Dangerous Apple Power Adapters? 240

An anonymous reader writes "Even with all these exploding Dell notebooks and other notebook safety problems, Apple has seemed relatively immune. Every once in a while, some odd thing came along, but it seemed like relatively calm waters. Not anymore — Apple's notebook power adapters appear to be the source of some serious safety concerns. Every iBook and PowerBook user should read this and keep a close eye on their adapter — the adapters suffer from very poor design including wires that seem prone to short out and burn and zero short circuit protection."

          Maybe a problem, likely not. Mac users tend to go nuts about manufacturing errors more so than others. Anyway, I got a macbook a couple weeks ago -- has the magsafe connector. I recall not too long ago tons of news about the magsafe burning up at the computer side. I noticed that when I pull the connector straight out from the computer, it stresses the joint where the wire and plug meet. Thing about a magnetic connection is that it is hard to pull the two sides straight apart, but easy to break if attacked from an angle. So now I just push on one side of the connector and it breaks away without difficulty or wire stress.

          I know everyone always claims to be gentle on their machines, but when I look at other people's laptops -- I suspect the truth is much rougher. Anyway, don't yank the adapter around by its cord and I bet it'll fine.

      Power adapters are low-tech, commodity devices. Since their profit margins are very low, Apple management probably subcontracted their design and assembly to a generic company in mainland China.

      One thing that we know about China is that (1) it has few laws ensuring product safety and (2) that Beijing rarely enforces those laws. As a result, many products from China are just dangerous.

      Consider the recent case of lead contamination of children's toys []. The toys had 5x the amount of lead that is considered safe.

      Now, consider the case of a bracelet that was 99% lead []. A Chinese company made the bracelets for Reebok. A child who accidentally ingested the bracelet died.

      Now, consider Chinese honey that is contaminated with a dangerous antibiotic [].

      Here is the summary reduction. The price of a product imported from China is $X. The price of a product made in the USA is $Y. Generally, $X is much less than $Y. The difference in price represents the "cost" that you paying for tough, enforced regulations and for higher ethical standards. Most American consumers do not want to pay this cost directly, so Walmart (a.k.a. the clearinghouse for Chinese products) prospers. Still, most Americans do pay this cost indirectly via, e.g., higher medical bills.

      • "The difference in price represents the "cost" that you paying for tough, enforced regulations and for higher ethical standards."

        Not quite. That difference is enlarged by many other factors such as unions, bribery, and unenforced monopoly laws.

    • I don't know how dangerous Apple's adapters are, but they sure put a rather nasty load on the two inverters I regularly use my PowerBook on.

      Both inverters will only start if only the Apple adapter is putting load on them. One of the inverters will crash and reboot if you put additional load on it together with the Apple adapter (1 kW inverter producing 220 volts from a 305 Ah battery.) I have never seen this behavior with any other load I have put on those inverters.

        This sort of behaviour is fairly common with small switchmode supplies - in fact, it's more likely if the power supply is well-designed and over-rated.

        It's to do with the current waveform. Any switchmode supply tends to have a very spiky current load, as it switches on an off to keep the output voltage stable. A cheap switcher, if it's lightly loaded, will draw huge spikes of current only in the early part of each half-cycle - so it's current load looks just like one or two noise spikes, which get absorbed by any output filtering &/or ignored the protection circuitry in the source UPS/inverter.

        A better switcher, on the other hand, will spread that current draw over the each half-cycle - so it's current load looks like a continuous noise hash to the supply. Enough hash to get back past any output filtering on the UPS / inverter and trigger the protection circuitry.

        Hence the reason any decent UPS or inverter has specific warnings and / or deratings when used with switchmode loads.

        (Yup, that's a simplified explanation - but it's also basically correct...)

        In your case, it would probably work better with a smaller inverter, or a cheaper & nastier one without such good protection circuitry ;-)

    I'm always curious to know exactly how many people are reporting issues when someone claims there's a major widespread problem. If a few dozen people complain of a problem it may sound like a lot. But if it's only a small percent of all customers it could be specific to only one lot of adapters or one specific subcontractor. He claims there's a design flaw but many thousands of people have been using these adapters for years with relatively few complaints.

