Hi,

We bought a Creative ZEN V mp3 player. It comes with a USB-cable to
charge the li-ion battery through a pc. I want to charge this player
with a power supply (220V in). I think the ZEN needs 5 V at 2.4A (max)
it says at the internet.

That would be the MP3 player's maximum charging/operating current when
connected to an AC adapter.

I do have already a power supply witch says:
input 100-240V-50/60Hz 120mA, output 5V === 400mA. Is this save to
use??? Will it work?

Thanks for helping

Marcel

A USB port can only supply a maximum of 500mA. That would be the MP3
player's maximum charging current when connected to a PC.

Creative's web site claims that the adapter can "charge your ZEN in
less than half the time of USB charging". This begs the question, does
the MP3 player need to detect when it is connected to a USB host in
order to limit its current demand? Would this mean that a dumb 500mA
adapter would be overloaded?
