I'm building a RetroPi Box from an old Playstation 2, and I'd love to recycle as much of the PS2 components as possible.
My PS2 (first generation model) has a power switch for its 250V built-in power supply. Since hooking this up to the Pi would fry it, I thought I'd simply plug a stripped USB charger in between the two.
My train of thought was that since European sockets also supply around 220-240V, the usb charger parts would take care of the Volt conversion for me.
Is that right? If not, do I require similar components as this answer suggests?
The raspberry pi requires around 4-5V to run properly with USB devices attached.
