The Powerhorse 4000 is made with a 212 cc OHV 4-stroke engine that runs on gasoline. It has an output voltage of 120/240V and a running wattage of 3,100W and a peak wattage of 4,000W. This generator has a noise rating of 95 dBA, which is pretty loud, and it starts up with a simple pull-start mechanism. With a fuel capacity of 3.9 gallons, the 4000 can run at 0.5 load for about 10.6 hours on a full tank (fuel consumption is approximately 0.37 GPH). The 4000 makes a clean sine wave. With a Total Harmonic Distortion (THD) of less than 5%, you can safely plug your sensitive electronics into the AC outlets.
The control panel has nine AC outlets: four 120V 20A (5-20R) duplex outlets and one 120V/240V 30A (L14-30R) receptacle.It also has 1 DC outlet: a 12V 8A plug that looks like a cigarette lighter so you can easily charge your batteries.The 4000 is ready for a transfer switch because it has a twist-lock L14-30R receptacle.You can connect it to a breaker box to power your home when the power goes out.
On the 4000’s control panel, there is a voltmeter that makes it easy to check the power output at any time and keep track of its status and activity.In addition to this, the featured light indicator will let you know when the oil level is too low.The generator has a built-in fuel gauge that makes it easy to see at a glance how much gas is in the tank.From a safety point of view, the product has an automatic shut-off for low oil and an overload protection (circuit breaker), so you can use it without worrying.Along with the features we’ve already talked about, the Powerhorse 4000 comes with standard documentation and an owner’s manual to help you get started right away.
The Powerhorse 4000 is made with a typical open frame that is L25.4 x W18.8 x H19.8 in, This gives it support and stability and gives you the option of raising it above the ground.This type of design is great for tough environments and heavy outdoor use.The generator weighs 115 pounds, so it may be hard to move or transport it by hand, even though it is technically considered “portable” (movable).Still, the generator is easy to move once it’s on the ground, thanks to its wheel kit and folding handle, which is a good way to make up for its lack of maneuverability.
The following charts show how some of the most important features of the Powerhorse-4000 compare to other generators with the same power output.

- We compared more than 500 portable generators at 50% load. We found that there is “skewed right” distribution for the difference between 50% load and 25% load and the median comes at 1.43. With this number we converter all the 25% load runtime to 50% load. Same with the propane efficiency, where median is 1.38.
- For some generators where propane runtime was not given, we used NIST 1994 GGE (Gasoline Gallon Equivalent) formula: 5.66 lbs. of propane = 1 gal of gasoline. All propane runtime is for 20 lbs. propane tank (4.7 gallons).
- Unlike many other sites, we actually tried to find out information about each of the above requirements. However, we are human and are therefore capable of the odd oversight or mistake. Please let us know if you spot any missing or erroneous values so that we can fix them.
