Description

Generac’s Rapid Start portable generators with PowerDial, provides back up power with the turn of a dial. The PowerDial streamlines the start-up process by putting all the controls on one convenient dial, so no more separate switches for turning on the engine, opening the fuel valve, or to adjust the choke.

Zoom on the Generac RS8000E

In a nutshell, the Generac RS8000E is a portable generator mostly geared towards:

  • Food van owners who know that just a short power outage could lose them hundreds of dollars
  • Professionals in need of safely powering high-intensity work or lighting equipment

In the following paragraphs, we shall explore the power characteristics, available outlets, portability, and any additional features of the device, along with its emission compliance information.

Power & Run Time

The Generac RS8000E's core is the 420 cc OHV 4-stroke engine, which runs on gasoline. With an output of 120/240V, it provides a running wattage of 8000W and a peak wattage of 10000W.

Its starting mechanisms include a simple traditional pull-start mechanism and a convenient and easy-to-use electric starter (battery included). It features Generac's PowerDial™, an easy-to-use dial with three operation settings.

With a fuel capacity of 7.5 gallons, the RS8000E may run for around 10.5 hours at 50% load with a full tank (fuel consumption around 0.71 GPH).

Outlets

The control panel features the upcoming 5 AC outlets:

Two Duplexes 120V 20A (5-20R) GFCI
120/240V 30A (L14-30R) receptacle

Since the RS8000E 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

With its dimensions of L30 x W27.1 x H25.7 in, the conventional, open frame design of the Generac RS8000E offers stability and allows the generator to be raised above ground level. The device has been designed for tough environments and demanding outdoor use.

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 213.8 lbs. However, this lack of maneuverability is compensated by its wheel kit (⌀9.5") and its folding handle, with which you can conveniently shift it, once it's on the ground.

Features

Panel of the Generac RS8000E

The RS8000E's control panel

A digital data center, one of the features of the RS8000E's control panel, gives you information on the lifetime run hours, and thus, is helpful for the monitoring of its activity and status.

The generator allows for a quick, easy and convenient assessment of its gas level, as it is equipped with a built-in fuel gauge.

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.

While the standard documentation and an owner's manual (opens in a new tab), helpful for starting the device promptly, come with the Generac RS8000E, the following accessories are also included: battery charger, oil and extension cord.

Emissions

The Generac RS8000E is EPA approved, but NOT CARB-compliant. Thus, it cannot be purchased or sold in California.

However, it features a spark arrestor and therefore, can be used in forested areas.

Product Video

The Generac RS8000E versus other generators

The following charts are provided to give you an idea of how some of the key specs of the Generac RS8000E compare to generators of similar power (between 7500 and 8500 W).

  • As its weight is 213.8 pounds, the Generac RS8000E falls in the expected weight range of the devices in the 7500-8500 rated wattage category. If weight is your top priority, one of the champions in this power category is the Dewalt DXGNR8000, weighing just 183 pounds.
  • Offering around 10.5 hours of running time on a full tank at 50% load, the RS8000E is within the average autonomy range of similarly powerful generators. Concerning the run times, one of the several devices with a comparable output, offering the highest autonomy, is the Champion 100416, which is able to run for around 12.5 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. Standing at an estimated 0.71 GPH (gallon per hour) at a 50% load, this generator is somewhat average in this area compared to other devices, within the aforementioned wattage range. If not satisfied with the afore-mentioned fuel consumption, you may wish to check out the Pulsar PG10000B16. With a fuel consumption of as little as 0.55 GPH, it is one of the most efficient generators currently on the market.
According to our stats, the following comparison is pretty popular: Generac RS8000E vs Generac GP8000E.

Price comparison

As you can see from this interactive chart, when compared to other 7500-8500W generators, the Generac RS8000E 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.
