Mobile phone batteries and electric meters are power equipment that we often come into contact with in our daily life. Understanding their working principles and characteristics can not only help us to use them better, but also help us to save power resources better.

The energy of the cell phone battery.

The mAh on the mobile phone battery represents the "energy" of the battery. For example, a 700mah battery is equivalent to an energy warehouse, which stores the vitality of mobile phones. If the mobile phone only consumes 70ma per hour, then your mobile phone can spend 10 hours with you, full of vitality!

The electricity bill on the electricity meter

The kilowatt-hour on the electricity meter is the "electricity bill" at home. If the total power of home appliances is as high as 5000W, it will take 5 kWh to work 1 hour, which is often called 5 kWh!

The pronoun of voltage

Volt is synonymous with voltage. A battery is like a reservoir. Volt is the height of the reservoir, representing the "charge" of the battery when it is fully charged. For example, the rated voltage of 700mah battery is 5V. When the power is reduced, the voltage is also reduced. If it drops below 5V, it's time to "charge" it! Remember, it is best to keep the voltage of 5V when charging!

A little knowledge of power

Knowing these little knowledge of power consumption can not only make your mobile phone battery life longer, but also help you save more electricity!
