This generator further shows Champion is closely following the current market trends as regards which outlets consumers are looking for in their generators.

The Champion 15000 Watt Generator features different outlets, all of which come protected with plastic, snap-in protective covers that are a great addition, particularly on dusty job sites.

The manufacturer is known for building some of the most durable and reliable generator sets, which are used commercially & residentially.

So, the XP15000E is a great option when it comes to a high-powered generator, usable both at home and on the job (construction) site.

Power

The Duromax model‘s 713cc V-twin engine puts out 15,000 starting watts & 12,000 running watts. The engine supplies 23HP (horsepower), with an operating volume of 74dba, and that’s pretty standard for a good number of generators.

It’s built to cater to heavy loads from construction or residential refrigerators, lights, home air conditioning units, in addition to power tools that have high amperage ratings.

Considering this, you need not hesitate to rely on the XP15000E for your home backup power, along with complete RV electrical reliance, or for powering your whole job site.

Outlets

In the outlet selection on the Duromax XP15000E, we’ve got a lot of options to use the full 12,000 running watts.

Though covered outlets would be a cool option to see, the number of outlets on the unit compensates for this small drawback.

On the model, you can pick from one 120V 30A twist-lock outlet, one 120/240V 30A twist-lock outlet, four 120V 20A GFCI outlets, and one 120/240V 50A heavy-duty outlet for RV use.

Since there are so many various outlets to select from, you won’t face any issues about plugging up just about any equipment or appliance to the generator.

Runtime and fuel capacity

It comes with a 10.8-gallon fuel tank, allowing for up to 8.83hrs of use at 50 per cent load.

And this is an excellent runtime because it’ll enable you to enjoy a full day’s worth of power from this unit without the need to worry about refilling it.

Key features

This generator doesn’t offer any extraordinary key features, but it does give you the benefits of surge arrest & a digital multimeter, enabling you to monitor the vitals of your generator.

Just like the majority of larger-sized generators, the Duromax XP15000E is equipped with wheels and collapsible handles. These aid easy transportation.

Duromax XP15000E PROS

Northstar Generator 15000

The Northstar 15000 Watt Generator is also one of the best 15000-watt portable generators.

With its price in the higher range, let’s see how it’ll compare with some of the other options above.

Power

The portable generator provides 15,000 starting watts & 13,500 running watts via its Honda GX690 OHV engine, delivering 22HP.

The running watts are slightly higher compared with the majority of generators on this ranking, making it perfect for users in need of a bit extra wattage throughout the runtime.

With the Honda engine, you can have peace of mind that you’re using a dependable machine since Honda is famed for its superb engines.

Outlets

As regards outlet selection, this generator really beats the competition as it features 11 outlets for you to pick from.

Though they’re not covered with protective outlets, the offerings are still impressive.

The unit has a control panel, packed with eight 120V household outlets, one 120/240V 50A outlet, one 120V twist lock, and one 120/240V twist lock.

The eight household outlets are quite unique, allowing you to plug in up to 8 various small appliances to be run at the same time.

Runtime and fuel capacity

The Northstar 15000 packs an 11-gallon fuel tank, allowing for eight hours of runtime at 50 per cent load.

This is slightly less efficient compared with most of the generators above. However, it still offers a full workday’s worth of dependable power.

Key features

Here are some of the cool features to expect on this generator: premium 100$ copper-wound generator head, an ultra-quiet muffler, vibration isolation mounts, in addition to a variable timing digital CDI ignition.

Verdict

This model is sold at nearly $1,000 more than several of the other similar generators. But we’re not really sold on the additional cost.

While the outlet selection and a 4-year warranty are a great upsell, for this amount of money, we’d have expected a bit more features to make the extra cost justifiable.

  • Expensive
  • Wheel kit not included

As earlier promised, in this section, we take a look at a comprehensive buyer’s guide to help you find the best generator to buy.

Type of Generator

First note that 15000kW generators can either be portable or a standby unit, and the major difference is that portable generators can be transported easily as nearly all of them feature wheels and handles.

On the other hand, a standby generator is a one-spot-installation machine, which, once installed, cannot be moved unless you’re relocating it.

Furthermore, standby generators are generally extremely powerful and highly responsive.

Also, they’re automatic so there’s no need for you to start the generator. But they’re quite costly.

Dual-fuel and single-fuel generator is another category. A dual-fuel generator will offer you the freedom for choosing between the fuels it’s compatible with, either gasoline or propane, propane, or natural gas.

For this reason, you need to ensure the 15kW generator you opt for runs quietly.

But if you’ll be running multiple large appliances, such as microwave and electric oven at the same time, then you’ve to check to see if 15kW power will be enough.

Consider adding all the wattage of these appliances to determine the value of required wattage. And bear in mind that starting power is nearly double the running power.

Durability

What are the generator parts made of, and are the materials durable?

You’ve to make sure the generator you choose to buy is designed using high-quality materials, which can resist corrosion and rust and also give the best durability.

Make sure the whole construction is something reliable & robust, having a strong protective frame.
