work or lighting equipment
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's design includes a gasoline-fueled 212 cc (7 hp) Lifan OHV 4-stroke engine. With a 120/240V output, it gives a running wattage of 3500W and also 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 an office).
The LF4000 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.
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 allowing you to conveniently charge electronics such as mobile phones and tablets.
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 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 featured design is ideal for the outdoors and all tough environments.
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).
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
To help you monitor the LF4000's status and activity, its control panel is equipped with a convenient meter, which displays 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 automatic low oil shut-off and an overload protection (circuit breaker), 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).
- Since the generator weighs in at a dry weight of 104 lbs, the Lifan LF4000 belongs in the expected weight range for devices which can 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 noise emissions are important to you, one of the least noisy generators of this power range is the Cat INV4000E with only 51 dBA.
- The LF4000, falls within the average autonomy range compared to generators of a roughly same power, with a run time of around 12 hours at a 50% load and a full tank. If autonomy is your priority, one of the devices of a similar power output with the highest run time is the Predator 4375, reaching 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. 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 not satisfied with the afore-mentioned fuel consumption, you may wish to check out the Westinghouse iGen4200. With a fuel consumption of as little as 0.17 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 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
