All this talk of regulated power supplies reminded me of this product which
takes a range of inputs via the barrel jack socket:
Meanwhile, the CI20 can be powered from a USB port and employs a barrel jack
socket to accept that power. According to the hardware reference it is
actually "a 5V 4mm (shield) x 1.7mm (pin) center positive connector ...
identical to that of the original Sony PSP":
I'm not sure if either of these things are relevant here, though.
