iPhoneX achieves fast charging, the key is data transmission!

Fast charging for the iPhone 8 iPhone/X, etc. with the support of the PD charger and the Type-C to Lightning cable.

Why can the Type-C to Lightning data line achieve fast charging?

Xiaobian bought a data line worth 188 yuan in the Apple Direct Store. Today I will take everyone to disassemble it.

â–¼

One Type-C and one Lightning, this structure was first used to charge on the iPad Pro. Lightning interface, gold-plated contacts.

â–¼

We cut the two ends and the cross section of the wire, we can see that the content is quite rich.

â–¼

The surface of the Lightning head is a plastic cover that is cut open to see a protective layer of the sleeve.

â–¼

You can see the stainless steel protective cover, which protects the inside of the chip circuit board.

â–¼

It seems that the workmanship is relatively good. The brass wraps around the end of the wire and is fixed by a steel ring. The solder joints are dense.

â–¼

We then remove the steel sleeve, both sides of the circuit board have chips, the surface has glue.

â–¼

The other side of the Lightning head is also chipped.

â–¼

We scraped the glue and found three chips.

â–¼

Type-C head, two rows of solder joints at the contact point, almost full soldering, looking more rigid.

â–¼

The Type-C head also has a row of stamped M74D F77LEF1. There is no chip at this head, two capacitors, and the other side is solder joints.

â–¼

Finally, let's take a look at how the wire itself is, with a layer of tin foil inside. The wire inside the tin foil is entangled and there is a strand of imitation. Two reds go positive, two CC lines, and five negative branches.

Overall, this data line is well-made, worthy of 188 yuan, can go high pressure, suitable for iPad Pro, iPhone 8 / X mobile phone high-voltage fast charge.
