Plug in the phone first or the charger first?
The answer is to plug in the charger first. When charging a mobile phone, the charger will convert the high voltage current into low voltage through a transformer, and then send it to the phone.
If you plug the phone into the charger and then plug it into the power outlet, there is a possibility that the phone will be directly connected to the power source, causing a sudden voltage surge. However, if you plug the charger into the power outlet first and then connect it to the phone, this situation is almost unlikely to happen, unless the power source is unstable.
It is best to plug the charger into the power outlet first and then connect it to the phone to avoid the risk of electric shock.
