Honda - EB10000 Industrial Generator

Within the 10000 watt generator market, Honda has an excellent reputation for producing portable, durable and reliable motors, and the Honda EB10000 is no different.

While it can be used for residential and personal purposes, the hardy-nature and sturdy materials this generator is made from make it perfect for commercial use too, especially on construction sites as it’s OSHA worksite compliant.

Saying this, the generator does weigh more than 400 pounds, so we wouldn’t recommend this model to anyone hoping to lug it around with them on a daily basis.

Despite being one of the heavier 10k generators out there, this model is very fuel-efficient for its size and power output, running at seven hours on a 50% load.

A handy 8-gallon fuel tank also means you won’t have to think about refueling this generator all day long.

It’s also surprisingly quiet, thanks to an in-built muffler, silencing the noise levels to the same as a vacuum cleaner!

10000 Watt Generator Buying Guide

Inverter Vs Standard

Choosing between a 10,000 watt inverter generator and a 10,000 watt standard generator is a common problem for big-generator buyers. While standard generators used to be the popular choice, inverter generators are beginning to take over. 

Generally speaking, inverter generators are smaller, lighter, and have lower noise levels compared to standard generators. They’re much more high-tech in that they can convert DC power into AC power while retaining a high frequency. 

Doing so, they get rid of any power fluctuations that are so common in standard generators and provide a more reliable power source. 

What’s more, standard generators work at a constant and non-adjustable speed, expelling unnecessary energy and using excess fuel. On the contrary, inverter generators can adjust their speed according to the appliances that they are powering. This makes them much more fuel efficient and environmentally friendly.  We’ve created a separate guide on best inverter generators that you should definitely check out and learn more about them. 

Fuel or Solar

Generators are typically powered by fuel, whether it be diesel, propane or a combination of both. In recent years, however, there has been a new wave of 10000 watt solar power generators appearing on the market. As well as being much more environmentally friendly, solar-powered generators are generally much smaller, and easier to transport around. 

They do have their disadvantages though. Solar generators generally have a much lower power output and struggle to power things as large as a home. They are also much less durable due to the batteries that hold and power them. 

Diesel

A 10000 watt diesel generator is usually the generator of choice for those looking for a high powered, reliable, and durable generator. Unfortunately, you may find that diesel generators are banned in your neighborhood due to their high-emissions. You’ll want to check out the latest regulation before you invest your money into one. 

Propane

Another common type of generator is the 10000 watt propane generators. Over the years, propane, otherwise known as LPG, has overtaken diesel generators in the market, thanks to their clean emissions. They also have an impressive shelf life and are easy and safe to store. 

Dual Fuel

You’ll also notice a number of 10000 watt generator dual fuel options on the market to choose from. This unique feature allows them to run on both propane and gasoline, and owners can easily swap to use either with the flick of a switch. 

A huge advantage of investing in a dual fuel generator is that the user can choose the fuel type depending on the use and conditions you find yourself in. 

Noise Level

With a generator as powerful as these, you cannot expect to find a silent-operating generator on the market. You will, however, find quiet 10000 watt generators that function at a much lower noise level than others. This is particularly useful if you’re using them in a residential setting or to power your RV at a small campsite.

The quietest 10000 watt generators operate at somewhere between 72dBa and 75dBa, though you may be happy to go as high as 80dBa if your neighbors are a fair distance away. 

Portability

In certain situations, you may want to have the option of transporting your generator around with you. For this, you’ll find that the 10000 watt portable generator will come in handy. 

As one of the most powerful generators on the market, finding a small and lightweight 10,000 watt generator can be tricky. But it is possible. However, it is more common that higher powered generators are standby versions, that you can’t move. If you are more interested in something like that, check out best standby generators

Many have good quality wheels attached and fold down handles to help improve the portability of the generator. 

Other Features to Consider 

Fuel Tank Capacity and Runtime

As you’d expect, the larger your generator’s fuel tank, the longer you’ll be able to run it without having to refuel. This may not be a problem for you if you’re only using the generator in small bursts. However, if you want to use the generator for more significant periods of time, i.e. 8+ hours, then you’ll want to consider a larger tank. 

While an eight-hour runtime is generally considered to be good, there are some slightly higher-end 10000 watt generators that will run for up to 12 hours on one tank.

Outlets

10000 watt generators tend to come with numerous outlets, and you’ll want to make sure these outlets are suitable for your appliances. Most are equipped with a combination of:

  • 120V household outlets,
  • 120V 30A outlets,
  • 120/240V 30A outlet,
  • 120/240V 50A outlet,
  • 12V DC outlet.

Rated and Maximum Power Output 

Each generator will have a rated power rating which describes the amount of power that the generator can handle under a normal load. If you feed the generator more power than this, you’re likely to overload the engine and cause the generator to malfunction. 

As well as this, each generator will have a maximum or peak power. This relates to the additional wattage that the generator uses to start up, or sometimes when it’s at its highest level of consumption. A generator will only be at its peak power for a couple of seconds. 

Pricing Range

Generators of this size are never going to be cheap, but they do come in at a range of prices. It’s unusual to find a 10k generator for less than $500, especially if you’re looking for one that runs well and one that will be with you for a long time. 

As a general rule of thumb, generators with more features and more power will cost the most, with the most expensive 10000 watt generators costing upwards of $5,000.

Frequently Asked Questions
