Cheap & Good PS2 slim external PSU option : USB-C PD

If you own a 70000-79000 PS2 slim, and you need an external power supply, you can easily power your PS2 slim over USBC PD with a couple of adapters for cheap !
This is also useful if you wish to power your PS2 on a portable battery station (or a car) without having to use a transformer, which has its own downsides (including the bulk, efficiency etc...).
