    Is a USB C 'charging cable' different than any other USB C cable? Can I use a third party (sturdier) cable to charge my new MBP on order? I see the MBP charger accessory does NOT come with the cable.
    Again, needing to know more about cables than I ever needed (or wanted) to know before. It probably seems more complex than it really is.

    I am also curious. I am especially curious about wattage; nearly everyone seems to have decided that 60W is what USB-C does, so if you use a random cable with an 85W MBP charger, will it still work?

    I think it's risky, the MBP charging cable is beefy so unless you know the cable is rated for 85W it (the cable) could melt.

    • The USB-C specification is 100W; any compliant USB-C-to-USB-C cable will support up to 100W
    • The MacBook Pro comes with an Apple USB-C Charge Cable in the box, however if you buy another power brick separately it does not come with another cable
    • The Apple USB-C Charge Cable is called the charge cable because it isn't designed for data - it only supports up to USB 2 speeds. It does support 100W though as per the USB-C specification

    There are a lot of miscellaneous USB-C to USB-C cables on Amazon that are only rated for 12-15W, so I think one should still be careful.

    Definitely. Such cables are not compliant.

    The USB-C market seems to be a total mess. Even respected firms are putting out dangerous cables.

    So if it says supports 60w, move on? It seems most say that. Although even the Apple one says that on amazon. This is not easy.

    I'm not sure, and i've been using these for months and months. So complicated.

    What a mess. I hate wires to begins with, now this? :D

    I THINK there's power cables and (data/power cables?), that look exactly the same, of course, so you can't figure out which one is which. This is one of the benefits of the new system. :D

    So in effect, although it's simpler to have a single port, this is counterbalance by the plethora of cables and adapters that now adorn your desk

    If you are looking for a USB-C cable, I would advise the white Belkin one sold for £19.95 on Apple's website. That will definitely be compliant. Not cheap, but it saves getting something that will fry your laptop.

    it'll be interesting to see how many people start using cheap cables and it ends up stuffing their Macbook Pros.

    I tried to save myself money buying a new 85W magsafe charger on eBay and it turned out to be a fake, i got zapped a few times before i threw it away.

    Lucky it didn't fry my Macbook Pro.

    Since then, I'm prepared to pay a little more on the overpriced Apple cables in store.

    Wait a sec... the USB-C charger accessory you purchase from Apple doesn't come with a USB-C cable? WTF?

    This is correct.

    99% of the time I don't join the bandwagon that lambasts Apple all day, but £79 for a power adapter without a cable is just disgusting.

    It will drive people to buy fakes, unwittingly endangering themselves, their families, and their property, just so Apple can scrape a few more bucks.

    - It seems that one is for data rather than charging. It mentions 3A charging. I would think that means 15W (5V) rather than 100 W (which I believe is 20V 5A).

    This looks like the official charge cable. Says you can "pair" (is this wine?) with your charger.

    Apple recommends pairing MacBook with USB-C port with the 29W USB-C Power Adapter, 13-inch MacBook Pro with Thunderbolt 3 (USB-C) ports with the 61W USB-C Power Adapter, and 15-inch MacBook Pro with Thunderbolt 3 (USB-C) ports with the 87W USB-C Power Adapter.

    Hard to believe they do not throw one in the box. At least they seem to have them in all the Apple stores.

    Grr. The 13" MacBook Pro charges at 20.3V, 3A so it would be okay for that at least.

    It is certainly my understanding though that any USB-C compliant cable should support up to 100W. I'm sure that Belkin cable will.

    EDIT: The description on the Apple site recommends it for charging the new MacBook Pro. I'm sure they would've caveated it with 'except 15"' if it was truly limited to 3A. (The 15" charges at 20.2V, 4.3A).

    You're 100% correct but I believe OP was asking if they could use a different cable to this.

    - Yeah, I guess you're right. Odd that they're writing 3A, though.

    Isn't it the power cable to the charger not included with the new Macbook Pro.

    The USB C cable would be included, i thought it was just the "Country Specific" power socket cable that wasn't shipping.

    If you need to buy a replacement charger, why should you need to pay for another cable too? Chances are your original cable is still fine.

    That's correct. In the box is:
    • 2m USB-C Charge Cable
    • 61W (13") or 87W (15") power adapter
    • A region-specific "duckhead" (see image)

    What is not included, but normally is, is the duckhead extension cable:

    Well then they should make it $20 cheaper - right now they're priced the same as their MagSafe counterparts that include the (affixed) cable.

    I usually keep one charger where I normally use my mac. I keep another one in my bag for use away. So I'd want the full assembly.

    I think I have a couple of these to use with an early iPad but never bothered. Any reason they won't work with the 87w power adapter? The description says: "Use it with MagSafe and MagSafe 2 power adapters and 10W, 12W, and 29W USB power adapters." But it's just a power cable, so I it should work for all, right?

    Yep it will work with all of them, the site just hasn't been updated yet.

    Thanks.
    Now I'm curious about the size of the power adapter. If it's the size and weight of the Mag2, wouldn't it need lots of space in the outlet? Is it too heavy for a wall outlet?

    I'll buy the USB C 'power cable" from Apple since I don't want to be the one to fry a new Mac on an experiment.

    wall adapter for the 15" is the same size as the old 15" power adapter. Feels heavier, too. (I bought a few).
