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.

It can run for about 9 hours if propane is used (on a 20 lbs tank – propane consumption around 0.52 GPH). Since the T04073 has a THD of about 14%, it shouldn’t be used to power electronics that are sensitive to noise.

Outlets

The following 4 AC outlets are on the control panel: Duplex 120V 20A (5-20R) GFCI; 120V 30A (L5-30R) receptacle; 120/240V 30A (L14-30R) receptacle. Even though this Firman generator isn’t quite RV Ready, an L5-30P to TT-30R adapter makes it easy to connect it to an RV (included). The T04073 also has a twist-lock L14-30R receptacle, which makes it ready for a transfer switch. You can easily connect it to your breaker box to power your home when the power goes out.

Features

The T04073’s control panel has a handy meter that shows voltage, frequency, and lifetime hours. This makes it easy to keep track of its status and activity. In addition to this information, the light indicator will let you know when the generator is ready to use. The generator has a built-in fuel gauge that makes it quick, easy, and convenient to check how much gas is in it. When it comes to safety, this product has a circuit breaker for overheating and an automatic shut-off for low oil, so you can use it without any worries. The T04073 also has Firman’s CO Alert carbon monoxide shutdown, which turns the engine off automatically when harmful levels of carbon monoxide build up around the generator or when a CO Alert fault happens. It’s a nice extra safety measure, but don’t forget to take your generator outside at all times. Along with the basic paperwork and an owner’s manual that will help you start the generator right away, the Firman T04073 comes with a tool kit, a cover, an RV adapter, oil, a funnel, and a propane hose.

Mobility

With dimensions of L29.8 x W27.5 x H26.1 in, the Firman T04073 is a traditional, open-frame generator that is stable and can be raised above ground level. The design shown is great for the outdoors and other rough places. Even though this device is technically portable (meaning it can be moved), it can be hard to move and use without special tools because it weighs 123.4 pounds. Still, once it is on the ground, its 8-inch-diameter wheel kit and folding handle can easily solve the problem of low mobility and make it easy to move the device.

Description

A 357 cc Yamaha MZ360 OHV 4-stroke engine powers the Yamaha EF4500iSE. It runs on gasoline and has a running wattage of 4,000W and a peak wattage of 4,500W. It gives off 120V. This inverter generator has a noise level of 58 dBA, which is quieter than rain. An electric starter makes it easy to get it going (battery included). Yamaha’s Smart ThrottleTM is built into this generator. This load-sensing feature automatically changes the speed of the engine to match how much it is being used. This saves fuel and reduces noise. The EF4500iSE can run for up to 15.2 hours on a full tank of fuel, which is 4.5 gallons (fuel consumption is approximately 0.3 GPH). The EF4500iSE makes a clean sine wave with a Total Harmonic Distortion of less than 3%, so it’s safe to plug sensitive electronics into AC outlets (THD).

Outlets

The control panel has 3 AC outlets: a duplex 120V 20A (5-20R) receptacle, a 120V 30A (L5-30R) receptacle, and a 120V 20A (5-20R) receptacle. This Yamaha generator isn’t quite RV Ready, but it has an L5-30R receptacle that makes it easy to connect to an RV with an L5-30P to TT-30R adapter.

Features

The EF4500iSE’s control panel has a digital data center that tells you how long it has been running and how much power it is putting out. This helps you keep track of its status and activity. In addition to this information, the generator has a number of lights that tell you when it is ready, when it is overloaded, and when the oil level is too low. The inverter generator has a built-in fuel gauge that makes it quick, easy, and convenient to find out how much gas is in it. As for safety features, the device has a circuit breaker for overheating and an Oil Watch system that turns it off automatically when the oil level gets too low, so you can use it without worrying. The Oil Watch warning system from Yamaha gives you more peace of mind. This feature makes the car last longer because it keeps the engine from getting damaged and needing expensive repairs. When the oil gets low, the generator turns off by itself and won’t start again until more oil is added. It also has a sensor for carbon monoxide. This sensor is meant to measure the amount of carbon monoxide in the air while the generator is running. If the generator isn’t set up right and carbon monoxide levels get too high, the generator will turn off by itself. It’s a nice extra safety measure, but don’t forget to take your generator outside at all times. Aside from the features we’ve already talked about, the Yamaha EF4500iSE also comes with the basic paperwork and an owner’s manual, so you can start using it right away. You can buy a storage cover from the company separately.

Mobility

Since the Yamaha EF4500iSE is an inverter generator, its enclosed design (L30.7 x W24.3 x H27.8 in) looks better than a traditional open frame product. The generator has a modern look and is easy to use when generating power for fun. The generator is technically “portable” in the sense that it can be moved, but at 194 pounds, it may be hard to move it by hand. Still, the generator is easy to move once it’s on the ground because it has 4 wheels and a double handle, which makes up for the fact that it’s not very maneuverable.

The generator has a built-in fuel gauge that makes it easy to see at a glance how much gas is in the tank. 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 WEN DF472 comes with a standard set of instructions and an owner’s manual to get you started right away. It also comes with a propane hose and oil.

Mobility

The WEN DF472 is 23.1 inches long, 17.5 inches wide, and 18.5 inches high. Together with its traditional, open-frame design, they support the generator and allow it to be raised above the ground. The design works well in rough places and for hard outdoor use. The generator weighs 103.2 pounds, so it may be hard to move or transport it by hand, even though it is technically considered “portable” (movable).

  • 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

With its dual-fuel technology, the WEN DF472X can run on either 120V or 240V, giving it power and flexibility. When powered by gasoline, it has a running wattage of 3,800W and a maximum wattage of 4,750W. When run on propane, it has a rated power of 3500 watts and a peak power of 4350 watts. This generator is turned on with a simple, old-fashioned pull-start. With a fuel capacity of 4 gallons, the DF472X can run for about 11 hours at 0.5 load on gasoline (using about 0.36 GPH of fuel), or about 7 hours on a 20 lb tank (using about 0.67 GPH of propane).

Outlets

The control panel has 3 AC outlets: a duplex 120V 20A (5-20R) GFCI outlet and a 120/240V 30A (L14-30R) outlet. It also has 1 DC outlet: a 12V 8A plug that looks like a cigarette lighter so you can easily charge your batteries. The DF472X 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 generator has a built-in fuel gauge that makes it easy to see at a glance how much gas is in the tank. When it comes to safety, this product has a circuit breaker for overheating and an automatic shut-off for low oil, so you can use it without any worries. The unit also works well because WEN’s CO Watchdog can detect carbon monoxide. This system keeps track of how much CO gas is being made while the generator is running. If there is too much CO gas, the CO Watchdog system will turn off the generator automatically. It’s a nice extra safety measure, but don’t forget to always take your generator outside. The WEN DF472X package comes with basic paperwork and an owner’s manual that will help you start the generator right away. It also comes with a propane hose, oil, and a tool kit.

Mobility

The WEN DF472X has a typical open frame that is L23.1 x W17.5 x H18.5 in, This gives it support and stability and gives you the option to raise it above ground level. This type of design is great for tough environments and heavy outdoor use. Even though this device is technically portable (meaning it can be moved), it can be hard to move and use it without special tools because it weighs 102.5 pounds.
