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 a nutshell, the Lifan ES8100E is a portable generator mostly geared towards:

  • Food truck owners who do not wish to see their business interrupted under any circumstances
  • RV travellers who wish to upgrade their experience to another level

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 ES8100E's core is the 420 cc (15 hp) Lifan OHV 4-stroke engine, which runs on gasoline. With an output of 120/240V, it provides a running wattage of 7500W and a peak wattage of 8100W.

With a noise rating of 75 dBA (just slightly more noisy than a shower), the generator features a conventional pull-start mechanism, but also a convenient and easy-to-use electric starter (battery not included).

With a fuel capacity of 6.5 gallons, the ES8100E may run for around 8 hours at 50% load with a full tank (fuel consumption around 0.81 GPH).

Outlets

The control panel includes the following 8 AC outlets:

Three Duplexes 120V 20A (5-20R)
120V 30A (L5-30R) receptacle
120/240V 30A (L14-30R) 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. Besides, as it features a twist-lock L14-30R receptacle, the ES8100E 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

With its dimensions of L27 x W20 x H21 in, the conventional, open frame design of the Lifan ES8100E offers stability and allows the generator to be raised above ground level. The device has been designed for tough environments and demanding outdoor use.

Although this generator is technically considered 'portable' (in the sense that it can be moved), its 190 lbs make it incredibly difficult to manually lift and transport. 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

Panel of the Lifan ES8100E

The ES8100E's control panel

A built-in fuel gauge allows for a quick, easy and convenient check of the fuel level of the generator.

From a security point of view, the generator is equipped with an overload protection (circuit breaker) and an automatic low oil shut-off, giving you a peace of mind during use.

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 far as its dry weight is concerned, the Lifan ES8100E weighs just 190 pounds and thus, it is one of the lighter 7000 to 8000 rated wattage generators. If you are concerned by weight, one of the champions in the above mentioned power range is the Sportsman GEN85KIDF, with a dry weight of just 133 pounds.
  • Since the generator's noise is rated at 75 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 A-iPower SUA8000iSF, whose lowest noise levels reach just 65 dBA.
  • Regarding its autonomy, the autonomy of the ES8100E, reaching around 8 hours at a 50% load, can be considered as low end, compared to other products of a roughly equal output. If autonomy is your priority, one of the devices of a similar power output with the highest run time is the A-iPower SUA8000iSF, reaching around 13 hours.
  • Autonomy holds its importance, however, it is largely dependent on the generator’s fuel capacity and so, it is nonsensible to discuss it without mentioning fuel efficiency as well. Compared to its peers, this generator is not exactly fuel efficient, compared to similarly powerful devices, with an estimated fuel consumption of 0.81 GPH at a 50% load. If you wish to further improve in the area of fuel efficiency, the A-iPower SUA8000iSF, which boasts with a gas consumption of only 0.52 GPH, may be the right generator for you.

Price comparison

As you can see from this interactive chart, when compared to other 7000-8000W generators, the Lifan ES8100E 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.

The bottom line
