Chargers are quite blind(or immune) to this spec. They have internal regulators for their MCUs.

I just scored a universal dc power supply for lap tops from my local pc shop for £2.

15 - 24 v output

what do the micro controllers do that negates the pressance of ripple current from less soficated power supplies?

Are you sure a £2 PSU will do the job? What is the max current or power rating of that thing?
