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 who want to ensure that a power failure will not prevent them from working
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's engine, 420 cc OHV 4-stroke, fueled by gasoline, can deliver 120/240V. It provides a running wattage of 6500W and reaches a peak wattage of 8125W.
This generator features a conventional pull-start mechanism and also a simple and elegant electric starter (battery included).
Thanks to a fuel capacity of 7.9 gallons, the RP6500 E can operate for around 12 hours at 50% load with a full tank (fuel consumption around 0.66 GPH).
The control panel features the following 6 AC outlets:
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.
The dimensions of the Cat RP6500 E, which are L32.9 x W27.4 x H24.7 in, and its typical, open frame design provides stability and enables the generator to be raised above ground level. The design is ideal for rough environments and demanding outdoor use.
Since the generator weighs 202 lbs, it will be incredibly difficult to manually lift it and transport it, even though it is technically considered to 'be portable' (in the sense that it is movable). 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.
The RP6500 E's control center features a convenient meter showing you voltage, frequency and lifetime hours to aid you with the monitoring of its status and activity. To offer you even more control and easy operation during night time, the panel is LED-lit.
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.
Apart from the typical documentation and an owner's manual (opens in a new tab), which lets you start it right away, the Cat RP6500 E also is packed along with the following accessories: tool kit, oil and funnel.
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 and therefore, can be used in forested areas.
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).
- Since the generator weighs in at a dry weight of 202 lbs, the Cat RP6500 E belongs in the expected weight range for devices which can produce between 6000 and 7000 rated watts. In terms of weight, one of the champions in their power range is the Sportsman GEN85KIDF, standing at just 133 lbs.
- Since the RP6500 E boasts with a run time of around 12 hours at 50% load, it can be safely judged as a device of a higher run time than most generators of a comparable output. 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.
- 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 average fuel consumption among comparably powerful devices, as it reaches 0.66 GPH (gallon per hour) at a 50% load. If not satisfied with the afore-mentioned fuel consumption, you may wish to check out the Lifan ESI 7000iER-EFI. With a fuel consumption of as little as 0.38 GPH, it is one of the most efficient generators currently on the market.
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.
The bottom line
- In the expected price range
- Several accessories included
- GFCI Outlets
- Electric start
- High run time
- Decent weight (202 lbs)

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.
