How Long Can Your Generator Run Continuously? – Tips

Generators are incredible machines that supply power. How many times do you experience blackouts? Well, if you are going through such situations, then consider buying a generator. No one in the current generation would want to go on without power supply.

Power covers our entire daily activities. Besides, this machine can achieve a significant number of events in supplying energy. Additionally, it is portable so that you can move it around even to outdoor activities with no power supply. The most asked question among customers is How long can it run continuously? Let’s have a look!

Below are some essential factors that determine how long it can run

It is a hard question to answer, as it depends on several factors. Nevertheless, In most cases it bases on the kind of generator you are using and the type of fuel it consumes. Check out the factors and how it affects the way the generator runs.

Standby generator

It is the most common type of generator that cuts cost-effectively. It greatly determines how long you will continuously run it. If you intend to run it consistently for a couple of days, then you should consider standby rather than portable ones. It is because such standby machines have features such as motors that work to withstand frequent use.
