I just ordered a usb to psp tip lead.
I thought it would be the most versatile and portable option because I could use it either to charge from a usb port on a computer or use one of the several usb mains adapters that I have acquired with other devices.

Unfortunately, I have discovered that all of my usb mains adapters are 400mA or less, but the Sony adapters for both the reader and the PSP are rated at 2A.

I know that usb current supply can vary, so if receiving power via the usb port my reader will be 'expecting' a wide range of currents, but if I'm charging it via the power socket, it will be 'expecting' 2A.

Can I cause any damage this way, if the reader tries to pull more than 400mA from a 400mA charger?
