People in advanced countries do not know about the use of a domestic inverter but it is a useful gadget for the areas where power outage is common. Basically, the inverter converts DC to AC power and keeps your gadgets running uninterrupted. The run time of an inverter depends solely on storage capacity.

AS I have mentioned in my OP that the run time depends on storage capacity of battery. By the way there is a simple formula for how long a battery will last. The higher the Amp hour (Ah) of the battery longer it lasts. Then you have to keep in mind about how much wattage you're using.

Thanks for mentioning the Amp about the life of the battery. I know now that the life of the battery depends on the Amp (is this amperage?).

It's not the amperage that determines the life of the battery but it is all about calculation of how long your battery last if you use it to run your gadgets. The formula is

Power in Watts= current in Amperes multiplied by Voltage. I can give you more description about it if you're interested.
