Duromax Generator Buying Guide

Inverter Or Standard

The difference between inverter or standard generators depends on the electricity that is being produced. 

Standard generators only produce AC electricity while an inverter generator produces electricity in three phases: high-frequency AC to DC back to a stable AC current. 

Buying a Duromax inverter generator is more advisable over going for a standard one. The advantages of buying an inverter are numerous and will make a huge difference to your usage.

Firstly inverter generators produce a reliable power that is not solely based on engine power, so the power is considered to be cleaner. Secondly, the inverter generator produces a power that is more or less the same quality as your own electricity supplier.  

The versatility and reliability of the power generator by inverter motors makes them more appealing to a modern buyer and the market has started to cater to this demand. This is why you’ll see a lot more of them available than a standard generator. 

Saying that, Duromax has a wide range of both standard and inverter generators, so finding the right one for your uses should be a breeze.  

Fuel Type

Diesel

The use of diesel in generators has become commonplace in the modern market, and there are many advantages to using a diesel-powered generator over any other fuel.

The safety element of using diesel fuel is a massive draw for many, as the fuel is the least flammable out of them all. Diesel is also the easiest fuel to obtain, especially as it is the choice of fuel for the military, ensuring a steady supply. If you are using your generator during a natural disaster or power cut, this easily obtainable fuel may be your saving grace.

Generally, the cost of running a diesel-powered generator is also cheaper, making this choice of fuel popular with the economically minded. The general rule of thumb for fuel consumption is 7% of the rated generator output. 

The disadvantages of using diesel-fuelled generators include something known as wet stacking. Wet stacking is where the generator has been run on low power for too long and smoking can occur. Counter this by running a heavy load now and again.  

Propane

The use of propane fueled generators has become more popular over the years and has even given birth to a range of hybrids, and in particular, the Duromax propane generator. 

The advantages of using a propane fueled generator include the following. The easy storage nature of propane makes it appealing as propane’s shelf life is particularly long. 

Propane is also easily obtainable during power outages, as gas stations may be unable to pump fuel during an are wide outage. 

If noise levels are something you are considering when buying a generator, then propane may be the way to go as propane fueled engines are generally a lot quieter when running.

The main disadvantage of using a propane-fueled generator include its cost. Propane can be an expensive fuel to buy, so it is important to check prices in your local area before you commit to buying one. A propane run engine also has a shorter life span compared to diesel-fueled ones. 

Dual Fuel

The Duromax dual fuel generator is becoming a popular choice with shoppers, mainly down to their reduced running costs. It’s also seen as the environmentally-friendly option compared to generators powered by gas and diesel. 

Running on LPG, or liquid petroleum gas means that the duel fuel generator does not have to solely rely on gasoline. 

This versatility also puts owners in a better position when in a moment of crisis. If you can only obtain one fuel and not the other, you won’t be left in a situation where you can not run your generator. They are also seen as more efficient machines, outputting far more power than standard fueled generators.  

The initial purchasing of a duel fueled generator can be a little expensive. This being said, we only advise you to opt for a dual machine if your power demands are high.  

Power

Understanding how much power you need from your generator all depends on what you are using it for. If you require a generator to back up the entire house; running lights, fans, TVs, refrigerators, and so forth, then it is better to opt for a lager 10,000 watt generator.

Anything under around 5,000 watts will often be unable to run an entire household and is reserved for smaller undertakings. If you wish to power only the refrigerator or basement freezer, maybe only enough to keep the lamps on, then a less powerful 5,000 watt generator is more than up to the job. 

A simple rule of thumb is to up your wattage needs by 2000. For example, if you find the total wattage for the items you need to run as 10,000 watts, you should consider getting a generator capable of handling at least 12,000 watts to be on the safe side.

Size

Physical size is not always a credible insight into the power of a generator, and many small Duromax generators can still pack an almighty punch when it comes to wattage and output. 

Smaller generators have the appeal of being super mobile, and if you are using them for boosting your power tools at work or at home, they can follow the job everywhere. 

When we consider size in the sense of its outputting ability, it is then important to understand your size in power when you wish to power the entire house for example. If your generator is too small, then you will force it to supply more power than it is capable of doing and eventually overloading the circuit. 

We would recommend that you speak to a qualified electrician before installing any generator, especially if you are unaware of the correct procedures.  

Portability

In this fast-paced world we now live in, mobility is a massive factor when buying most devices. 

When it comes to portable generators, size isn’t everything. There are many portable generators out there on the market with wattage ranging as high as 7,500 – powerful enough to run numerous household items. 

The Duromax portable generator has peak watts at around 5,500 and running watts around 4,500, proving the mighty power of mobile generators.

The advantages of having a portable generator are only recognized if your reason for buying one is to be mobile. 

If you’re taking your generator on a camping trip or from building site to site then the investment in a portable version is rewarding. If, on the other hand, you’re only purchasing a generator for home use, then portability may not be of interest. 

Many portable generators, the Duromax portable generator included, come with wheels attached. This added feature makes moving even the heaviest of generators easy.      

Pricing Range

When it comes to generators, the price varies greatly depending on the type of generator it is. Home standby generators are the real deal and should only be installed by professionals and can cost anywhere between $3,000 and $6,000. 

Portable generators sit at the other end of the pricing spectrum, with low power but great mobility. These generators usually market for between $400 to $1,000. 

Inverter generators boast a little more complexity to their makeup, which does have an affect on their pricing. Costing around the $500 to $4000 mark, it’s not hard to find an inverter generator to suit your budget.
