Repairing an Apple 45W Power Adapter M7332 (Yo-Yo charger)

Very interested to do this. Which wire did you use between the USBpower adapter and the Jack adapter?
I used a standard USB-C to USB-C cable, the same one I use to charge my Google Pixel phone.

But it doesn't look like that barrel plug has a USB port on its end.

I think I know which piece you are referring to now: https://www.amazon.com/USB-C-2-5mm-Emulator-Trigger-Laptop/dp/B07P81526M

My recent 1400cs acquisiton came with a yo-yo charger in somewhat poor condition. It has suffered from the cable being stressed too much at the base of the plug, a common fault with these, so it seems to provide power but only when the cable is pulled/wiggled a certain way.

Most posts online just suggest binning it and buying a new one, not so easy in 2023 and also not good for the environment... (I dread to think how many of these sit in landfill now)...

I already have a third party/new adapter to use with my 1400s and Pismos, but repairing this one would be interesting.

I read somewhere that they can be pried apart, but it sounds difficult. Ideally the whole cable would be replaced because this one has also yellowed badly.

Or, should I just attempt a repair on the barrel/end of the cable?

Any ideas? Has anyone attempted this before?

I have had the exact same problem with mine, and it can be easily fixed. Basically the two power terminals are connected with a little dab of solder, and over time of unplugging and plugging it in it disconnects from the PCB. I just had to resolder the two terminals and it was basically like new again.

I'm a bit late to the party on this, but it seems that the bix barrel plug adapter (http://www.bixnet.com/cntc11.html) is out of stock now
Does anyone know of a similiar one available anywhere?

Good thing I bout six a few months ago!

If we have a part number, perhaps Mouser has the same?

Deutschland?
https://www.amazon.de/-/en/PowerSmart-Power-Connector-Apple-Female/dp/B0CM8Z2BTH
It appears to be for a listing that only allows for shipping within Germany... couldn't even get a price.

...or Belgium?
https://www.amazon.com.be/-/en/PowerSmart-Connector-9x3-5mm-5-5x2-5mm-Female/dp/B0CM8Z2BTH
This one provides the price for me. €9.27.

I was able to order from Bix after following some links and ending up at a different Bix domain that had them in stock, and I have a tracking number now.

These were out of stock for a long time. I’d set up an email alert, and today I received good news. I immediately ordered 4.
