When charging your phone, should you plug in the cable first or the charger first?

Plugging in the phone charger is something that most of us have to do every day when using our phones. But have you ever wondered when charging your phone should you plug in the charger first or plug in the cable first, and after charging, which end do you unplug first? We invite you to learn in the article below to know how to properly charge your phone.

To get the answer, we will first learn about Surge – current surge or electric shock. This is a condition where the voltage is too high to instantaneously exceed the normal working voltage, which can produce a rapid and intense pulse of about 1 millionth of a second.

For example, a phone charger has an output voltage of 5V/2A, when plugged in instead of the output voltage of 5V, it can spike to 6V or higher, so there may be a surge, which we visible to the naked eye sparks of electricity.

For ease of use, this phenomenon is similar to when opening a faucet, water will spurt out at first, then run steadily.

Surge is rare but can still cause your phone a number of problems such as interference, circuit failure, data loss, performance degradation, shortening of battery life, phone crashes and reboots. , screen flickering…

With good chargers, with overload and surge protection circuits, you will not have to worry about this problem and can rest assured that you can plug in the charger first or plug in the cable first.

But with 3rd party chargers, chargers are not included with the device, to avoid surge users should plug in the charger first, then plug the cable into the device when charging. When fully charged, users should unplug the cable before unplugging the charger from the power source.
