I support around 300 Macs for work. In my extensive experience, the deal here is that people are FAR too rough and careless in winding up those charger cables over and over. Apple HAS implemented strain relief here and done their best to make the points of failure less vulnerable. Here's a tip:

Instead of yanking the cable at a 90-degree angle and winding as tightly as possible, let the cable come out of the charger naturally, perpendicular to the charger, make a small loop, and then wind the rest of the cable gently around the two plastic hooks that are provided. If you do this, the charger will last a LOT longer.

The simple fact is that there is no way to make a wire that gets twisted and yanked and bent at a 90-degree angle, and which will nevertheless last forever. That's just not a thing we can do.

Another tip is: own 2 of these chargers, one for home and one for walking around, so that you don't have to wrap up your only charger over and over, every day.

Re:Macbook charger teardown: surprising complexity inside Ap... by Alupis on Wednesday November 25, 2015 @04:31PM (#10629848)
Way back in my computer repair days, I used to commonly see macbooks with horrendously frayed and/or just generally poor condition chargers. While, other laptops didn't seem to have that issue nearly as often (although breaking the DC jack was a common problem for those folks, but that's a different issue).

You shouldn't have to be tender and gentle with the power cable for your device... it should be durable and stand up to abuse. After all, it's for a laptop which may experience hard yanks as people walk away with it plugged in, the cable being stepped on or crushed by a chair, being thrown into a bag not coiled (or sometimes coiled too tightly), dropped from waist-height (or higher), thrown to a friend, etc.

It's not unreasonable to expect these things to be very durable. Functionality and durability should take precedence over design aesthetics here.

(as an aside, the white color always ended up looking filthy in short while, and was nearly impossible to restore to bright white)

Any cable you have to wrap it the way it wants to go, any forcing of flexible wire will always cause damage. That is the nature of wire until we create an improved technology. This is not just computer cords, it is ALL cable, from power supply for concerts to the home depot cords (even the most expensive). You can manufacture to allow prolonged life, but expect a heavy/hard user who wants to not take care of the cable, and expects it just to just last will be the first to fail. If you believe otherwise, the cable business needs your help in creating the technology.

Great, so you explain how Apple's design is faulty, and how it could be improved. I think you'll find this is easier blustered about than done.

PC chargers, for instance, are universally worse. A lot worse.

This design already does the best job in the industry at handling hard yanks——that's what MagSafe is for. And it does fine with ordinary, expected use and abuse of the cable. And it does great with being thrown into a bag or dropped.

What it doesn't do, because that's impossible, is to magically become able to be yanked on 500 times and coiled as tightly as possible around itself, without ever wearing out. But I've offered a solution to that.

Your implied accusation that "design aesthetics" have taken precedence over functionality and durability is unfounded. The fact is that Apple's charger works a lot better and is a lot more durable than the competition.

> PC chargers, for instance, are universally worse. A lot worse.

This is an unsubstantiated claim not backed by any evidence. In fact, your original post speaks against your very claim - you advocate people be ginger with their chargers or risk breaking them.

> This design already does the best job in the industry at handling hard yanks——that's what MagSafe is for

You mean to say "that's what MagSafe was for". Magsafe is gone now... (although I would generally agree that type of connector is good).

> it does fine with ordinary, expected use and abuse of the cable

Clearly not the case, as evidenced by this thread here.

> And it does great with being thrown into a bag or dropped.

I can't speak to either way except with anecdotal evidence of having to replace far more macbook chargers than any other type.

> What it doesn't do, because that's impossible, is to magically become able to be yanked on 500 times and coiled as tightly as possible around itself, without ever wearing out

Somehow my Thinkpad's charger hasn't worn out, and I'm guilty of every laptop charger sin there is. The same holds true for my previous Dell laptop. These types of chargers are usually made from hard plastic, with a plastic cable. They don't fray the same way macbook rubber-y chargers do. In fact, Dell's chargers are designed specifically to be tightly wound around the charger and come with a nice rubber strap to hold it tight.

> Your implied accusation that "design aesthetics" have taken precedence over functionality and durability is unfounded

Perhaps, but it does seem so given all the anecdotal evidence in this thread. It looks pretty, but wore out far quicker than most should.

