In the previous unboxing and test video of the iPhone 14 series,
we found that the MFi chip of the included USB-C to Lightning cable has been changed from C94 to C91M.
So, today we gonna take apart this cable and check its internal structure.
The cable is fixed with paper clips.
And it continues Apple design, white and simple.
The junction is protected by an additional protective sleeve.
The USB-C connector is not full-pin design.
And some info are printed on the cable.
Model is A2561.
The cable length is about 1.04m (3' 4.94'').
And the diameter is 3.07mm (0.12 inches).
The weight is only about 20g (0.71 oz).
As we mentioned, the ChargerLAB POWER-Z MF001 shows it's a 100% original cable.
The MFi chip is C91M.
And the manufacturer is Foxconn.
Then, let's go ahead and use the cutting machine to take it apart.
Let's start with Lightning connector.
Use the spudger to remove the plastic case.
The internal PCB is wrapped with metal shields and fixed by spot welding.
The cable tie fastens the cable tightly and is used for grounding and shielding.
Remove two pieces of steel covers.
We can see the internal PCB.
All wires are reinforced by injection molding, which is the amber part.
There's a big chip on the small PCB, which is the C91M.
Model is AS3616A.
It integrates PD protocol identification, encryption module, and product info.
Flip to the back.
The solder joints are protected and fixed by glue.
A chip with CSP package is under the glue.
Next, let's continue to take apart the USB-C connector.
Use the spudger to remove the plastic case.
And the metal shields are pretty similar to the Lightning connector.
Except for removing the metal shields, we also removed the
metal cover that protects the pins this time.
So, you can clearly see the entire connector.
The connector is also reinforced by injection molding, which is the amber part.
And it didn't adopt full-pin design.
The pins on both sides are slightly longer than the others and are used for grounding.
It's a proprietary design of Apple.
The negative, positive wires, and other wires are soldered on one side.
And two filter capacitors are soldered on the back.
The internal pins are plated with gold, which makes them anti-oxidant and more durable.
Finally, cut off the cable.
There're five different wires inside.
And let's remove the TPE.
There's a layer of shielding net.
And a layer of aluminum foil for shielding is under it.
All five wires are wrapped in aluminum foil.
The twisted structure can eliminate stress and make it more flexible.
Those two red wires are used for positive power supply.
And the white wire is D- wire, while the green wire is D+ wire.
They're used for USB2.0 data transmission.
The blue wire is CC wire.
Those four tinned copper wires are negative wires and connected in parallel.
There're some additional tension fibers inside the cable.
Well, that's two connectors and all wires of this cable.
Since Apple removed the charger, that's the only accessory inside the box.
And its model is A2561.
We found the big MFi chip, C91M, is soldered on the lightning connector.
Its overall quality also continues Apple's consistently high standards,
with good protection and shielding performance.
OK. That's all for today's video.
