Buyer’s Guide

dual fuel generator

If you want one of the best dual fuel portable generators on the market, there are several considerations you need to pay attention to. It doesn’t matter whether you are looking for a generator for tailgating, camping, for your RV, or other needs, the following are some of the things you should look for.

Power Needs

One of the most important things to consider is your power needs. For instance, the type of electrical appliances you have greatly influences your choice of dual fuel generator. If you don’t have a refrigerator, a cooker, and a range of other power consuming products available, you don’t need a high power dual fuel unit. Choose one that is ideal for all your needs.

Is It Fuel Efficient?

The last thing you want to do is buy a machine that consumes more fuel than you can afford. If you spend a lot on gasoline or propane for your unit, it is not worth having. Choose one that is highly fuel efficient. It should be economical, energy saving, and with a consumption rate of 8 hours or more on a full tank with half the load. Anything less than this might cost you more than you can imagine, especially if you are planning to use it a lot.

Is It Durable?

Any generator termed ‘best dual fuel generator’ should last at least 6 years. The durability is determined by the overall structure and the engine. The amount of horsepower determines the load the unit will be able to carry. The most preferred types of engines are the OHV types. While considering durability, ensure that it comes with a metal frame that protects the tank and the unit itself.


While you are in the market to buy a generator, ensure that it doesn’t weigh so much that you are unable to lift it off the ground. It should have wheels to make movement more convenient. While you’re at it, consider the measurements. It shouldn’t be so bulky that you can’t place it anywhere you want.


Noise is annoying, if not for you then certainly for your neighbors. Consider the decibels the unit you are purchasing has. There are some that are considerably quiet. Aim for those types of generators.


The preferable type of generator is those with electric starts. Compared to the conventional pull types, the simple touch starter is best. It should be convenient for most of your household appliances. However, there are times when both start types come in handy. Should the electric start fail, the pull start is helpful.