> The fact is that Apple's charger works a lot better and is a lot more durable than the competition.

This is another unsubstantiated claim, and/or is supported only by your proposition people treat their chargers with tenderness (which isn't going to happen).

Plain and simple - these things need to be designed to take a lot of abuse. If Apple can do that, great... but it seems they took a giant leap backwards with the new USB-C charger which will cause the infamous "broken DC jack" problem all over again.

It's not gone, it's present in all most selling Mac laptops, my latest rMBP has it, I think they only removed it from new MacBook because it's too lightweight and the magnet need to be super weak in order to get itself ejected once it's pulled without pulling the laptop itself, and usb type c was probably used to eliminate excessive separate chargin port to make this particular laptop lighter and smaller which is its main purpose.

Alupis: I should have clarified that I was speaking from my own personal experience with supporting hundreds of laptops. You're right. I admit that my evidence is anecdotal, but there is a lot of it.

As others have already pointed out, no, MagSafe is not gone.

Dell's chargers, as do many other PC chargers over the last 10 years, routinely break the charging port on the computer if they get yanked on too much, which is of course far more expensive to replace than a new charger.

You're bitching a lot about my evidence being anecdotal because it's only based on hundreds of chargers, and you're right, but your evidence appears to be based on, um, a single Dell charger that you think is awesome. That seems pretty weak.

Lastly, I do agree with you about the new USB-C charger for the MacBook. I think it's stupid and a step backwards and I wish they had retained MagSafe on that model.

> from my own personal experience with supporting hundreds of laptops

I'm curious to how much hardware support goes into this, since most Apple machines are designed to not be support friendly (eg. non-replaceable and/or difficult to replace normal wear-n-tear components).

> routinely break the charging port on the computer if they get yanked on too much

Yes, most laptops have this issue, although it's not nearly as common with modern laptops as it used to be. However, I contest that's a design fault in the laptop, not the charger.

> which is of course far more expensive to replace than a new charger

Not always true.[1][2] DC jacks can often be bought for less than $5 online, and then it's just labor to solder it into place. A search online turns out quite a few services for $75 inclusive of the DC jack cost (your local repair shop probably does it even cheaper now, since no shipping involved, etc). Apple's cheapest adapter with magsafe cable on it is $79. A Thinkpad charger will only run you $59.99.[3]

> You're bitching a lot about my evidence being anecdotal because it's only based on hundreds of chargers, and you're right, but your evidence appears to be based on, um, a single Dell charger that you think is awesome. That seems pretty weak.

It's difficult to comment on this without resorting to some sort of "fanboy" argument.

> I think it's stupid and a step backwards and I wish they had retained MagSafe on that model.

I think we both agree on this. Worse off, if that single port breaks, you now cannot charge your laptop, nor use any peripherals (and a peripheral is more likely to break that USB port than the charger in my experience - such as a USB thumb drive hanging out and someone smacks it on accident). Even worse off, that port isn't easily repairable, so it's back to apple (who will replace the entire motherboard as their "fix", or if it's out of warranty, it's time to buy a new laptop).

That USB-C port looks very sturdy. See, the connector case is milled into the macbook body. And the connector itself is a separate module that can be replaced with just a right screwdriver.

The issue isn't the entire port breaking, it's the relatively fragile plastic center part inside the port that breaks most often. Breaking that renders the port unusable.

It's not fair to compare 3rd party repair services to a new Apple product. There are also 3rd party repair services for Apple chargers. For example, I know these guys will repair them: http://madmacsoforegon.com/Mad_Macs_of_Oregon/Welcome.html

Absolutely not.

I use a MacBook Pro, with the MagSafe feature hard, right along with a Lenovo higher end laptop. They both travel, they both get the same treatment.

I have gone through several Apple chargers. I have had exactly ONE Lenovo charger. The same was true for my older T60P and it's charger. In fact, that one is still like new, despite 10 years of use.

I like the MagSafe, and it has prevented a few strong yanks, or trips over the cord from damaging the Mac, but it's also prone to failure in the wire near the MagSafe connector, just as it's prone to failure in the wire near the charger assembly.

