wow I also did not expect that amount of circuits, just my assumption: it is also needed for the new Antispark detection which is needed for USB PD EPR. Because with 28V if you suddenly unplugs the cable, there could be sparks which are burning the contacts
I've been looking forward to this video for a while! I was expecting some complexity but didn't expect to see so much active circuitry at both ends of the cable.
Out of curiosity, since someone brought it up regarding the charger itself having more RAM than the first apollo mission: 🤔 How much RAM and ROM do you think the chip in the USB-C end and the Mag-Safe end of this cable have? Tried to google for the chips from your video images but didn’t have much luck. Thank you! Greetings from Berlin
I read somewhere that it was somehting like 32kb. Apollo had something like 2kb of erasable memory, and 32kb of Rom. Tho note that these are both magnetic core memory.
I wish that future Macbook Pro 16 inches could use USB C 140 charging, with a compatible 140w (28v 5a) USB C Charger, and a 48V 5A (240W) rated USB C cable (which they exist now thanks UGreen)
Could you please give a suggestion for magsafe 2 to USB C cable or adapter? Searched everywhere on google, no clear answer and lot of people are looking for a solution. Some of the cables work but only intermittently. Thank you in advance
Blimey. I felt queasy when you started cutting into a £49 cable! But it's useful to know what goes into a cable like this. It goes some (ok, a little) way to explain the extortionate price tag. Thanks!
@ChargerLAB do you know if the 1-Wire protocol is used in the Magsafe 3 connector (as it was in Magsafe 1/2) for reading charger data and controlling the LED in the Magsafe plug?
Hi, hopefully you can see my message. My dog has bitten the cable into pieces and I would like to seek your advice whether the cable is repairable and should I solder all 10 wires or only the 5 thick wires to restore the charging function.
Please make a video on Apple type-c to c cable.. I also want to know how much watt it can support if I want to charge my macbook pro with that and is it a 5Amp cable. Thankyou.
Man, I was hoping I could take a MagSafe 3 cable, take the USB-C end, cut it and solder it to the inside of an Apple 27" Thunderbolt Display for power. I just got a 16" MBP M1 Pro, and i'm using a MagSafe 1/2 to USB-C adapter. It works fine, but only provides 45 watts of charging power, do definitely no fast charging. The MBP sips power so it's fine as is, but it does take up one of the USB-C/Thunderbolt ports, I'd much rather use MagSafe, even if the Thunderbolt Display can only provide 85 watts, which is better than 45 watts on my current solution.
@@jimtran93 yep, this is pal legacy But some cameras can work in both modes or can switch 50/60 modes in lower resolution (Like 4k only 25/50fps, but can 60hz in FullHD) I just ask about 60fps if you have technical possibility for this (really it doesn't matter for some disassembly video, even 30fps is fine)
Says 1080p50fps but the video looks like it was rendered at a lower frame rate. Edit: so some of the clips are 50fps, some are not. I hate that it’s not consistent.
The cable which comes with ipad pro(M1/M2) have no model information on it. A serial number is present but shows invalid on apple's site. No model nuuber is present. I was able to check that it can provide 65W to my macbook pro 14 with Samsung 65W trio charger, but I don't have any higher wattage charger to check further. Can you guys do a teardown of that cable?? Thankyou in advance
Nice ! Hope the cable is more durable than previous generations!! My last one work not well, it cause charging problems with power adapter. I then had to buy a new Ubs C-C type cable + new adapter. Apple just just do warranty on laptop mainly, they not really care about warranty of charger and cable even I bought Apple care . 😒 unfair for me !!
Am I correct in thinking that the 3rd prong of the plug that plugs into the wall (the earth plug), connects to the metal shield through the cable, and then to the MBP body? I keep hearing that if you have only a 2 prong plug, then a voltage flows through the body, which can be felt as a strong tingle in your hands, but if you have a 3 prong plug, this is gone? If so, can someone explain why the hell the body even needs to be earthed? Why is the charge even flowing through the body in the first place? Is it due to the track pad?
My cable has got very dirty(expected as it was silver/white ) and has ink stains on it. Can I wash it with soap water? Pls guys help me out . Much appreciated.
Apple is doing a great job always! But a moment to appreciate this channel and people putting so much effort to do all this reverse engineering, Well done great job!! 👍👍❤️
My guess is the single GND wire is to prevent potential ground loops and have a single common ground path. For the 4 positive wires, it looks like the MagSafe connector has 2 pins for V+, and it looks like the two pairs of positive wires comes in a twisted pair for EMI rejection- so it might make sense to have a single twisted pair of cables per V+ connection, so 4 wires total. I haven't done any electrical engineering work in a while so this is just my armchair speculation.
The two large shields that are wound around the outside of the inner conductors will be grounded at both ends as well, and so will act as additional "0V" conductors. Given those shields seem to contain many more strands than the inner red conductors, I'd imagine the positive and negative conductors are fairly well balanced (as you would expect it to be).
@@choilive You don't get any EMI rejection from a twisted pair of cables that aren't differential, so you'd need to have a twisted V+ and V- pair for there to be any EMI rejection benefits. Given all of the ground conductors would be grounded to a single node at either end, there isn't any potential for a ground loop due to having multiple ground conductors in the cable. A ground loop occurs when you have ground conductors terminated at different ground potentials, which can cause small current loops to flow. Because they're all connected to the same ground potential, there isn't any possibility for any loop current to flow.
Why does apple have to always be so difficult. What do they not get about rules that all companies must go to a common charger port which would be type c. 🤦♂️

