Zoom on the Cat RP6500 E

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

  • 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
  • Professionals in need of safely powering high-intensity work or lighting equipment

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 Cat RP6500 E in use

The Cat RP6500 E

The Cat RP6500 E is powered by a 420 cc OHV 4-stroke engine. It delivers 120/240V, runs on gasoline and offers a running wattage of 6500W as well as a peak wattage of 8125W.

This generator can be started thanks to a conventional pull-start mechanism, but also to a convenient and easy-to-use electric starter (battery included).

With a fuel capacity of 7.9 gallons, the RP6500 E may run for around 12 hours at 50% load with a full tank (fuel consumption around 0.66 GPH).

Outlets

The control panel includes the following 6 AC outlets:

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

This Cat generator isn't quite RV Ready, but it features an L5-30R receptacle, allowing a simple RV connection through an L5-30P to TT-30R adaptor. Besides, since the RP6500 E 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 Cat RP6500 E has a conventional, open frame design, of the following dimensions: L32.9 x W27.4 x H24.7 in, which offers support and allows it to be raised above ground level. The generator is designed for ideal use outdoors and in rough environments.

As the generator's weight is 202 pounds, manually moving it or transporting it may be challenging, despite the fact that it is technically considered 'portable' (movable). However, this lack of maneuverability is compensated by its wheel kit and its folding handle, with which you can conveniently shift it, once it's on the ground.

Features

Panel of the Cat RP6500 E

The RP6500 E's control panel

To help you monitor the RP6500 E's status and activity, its control panel is equipped with a convenient meter, which displays voltage, frequency and lifetime hours. To offer you even more control and easy operation during night time, the panel is LED-lit.

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 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.

Along the basic documentation and an owner's manual (opens in a new tab), useful for starting the generator right away, the Cat RP6500 E's package also includes these accessories: funnel, tool kit and oil.

Emissions

The Cat RP6500 E is EPA-approved and CARB-compliant. Thus, selling and purchasing this generator is allowed in each of the 50 states, including California.

Moreover, it features a spark arrestor, which makes it suitable for use in forested areas.

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).

  • With a dry weight of 202 pounds, the Cat RP6500 E finds itself in the expected weight range for generators able to produce between 6000 and 7000 rated watts. If weight matters to you, one of the champions in this power range is the Sportsman GEN85KIDF with only 133 pounds.
  • As the RP6500 E features an autonomy of around 12 hours at 50% load, it has a higher run time than an average generator of its power range. If concerned with autonomy, one of the products of a comparable power output, which offers the highest run time, is the Generac XC6500, boasting with around 14 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 0.66 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 fuel consumption is your top priority, we suggest to check out the Lifan ESI 7000iER-EFI, which has a fuel consumption of only 0.38 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 6000-7000W generators, the Cat RP6500 E is on the average side of the price range.

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

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.

    The pull start assembly broke after the 5th pull. Now I have to wrap the rope around the thingamajig to pull start it and it’s not really electric start.
    Very disappointed for $1100 investment.

    + PROS:
    • Runs good
    - CONS:
    • The windings in the pull start broke after the 5th time I cranked. Now I have to physically wrap the pull rope around the think to pull start it
