What is the USB port power output?
I have a MacBook 2.26GHz Intel Core 2 Duo:(13-inch, Late 2009) – Model A1342 Polycarbonate Unibody ( MC207LL/A ) and I was wondering if anyone knows what the USB ports power output is ?
Exact voltage and current it can supply to an external device ?
or where I might find this information
Is this a good question?
