A Quick Buying Guide to Choosing the Best Dual Fuel Generator

An inundated market for sure, choosing the right dual fuel generator is another story – one that needs to be taken seriously if you’re only after for an exceptional dual fuel generator. As I’ve mentioned previously, all the dual fuel generators out there can only be beneficial once they’re based on your specific needs.

As such, it’s crucial that you’re able to ascertain its use first so you can establish which of the product’s characteristics should work best. Below are the factors that you have to keep in mind:

#1 The Noise Level

Power generators have always been synonymous to producing noise. And while that may be bothersome for some, the level of noise that comes from them can be quietened depending on your knowledge on how to perform such task.

In this regard, it’s important to know that some dual fuel generators produce more noise than their counterparts. For your peace of mind, ask the retailer which of them produces less noise.

#2 Power

The product’s engine is considered as a vital consideration. As such, if your house has a particularly large supply, choose a generator that comes with a high power output or an engine that can accommodate the wattage requirements.

While we’re at it, it’s a must that you consider the wattage requirements as going otherwise may render your generator to be both less efficient and functional.

#3 The Ease of Use

Like most equipment of this caliber, it’s also vital that you take into account the generator’s overall user-friendliness. The last thing you’d want to have with a hefty equipment is something that has a complicated operation.

Of course, no one would also want to operate a tool that can be quite difficult especially at a time of a crisis such as power outage.

Portability can also be considered under this factor. If you’re the type of user who’d like to relocate it occasionally due to some recreational activities, then by all means, go for a portable one.

#4 Versatility

A good dual fuel portable generator should allow its users to switch between gas and propane with much ease. Go for a product which is equipped with a fuel selector that enables you to switch between fuel sources safely and quickly.

Both gas and propane have their respective advantages. The former is deemed to be the least expensive among its counterparts and can be purchased at nearby local gas station.

Meanwhile, the latter is known for its longevity but is still available for refill despite days of power outage. In the event that a certain fuel source is not available, you may still get to have a more usable alternative.

#5 The Size

Size is paramount especially if you’re after the product’s weight, portability, and its total wattage. This along with the factors mentioned should contribute to how your dual fuel generator is. Factoring the size of the generator is therefore important right before you make that purchase.

#6 Portability Versus Non-Portability

Virtually all generators today suit a certain outlet type. They can also be categorized between portability and non-portability, two of which should be determined depending on your needs. Whether you’re up to run them both through just gas or propane and gas.

These details are considered important if you want to make the best out of your generator.

#7 Your Budget

Last but certainly not the very least is your budget. As these generators can be truly on the more expensive side, it’s simply crucial that you consider investing on the right product wisely. As it goes with most of your purchase, knowing exactly the scope of your budget should make this experience much easier and more informed.

Now, if your budget falls on the “generous” side, ensure that you choose only the best features that suit your needs. But if it falls on the “strict” type of budgeting, make certain that this product is enough to accommodate your needs accordingly.

On the other hand, take note that not all expensive products can be considered as good ones. My advice? Be very keen with your chosen product’s details and features. Also, be inquisitive enough to verify this information from your retailer. 

The Verdict

The Standout: The DuroMax XP4850EH 3850 Running Watts/4850 Starting Watts Dual Fuel Electric Start Portable Generator.

There is much to be found when you go for the DuroMax XP4850EH. The vital features that everyone should be looking for are there to be experienced.
