Description

LIFAN Power USA’s Energy Storm ES4100 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 ES4100

In summary, the Lifan ES4100 is a compact portable generator especially useful for:

  • RV travellers wishing to enhance their freedom and nomad lifestyle
  • Amateur DIY lovers
  • Homeowners who want to be able to use the most necessary devices in their household, even during a blackout

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 ES4100 is powered by a 212 cc (7 hp) Lifan OHV 4-stroke engine. It delivers 120V, runs on gasoline and offers a running wattage of 3500W as well as a peak wattage of 4100W.

At a noise rating of 65 dBA (just slightly more noisy than background music), the generator offers the possibility to start the device via a simple traditional pull-start mechanism.

With a full tank, the ES4100 can operate for around 12 hours at 50% load (fuel consumption around 0.33 GPH), thanks to its fuel capacity of 4 gallons.

The following are examples of possible devices which the generator will allow you to power simultaneously:Note: The above mentioned examples presume a maximum load of 75% and use wattage estimates. In addition, the items might not be able to start simultaneously. With our wattage calculator, you can predict if the product can fulfill your requirements.

Outlets

The control panel features the upcoming 7 AC outlets:

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

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.

Portability

The Lifan ES4100 has the following dimensions: L23 x W13 x H15 in. In combination with its conventional, open frame design, they provide support and allow the generator to be raised above ground level. This type of design is ideal for tough environments and heavy outdoor use.

Although this generator is technically considered 'portable' (in the sense that it can be moved), its 104 lbs make it incredibly difficult to manually lift and transport.

Features

Panel of the Lifan ES4100

The ES4100's control panel

Thanks to a built-in fuel gauge, the generator allows you to quickly, conveniently and easily check the gas level at a glance.

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 user manual to get you promptly started, Lifan also included a tool kit in the ES4100's packaging.

Emissions

The Lifan ES4100 is EPA approved, but NOT CARB-compliant. Thus, it cannot be purchased or sold in California.

The Lifan ES4100 versus other generators

The following charts are provided to give you an idea of how some of the key specs of the Lifan ES4100 compare to generators of similar power (between 3000 and 4000 W).

  • As its weight is 104 pounds, the Lifan ES4100 falls in the expected weight range of the devices in the 3000-4000 rated wattage category. In terms of weight, one of the champions in their power range is the Generac GP3500iO, standing at just 74.3 lbs.
  • This generator has a somewhat average expected noise for its power range, rated at 65 dBA. If noise emissions are one of your priorities, you may be interested in the Westinghouse iGen4500, one of the least noisy generators similarly powerful as this one, rated for 52 dBA.
  • Offering 12 hours of running time on a full tank at 50% load, the ES4100 is within the average autonomy range of similarly powerful generators. If autonomy is your priority, one of the devices of a similar power output with the highest run time is the Honda EB4000, reaching 16 hours.
  • While the run time is an important parameter, it is dependent on the fuel tank’s capacity and thus, doesn’t say much on its own unless we consider fuel consumption as well. This generator has an estimated fuel consumption of roughly 0.33 GPH (gallon per hour) at a 50% load, rendering it somewhat average compared to devices of a similar output. If you wish to further improve in the area of fuel efficiency, the Westinghouse iGen4200, which boasts with a gas consumption of only 0.17 GPH, may be the right generator for you.

Price comparison

As you can see from this dynamic chart, when compared to other 3000-4000W generators, the Lifan ES4100 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.
