How much power does a 5 volt power bank produce?
Usually a standard power bank output is 5 volt. In this case if we multiply volt x current i.e; 5 x 2.5 we will get total power 12.5 watt /hour. The desk fan as described is of 5 volt and 2.5 watt and should run upto 5 hours. Total calculation depends upon the battery condition and internal consumption of the power bank.
How long does the power of the fan last?
Long answer short, it will last for 2 hours. The fan has a motor, that consumes 5 Volts and 0.5 Amperes. This results in a total power consumption of 2.5 Watts.
What is the mAh rating of a power bank?
Usually the mAh-rating refers to the internal battery in the power bank. They are usually some kind of Li ion-battery with a nominal voltage of about 3.7V. Your fan draws 2.5W. So the power bank would last 9.25Wh/2.5W = 3.7h (3h 42m) in theory. There is a DC/DC-konverter in there making the battery voltage to 5V.
How many cells does a 2600 mAh power bank use?
A 2600 mAh power bank will use only 1 cell. Usually the mAh-rating refers to the internal battery in the power bank. They are usually some kind of Li ion-battery with a nominal voltage of about 3.7V. Your fan draws 2.5W. So the power bank would last 9.25Wh/2.5W = 3.7h (3h 42m) in theory.
