how sensitive is a portable cd player in regards to voltage?
I have a portable cd player that runs off of 2 AA batteries outputting 1.2v at 2000ma each wired in series,.I also have a car adapter that can output 1.5v, 3v, 4.5v and it has a USB setting. The adapter is rated at 1000ma. My question is if I wired that adapter directly into the cd player would I be able to run it?
the two batteries add up to 2.4 volts. I'd use the 3 volt setting, since many AA batteries are 1.5 volts each, and the player should run on any type of AA battery without damage.
I doubt the CD player actually draws 2000 mA or 2 amps from the batteries as they would last only minutes at that drain. So the 1 amp capacity would be more than enough.