Interestingly, the Lenovo chargers ship with a nice Velcro wire retainer that is intended to be used right after WRAPPING THE WIRE FIRMLY around the charger. And the Lenovo devices have both easily gone a couple thousand use cycles, the older one maybe a couple more.

There really isn't a single metric, other than size, that favors the Apple charger in my use case.

I'm typing this on an Thinkpad X60 which is plugged into a power supply of similar vintage to the machine judging by the IBM branding &c. The laptop was manufactured in December 2006 and is ex-corporate (i.e. not treated with kid gloves) and judging by the nicks in the cable, the PSU has had a similar life.

So might Apple PSUs for all I know, my ancient white iBook G4 psu is still serviceable although the iBook is in its box because the hard drive sounds like a food mixer and I can't be bothered to go through the procedure needed to remove or replace the drive...

It's rather unfortunate that most Apple computers (with non-soldered hdd's) still require this level of complexity to change out a routine maintenance component that's expected to fail. (or with some models, the hard drive cannot be replaced at all).

> Apple HAS implemented strain relief here

That's not the same as implementing good strain relief. I used to work for a company that made medical devices. One of our products started with a cable with strain relief, and it kept breaking (a wearable monitor). We 'implemented better strain relief', and it kept breaking. It was revision D where we got it right and the cables stopped breaking. And if cables can't survive a 90-degree bend, then stop them from being able to be bent that far in the first place (we had to).

And to be fair, other companies don't have this problem, because they engineer their chargers for how people will use them - basically what you're describing is another form of "you're holding it wrong".

Re:Macbook charger teardown: surprising complexity inside Ap... by Bud on Wednesday November 25, 2015 @04:47PM (#10629948)

Anecdotally, neither the 7-or-8-year-old charger for my Toughbook nor the four-ish-year-old charger for the treats-all-her-cabling-like-it's-meant-to-be-load-bearing roommate's Toshiba Satellite have failed.

Apple definitely seems to be an outlier in this arena and is well known for their not-infrequent decision to sacrifice function, user comfort, and/or safety for aesthetic appeal.

I've owned Macbooks consistently for about 6 years now, I always use that little loop technique when winding the cord. I've never had a charger fray or fail on me.
Re:Macbook charger teardown: surprising complexity inside Ap... by DanBC on Wednesday November 25, 2015 @03:29PM (#10629464)
I use the loop technique. I've had two cords self-destroy.

I'd need some persuading that the rubbery sleeving was chosen for purely engineering reasons, and not mostly "it feels nice".

Re:Macbook charger teardown: surprising complexity inside Ap... by knowaveragejoe on Wednesday November 25, 2015 @05:20PM (#10630137)

As a counter anecdote, I am _very_ careful with my charger (and cords in general). The only chargers I've ever had fail are from Apple. I finally got tired of it and bought a counterfeit charger that wasn't as "clever" (i.e. didn't have a thin gauge coaxial cord with a weak rubber insulation), which has lasted far longer.
Re:Macbook charger teardown: surprising complexity inside Ap... by engi_nerd on Wednesday November 25, 2015 @04:56PM (#10630012)
This seems to be very much a "your mileage may vary" thing. I always used that same technique and went through 4 chargers before I finally got sick of the darn things. Then there are a lot of people like you who think that people like me must have hammers or wire dikes for hands.
Re:Macbook charger teardown: surprising complexity inside Ap... by ksk on Wednesday November 25, 2015 @07:12PM (#10630624)
I think a charger should be much more robust than this. Other laptop manufacturers have already figured out how to avoid such a simple thing. I can only speak from my own experience, and after one MB Pro and two iPhone chargers with frayed wires, I'll take my ugly Sony Vaio charger over a 'brilliantly' designed Apple one any day of the week.

If using a product in the most obvious and intuitive way causes it to fail, it's the product's fault, not the user's. It should be redesigned so the obvious use is the correct one. Plenty of laptop power supplies have cables designed to wrap around the brick for storage and don't have failure rates like this.

Apple has not implemented proper strain relief, with a perforated sleeve (presumably for aesthetic reasons), and they still use a thin, over-flexible wire. Their own website shows the cable wrapped tightly--on a page about avoiding cable damage, no less. (https://support.apple.com/en-us/HT201600)

Blaming the user for, essentially, not being an engineer is common in the tech industry, and it really doesn't help anything, especially from a company that claims to be (and generally is!) as user-friendly as Apple.

