Question about Macbook Air M2 ports

I just had the opportunity to look at the new Amazon Kindle PaperWhite model. It appears this unit has a USB C connector on it. So to charge it, you should only need the USB C cable that came with the Kindle. This cable should be able to plug directly into your MacBook Air.

Just checked online, and it appears the standard Kindle also now uses a USB C cable. The easiest way to check would be to see if both ends of the Kindle cable are the same...and then check to see if it plugs into your Mac.

If your Kindle had a USB C connector, you could plug it in to your MacBook Air directly. But I'm pretty sure your Kindle has a mini USB connector on it, and probably came with a cable with the mini USB plug on one end and a "standard" USB A connector on the other end.

Your MacBook Air doesn't have any USB A connectors. Both on this Mac are USB C connectors.

So to plug the Kindle into your Mac, you'd use the Kindle's cable to plug one end into the Kindle, and the other end of the Kindle cable into the USB A - USB C adaptor. Then the other end of that adaptor plugs into your MacBook Air.

The adaptors are usually stocked at the Apple Stores. Here's the one I'm referring to: Apple USB A to USB C Adaptor

You can also find them on Amazon, if that's more convenient for you.

You can get cables that go directly from USB-C to USB connectors other than USB-A. (As long as you can keep track of all of the mini and micro USB connectors around so you know which adapter cable to get!)

Apparently there is now a Kindle Paperwhite with a USB-C charging port.

Many previous ones have Micro USB (2.0?) charging ports.

You can charge other devices from a Mac using the Mac's Thunderbolt port provided you have the necessary adaptor. My Kindle, for example, has a mini USB charging port on it. If I wanted to charge it from my Mac, I'd use the Kindle's charging cable and plug that into a USB A <--> USB C adaptor then plug it into my Mac. To be sure I didn't drain my Mac's battery, I'd do this with the Mac plugged into power.
