The question of the power consumption of mobile phone charging is both interesting and boring. Although many people may not care about the cost of charging a few cents, if I really ask you how much it costs to charge your phone, most people may not be able to answer. Today, the editor of Bus Digital, in the spirit of exploring unknown things and pursuing the source, calculated the power consumption of mobile phone charging clearly, so that everyone can be a clear consumer. Let's take a look at how much it costs to charge your phone together!

First, let's explain a few terms:

Milliampere:

Milliampere is the unit of measurement for current, represented by the letter mA. An is the internationally unified unit of current, represented by the letter A. It is also the current measuring point for the battery level of mobile phones.

Wh：

Wh is the amount of electricity, which is directly proportional to voltage, current, and time. And mAh is usually used as an indicator for battery charging and discharging, which is directly proportional to the charging (discharging) current and time of the battery. To make it comparable or convertible to Wh, it is also necessary to know the voltage of the battery.

3.7V lithium battery:

A 3.7V lithium battery is a type of lithium battery with a nominal voltage of 3.7V and a full charge voltage of 4.2V. Its capacity ranges from a few hundred to several thousand milliampere hours.

One kilowatt hour electricity:

One kilowatt hour of electricity is equivalent to one kilowatt hour, which is the amount of electricity consumed by a 1000 watt appliance for one hour of use. That is what we usually refer to as the amount of electricity in one word when buying electricity.

Power loss:

This needs to be determined based on the load at the end of the line, and calculating the loss of the line is a professional issue in electrical calculation. It needs to consider the internal resistance of the line, the temperature of the operating environment, heat dissipation conditions, the distance of the line, the cross-sectional area of the wire, the type of load at the end, whether it is an inductive load or a resistive load, and so on. Due to the negligible wear and tear of this part and the difficulty in calculating it completely, it is ignored here.

After reading the above content, we have a preliminary understanding of the units and losses of mobile phone charging. Now, let's take a 2000mAh, 3.7V battery as an example and use a formula to calculate how much power it needs to consume to fully charge it.

Calculation formula: [V] multiplied by [milliampere]=Wh power consumption

Example calculation: 3.7VX2000mA=7.4Wh (power consumption)

In this way, we have obtained the amount of electricity that this battery needs to fully charge without considering consumption -7.4Wh, which is converted into the amount of electricity we use in our daily lives, which is approximately 0.0074 kWh.
