Description

A GREAT SOLUTION FOR LIGHT COMMERCIAL OR RESIDENTIAL NEEDS. This electric start generator, is a good option for keeping your business or home up and running. Cat portable generators are equipped with electric starters and lithium ion batteries that automatically recharge whenever the generator is running. Our power will be ready when you are. A single-side, LED-lit panel contains all of the power outlets and controls in one intuitively-designed location, including the start/stop switch, choke, and fuel shutoff switch.

Zoom on the Cat RP6500 E

In a nutshell, the Cat RP6500 E is a portable generator mostly geared towards:

  • Food truck owners who want to ensure that their business is fully self-contained and does not rely on potentially unreliable external power
  • Homeowners in need of an emergency backup power for their essentials
  • Professionals who want to ensure that a power failure will not prevent them from working

In the upcoming sections, you'll discover its power characteristics, the array of outlets it presents, its overall portability, and the additional features it possesses.

Power & Run Time

The Cat RP6500 E in use

The Cat RP6500 E

With a 420 cc OHV 4-stroke engine, the Cat RP6500 E operates on gasoline, providing 120/240V, with a running wattage of 6,500W and a starting wattage of 8,125W.

Its starting mechanisms include a classic hand-operated recoil starting mechanism and a convenient and efficient electric starter (battery included).

The RP6500 E's fuel tank, with a capacity of 7.9 gallons, supports uninterrupted operation for around 12 hours at 50% load when fully fueled (fuel consumption at an estimated 0.66 gallons per hour).

Outlets

The control panel features the upcoming 6 AC outlets:

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

Despite not meeting the 'RV Ready' criteria, this Cat generator grants the advantage of simple RV compatibility via its L5-30R receptacle, enabling you to conveniently power your RV by using an L5-30P to TT-30R adaptor. Besides, as the RP6500 E holds a twist-lock L14-30R receptacle, it is transfer switch ready: you'll easily be able to connect it to your breaker box to power your home during a power outage.

Portability

At L32.9 x W27.4 x H24.7 in, the traditional open frame structure of the Cat RP6500 E ensures stability while facilitating convenient maintenance access to components and promoting air cooling. The design is ideal for rough environments and demanding outdoor use.

Even at 202 lbs, the generator is categorized as 'portable,' suggesting its movability, although its weight impede its portability. Despite the restricted maneuverability, its wheel kit and its folding handle provides a solution, allowing for convenient shifting once the generator is positioned on the ground.

Features

Panel of the Cat RP6500 E

The RP6500 E's control panel

The control panel of the RP6500 E is equipped with a convenient meter, offering voltage, frequency, and lifetime hours readings, aiding in monitoring its status and activity. To offer you even more control and easy operation during nighttime, the panel is LED-lit.

With its built-in fuel gauge, the generator provides quick and convenient gas level checks.

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.

With the basic documentation and an owner's manual (opens in a new tab), letting you start the generator quickly, the Cat RP6500 E also comes with several accessories, including: oil, funnel and tool kit. An official storage cover is also available, as a separate purchase.

Product Video

The Cat RP6500 E versus other generators

The following charts are provided to give you an idea of how some of the key specs of the Cat RP6500 E compare to generators of similar power (between 6000 and 7000 W).

  • At a weight of 202 pounds, the Cat RP6500 E places in the expected weight range of the generators in the 6000-7000 rated wattage range. Regarding dry weight, one of the champions in the same power range is the Pulsar PGDA70BiSCO, with a dry weight of only 118 lbs.
  • Compared to devices of similar power, the RP6500 E stands out with one of the higher run times, lasting around 12 hours at 50% load. If prolonged run time is essential to your needs, you could consider the Pulsar PG7500, which offers one of the highest autonomy among devices with similar power output, lasting around 13 hours.
  • Run time is crucial, but it heavily relies on the fuel tank's capacity. Thus, considering fuel efficiency alongside is essential. In fact, this generator is not one of the most fuel-efficient options in the aforementioned wattage range: its estimated gasoline consumption at 50% load is around 0.66 GPH. If not satisfied with the afore-mentioned fuel consumption, you may wish to check out the A-iPower SUA7000L. With a fuel consumption of as little as 0.36 GPH, it is one of the most efficient generators currently on the market.

Can this generator run your home a/c and other small appliances at the same time? (Asked June 09, 2020)

Considering that it is recommended to not exceed an 80% load, this unit can run for 5200W (6500*0.8) worth of appliances at the same time. While this should normally be plenty for what you mentioned, you'd need to know the actual wattage needs of your own a/c and appliances. Feel free to use our wattage calculator to help you assess your power needs, as it allows you to add custom appliances.

is it rain proof (Asked August 28, 2021)

The unit should be properly sheltered. We recommend reading our article on generator operation in bad weather.

    I used my cat 6500 in 2 hurricanes, both times our power was out for 10 days. It worked great. Especially at night we would run a 2 ton Ac at 20 amps for 10 hours. No problem. I’m very happy with my CAT.

    • Always started first pull.it ran for 10 days straight except fuel and maintenance 2 different times with no problems.
    - CONS:
    • None to report. It preformed better than I expected.
