Wall Packs - there is nothing 'Universal' about it.

Would you believe the Wall Pack needed is not in the mix. How could this be possible?  How many variations are there anyway?



First, we have DC or AC packs with output voltages of 3, 5, 7, 9, 10, 12, or 15 volts. I actually found a 13.2VDC output. Why-the-hell would anyone design their circuit to run on a 13.2v Wall Pack?

And then we have center conductor positive or negative.  With that you could have over a hundred different types of connectors; Coaxial, Pin, Kycon, Molex, Empower, USB, etc.. And there are even different sizes of each connector.

Ajay Bhatt ran into this problem while at Intel.  Ajay is the guy who invented the Universal Serial Bus (USB) and connector.  What happened to his dream?  There is no 'universal' connector.  We now have USB; Type A (original), Type B (square), Mini-A, Mini-B, Micro-A, Micro-B, USB-3, USB-3 Mini, Type C and so on.

Let's face it, you'll never find the right wall pack so why even keep them. This is why they make wire cutters, black tape and benchtop power supplies. However, it does seem to be a bit extreme to power an Ipod.
