Description
Zoom on the Powerhorse s12500t
To sum up, the Powerhorse s12500t is a powerful portable generator tailored for:
- Homeowners who wish to power almost all appliances in their house under any circumstances
- Homeowners who want to be sure of their ability to power their fridges, cooking tools, heating and lighting equipment during power failures
- Professionals in need of safely powering high-intensity work or lighting equipment
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 delivers 120/240V and boasts with a tri-fuel technology enabling it to utilize gasoline, propane, or natural gas. When powered by gasoline, it achieves a running wattage of 9,500W and a peak wattage of 12,500W. Upon using propane, it gains 8,550 rated watts and 11,250 peak watts. Its operation with natural gas provides 7,125W of rated wattage and 9,375W of starting wattage.
The generator, rated for a noise of 97 dBA (which is pretty noisy), provides flexibility in starting, offering both a manual recoil starter system and a simple and elegant electric starter (battery not included). For additional convenience, the s12500t may also be remotely started (key fob included).
With a fuel capacity of 6.6 gallons, the s12500t can operate for around 9 hours at 50% load using gasoline (fuel consumption around 0.73 GPH), or for around 4.2 hours (on a 20 lbs tank - propane consumption around 1.12 GPH) using propane.
The quite high THD (<23%) of the s12500t makes it unsuitable for powering sensitive electronic devices.
Outlets
The control panel features the following 6 AC outlets:
In addition, it provides 2 DC outlets: there's two 5V USB ports (USB-A) enabling convenient charging of devices like mobile phones and tablets.
Because the s12500t is equipped with a twist-lock L14-30R receptacle, it is transfer switch ready: it can power your home during a power outage, as it can be easily connected to your breaker box to power your household.
Portability
Measuring L29.3 x W26.7 x H26.4 in, the Powerhorse s12500t showcases a classic open frame layout, guaranteeing stability and simple maintenance access to components, while facilitating air circulation. The design is ideal for rough environments and demanding outdoor use.
With a weight of 235 lbs, the generator is still labeled as 'portable,' denoting its ability to be moved, although its heaviness might restrict easy portability. 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
For convenient monitoring of its status and activity, the control panel of the s12500t includes a convenient meter, which displays voltage, frequency and lifetime hours.
In addition to this info, a light indicator on the device will notify you if its oil levels are insufficient.
The generator includes a built-in fuel gauge, a quick, easy and convenient method of checking the device’s gas level.
From a security point of view, the generator is equipped with an automatic low oil shut-off and an overload protection (circuit breaker), giving you a peace of mind during 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.
With the basic documentation and an owner's manual (opens in a new tab), letting you start the generator quickly, the Powerhorse s12500t also comes with several accessories, including: natural gas hose with NPT adapter, funnel, key fob, propane hose and tool kit.
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).
- Weighing in at 235 lbs, the Powerhorse s12500t is one of the heaviest multi-fuel generators available in the 9000-10000 rated wattage segment. If weight is an important consideration for you, the Westinghouse iGen11000DFc stands out as one of the top contenders in this power category, with a dry weight of 187.4 pounds.
- Among the generators of a comparable running wattage, this generator with a lowest noise of 97 dBA can be judged as noisy. If you’d prefer a less noisy device, one of the most quiet devices, which share the same power range with this one, is the DuroMax XP11000iH, whose lowest noise levels reach just 61 dBA.
- At a 50% load, the s12500t offers around 9 hours of runtime on a full tank, placing it within the average autonomy range among multi-fuel generators of similar power level. Concerning the run times, one of the several devices with a comparable output, offering the highest autonomy, is the Predator 13000, which is able to run for around 12.1 hours.
- While run time is vital, it hinges on the fuel capacity. To grasp the full picture, we must also factor in fuel efficiency. This generator can be considered as fuel-efficient, due to its low estimated fuel consumption of only 0.73 GPH (gallon per hour) at 50% load, within the aforementioned wattage range. If you wish to get a unit of similar power, but with one of the best fuel efficiency, you could consider the Westinghouse iGen11000DFc, which has an impressively low fuel consumption of 0.66 GPH.
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 cheap side of the price range.
It can therefore be a really good buy if you're looking to acquire a budget generator.
