    Universal Notebook Adaptor and "half-volt" rating

    I have a notebook computer requiring a 18.5V power supply. It works fine with a 19V power supply. Does that half-volt difference really matter?
    My first choice in quality Japanese electrolytics is Nippon Chemi-Con, which has been in business since 1931... the quality of electronics is dependent on the quality of the electrolytics.

    Nope
    As long as it has enough amps available you are fine.
    In reality that 18.5 v is 18.5v +/- (something) and it's probably like 10%.
