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

That was it, indeed...thank you!

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.
