Description

Zoom on the Powerhorse s12500t

In summary, the Powerhorse s12500t is a powerful portable generator especially useful for:

  • Prudent homeowners who want a full backup power source in case of a power outage
  • Homeowners who want to be sure of their ability to power their fridges, cooking tools, heating and lighting equipment during power failures
  • Professionals who want to be able to deliver results, even during a power failure

In the forthcoming sections, you'll delve into its power characteristics, the various outlets it offers, its overall portability, and the additional features it boasts.

Power & Run Time

The Powerhorse s12500t in use

The Powerhorse s12500t

The Powerhorse s12500t delivers 120/240V and is equipped with a tri-fuel technology, enabling it to operate on gasoline, propane, or natural gas. When powered by gasoline, it achieves a running wattage of 9,500W and a peak wattage of 12,500W. Switching to propane provides 8,550 rated watts and 11,250 peak watts, while natural gas operation delivers 7,125W of rated wattage and 9,375W of starting wattage.

Enjoying a noise rating of 97 dBA (which is pretty noisy), this generator offers the versatility of starting with either a classic hand-operated recoil starting mechanism or a simple and elegant electric starter (battery not included). Additionally, the s12500t features remote starting, offering users increased convenience (key fob included).

Regarding its running time, the s12500t, with a 6.6 gallons fuel tank, can operate for around 9 hours at 50% load with a full gasoline tank (with fuel consumption estimated at around 0.73 gallons per hour). It also offers around 4.2 hours (on a 20 lbs tank - propane consumption around 1.12 GPH) of operation when using propane.

The powering of sensitive electronic devices with the s12500t is not recommended due to its high THD (<23%).

Outlets

The control panel features 6 AC outlets as follows:

Two Duplexes 120V 20A (5-20R) GFCI
120/240V 30A (L14-30R) receptacle
120/240V 50A (14-50R) receptacle

Moreover, it presents 2 DC outlets: there's two 5V USB ports (USB-A) enabling convenient charging of devices like mobile phones and tablets.

Since it features a twist-lock L14-30R receptacle, the s12500t is tailored to be transfer switch ready, making it easy to connect it to your breaker box for home power support during outages.

Portability

At L29.3 x W26.7 x H26.4 in, the Powerhorse s12500t boasts a traditional open frame structure, ensuring stability and allowing for convenient maintenance access to components, promoting air circulation. The design is ideal for rough environments and demanding outdoor use.

Even though this device may be technically portable (as in movable), manipulation and transportation without special equipment can be a challenge, as it weighs 235 pounds. 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.

Features

The s12500t's control panel

Integrated into the control center of the s12500t are a convenient meter, showing voltage, frequency, and lifetime hours metrics, facilitating the monitoring of its status and activity.

In addition to this info, a light indicator on the device will notify you if the oil level is too low.

The inclusion of a built-in fuel gauge in the generator streamlines gas level checks for quick and convenient assessments.

In terms of security, the generator features an automatic low oil shut-off and an overload protection (circuit breaker), ensuring peace of mind during its use.

It also includes a carbon monoxide sensor. This sensor is designed to monitor the level of carbon monoxide present during the generator's operation. If the generator is positioned incorrectly and carbon monoxide levels rise to an unsafe level, the generator will automatically shut down.

Besides the classic documentation and an owner's manual (opens in a new tab) to get you promptly started, the Powerhorse s12500t also comes with some accessories: natural gas hose with NPT adapter, tool kit, key fob, propane hose and funnel are included.

The Powerhorse s12500t versus other generators

The following charts are provided to give you an idea of how some of the key specs of the Powerhorse s12500t compare to multi-fuel generators of similar power (between 9000 and 10000 W).

  • With a weight of 235 lbs, the Powerhorse s12500t sits in the heavier end of the spectrum among multi-fuel generators rated from 9000 to 10000 watts. If weight matters to you, one of the champions in this power range is the Westinghouse iGen12000DFc with only 189 pounds.
  • If compared to generators capable of producing a similar running wattage, this generator with a lowest emitted noise of 97 dBA can be considered somewhat noisy. If noise emissions are important to you, one of the least noisy generators of this power range is the DuroMax XP11000iHT with only 61 dBA.
  • Concerning its runtime, the s12500t provides around 9 hours at a 50% load, indicating that it falls on the lower side compared to other generators of its type and power range. Concerning the run times, one of the several devices with a comparable output, offering the highest autonomy, is the A-iPower GXS12000iRD, which is able to run for around 13 hours.
  • Autonomy holds its importance, however, it is largely dependent on the generator’s fuel capacity and so, it is nonsensible to discuss it without mentioning fuel efficiency as well. Among devices of similar power, this generator has one of the better fuel efficiency, with consumption rates of around 0.73 GPH (gallon per hour) at 50% load. If you wish to further improve in the area of fuel efficiency, the A-iPower GXS12000iRD, which boasts with a gas consumption of only 0.65 GPH, may be the right generator for you.

Price comparison

As you can see from these interactive charts, when compared to other 9000-10000W multi-fuel generators, the Powerhorse s12500t is on the average side of the price range.

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