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
Power & Run Time
The Cat RP6500 E houses a 420 cc OHV 4-stroke engine, which provides 120/240V, consumes gasoline and delivers a running wattage of 6,500W along with a peak wattage of 8,125W.
This generator features a simple traditional pull-start mechanism and also 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).
The control panel features the upcoming 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 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. 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 202 lbs make it incredibly difficult to manually lift and transport. Still, once it is on the ground, its wheel kit and its folding handle can easily solve the issue of low mobility and allow for easy relocation of the device.
The RP6500 E's status and activity may be monitored conveniently via the control panel, as it features a convenient meter, which displays voltage, frequency and lifetime hours. To offer you even more control and easy operation during nighttime, the panel is LED-lit.
The generator includes a built-in fuel gauge, a quick, easy and convenient method of checking the device’s gas level.
As far as security is concerned, the generator can be used with a peace of mind, as it features an overload protection (circuit breaker) and an automatic low oil shut-off.
Besides the classic documentation and an owner's manual (opens in a new tab) to get you promptly started, the Cat RP6500 E also comes with some accessories: oil, tool kit and funnel are included. An official storage cover is also available, as a separate purchase.
The Cat RP6500 E is EPA-approved and CARB-compliant. Therefore, its sale and purchase are permitted in all 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).
- 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. If weight is your top priority, one of the champions in this power category is the Sportsman GEN85KIDF, weighing just 133 pounds.
- With a run time of around 12 hours at 50% load, the RP6500 E has one of the higher run times, compared to its similarly powerful peers. Concerning the run times, one of the several devices with a comparable output, offering the highest autonomy, is the Generac XC6500E, which is able to run for 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. Compared to its peers, this generator is not exactly fuel efficient, compared to similarly powerful devices, with an estimated fuel consumption of 0.66 GPH at a 50% load. 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.