I got nothing, nothing you hear..!!...why are you doing that to me... it hurts.. stop it.. mehh newermind..though there is a pigeon that sometimes sits in a tree not far from my window...

love how apple always uses fancy black substrate even in the least expected places.
wow I also did not expect that amount of circuits, just my assumption: it is also needed for the new Antispark detection which is needed for USB PD EPR. Because with 28V if you suddenly unplugs the cable, there could be sparks which are burning the contacts
Obviously no because default voltage is 5v if connected to the MacBook the charger and device negotiate to 28v with special pd protocol
I've been looking forward to this video for a while! I was expecting some complexity but didn't expect to see so much active circuitry at both ends of the cable.
my jaw litterly dropped when you cut the cable in half... lol i wasnt expecting that
Didn't know cables can be this complex... Good work bro...👍🏻
Lol....
Thanks for the most informative description and real tear down
Charging cables are so complex? Wow. This channel never ceases to surprise me.

Will magsafe 3 will work with magsafe 2 MacBook Air 2017 laptop??
It won't.

Edit: so some of the clips are 50fps, some are not. I hate that it’s not consistent.
My magsafe 3 cable got separated from the middle. Is there any way I can make it work again
Anyone got more info on the communication with the laptop? Doesn't seem to be using the same OneWire protocol as MagSafe 2.
Will TPE layer protect inside cords from water if spilled on cord?
Yes. But we strongly recommend you not to do this on purpose.

It didn't. MagSafe 3 is not compatible with MagSafe 2. We'll have a video to explain this.

What will happen if we try to charge macbook from oneof its own usc ports ?
Connecting magsafe and same usb c output of laptop with same cable!
You can already connect multiple chargers to the older MacBook Pro via USB C. It chooses the highest power input. I expect this one will be the same.

Is regular Apple USB-C to USB-C cable capable of 140W with this new charger?
only up to 100W, if you want more than 100W you need special certified USB C cables (Extented Power Range)
@@benwilliam1010 do the usb-c ports on the macbook pro support these higher wattages?
@@madamerosario good question, I don't know
LTT mentioned they don't. you can fast-charge, but not "ultra"-fast-charge

20W is enough for phone, but definitely not enough for laptop.
apple lied about fabric cable, there is tp layer inside
Isn’t USB-C 24 pins?

shield is pronounced "sheeld". wound in this context rhymes with "ground". The tear part of teardown in this context rhymes with "air".
So finally Apple also offers reinforced cables? Great! Four years too late! That unnecessary ancient Magsafe connector is insane and crazy.
