Zoom on the Powerhorse 13000ES
In a nutshell, the Powerhorse 13000ES is a powerful portable generator mostly geared towards professionals who want to be able to deliver results, even during a power failure.
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 Powerhorse 13000ES houses a 622 cc OHV 4-stroke engine, which provides 120/240V, consumes gasoline and delivers a running wattage of 10,000W along with a peak wattage of 13,000W.
The generator is rated for a noise of 77 dBA (less noisy than a vacuum cleaner). Its starting mechanisms include a conventional pull-start mechanism and a simple and elegant electric starter (battery not included).
With a fuel capacity of 12.6 gallons, the 13000ES may run for around 15 hours at 50% load with a full tank (fuel consumption around 0.84 GPH).
The 13000ES generates a clean sine wave: providing <5% Total Harmonic Distortion (THD), delicate electronics can be plugged in its AC outlets safely.
The control panel includes the following 7 AC outlets:
Additionally, it features 1 DC outlet: there's a 12V 8A (cigarette lighter style) receptacle allowing you to easily charge your batteries.
Even if this Powerhorse generator isn't quite RV Ready, it still allows for an easy RV connection via an L5-30P to TT-30R adaptor, thanks to its L5-30R receptacle. Besides, as the 13000ES 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.
With its dimensions of L33.5 x W24.4 x H25.6 in, the conventional, open frame design of the Powerhorse 13000ES offers stability and allows the generator to be raised above ground level. The generator is designed for ideal use outdoors and in rough environments.
Although this generator is technically considered 'portable' (in the sense that it can be moved), its 324 lbs make it incredibly difficult to manually lift and transport. However, its challenging mobility is solved by its wheel kit and its folding handle, which will ease its displacement, once it is on the floor.
A digital data center, one of the features of the 13000ES's control panel, gives you information on the lifetime run hours and voltage, and thus, is helpful for the monitoring of its activity and status.
A built-in fuel gauge allows for a quick, easy and convenient check of the fuel level of the generator.
As for its security measures, the device features an automatic low oil shut-off and an overload protection (circuit breaker), letting you use it with a peace of mind.
Besides the usual set of documentation and owner's manual (opens in a new tab) to get you promptly started, Powerhorse also included a tool kit in the 13000ES's packaging.
The Powerhorse 13000ES is EPA approved, but NOT CARB-compliant. Thus, it cannot be purchased or sold in California.
However, it features a spark arrestor and therefore, can be used in forested areas.
The Powerhorse 13000ES versus other generators
The following charts are provided to give you an idea of how some of the key specs of the Powerhorse 13000ES compare to generators of similar power (between 9500 and 10500 W).
- Considering its dry weight of 324 pounds, the Powerhorse 13000ES is one of the heavier generators producing between 9500 and 10500 running watts. In terms of weight, one of the champions in their power range is the Westinghouse WGen9500TFc, standing at just 203.4 lbs.
- Among the generators of a comparable running wattage, this generator with a lowest noise of 77 dBA can be judged as noisy. If noise emissions are important to you, one of the least noisy generators of this power range is the A-iPower SUA13000EFI with only 69 dBA.
- Thanks to an impressive running time of around 15 hours at 50% load, the 13000ES benefits from one of the highest run times among generators of a similar output.
- Run times are important, yet thanks to their dependence on the fuel capacity, they should be judged along with the fuel consumption of the device. This generator can be considered as fuel efficient, due to its low estimated fuel consumption of only 0.84 GPH (gallon per hour) at 50% load, within the aforementioned wattage range. If fuel consumption is your top priority, we suggest to check out the Pulsar G12KBN, which has a fuel consumption of only 0.67 GPH and thus, is one of the most efficient devices in our database.
As you can see from this interactive chart, when compared to other 9500-10500W generators, the Powerhorse 13000ES is on the expensive side of the price range.
While certainly not the cheapest of its kind, purchasing it would most likely also mean enjoying the reliability of a high-end product.
The bottom line
- Electric start
- Clean sine wave
- High run time
- Fuel efficient
- On the expensive side
- Battery not included
- No remote start
- Not CARB-compliant
- On the heavy side (324 lbs)
- On the noisy side (77 dBA)

DO NOT BUY this piece of crap machine. Got a blown engine on mine, called Northern Tool/Powerhorse and was told engine parts are not available, only a complete engine for $1100. If something happens to your engine which is highly likely, you’re out off luck for internal parts.
Powerhorse 13000ES is definitely a beast. The electric start is very convenient and easy to use. The power this thing has is amazing, we are in a prone hurricane area and have power outages on regular basis and this beast can almost supply the entire house. We run the AC, our well, microwave all at the same time and never hear this thing struggling. Just have to get the fuel shut off valve fixed, plastic valve won’t shut the fuel off. Want to replace it with a metal valve to see if that fixes the problem.
