Hi,
I want to buy a portable MP3 player (not IPod), but it requires a
"high power" USB port on a computer to charge it. The alternative is to spend
around $30.00 for a "wall wart" type of charger.
I am a service technician, and I thought about using one of my regulated
power supplies. You can set voltage and current. Also I have the USB
connector (same type computer has), but I don't know what current
I should set to charge the MP3 player. I realize that may depend on the MP3
player, but I am looking for a nominal value as a reference.
Do you have information on the typical charging current?
Thank You in Advance, John
