Apple certainly did not invent folding pins…

…though I cannot relate to a British plug being a problem to carry around in a bag.
Interesting, thanks. Yeah seen those ones, hence wondering why we don't see more of them.

I notice they seem to all be made for "class II equipment - such as cell phone, tablet and build-in laptop chargers" which still require a dummy third "ISOD (Insulated Shutter Opening Device)" earth pin for power to start.

Perhaps this is why Apple only ever made ones for mobile devices (phones/pads), rather than ones for their larger laptops; due to certification not being possible on the larger ones?

Though perhaps the first "Slimplug" one could be adapted to force all three pins go up and down together, or something, to make it certifiable for use beyond lower-power devices? Who knows.

Certainly, it'd be good if Apple included that 18W folding-pin USB-C plug in the box with the next iPhone 11 (but given this is Apple we're talking about, they won't!):

...BTW, did you mean you can or cannot relate, in that sentence?
If you do mean you cannot relate, as to why they're annoying to carry in thin laptop bags and so on, or stamping your feet on them... then please elaborate.

Certification using a folding pin plug with a laptop should not be a problem. A better and simpler description of a Class II appliance is something that is double insulated, whilst anything that uses the earth lead for insulation is Class I. So all Apple portable devices are Class II.

Though as noted on that page with regard to the mu charger, because that Apple charger is a self-contained device without needing a lead it does not need to be certified. So maybe they are using a design that would not be approved for use with an adaptor or lead?

As for throwing plugs in a bag, I did mean "cannot."

Back in the olden days of plastic laptops with their dedicated bags I used to just wrap the power cable so it went between the pins so it would fit in the appropriate compartment without really adding any bulk.

Nowadays when I can just use a neoprene sleeve and put a MaBook in a regular bag, I instead use an old small carrier bag or similar and throw all my connectors, leads, and small accessories loosely into that. Until it falls apart I am currently using a fetching purple 10" square Superdrug one!

But even with a few plugs in there I have not even had any tearing of the cheap plastic bag by the pins. So I just cannot relate to carry them around being a problem.

Standing on them is annoying, though I would say there the failing there is not the pin design but in leaving plugs lying around on the floor!

I agree Apple would not do make the folding design standard when they can charge extra for it. But whilst I have no problem with the idea itself, the image on that Apple Store page makes it look twice as thick as a non-folding one, so it would be barely any less bulky to transport. If the problem is simply with the pins protruding then a cap for them to use when storing would surely be much simpler.
 
They stopped shipping these latest adapters nine years ago. I think their obligation to replace these for you gratis ended a while back. Did you expect these to last your entire lifetime? If you don't want to get the free new replacement, then don't. You don't "have to" go through this if you don't want.
Don't understand the "attitude" in the response. I happen to own one of the impacted adapters. I did not expect mine to last a lifetime, but they still function. These units are being voluntarily recalled by Apple and I have been contacted by them twice in the last few weeks, so they are reaching out to us. If they offer a program, it should be easy to replace them. Finding out it is not so easy sometimes (which I found out too) should be neutral subject one can post. Your mileage may when handling the recall. Recalls are normally gratis though, whether government compulsory or company voluntary. A recall is often far cheaper than a lawsuit with a significant damages / treble damages claim.

The chargers may be in use even if the original devices are not.

I'm typing this on my 2010 MacBook Pro 17 which is still functioning just fine. I got the power adapter kit to travel to the UK and Europe. Still functions many years later.
[doublepost=1557263989][/doublepost]I wanted to share my experience with recall since experiences can vary.

These power adapters are being voluntarily recalled by Apple, and I have been contacted by them twice in the last few weeks. First time I gave the Adapter Kit box and copy to the email to my brother who lives close to an Apple Store. I do not. The store would not replace it since the email was not to my brother, but he had the entire adapter kit with the recalled item and email with him. If safety is important, replace the impacted adapter rather than argue who is holding it in their hands and sending them away.

So later I get another email on the recall. Since plan a above did not work, I tried to setup a call. The website requires a serial number, and the World Adapter does not have serial number. I entered the serial number of my laptop, which is a 2010 17" Powerbook which still works fine. After getting a call back and going through 20 minutes of time, I was told that since my laptop is a "classic" model it is not supported by Apple so they cannot replace the recalled power adapter for me. An Apple Store might replace it they said (see above, but by my brother of course). I said the recall is for the World Travel Adapter Kit, which I bought, not the laptop. Try the store.....

Thinking the laptop I chose was the issue, I tried again later with my other laptop, a 2018 13" MacBook Pro w 4 USB C ports. So after 20 minutes or so I am told they cannot help me since the USB C powerbook was sold when the World Travel Power Adapter kit had already been updated and did not need a recall. Sigh.....

So when I get a chance I will try the store. I could just throw it out, but it still works fine with the power bricks, and if a safety issue then Apple likely wants to get them out of the hands of clients to avoid issues.

Maybe I had more troubles than others...not all customer service experiences turn out the way we expect, or would prefer, them to turn out.