> Apple HAS implemented strain relief

Apple favors form over function and tries to make their cables in interfaces as small as possible. The result is that there's no room left in their designs for adequate strain relief. They end up using the smallest cables they can get away with and have a bushing around the cable as it enters it's housing to protect against lateral force and that's about it. There's rarely any internal strain relief mechanism.

Re:Macbook charger teardown: surprising complexity inside Ap... by ghaff on Wednesday November 25, 2015 @06:43PM (#10630523)
The odd thing is that the cable going to the laptop is probably too thin/not stress-relived enough (I've "only" had one fail but it seems a marginal design). However, at the same time, the alternate plug with the extension length of cord attached practically looks and weighs like something I'd attach to a mainframe. I don't travel with it for that reason. It's always seemed to me as if the two different components were designed by engineers who didn't even talk to each other--and it's been that way for years.

There may be a UL thing going on at the 120/240V side of the charger but it still seems ridiculously overengineered.

I can't agree with that. Someone at Apple fetishizes thin cables to a dangerous degree.

These power supplies aren't as obviously defective by design as an iPhone cable, but after looking at the amount of design detail and engineering directed at the power supply and MagSafe, the sacrifices made seem pretty insane.

Re:Macbook charger teardown: surprising complexity inside Ap... by oaktowner on Wednesday November 25, 2015 @06:59PM (#10630570)
I couldn't disagree more. Chargers should be durable enough to handle typical usage.

People aren't "FAR too rough and careless." People behave as people behave.

A high end manufacturer like Apple should be design and manufacture their devices to stand up to the rigors that people typically put them through.

Why doesn't Apple? Because their user base (or at least the majority of their user base who winds chargers too tightly, which I apparently fall into) would rather buy a new charger every year or so than switch computers.

It's quite profitable for them.

[Edit -- fixed typo]

Re:Macbook charger teardown: surprising complexity inside Ap... by GigabyteCoin on Wednesday November 25, 2015 @06:00PM (#10630349)
The problem is that apple expects typical consumers to treat the cable with such care.

Why should I have to buy 2 chargers (at $99 a pop, no less) when one charger for pretty much every other laptop company out there will work for years with "rough and careless" users, and only cost $20 to replace?

You can also ignore the foldable hooks on the charger entirely, and wind both the low voltage cable and the power cord (if you have it attached) together in a comfortably-sized coil. This way the low voltage side doesn't have to take any sharp turns (and the other end with the power cord seems to have a stronger strain relief, which should be able to handle a light bend).

Yep. And Apple did. That's why there is more robust strain relief than it used to have, and that's why there is MagSafe, which is vastly superior to the PC side when dealing with yanks and ordinary abuse.
Re:Macbook charger teardown: surprising complexity inside Ap... by specialist on Wednesday November 25, 2015 @05:17PM (#10630123)
I much prefer the disposal (consumable) MagSafe adapters. I've ripped out the prior RCA (?) style Powerbook connector numerous times.

But if the MagSafe connector cannot be made more robust (durable), then it should be replaceable.

If you can, count how many strands are inside that wire. If it's fewer than 90 strands you know why this wire fails.

I bet it's probably only 19 which is the minimum for a moving wire not to break.

> That's just not a thing we can do.

Yes it is. Assembly robots that move all day can have even 5,000 strands in the wires in a careful helical winding pattern that prevents the strands from being under tension - those will not break even after constant movement and folding.

Dell makes chargers that are very small (or at least thin) but are very though. The Apple charger is small but quite bulky (especially with a UK plug) I got both an MBP 15 and a Dell XPS 15 and the Dell charger fits better in every bag i have. It's has the overall footprint of a ~5-5.5" phone/phablet and is about half as thick as the Apple charger. http://www.amazon.com/Original-Dell-Replacement-Precision-Co...

I actually find the Apple charger a bit annoying, it doesn't fit flat in any of the smaller / side pockets of my briefcases or messenger bags, and overall the Dell charger isn't "ugly" if you would gave it the apple "storm trooper white" finish and an apple logo it would not look out of place in Apple's catalog.

