Features & Functions of the DuroMax XP4850EH Dual Fuel Hybrid Generator

Have you been looking for a generator that’s both efficient and environmentally friendly? The DuroMax XP4850EH Dual Fuel Hybrid Generator offers the best of both worlds. You can operate it by using one of two fuel sources:

  • Standard gasoline
  • Cleaner-burning liquid propane

In a pinch, you can get by on standard gasoline. However, opting to use cleaner-burning liquid propane will help you decrease your carbon footprint.

Now that we’ve gotten the question of propane vs. gasoline out of the way, you may be wondering what else this generator has to offer. Check out the DuroMax XP4850EH’s important features:

  • Product weight: The DuroMax XP4850EH Dual Fuel Hybrid Generator weighs 122 pounds.
  • Product dimensions: This dual fuel hybrid generator’s dimensions are 25″ L x 24″ W x 21″ H.

  • Windings: The generator’s windings are made completely of copper. This is one of the best things about XP4850EH’s construction! The copper windings hold up a lot better than the cheaper aluminum ones do.
  • Construction: The unit’s body is made completely of metal. This durable construction will prolong its life. You can expect it to last for the long term, even when it’s used on rougher job sites.
  • Gas tank volume: If you don’t want to use propane, the unit’s gas tank volume is 4 gallons. This large fuel tank capacity is convenient, so you won’t need to refill the fuel tank constantly.

Do you have a question or two about how this unit works? Learn more about its specific functions below:

  • Surge-arrest: Power surges are not to be taken lightly. If you don’t have the right protections in place, your appliances can overheat and become damaged. Luckily, the XP4850EH comes with a surge-arrest feature. This will protect your investment from a destructive surge.
  • Low oil shut off light: Your generator can’t run on propane or gasoline alone. It also needs oil. If you run your generator with a low oil level, it may break down. To avoid any issues, the XP4850EH comes with a low-oil shutoff sensor. This protects the motor and keeps it running for the long term. The sensor is automatic, so you will never have to give your oil level a second thought. Just add more when the indicator light turns on.
  • 7HP air-cooled engine: The unit’s 4-cycle air-cooled engine is a hardworking machine. It provides optimal power that can handle multiple jobs. Use this generator to power heavy-duty power tools and high-voltage appliances.
  • Optimal power: The XP4850EH provides 4,850 starting watts. If this wasn’t enough, it also packs a punch and will keep you powered with 3,850 running watts. Don’t worry about this product being unable to handle heavy loads. It can operate refrigerators, lights, air conditioners, and other appliances you have on hand.
  • Fuel gauge: You can quickly assess the generator’s gas level with the easy-to-read, built-in fuel gauge.
  • Comprehensive power panel: This generator’s power panel has a good selection of outlets for optimal compatibility with your appliances. It has one 120 240V 30A twist lock outlet and two 120V 20a household GFCI outlets. It also has 12V DC charging posts you can use to charge external batteries.
  • MX2 technology: The MX2 technology on this generator helps you get maximum power for each 120-volt receptacle. You can choose between operating the generator at 120V only with full power or at 120V and 240V at the same time.
  • Additional features: This dual fuel hybrid generator comes with additional accessories like a funnel, wheel kit, propane hose, tool kit, and battery charging cables. It also has a handle you can use to wheel the unit around easily. The handle conveniently folds down out of the way when it’s not in use.

Pros & Cons of the DuroMax XP4850EH

Equipment, Wood, Machine, Industry, Saw

As with any generator on the market, the DuroMAx XP4850EH comes with pros and cons. Here are some of the positive and negative aspects of this product:


  • Dual fuel technology: One of the DuroMax XP4850EH Dual Fuel Hybrid Generator’s biggest perks is how you can use either propane or gasoline to power it. You can use either fuel type (gasoline/propane) to operate your appliances reliably.
  • Long run time: This generator has a generous run time. Depending on the fuel source and load you use, the exact run time will vary slightly. For example, it can run for up to 8 hours on a 1 2 load of gasoline. On a 1 2 load of a 20lb propane tank, the generator can run for up to 9 hours.
  • Durable construction: The DuroMax XP4850EH was not made cheaply. Its body is constructed entirely with metal, and it features high-quality copper windings. This unit is well-equipped to withstand outdoor use.
  • Simple to use: This generator was designed to be simple to operate for any user. You can turn it on with the electric start button or use the more standard pull-start mechanism.
  • Includes accessories: With your purchase, you won’t receive just the generator. You’ll also get extra accessories like an oil funnel, spark plug wrench, toolset, wheel kit, and DC charging cables.
  • Noise levels: The DuroMax manufacturers had noise reduction in mind when they designed the XP4850EH. During use, the OHV engine holds a constant RPM level, which helps reduce noise. The built-in muffler also helps the unit run quieter.
  • Smooth operation: This generator sits on a frame with four isolated motor mounts. This setup allows the entire generator to run smoothly on uneven terrains and in windy conditions.


  • Maneuverability: This generator is technically “portable,” but this is a very loose description. It weighs more than 120 pounds, so it won’t be easy to lift and transport. This is unavoidable with generators of these capabilities. It is, however, situated on a set of wheels for easy ground-level transportation.
  • No remote start: Some generators have an option to turn them on remotely. Unfortunately, the DuroMax XP4950EH doesn’t have this capability. This may be inconvenient when you are working on a large job site, as you will have to walk up to the generator to turn it on and off.

Looking for a Generator with an Electric Start?

A big question you might have when shopping for a generator is likely: How will I turn it on and use it?

This DuroMax 4 850 Watt Dual Fuel Hybrid Generator was designed with the average user in mind. It doesn’t require any excessive force or complicated techniques to turn on. It’s as easy as starting your car! It has a refined electric starter function with a simple on/off switch.

Even though this generator is start-type electric, you can still opt to turn it on with the traditional pull-start mechanism.