    Dell and other PC notebooks suck and blow, but mostly Dell, cause that Dell guy said something bad about Apple, which makes them the worst. So we all know that Dells exploding and killing puppies and children is just another Tuesday.

    Of course Apple has always been perfect. Many people even actually sit around wondering just how it is they stay so perfect. I know because I'm in a club. That's why it just boggles they mind that somehow something isn't perfect with the power adapter. Probably because they got it from Dell. So just know it's less than absolutely perfect and keep an eye on it.

    Anyone that has owned powerbooks or ibooks knows about the crappy power adapters. I have personally lost three, of which only one was covered under warranty. The two biggest weak points:

    1. the connector that plugs into the laptop did not have enough ribbing material, so it frayed easily.
    2. the thin cable that runs from the laptop into the brick had zero ribbing, it just simply ran into a hole. Frayed easily, I even had one catch fire.

    After three Apple laptops I even started noticing how Apple tried to attack these problems. If you look at the last power supply shipped before the magnetic connectors came out, you will see that the "thin" cable is almost twice as thick as the one that shipped with iBook G3s and Titanium Powerbooks. You will also notice much thicker ribbing at both ends of that cable.

    The worst of this is that the apple branded adapters were $79 apiece, while a perfectly working replacement, with much sturdier cables, could be had for $35.
    • After 3 Apple laptops, I've had no problems, I've had a G3 iBook, a G4 Alubook and now I am on a G4 iBook.

        Maybe it's because we're from the camp who don't abuse their belongs though. If the cable is getting enough tension on it to cause tearing and fraying, you've been doing something wrong for a very long time. It doesn't take a genius to look at a power adapter with cabling and ribbing the size of a minijack headphone plug to realize, "maybe I should baby this a little."

      I have yet to see a single pack catch fire. And I've replaced quite a few of them. Damaged, yes. They definitely need to improve their strain reliefs, and magsafe is brilliant. But defective by design? Not from a safety perspective. They DO need to improve the strain reliefs though.

      If one tire in 20,000 started to bulge on the sidewall after 30,000 miles, and the owner didn't notice it until 2 months later the tire blew, you can't blame that entirely on Goodyear. All products break, and the consumer does have a reasonable responsibility to identify a product that has failed and may create a safety hazard.

      Now take the ibook g3 logic board recall. Now those I have seen maybe 4 dozen of. THOSE are defective. But THIS, this is just a blip.

    I don't think he's qualified to say that his adapter has zero short-circuit protection.

    Here's what he says: Meaning, I can short the adapter on the DC side, generate a spark, and repeat again and again without causing the adapter to power off or any circuit breaker/fuse/GFCI outlet to cut the power.

    He's expecting the wrong results. Sure, shorting any supply with output capacitors will generate a spark -- that's typical good design. The spark doesn't last long and it isn't indicative of the total energy released.

    Now, if his circuit breaker or fuse triggered, I'd be concerned. That means the adapter is shorting out the mains voltage -- very bad, very dangerous. But, it apparently is not. It's good that this doesn't happen, but the guy seems to think it should. And a GFCI wouldn't trigger due to a hot-neutral short [] -- he would have to throw the adapter in a bathtub to have a chance of it tripping.

    I'm not saying there are no problems with the adapter, but his assertion is unsupported by his evidence. I suspect that the adapter has an internal short-circuit protection that kicks in milliseconds after the spark is seen. He would need to use a current meter to detect if the circuit exists.

    (why, yes, I'm an electrical engineer)
    • The power supplies I've used (PC supplies) cut out immediately if shorted and need to be unplugged before they will provide any more current.

    Two years ago I was on vacation and staying with a friend when her pet rat decided to chew through my iBook G4/800's power cord. I wrapped a piece of duct tape around it and it seemed to be OK, but a few days later I plugged in the power cord and heard a clicking sound coming from the adapter brick. The inner insulation had been breached, and the two wires were touching.

    I cut and stripped the wire with a pair of fingernail clippers, twisted it back together, and wrapped it back up with the duct tape. Several months ago the duct tape came loose and the wire shorted again. I re-spliced it, and wrapped it with Scotch tape, which was all I had on hand at the time. About a month ago the Scotch tape started coming off (as I had known it would), so I retaped it with white electrical tape.