The other thing I kinda hate about Apple is the fact that it won't take a standard mickey mouse cable, if you forget the cable / socket plug you are pretty much screwed if you are at a non-startup company :<

I go through about one of these chargers a year. I leave one at my desk at home, so I don't have to move it, and I take the other one with me on the road. The one I travel with gets plugged and unplugged probably 5 times a day... and it never lasts more than 6-8 months. Shitty design.

Nope. This has happened to just about every Apple cable I've ever owned. MacBook Pro power adapters. MacBook Retina power adapters. iPod cables. Lightning cables. The insulation gets frayed. Sometimes there have been sparks. This has never happened to any USB cable I've owned.

It's almost as if they make a profit off of selling licensed cables with their proprietary technology or something.

How about producing a charger with more robust wiring? The power brick for my Thinkpad X200 is now more than 6 years old. It has been treated very roughly, but has thicker wires, robust strain relief, and has never failed. In the same amount of time, I've gone through three Apple chargers. It's a little silly.

> "people are FAR too"

I'll stop you right there, No.

Men should not serve machines. Machines should serve men.

If the machine cannot take the abuse that people typically subject it to, then the design of the machine needs to be revised. Trying to modify human behaviour to suit the unnecessary mechanical limitations of machines is insane.

Good tips ! I do exactly this and have a charger that has lasted 5 years. Cable looks good still (touch wood !)

You know what I think? It’s not our carelessness but the plastic they use for the cables: I own 2 chargers for my MacBook. I do the loop for the charger I carry around. The one I leave home on the floor never got wound up. It looks like this after about two years: https://twitter.com/Udo/status/667295383299579905

Your tip is great, but I do this.

I have a charger in a cable tray under my desk. Above my desk, one of these guys: http://www.amazon.com/gp/product/B004GUS4XK

I've still had two Macbook cables fray, the sheath opening up like a paper lantern. There is near zero strain on this cable at any point.

Sorry, but I am really bad at following written instruction like origami... without visual instructions.. Is https://www.youtube.com/watch?v=FWRcszmX_p0 what you tried to demonstrate?

I have a charger I only use at home and it's hopelessly frayed. The users are not the problem here.
Re:Macbook charger teardown: surprising complexity inside Ap... by bigiain on Wednesday November 25, 2015 @05:23PM (#10630153)
An alternative datapoint - I have a charger that's not yet frayed, but it is starting to get intermittent - sometimes I need to wriggle the wires where they go into the mag safe connector.

That's the original charger for my 2006 black MacBook. It was in daily use by me for work until I got my mid 2010 MacBook Pro, and was then used as a "home machine" by someone else up until early this year.

The charger from the 2010 Macbook Pro is still working fine (but I'll point out I left that charger at work almost all the time, and "borrowed" the 2006 one when I needed to top up at home).

I suspect a difference is that I never "wrap the cable round the hooks", I just loop the cable up loosely and drop it all in my bag. I do the same with my iPod/iPhone cabes, and I've only ever had one of those fray (and I suspect that was one that got borrowed a lot). I wonder if this is a "you're holding it wrong" design oversight, where they've had lots of people using and testing them, but all in very similar ways which are not the only way they're used outside Apple?

Re:Macbook charger teardown: surprising complexity inside Ap... by metafunctor on Thursday November 26, 2015 @01:05AM (#10631530)
Yep, I think this is it. I also have 5 years old MBP with the original charger, and it's still fine. I'm not a very careful person, and in general never wrap cables in loops, just cram them in the bag. Sometimes my cables get impressively tangled, but I think I'm still actually saving time by skipping the meticulous wrapping every time I take off (at least twice per day).

So maybe if you stop taking "good care" of your charger, and stop wrapping it in a tight loop, it will actually last longer.

That said, a lot of people seem think you're supposed to wrap the cables. After all, the MBP charger has built-in hooks for exactly that purpose. The charger is badly designed if wrapping the cable around the provided hooks causes it fray very quickly.

