Description

LIFAN Power USA’s Energy Storm ES8100-E 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 (opens in a new tab))

Zoom on the Lifan ES8100E

In summary, the Lifan ES8100E is a portable generator especially useful for:

  • Food van owners who know that just a short power outage could lose them hundreds of dollars
  • Homeowners in need of an emergency backup power for their essentials
  • RV travellers looking for even more independence

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 ES8100E houses a 420 cc (15 hp) Lifan OHV 4-stroke engine, which provides 120/240V, consumes gasoline and delivers a running wattage of 7500W along with a peak wattage of 8100W.

Enjoying a noise rating of 75 dBA (just slightly more noisy than a shower), this generator can be started thanks to a simple traditional pull-start mechanism, but also to a simple and elegant electric starter (battery not included).

Thanks to a fuel capacity of 6.5 gallons, the ES8100E can operate for around 8 hours at 50% load with a full tank (fuel consumption around 0.81 GPH).

Outlets

The control panel features the upcoming 8 AC outlets:

Three Duplexes 120V 20A (5-20R)
120V 30A (L5-30R) receptacle
120/240V 30A (L14-30R) receptacle

Even though this Lifan generator isn't quite RV Ready, its L5-30R receptacle allows an easy RV connection via an L5-30P to TT-30R adaptor. Besides, since the ES8100E bears a twist-lock L14-30R receptacle, it is transfer switch ready: it is easily connectible to a breaker box and can power your home in case of a power outage.

Portability

The design of the Lifan ES8100E is a typical, open frame, with the dimensions of L27 x W20 x H21 in, offering support and stability and enabling the possibility of raising it above ground level. The generator is designed for ideal use outdoors and in rough environments.

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). Nevertheless, it can still be moved quite conveniently with the help of its wheel kit and its folding handle, once it is placed on the ground.

Features

The fuel level of the generator can be determined quickly, easily, and conveniently with the help of its built-in fuel gauge.

As for its security measures, the device features an overload protection (circuit breaker) and an automatic low oil shut-off, letting you 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 ES8100E's packaging.

Emissions

The Lifan ES8100E is EPA approved, but NOT CARB-compliant. Thus, it cannot be purchased or sold in California.

The Lifan ES8100E versus other generators

The following charts are provided to give you an idea of how some of the key specs of the Lifan ES8100E compare to generators of similar power (between 7000 and 8000 W).

  • As its weight is 190 pounds, the Lifan ES8100E falls in the expected weight range of the devices in the 7000-8000 rated wattage category. If weight matters to you, one of the champions in this power range is the Sportsman GEN85KIDF with only 133 pounds.
  • Because this generator emits noise as low as 75 dBA, it can be considered to have a pretty average expected noise rating for a device of its power. If noise emissions are one of your priorities, you may be interested in the A-iPower SUA8000iSF, one of the least noisy generators similarly powerful as this one, rated for 65 dBA.
  • As for its autonomy, the ES8100E, with an autonomy of around 8 hours at a 50% load, is placed on the low end among the generators of its kind. Furthermore, considering the run times, one of the generators which have a roughly same power output, with the highest autonomy, is the Predator 9000, as it provides around 13 hours.
  • Even though run times are undoubtedly important, they are dependent on the fuel capacity to a large extent. For a more wholesome picture, we must take into consideration the fuel consumption of the generator. This generator is not fuel efficient compared to devices of similar output: its estimated fuel consumption stands at 0.81 GPH at a 50% load. If fuel consumption is your top priority, we suggest to check out the A-iPower SUA8000iSF, which has a fuel consumption of only 0.52 GPH and thus, is one of the most efficient devices in our database.

Price comparison

As you can see from this interactive chart, when compared to other 7000-8000W generators, the Lifan ES8100E is on the average side of the price range.

Therefore, this generator nicely fits in the expected budget for this kind of product.