    I do freelance IT work, and haul my iBook everywhere. My power cord gets unplugged, wound up, stuffed into a backpack, unwound and plugged in somewhere else pretty frequently. Even when completely shorted out, all it did was make a clicking noise. The adapter brick can get pretty warm, especially when it's not well ventilated, but not uncomfortably so.

    I think companies, including Apple but especially Dell, have issues with squeezing their suppliers just a bit too hard. They negotiate one price for a given volume and simply short-change the supplier. Then the supplier has to decide between (a) taking legal action to recover their money and thus kill their relationship, or (b) eat the margin. That's how companies like Dell figure it.

    Unfortunately, there is an option (c) that basically says they will cut just a few too many corners so that they can only just meet the bare minimum requirements and stick it back to their abusive customer. This is, at least in part, what you're seeing today.

    • "taking legal action to recover their money"

      how is this an option? suppliers negotiate their contracts so if they lose money it's their fault.

      Dell is better at negotiating with suppliers than the competition. That's good business, not abuse. A vendor can choose to not do business with Dell and some do.

  • The adapter that came with my PowerBook G4 one day sparked and burned some of its own insulation. The reason being, is I had put too much stress on that area of the cable (next to the plug that goes into the computer) over a year and it had become frayed. It was out of warranty so I bought an adapter off eBay and now I make sure to put no stress on the cable if I can avoid it.

    I'd say that this could happen to any electrical device.

    This article makes some sense. But when he tries to explain that it should trigger an GFCI (or even AFCI), he gets way off track.

    It would never trigger an AFCI, because there's too much smoothing circuitry between the output and the wall plug. No matter, as an AFCI is designed to protect against arcs in the walls and frayed AC power cords. So the AFCI comment didn't make sense.

    Also, the GFCI comment doesn't make sense either. A GFCI is supposed to notice power being drawn and not returned on the neutral. The Apple power supplies are designed to be 2-prong devices, so they could never dump significant power on the ground pin and trigger a GFCI. The only way it could trigger a GFCI is if you shorted the live end of the cable to a separate return, like earth ground or a hot tub or whatever. Then the power would not come back on the neutral and would trigger the GFCI.

    Anyway, a GFCI is supposed to prevent against things like dropping a live appliance into a puddle of water or whatever, not shorts internal to low voltage cables.

    His spark test maybe means something, I see what he is talking about there. But I'm not sure about his testing methodology. Maybe he's testing a case expecting it to shut down and instead Apple just current limits, which is an acceptable alternative. I just can't tell with only the data on that page.

    The article summary is definitely full of unwarranted hyperbole. The article isn't even close to triggering a level of "source of some serious safety concerns".

    We've had two of these go.

    I have a photo on our blog too: 274/index.html []

    About 4 headlines in.

    You'll notice from the blog I'm pretty much an Apple Fan Boi (tm) but even I in my Appleuphoria can see that this is a problem.

    My wife's iBook power adapter malfunctioned a couple of months ago, it started to crackle and even let out a few sparks! The replacement runs for about US$80.00, a ridiculous amount for a product that is raising a stink in forums all over the web because of its' horrible quality.

    However, I decided to inspect the adapter, detached the A/C plug, which snaps on and off the corner of the adapter, and was horrified to notice it was thoroughly charred on the inside. Then, I vaguely recalled that a power cord came with the iBook, in the box. This is what I'm talking about: []
    To my great relief, the new power cord snapped neatly into the corner slot of the adapter, and ran smoothly. It was the detachable A/C plug that was defective, not the adapter itself. Now, not only could we throw the defective plug where it belongs (in the trash), we also had made our device safe, as well as doubled the length of the cord, and saved ourselves $80.00 to boot! My wife and I were happy campers that day.

    So, if you have an Apple laptop, check this out for yourselves and I'm sure it will allow you to solve/avoid this exact problem, and even if it's not malfunctioning yet, do it now, no use putting your expensive computer at risk. Also, even if you've misplaced the box and/or cannot find the power cord, buy that instead, as it's price starts at around $10.00, saving you quite a bit of cash in the process.
