Raver2097 Posted April 20, 2006 Report Share Posted April 20, 2006 Hello JayKool_56,All I know about the USB ports of PCs is that they only deliver 5V :-[ that's not very high to make a PSU !And for the current, i don't know exactly but i think it might be 100mA.May this could help ...

SM2GXN Posted April 20, 2006 Report Share Posted April 20, 2006 Yes you are right, 5 volts is nominal, if more than 100mA is to be drawn from the USB the device should be powered from an auxilary supply but some USB,s will deliver up to 500mA. Don't know if the USB has any type of currrent limiter so one should be careful. Quote Link to comment Share on other sites More sharing options...
felto Posted April 20, 2006 Report Share Posted April 20, 2006 Go into your systems settings of your control panelthen click where it says usb ports and you will see thecurrent supplied for each. I thing it was between 450 and 500MA Quote Link to comment Share on other sites More sharing options...
Raver2097 Posted April 21, 2006 Report Share Posted April 21, 2006 Yes that's right ! I've just looked at my config and it says :"Maximum current available : 500mA"thanks for this cool tip ! Quote Link to comment Share on other sites More sharing options...
