8 Best Dual-Fuel Generators: Run on what you have

Electricity is an integral aspect of our lives, as we need it for almost every task. However, what happens when there is an unannounced abrupt power outage? Our plans are on hold, and we would need to wait before electricity is restored, then we can go about our paused task. A good number of times, this is annoying.

However, when you have a back-up power source, you have little or nothing to worry about. There are lots of alternatives suited for this purpose, but laying your hands on a dual fuel generator could be the best choice you ever made.

Basically, a single fuel generator operates with one type of fuel only, while a dual fuel generator allows you to use either propane or gasoline, depending on your choice and availability. You can decide to switch between propane and gasoline in a bid to prolong the runtime, with this back-and-forth option, you can use power whenever you need it.

Having the best dual fuel generator is satisfying and saves you lots of stress, irrespective of the location where you intend using it. It is also awesome for people who reside in remote areas, and generally, they come with a mobility benefit which allows you to enjoy its operation for 24 hours or more without having to refuel.

If you have plans on using your generator for emergency purposes, then the privilege of choosing the fuel type is a profound benefit. Unlike gasoline, propane can be stored for a long period of time, and this makes it a suitable emergency fuel, because it can be stored for years, without degrading. It is also very easy to get propane during emergency periods because they are kept in individual containers.

One of the best merits which a dual-fuel generator gives you, is the flexibility which it gives you to choose the fuel you want. If you are working on a task which does not need much power, then you can save money and opt for propane because it is more affordable.

However, if you need your entire home to be powered in case there is an unexpected power outage, then you can opt for gasoline, and your dual-fuel generator would work just fine.

One important feature which you need to bear in mind before opting for any dual-fuel generator, is having a conventional idea of what you will plug into the generator. There are various plugs for different tasks. If you want to power small appliances, using USB ports and few standard outlets would come in handy.

If you want to power the whole home, then you need a model which comes with lots of outlets. It is advised that you confirm if the outlets are GFCI certified, so that you can be assured that they can effectively handle your power requirements.

The amount of power needed is based on the number of equipment which would be in operation at a particular period of time. Hence, it is safe to say that, having more than the needed power potential is better than not having enough. The measurement of the potential power of the dual-fuel generator is measured in watts, and it can be found on each product’s specification.
