Top 6 things to consider when portable generator

First, we give the criteria that were used to determine the three best longest-running generators.

1. Price.

Generally, portable generators are expensive. However, there are generators that are a bargain. They are sold at a lower price but offer a quality service.

2. Size.

The size will influence the portability of the generator so most often a good generator should be lightweight but still offer a quality service.

3. Ease of use.

An easy to use generator should be easy to start and stop even for a person with less knowledge on how to use a generator. It should have a power off and on a button.

4. Running and starting watts

A generator with a higher running and starting watts could power on a lot of appliances as compares to the one with lower appliances.

You should note that generators especially portable generators are limited to the number of appliances it can power on.

This number of the appliance depends on the running watts and starting watts.

5. Noise.

Generators produce noise while powered on. This is why they are always put a distance away from your house.

But there are generators in which the noise is significantly low.

You wouldn’t like a generator that produces noise to an extent you have to shout to speak to one another.

6. Durability.

For every appliance, you buy you want to avoid coming back to buy a new one after a short period of time. Generators that are durable are generally preferred.
