Description

ECONOMICAL TEMPORARY POWER SOLUTION. This compact, affordable model will generate enough power to keep the critical items you need running. (source: Cat (opens in a new tab))

Zoom on the Cat RP3600

In summary, the Cat RP3600 is a portable generator especially useful for:

  • RV travellers who wish to upgrade their experience to another level
  • Occasional participants of outdoor events, competitions, concerts and festivals
  • Homeowners who want to be sure of their ability to power their fridges, cooking tools, heating and lighting equipment during power failures

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 RP3600 in use

The Cat RP3600

The Cat RP3600's core is the 212 cc OHV 4-stroke engine, which runs on gasoline. With an output of 120V, it provides a running wattage of 3600W and a peak wattage of 4500W.

This generator features a conventional pull-start mechanism.

The fuel capacity of 4.5 gallons allows the RP3600 to operate for around 13.5 hours at 50% load with a full tank (fuel consumption around 0.33 GPH).

Outlets

The control panel provides the upcoming 5 AC outlets:

Two Duplexes 120V 20A (5-20R)
120V 30A (TT-30R) receptacle

This Cat generator is RV Ready, thanks to its TT-30R receptacle (TT stands for 'Travel Trailer').

Portability

With its dimensions of L28.4 x W25.2 x H23 in, the conventional, open frame design of the Cat RP3600 offers stability and allows the generator to be raised above ground level. The featured design is ideal for the outdoors and all tough environments.

Even though this device may be technically portable (as in movable), manipulation and transportation without special equipment can be a challenge, as it weighs 125 pounds. Nevertheless, thanks to its wheel kit and its folding handle (a decent solution to its lack of maneuverability), the generator can be easily moved, once placed the ground.

Features

Panel of the Cat RP3600

The RP3600's control panel

To help you monitor the RP3600's status and activity, its control panel is equipped with a convenient meter showing you voltage, frequency and lifetime hours. To offer you even more control and easy operation during night time, 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.

Security-wise, this product benefits from an overload protection (circuit breaker) and an automatic low oil shut-off, which gives you a complete peace of mind when using it.

While the standard documentation and an owner's manual (opens in a new tab), helpful for starting the device promptly, come with the Cat RP3600, the following accessories are also included: funnel, tool kit and oil.

Emissions

The Cat RP3600 is EPA-approved and CARB-compliant. It can therefore be sold and purchased in all 50 states, including California.

Moreover, it features a spark arrestor and thus, may be used in forested areas.

Product Videos

The Cat RP3600 versus other generators

The following charts are provided to give you an idea of how some of the key specs of the Cat RP3600 compare to generators of similar power (between 3500 and 4500 W).

  • Having a dry weight of 125 lbs, the Cat RP3600 belongs in the expected weight range for generators which produce 3500 to 4500 rated watts. In terms of weight, one of the champions in their power range is the WEN GN400i, standing at just 66.1 lbs.
  • Since the RP3600 boasts with a run time of around 13.5 hours at 50% load, it can be safely judged as a device of a higher run time than most generators of a comparable output. Furthermore, considering the run times, one of the generators which have a roughly same power output, with the highest autonomy, is the Honda EB4000X, as it provides around 16 hours.
  • The run time is important, but also hugely depends on the capacity of the fuel tank and doesn't mean much if we don't talk about fuel consumption as well. This generator is one of the more fuel efficient models of the aforementioned output range, as its estimated fuel consumption reaches just 0.33 GPH (gallon per hour) at 50% load. If fuel consumption is your top priority, we suggest to check out the Westinghouse iGen4200, which has a fuel consumption of only 0.17 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 3500-4500W generators, the Cat RP3600 is on the average side of the price range.

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