To find the best portable generator you can, you have to look out for a few things. Firstly, the size of the generator is essential; it has to fit into your desired place. For instance, if you want to use the generator at home then it has to be as small as possible. Otherwise, it will take up a lot of space in your backyard or garage. On the other hand, if you intend to take it with you while travelling, you will need a larger one.

In addition to the size, you also have to think about how many amperes you will be getting per kilowatt-hour. You should also consider if you want a direct current (DC) or alternating current (AC). Some types of portable generators even come with seven ports in them. If you run out of power and plug in the remaining seven ports to an electric source such as an automobile alternator, you will end up with a constant power source all throughout.

The second thing that you need to check is the battery management system of the generator. It is advisable that you buy a system with a high level of battery management. For example, the best generator to buy has a high battery management system that enables you to regenerate the DC power outlet when the battery gets low. This way, the power supply for the DC power outlet remains constant even when the battery goes below the critical point.

The third factor that you should check is the max power capacity of the generator. The max power capacity of the generator is the maximum capacity of the batteries that can be used at the same time. This means that you will have to get a larger battery for the same amount of DC power output. For example, if you buy a generator with a DC power output of 100 watts, then the battery must be able to support at least that much DC power output before it starts suffering from voltage degradation.

The fourth thing that you might need to check while buying a portable generator is its size. There are two types of generators available: those that have a long cord and those that have a short cord. A long cord type might aid you to keep the generator close to your location where you will be using it most. However, you would need to keep careful watch over its movement as you move from one place to another.

On the other hand, the shorter the cord, the more portable it can be and the more DC power it can produce. You will thus need to choose a DC power generator that will not make your home or your office premises stand a chance of being polluted. In case the DC power generator produces more DC than the power requirement of your appliances and electronics, then this could constitute nuisances. Also, if it exceeds the DC power capacity, then there is a possibility that it might overload your appliances and create a huge loss for you.

So, in case you are planning to buy a portable generator that does not come with a cord, then make sure that the one you are going to buy will not constitute nuisances. It would be preferable if you buy a cordless portable generator. One more important thing that you must check while purchasing a portable generator is the maximum power capacity of its batteries. The more the DC power capacity of the batteries is, then the lesser will be the amount of DC current it can possibly produce, and the more dangerous the situation might become for you.

The last but not the least important thing that you must check while purchasing a portable generator is the quality of its power source. Make sure that the portable generator you are about to purchase has got a steady power source that will not fail to supply its required current even during extreme climatic conditions. In case you want to purchase a unit that comes with a lithium-ion battery status, then it would be preferable that you check whether the unit comes with an AC to DC converter or not. A device with a lithium-ion battery status will be much safer than one with a DC to AC converter, and it will be much easier to replace a dead battery of a portable generator with a new one as well.
