For example, a battery powered generator might last only 3 or even up to 12 hours when the load is being supported. For instance, suppose you have a 1000-watt generator and are running 500 watts of load then the generator burn for around about 10 hours. Power consumption increases when two devices with high wattage are running at the same time, hence the length of time can be greatly shortened.
Things like the capacity of the battery and how efficiently you use that energy, for example, kind of go to determine your run time. In addition, newer generators boast lithium-ion batteries that have increased capacity and last longer than their more diminutive ancestors. Lithium-ion batteries, for example, have a lifespan of more than 2,000 charge cycles which means that when used under normal circumstances will last several years.
Emergencies and Recent events like the extreme weather disasters which have led to widespread power outages put safe, reliable battery powered generators in extremely high demand. Local news reports said families used them to power refrigerators, medical devices and phones during a hurricane.
As Thomas Edison put it: "Many of life's failures are people who did not realise how close they were to success when they gave up." It resonates even better when we are talking about battery powered generators in as much as there are a lot of benefits from the latest technological innovation of a human to make life comfortable again without disturbing the nature but with a realization that I can survive too.
The wattage offered by the generator and the types of appliances used are two major factors that can affect the runtime. A small fridge (around 200 watts) may let the generator run 10-12 hours, but a space heater (around 1,500 watts) might last just two to four hours.
In the end, figuring out how long various battery powered generator will last for various needs is crucial. To learn more about good choices see: battery operated generator