If they did usability testing, then the first thing they probably did was train the sample users. It's possible that fixed the test so that they never see the use case we're describing.
Re:Macbook charger teardown: surprising complexity inside Ap... by bigiain on Thursday November 26, 2015 @04:19PM (#10634785)
Probably not even "fixed the test", it might be something as innocuous as "Steve always walked around with the cables just looped up, not wrapped around the hooks", so that's what everybody else in the "sample users" group did too.

I'm on the third charger for my 2011 Macbook Pro. One of the broken ones has a slightly frayed cord which I repaired with tape, and I don't think it's the wire that broke it (though I admit I can't be sure). The other one has a completely undamaged wire, and yet also stopped working.

I really think it's the internals that are too fragile.

Re:Macbook charger teardown: surprising complexity inside Ap... by revelation on Wednesday November 25, 2015 @05:28PM (#10630175)
Yes, so that's why we invented plugs. That's a thing we can do.
Re:Macbook charger teardown: surprising complexity inside Ap... by eru on Wednesday November 25, 2015 @10:12PM (#10631054)
I wonder why they didn't go for a design, where doing the natural winding would not cause a 90 degree bend. (Eg they could let the cable come out of the charger at a different angle.)
Re:Macbook charger teardown: surprising complexity inside Ap... by fit2rule on Thursday November 26, 2015 @09:09AM (#10633012)
My tip for trouble-free cable management: Never wind the cable. Always fold it. Always. Whether its a rope, a cable, whatever: every time you wind it, you twist the fibers.

Instead, grab both ends, hold them together, untangle and pull the two sides together .. find the new ends, combine them, fold, over and over .. until you get a nice tidy package.

This treats the cable much nicer - its built for expanding in the combined loops, but when you wind .. and wind .. and wind .. you twist the fibers. Fold, don't twist!

I am a charger hoarder: One at work, one in the backpack, several at home.

Take my phone for example - I tend to have a charger in every room of the house, several for my backpack and one at my desk.

Re:Macbook charger teardown: surprising complexity inside Ap... by lostgame on Wednesday November 25, 2015 @06:50PM (#10630547)
This wouldn't be an issue if Apple's chargers weren't so proprietary to the point where third-party developers can't even manufacture their own devices.

I wonder if they'll allow non-Apple USB-C chargers. I think they'd have to.

I've always used the loop method with chargers and adapters, because of my decades as a musician dealing with various kinds of cables. When cables fail, it's invariably at one of the two ends where the cable gets bent and twisted. In fact, a bad cable can almost always be repaired by cutting off a couple inches from each end and re-attaching the plugs. Strain reliefs of various types help prolong the life of a cable, but not really by very much.

A quality product simply wouldn't have that problem. Quality means it can take some abuse, and you see it all the time in tools for many professions.
Re:Macbook charger teardown: surprising complexity inside Ap... by bad_user on Thursday November 26, 2015 @01:28AM (#10631593)
You're wrapping it wrong.
Re:Macbook charger teardown: surprising complexity inside Ap... by greggman on Thursday November 26, 2015 @04:16AM (#10632073)
That's not my experience. I don't yank my power cable and after replacing 2 of them I now wrap up the cable leaving a 4 inch loop of cable coming out of the adapter. So there's no 90 degree twist where the wire comes out of the adapter.

Unfortunately there's still often a 90 degree turn where it connects to my MBP. I've found no reliable way to prevent that.

If people in general are not careful enough with the product, it sounds to me as the product is not built well enough for regular use.
Re:Macbook charger teardown: surprising complexity inside Ap... by mcv on Friday November 27, 2015 @04:11AM (#10636552)
It's not just an issue with Macbook chargers; my wife's iPhone and iPhad chargers are in far worse condition. They keep falling apart in new and creative ways that my micro-USB chargers don't.

Re:Macbook charger teardown: surprising complexity inside Ap... by grandalf on Wednesday November 25, 2015 @03:47PM (#10629584)
I do these things and have only had one failure in the past 5 years (and it happened while someone was borrowing the charger from me).
Re:Macbook charger teardown: surprising complexity inside Ap... by ricardobeat on Wednesday November 25, 2015 @03:39PM (#10629532)
It also frails at the MagSafe end, where gravity naturally twists it. I had this happen to mine (after 5 years).

Strain relief is not a discrete binary variable, but a continuous one.
