Few Questions for nano like player

Right finally got my new mp3/amv player through the post today,
Few questions if you wouldnt mind answering them.

Can i charge the mp3 player though the usb port? if yes does the compuer need to be running or just switced on at the plug?

Also how long does it take to fully charge the battery and then how long will it last?

Thanks for you help

try it.
if the player says loading while the pc is off,
it works.

as far as i know u should not load ur player longer than 3 hours.
it should last for like 4-6 hours then

My one looks like Ipod and it fully charges in 2hrs on USB.

PC needs to be turned on^^

Mine is about the same.
The computer needs to be on though to push the power from the wall outlet into the player as a turned off computer generates outputs no power.
