What should be paid attention to when using non-original mobile phone charger

When the mobile phone is charging, the mobile phone itself determines the charging current, so when charging, the mobile phone generally automatically detects the load capacity of the phone charger, and determines the current input amount according to its own power. But I have to say that there are some charging problems that still need attention.

1. When using a high-power charger to charge a low-power mobile phone, is it harmful to the mobile phone? The harm is small because the mobile phone has a current adaptive function. Therefore, when the mobile phone is in the charging mode of 5V/2A, if the charger is charged by the 9V/2A charger, the charger will automatically recognize the charging specification of 5V/2A. Another example is the high-powered iPad charger that can charge a small-powered iPhone, and it will also be based on the iPhone’s current standard.

2, low-power charger to charge high-power mobile phone, is it harmful to the mobile phone? Have the agreement does not hurt the machine, such as iPhone8 support fast charge, but configure the 5V / 1A charger agreement, this will not affect. If there is no protocol charger, it is working at full speed, causing the phone to heat up and hurting the charger. So usually, don’t charge a 5V/2A and higher power phone with a 5V/1A charger.

3, fast charge charger to charge non-fast charge mobile phone, will hurt the phone? At present, some fast charge chargers on the market, in addition to fast charge power, will retain 5V/2A standard charging power, such as Huawei’s P10, Samsung S8 and other mobile phones. This setting is mainly to prevent us from using the fast charge charger on a mobile phone that does not have a fast charge function, resulting in accidental damage to the mobile phone.

4. How to choose a third-party brand charger? The compatibility of third-party brands is good. However, the charger with the highest matching degree can be purchased. For example, if the mobile phone supports QC3.0 or Huawei’s FCP fast charging protocol, then you can select the third-party brand charger of QC3.0 and FCP protocol.
