Hello,
From what i know the USB 2.0 has current limit of 500mA and USB 3.0 has limit at 900mA
I want to power from USB a device that requires 1200mA of current. I want to use a USB cable that can be attached to 2x USB to get more current 2x 900mA > 1200mA but i have question.
What will happen when i plug my device that requires 1200mA into 2 USB ports (so the current provided by USBs will be enough) and then like by mistake remove one of the USB cables so ill end up with one USB that can provide 900mA and a device that requires 1200mA? Can it damage my USB port/laptop motherboard or it will just make my device not work since it requires 1200mA?
