Could a USB port be used to power an external device?
I got a digital photo frame for christmas and was wondering if I could power it off of the USB ports on my computer. The rating on the plug says output 5V at 1A, if I remember correctly the USB power output is 5V at 500mAh. So If I connect two USB ports in parallel I should get an output of 5V and 1000mAh does that sound right or an I over looking something which may cause me problems?
Sorry to the others above me, but not really. 2 in parallel would indeed in theory, but is that shared between your ports ?
If you are clever enough to wire in parallel, may i suggest you pop into your pc and connect the red + and black – of a 4 pin molex (HDD and DVD) OR floppy drive connector for a lot more current. The Yellow and Black on the same cable will produce 12VDC. (Just incase you want to power your Nintendo DS from a car charger adapter withoug a car or mains like i did)
1 amp is a lot to ask for a USB port unless its designed for it, or get an ipod mains charger !!
Hope this helps !!
