Description

LIFAN Power USA’s Energy Storm ES5700 is part of our Energy Storm Portable Generator Line. The unit is EPA Approved. This quality generator is a perfect fit for the emergencies, homeowners, job sites, special events, parties, or weddings! (source: Lifan)

Zoom on the Lifan ES5700

In a nutshell, the Lifan ES5700 is a portable generator mostly geared towards:

  • RV travellers looking for even more independence
  • 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 ES5700'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.

Enjoying a noise rating of 75 dBA (just slightly more noisy than a dishwasher), this generator gets running thanks to a conventional pull-start mechanism.

With a fuel capacity of 6.5 gallons, the ES5700 may run for around 10 hours at 50% load with a full tank (fuel consumption around 0.65 GPH).

Several examples of what the generator may allow you to power simultaneously are:Note: Not all of these items may be able to start at the same time. These examples are based on a maximum load of 75 % and on wattage estimates. Use our wattage calculator to find out if this product will be suitable for your needs.

Outlets

The control panel includes the following 9 AC outlets:

Duplexes 120V 20A (5-20R)
120V 30A (L5-30R) receptacle

While this Lifan generator is not RV Ready, its L5-30R receptacle can be used for a simple RV connection with an L5-30P to TT-30R adaptor.

Portability

The dimensions of the Lifan ES5700, which are L27 x W20 x H22 in, and its typical, open frame design provides stability and enables the generator to be raised above ground level. The featured design is ideal for the outdoors and all tough environments.

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 179 lbs. However, its challenging mobility is solved by a wheel kit and a folding handle, which will ease its displacement, once it is on the floor.

Features

The ES5700's control panel

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 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 user manual to get you promptly started, Lifan also included a tool kit in the ES5700's packaging.

Emissions

The Lifan ES5700 is EPA approved, but NOT CARB-compliant. Thus, it cannot be purchased or sold in California.

The Lifan ES5700 versus other generators

The following charts are provided to give you an idea of how some of the key specs of the Lifan ES5700 compare to generators of similar power (between 4500 and 5500 W).

  • Having a dry weight of 179 lbs, the Lifan ES5700 belongs in the expected weight range for generators which produce 4500 to 5500 rated watts. If weight is your top priority, one of the champions in this power category is the WEN 56500, weighing just 119 pounds.
  • This generator, with its lowest possible noise rated at 75 dBA falls into the more noisy category, compared to other devise of a similar running wattage. 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 ES5700, reaching 10 hours at a 50% load, can be considered as low end, compared to other products of a roughly equal output. Furthermore, considering the run times, one of the generators which have a roughly same power output, with the highest autonomy, is the Cat RP5500, as it provides 15 hours.
  • The run time is important, but also hugely depends on the capacity of the fuel tank and doesn't mean much if we don't talk about fuel consumption as well. This generator is somewhat less fuel efficient than devices of comparable output: its estimated fuel consumption reaches 0.65 GPH at a 50% load. If not satisfied with the afore-mentioned fuel consumption, you may wish to check out the Westinghouse WGen5500. With a fuel consumption of as little as 0.44 GPH, it is one of the most efficient generators currently on the market.

Price comparison

As you can see from this dynamic chart, when compared to other 4500-5500W generators, the Lifan ES5700 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.
