No extension cord comes with new Mac.

Apple stopped including the extension cord a few years ago, but old ones do work with current adapters and Apple still sells the extension cord separately. Personally, I have around a dozen of the extension cords from prior Macs (even one from an old FireWire iPod), and I am using several of them with older MagSafe and current USB-C chargers.

If you have an old one that's not working, it may have been damaged.

Make an appointment at an Apple store. Take your device, charger, and all your cables with you.

I get No power from the APPLE USB-C cord whenever the block is plugged into ANY of FOUR extension cords. BUT, the USB-C Cord purchased at Walmart attached to the block works fine when the block is plugged into any of the 4 ext cords. Should I start over with a new topic? If so, what subject/title? Defective block or USB-C defective?

What happens when you use the APPLE USB-C cord with the power adapter plugged directly into the wall?

Use any extension cord.

What am I not understanding? There is no extension cord provided. Get an extension cord from any hardware, superstore, etc. and plug the power brick into it.

What is a C cord or a C cable please

Your story is too confusing. It appears you are calling something an extension cord that is not.

Let us know what happens.

If you mean the Apple Power Adapter Extension Cable, the 'duckhead' connector at the charger-side of that has not changed in ~2 decades.



My Touch Wheel iPod from 2002 came with one for it's included FireWire charger, and that power extension cord works perfectly with the 96 W charger for my 16" MacBook Pro.

As stated, if your old Power Adapter Extension Cable is not working with your current adapter, the cable is damaged or broken.

Here's a picture of the cable-organizing/concealing box sitting under my desk at home, in there are five Apple notebook chargers ranging from a 60 W MagSafe from a 2008 MacBook to a 96 W USB-C from my 2019 16" MBP.

Two of them are MagSafe, three are USB-C. All have the same type Power Adapter Extension Cable, and since I've never bought one separately, they all came with a Mac or iPod...meaning must all be older than 2015 when Apple stopped including them (in fact, the newest one of mine is from the 17" MacBook Pro that I bought in 2011, and some are much older than that as you can guess from the aged gray color of some of them).
