Duromax Generator Reviews – A Reliable Budget Pick

Updated On: September 13, 2020
By

If you are searching for a sturdy, good-performing, and portable generator, one of the best brands to consider is Duromax. While this is a fairly new brand founded in 2003, it has managed to get a seat at the table of industry leaders.

So, what makes Duromax generators worth their salt?

First, this brand specializes in manufacturing portable generators. By specializing, it has perfected its game to come up with a comprehensive lineup of “specific” and top of the line machines.

The current achievements of the brand remain a far-fetched dream for the majority of brands that fall under “jacks of all trades.” As you will find out in our Duromax generator reviews, this brand has a whole assortment of portable generators from digital inverters to heavy-duty hybrid units.

How to Choose the Best Duromax Generator?

One thing that genuinely gives Duromax an edge above the competition is the quality of its engines. These motors are well-engineered for maximum efficiency and durability. However, different models from the brand will also have several different traits that make them ideal for specific applications and unsuitable for others.

Here are aspects that must not escape your mind before purchase.

Type of Generator

Even though Duromax specializes in manufacturing hybrid dual-fuel generators, it also makes models that are primarily gas-powered. Machines from the brand fall under two main categories:

Inverter Alternator Generators

These are machines packed within a noise reduction casing. They are more compact and lightweight, and they also tend to be more fuel-efficient and quieter than conventional generators.

Conventional Alternator Generators

These are machines that feature an open frame. Even though some models are quite bulky and heavy, they are technically portable because they often feature a wheel kit that is sold as part of the package.

One of the bragging points of the conventional alternator generators is that they provide more power, and they also tend to be cheaper. On the downside, they are louder than their inverter alternator counterparts.

Engine Capacity

The engine capacity of a generator plays a leading role in dictating the amount of power that can be generated. When an engine is rated “440cc,” for instance, the cc refers to its engine capacity.

On the other hand, OHV (overhead valve) means that the engine can make more power while OHC (overhead cam) signified better fuel efficiency.

In this example, 440cc is the amount of power that can be produced, and OHV/OHC indicates how this power is handled.

Starting and Running Watts

It is also imperative to understand the starting and running watts of a machine. Typically, larger appliances and tools require more wattage to start. For instance, a 10000BTU air condition that runs on about 1200 watts may need around 1800 watts to start up.

The heavier the motorized equipment, the higher the starting wattage that is required. To get it right, ensure that your generator of choice can provide not just the power needed to run your appliances simultaneously, but also the starting power required.

Outlets

Duromax generators have several power outlets. Standard portable units often have two standard outlets that allow 120 volts and 20 amps. Bigger and more powerful models can have 240-volt/ 30-amp or 120/240-volt /50-amp outlets. Some machines also come with unique power outlets that make them RV ready.

The XP10000EH is a big blue and black beauty that stands 27.5 inches high, 40 inches long, and 29 inches wide. Even though it is not as big as the DuroMax XP15000E, this machine is pretty heavy, and it weighs a staggering 232 pounds. Well, the whooping punch delivered was just as we expected.

One of the downsides of choosing a big and bulky machine is that while it may provide the power you need, moving it may be a nearly impossible task. Fortunately, this unit is portable because of its handle kit, as well as its never-flat tires.

To fire up the engine, you can either use the recoil starter or flip the electric switch. What came to us as a complete surprise is that this is a fairly well-mannered beast that is not as noisy as we expected.

It produces a mere 72 decibels, so you don’t have to worry about getting into loggerheads with your neighbors.

Apart from its outstanding performance and power capacity, this unit also offers you a generous fuel capacity of 8.3 gallons. With gas, it can run uninterrupted for 10 hours at half load. In case you choose to use propane, the generator can run continuously for 8.5 hours on a 40 lbs. tank.

Pros
  • Dual fuel hybrid generator
  • 18HP, 440cc OHV Engine for outstanding power
  • Easy to use control panel
  • Quiet for its power (72 decibels)
  • Wheel kit for better portability
  • Decent runtime
Cons
  • No remote start

If you are looking for a generator with the capacity to work hard to meet your power needs, here is a model that must not escape your attention. It is one of the biggest units from Duromax, yet it still fits in the portable generator product line because of its wheel kit.

With the 500cc and 20 horsepower engine, you will have adequate power to keep your home and workshop appliances running as usual, even during harsh storms.

This is a beast that allows you also to plug in heavy and energy-thirsty machines without a problem. It has a surge power of 13,000 watts and continuous power at 10,500 watts.

With this much power, you are likely to assume that the noise produced is maddening. Well, you are mistaken; the sound levels are rated at 74 decibel, which is merely as loud as your hairdryer. The in-built muffler does an excellent job of tamping down both emissions and noise.

Another area where this machine excels is its fuel consumption. It has an 8.3-gallon fuel capacity and can run continuously for around 8.5 hours. For enhanced fuel efficiency and also for an extended lifespan, this generator is designed to automatically go into idle mode when no appliances are plugged in.

The XP13000E brags of a full-featured control panel with five outlets that allow you to power a range of tools and appliances. What’s more is that this machine will enable you to use 120V and 240V at the same time or 120V for full, dedicated power.

If you are searching for a high-powered generator capable of powering just about any home appliance, consider the Duromax XP13000EH. Although the upfront cost of this model is not on the lower end, it features a powerful 500-cc OHV 20-HP engine that assures you of an excellent return on your investment.

For this option, you get a starting power of 13,000 watts and 10,500 watts continuous power. This is also a hybrid dual fuel machine that operates on gasoline or propane.

The unit can offer about 8.5-hour runtime with an 8.3 gallons fuel capacity at 50% load, with a consumption rate is reasonable at around 0.98 GPH.

With propane, the runtime is lower at 3.5 hours at half load. The propane consumption rate is also high at around 1.34 GPH on a 20 lbs tank. On the bright side, the premium engine comes with several outlets for powering all sorts of home appliances and power equipment.

It’s easy to tell that this is a powerful, heavy-duty generator with an all-metal construction. This is a deliberate design that ensures it lasts longer, even on the most rugged job sites. Unfortunately, this 260 pounds beast makes the wheel kit a little challenging to use. It is more convenient to set it in a stationary position.

For smooth operation and safety, this unit features a recoil start as well as an electric start. Another practical feature is the oversized noise-reducing muffler, although it does not prevent the noise levels from getting higher than 74 dBA when the unit is overloaded.

Pros
  • Powerful 500-cc OHV 20-HP engine
  • Several accessories included
  • Electric start and recoil starter
  • Considerably quiet for its power (74 decibels)
