This needs to talk about Apple's lightning interface. The new interface standard released by Apple along with the iPhone 5 replaces the old 30 pin interface. Those who used the early iPad and iPod nano products should be familiar with the 30 pin interface. I believe many families still have several such cables.

The essence of MFI authentication data line

 

 

MFI certification has strict requirements on the scale and number of personnel of the factory. Besides the high requirements for the material of data line, the data line certified by MFI is very important to the "authenticator" chip in the data line, which is used to ensure that it is the data line manufactured by Apple approved manufacturers.

 

This chip, about $2, needs to be purchased from apple. For this chip, apple IOS will do some synchronization. Once it detects that it is not its own chip, it will appear virtual electricity or pop-up windows and even cannot charge these phenomena.

There are two types of data wires for lightning interface, one is USB a flash switch port, the other is USB C port.

USB C port lightning data line

Now all the iPhone apple sells is randomly connected with USB C cable, without charging head. Some of the previous models are given randomly, and the one with charging head is USB a.

The purchase data line is recommended in several cases:

For iPhone 8 and later models, it is recommended that USB C port cable be used, because it can complete 50% charging in half an hour with 20W fast charging head, so-called fast charging effect can be achieved.

If you don't want to try fast charging, there is also a way to improve charging efficiency to 12W, using 12W charging head that supports apple 2.4a protocol) and USB a port cable.

To keep 5v1a, you can use the old charging head + USB a port cable.
