Description

The DuroStar DS10000EH is powerful and flexible, thanks to its dual-fuel technology that lets it run on both 120V and 240V. When it is running on gasoline, it has a running wattage of 8,000W and a peak wattage of 10,000W. When run on propane, it has a rated power of 7600 watts and a peak power of 9500 watts. The generator can make up to 72 dBA of noise (slightly noisier than running a dishwasher It has both a traditional pull-start mechanism and an electric starter that is convenient and easy to use (battery included). With a full tank of gasoline, the DS10000EH, which has a fuel capacity of 8.2 gallons, can run for about 10 hours at 0.5 load (fuel consumption is approximately 0.82 GPH). It can run for about 4.5 hours if you use propane (on a 20 lbs tank – propane consumption around 1.04 GPH). The DS10000EH can’t be used to power sensitive electronics because its THD is quite high (12%).

Outlets

The control panel has 5 AC outlets: a duplex 120V 20A (5-20R) GFCI outlet, a 120V 30A (L5-30R) outlet, a 120/240V 30A (L14-30R) outlet, and a 120/240V 50A (14-50R) outlet. It also has 1 DC outlet with a 12V 8A output that makes it easy to charge your batteries. With an L5-30P to TT-30R adapter, this DuroStar generator’s L5-30R receptacle makes it easy to connect it to an RV. But it’s still not ready for an RV. Also, the DS10000EH is ready for a transfer switch because it has a twist-lock L14-30R receptacle. It is easy to connect to a breaker box and can power your home if the power goes out.

Features

The DS10000EH’s control panel has a voltmeter that makes it easy to check the power output at any time. This is helpful for keeping track of its status and activity. Along with this information, a light lets you know right away if the oil level is too low. The generator has a built-in fuel gauge that makes it quick, easy, and convenient to check how much gas is in it. From a safety point of view, the product has a circuit breaker for overload protection and an automatic shut-off for low oil, so you can use it without worry. The DuroStar DS10000EH comes with a tool kit, battery charging cables, a propane hose, and a funnel. It also comes with basic instructions and an owner’s manual to help you get started right away. You can also buy a storage cover that is made by the company.

Mobility

The DuroStar DS10000EH is 29 inches long, 30 inches wide, and 26 inches high. It has a typical open frame design that makes it stable and allows it to be raised above ground level. The design works well in rough places and for hard outdoor use. The generator is technically “portable” in the sense that you can move it, but at 220 pounds, it may be hard to move it by hand. 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.

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.

Description

The DuroStar DS5000DX is powerful and flexible, thanks to its dual-fuel technology that lets it run on both 120V and 240V. When it is running on gasoline, it has a running wattage of 4,000W and a peak wattage of 5,000W. When run on propane, it has a rated power of 3800 watts and a peak power of 4750 watts. The generator is meant to make 69 dBA of noise (less noisy than an office). It has a simple pull-start mechanism and a simple and elegant electric starter to get it going (battery included). With a 4 gallon fuel tank, the DS5000DX can run for about 8.9 hours at 0.5 load when using gasoline (fuel consumption is approximately 0.45 GPH). If you use propane instead, it can run for about 7.6 hours on a 20-pound tank (propane uses about 0.62 GPH). Since the DS5000DX has a THD of about 12%, it should not be used to power sensitive electronics.

Outlets

On the control panel, there are 3 AC outlets for: Duplex 120V 20A (5-20R) GFCI; 120/240V 30A (L14-30R) receptacle. The DS5000DX is ready for a transfer switch because it has a twist-lock L14-30R receptacle. You can easily connect it to your breaker box to power your home when the power goes out.

