Power converter for PSP?
For reference, if you’re running anything only designed for US power in the UK, you *need* a step-down converter, like this one or the device will literally blow up. Stuff designed for 100v at 60hz won’t take 240v at 60hz without the sort of serious stepdown linked above, and certainly not with a travel adapter. As I said, this doesn’t apply to the PSP, since the charger supports both voltage standards, but most other devices (US and Japanese consoles, in my case) absolutely require a stepdown.
