Do You Know Whether To Plug In The Cell Phone Or The Power Supply First When The Cell Phone Is Charged?

The use of cell phones has now become a part of our life, and charging cell phones every day is also indispensable. So do you know the charging sequence of cell phones? Should the cell phone power cable be plugged into the cell phone first, or should the cell phone power cable be plugged into the power supply first? But don't underestimate the order of the two orders. Operational errors do great harm to the cellphone.

Before that, I will tell you the knowledge about surge. Surge is the instantaneous overvoltage beyond the normal operating voltage, also known as the transient pulse voltage. It is a kind of short current and voltage fluctuation that occurs in the circuit we usually use, and a kind of intense pulse lasting one millionth of a second will appear.

When we use electricity, we should notice that when it is charging, the socket sometimes emits sparks in an instant, or we hear the sound of "nourishing". These are basically surges that are making trouble, and the power surge is very destructive to the equipment.

So the question arises. In order to reduce the damage caused by the surge to the cell phone, should the cell phone be plugged in first or the power supply be plugged in first when charging?

If the cell phone is plugged in first and then the power supply is plugged in, a large voltage pulse may occur at the instant of power-on, and the excessive surge will pose a greater threat to the security of the cell phone.

If we plug in the power first and then the cell phone, although it is still unable to eliminate the surge, to a certain extent, it avoids the direct contact between the surge and the cell phone.

So to sum up, when we charge the cellphone, we should plug in the power first and then the cell phone. Warm Tip: With the above logic, when the cell phone is full of electricity, remember to unplug it first. Because at the moment of pulling out the charger, the charger is prone to produce reverse instantaneous induction current. If the cellphone is not pulled out first, it will probably damage the cell phone.