Features

The control center of the DS5000DX has a handy meter that shows voltage, frequency, and lifetime hours. This helps you keep track of its status and activity. In addition to this information, a light lets you know right away if the oil level is too low. The generator has a built-in fuel gauge that makes it quick, easy, and convenient to check how much gas is in the machine. For safety, the generator has an overload protection (circuit breaker) and an automatic low oil shut-off, so you can use it without worrying. The DuroStar CO Alert carbon monoxide shutdown also works well with the DS5000DX. If CO levels get too high too quickly, the generator will shut down automatically, a red light will come on, and the engine won’t start again for 5 minutes. It’s a nice extra safety measure, but don’t forget to take your generator outside at all times. The DuroStar DS5000DX comes with basic instructions and an owner’s manual to help you start the generator quickly. It also comes with a propane hose, funnel, and tool kit, among other things.

Mobility

The standard, open frame design of the DuroStar DS5000DX, which is 25 inches long, 23 inches wide, and 22 inches high, gives the generator stability and lets it be raised above ground level. This type of design is great for tough environments and heavy outdoor use. The generator weighs 135 pounds, so it may be hard to move or transport it by hand, even though it is technically considered “portable” (movable). But its wheels and folding handle make it easier to move once it’s on the floor.

For safety, the generator has an overload protection (circuit breaker) and an automatic low oil shut-off, so you can use it without worrying. The DuroStar CO Alert carbon monoxide shutdown also works well with the DS5000X. If CO levels get too high too quickly, the generator will shut down automatically, a red light will come on, and the engine won’t start again for 5 minutes. It’s a nice extra safety measure, but don’t forget to take your generator outside at all times. The DuroStar DS5000X comes with more than just the usual paperwork and an owner’s manual to get you up and running quickly. There is a tool kit and a funnel.

Mobility

The DuroStar DS5000X is 25 inches long, 23 inches wide, and 22 inches high. It has a typical open frame design that makes it stable and allows it to be raised above ground level. The generator is built to work well outside and in rough places. The generator is technically “portable” in the sense that you can move it, but at 130 pounds, it may be hard to move it by hand. But its wheel kit and folding handle make it easy to move once it’s on the ground, which makes up for its lack of maneuverability.

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.

Description

The 208 cc (7 hp) gasoline-powered DuroStar OHV 4-stroke engine in the DuroStar DS4400E can put out 120/240V. It has a running power of 3,500W and a maximum power of 4,400W. This generator has a noise level of 69 dBA, which is quieter than background music. It can be started with a pull-start, but it also has a simple and elegant electric starter (battery included). With a full tank, the DS4400E can run for about 11.5 hours at 0.5 load (using about 0.35 GPH of fuel). This is because it has a 4 gallon fuel tank. Since the DS4400E has a THD of about 12%, it is best not to use it to power electronics that are sensitive to noise.

Outlets

There are 3 AC outlets on the control panel: a duplex 120V 20A (5-20R) GFCI outlet and a 120/240V 30A (L14-30R) outlet. It also has 1 DC outlet with a 12V 8A output that makes it easy to charge batteries. The DS4400E is ready for a transfer switch because it has a twist-lock L14-30R receptacle. It can be easily connected to a breaker box and can power your home if the power goes out.

Features

The DS4400E’s control panel has a voltmeter that makes it easy to check the power output at any time. This is helpful for keeping track of its status and activity. In addition to this information, if the oil level is too low, a light on the device will show. The generator has a built-in fuel gauge that makes it quick, easy, and convenient to find out how much gas is in it. In terms of safety, the generator can be used without worry because it has a circuit breaker for overheating and an automatic shut-off when the oil level gets too low. The DuroStar DS4400E comes with the usual paperwork and an owner’s manual , which lets you start it right away. It also comes with a funnel, a tool kit, and battery charging cables. You can also buy a storage cover that is made by the company.

Mobility

The DuroStar DS4400E has a typical open frame that is 25 inches long, 24 inches wide, and 21 inches high. This gives it support and stability and gives you the option of raising it above ground level. The design works well in rough places and for hard outdoor use. The generator is technically “portable” because it can be moved, but at 122 pounds, it may be hard to move it by hand. Still, because of its wheel kit (dia:8 “Once the generator is on the ground, it is easy to move thanks to its wheels and folding handle, which make up for its lack of maneuverability.
