Zoom on the Lifan ES5700E
In a nutshell, the Lifan ES5700E is a portable generator mostly geared towards:
- RV travellers who wish to upgrade their experience to another level
- Homeowners who want to be sure of their ability to power their fridges, cooking tools, heating and lighting equipment during power failures
In the sections ahead, the power characteristics, availability of various outlets, the portability and any additional features of the device shall be discussed, including its emission compliance information.
Power & Run Time
The Lifan ES5700E's build contains a gasoline-fueled 389 cc (13 hp) Lifan OHV 4-stroke engine. With a 120V output, it gives a running wattage of 5000W and also a peak wattage of 5700W.
At a noise rating of 75 dBA (just slightly more noisy than a shower), this generator can be started via a simple traditional pull-start mechanism, or a simple and elegant electric starter (battery not included).
With a full tank, the ES5700E can operate for around 10 hours at 50% load (fuel consumption around 0.65 GPH), thanks to its fuel capacity of 6.5 gallons.
The control panel provides the upcoming 9 AC outlets:
This Lifan generator features an L5-30R receptacle, enabling an easy RV connection via an L5-30P to TT-30R adaptor. However, it is still not quite RV ready.
The Lifan ES5700E has a conventional, open frame design, of the following dimensions: L30 x W23 x H22 in, which offers support and allows it to be raised above ground level. The design is ideal for rough environments and demanding outdoor use.
As the generator's weight is 190 pounds, manually moving it or transporting it may be challenging, despite the fact that it is technically considered 'portable' (movable).
Thanks to a built-in fuel gauge, the generator allows you to quickly, conveniently and easily check the gas level at a glance.
Security-wise, this product benefits from an automatic low oil shut-off and an overload protection (circuit breaker), which gives you a complete peace of mind when using it.
Besides the usual set of documentation and owner's manual to get you promptly started, Lifan also included a tool kit in the ES5700E's packaging.
The Lifan ES5700E is EPA approved, but NOT CARB-compliant. Thus, it cannot be purchased or sold in California.
The Lifan ES5700E versus other generators
The following charts are provided to give you an idea of how some of the key specs of the Lifan ES5700E compare to generators of similar power (between 4500 and 5500 W).
- Since the generator weighs in at a dry weight of 190 lbs, the Lifan ES5700E belongs in the expected weight range for devices which can produce between 4500 and 5500 rated watts. If you are concerned by weight, one of the champions in the above mentioned power range is the Westinghouse WGen5300v, with a dry weight of just 107 pounds.
- If compared to generators capable of producing a similar running wattage, this generator with a lowest emitted noise of 75 dBA can be considered somewhat noisy. For those who are looking for a less noisy device, we suggest the Honda EU7000iS. With just 52 dBA, it is one of the most quiet devices in this power range.
- Regarding its autonomy, the autonomy of the ES5700E, reaching around 10 hours at a 50% load, can be considered as low end, compared to other products of a roughly equal output. Concerning the run times, one of the several devices with a comparable output, offering the highest autonomy, is the Cat RP5500, which is able to run for around 15 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. In fact, this generator is not among the most fuel efficient, within the aforementioned wattage range : its estimated gasoline consumption at 50% load is around 0.65 GPH. If fuel consumption is your top priority, we suggest to check out the Westinghouse WGen5300v, which has a fuel consumption of only 0.35 GPH and thus, is one of the most efficient devices in our database.
As you can see from this interactive chart, when compared to other 4500-5500W generators, the Lifan ES5700E is on the cheap side of the price range.
It can therefore be a really good buy if you're looking to acquire a budget generator.

Unlike many websites, we did our best to research each of the specs above. That being said, we are not immune to making the occasional mistake or omission. Should you notice any missing or incorrect values, don't hesitate to suggest improvements so we can address the issue.
LIFAN, or rather LIFAN Power USA, is a rather small and new company, based in Arizona. LIFAN’s range is comprised of engines and related products, such as pressure washers, water pumps and of course, generators – of which there is a surprising variety, including inverters, portable generators, but also high output, standby home generators. The company admirably admits that their primary (and most likely only) manufacturing facilities are located in China and their goal is to provide affordable products above all.
The Lifan ES5700E is covered under a warranty for up to 3 years. This warranty may be limited and may not cover all parts of the generator.
