What do you need to know about mobile phone chargers?

1, What is the fast charging protocol?

Fast charging protocol refers to an agreement that the charger coordinates the voltage and current flowing to the mobile phone battery to reach the maximum power during the fast charging process. Like a faucet, it can control the flow of water. Common fast charging protocols include Qualcomm QC and PD protocols, as well as mobile phone manufacturers’ own private protocols.

2, What is a GaN charger?

The charger uses “gallium nitride” new material instead of “silicon”, which has the properties of high switching frequency, high electrical load and low on-resistance. Compared with ordinary chargers, the biggest advantage is its small size.

3, The difference between original charger and non-original charger

The original charger is the charger produced by the mobile phone manufacturer, and the quality, safety and after-sales are guaranteed. Non-original chargers refer to chargers other than original ones, which are not well recognized by mobile phone users.

Since mobile phone manufacturers canceled the gift of accessories, more and more people have begun to recognize non-original chargers. The original ones are too expensive, and the non-original prices are affordable. Now the charger technology is very mature, and the quality, safety and after-sale service of chargers made by some non-original manufacturers are also guaranteed.

4, Will the fast charging charger deplete the battery of the mobile phone?

No, the so-called wear and tear is the normal wear and tear of the mobile phone battery. We are currently using fast charging chargers, which have passed the national 3C, FCC, CE, ROHS certifications, and can be assured of safety. Common fast charging power is 20w to 120w.

5, Common charging head data line interface

Common types of interfaces include Type C, Type A, Lightning, and Micro USB. Type C interface has now become the mainstream electronic device interface in the market, such as Xiaomi, Huawei, oppo, vivo.

The Lightning interface is a unique charging interface for Apple devices, which is called MFI certification. Micro USB interface is the interface of old-style digital products, but it is slowly withdrawing from the market now.
