what should be plugged into usb 2 vs usb 3

So one could say-like this web page does-that a USB 3.0 port has the potential to charge a device faster than a USB 2.0 port, but if the device itself is not designed to handle increased power output, it will just grab power at the rate it’s specifically designed for. So it’s completely dependent on the charging circuitry of the device itself.

It’s two way street in the world of charging: How much the power source is willing to give and how much the charging device is willing to take. I know USB 2.0 can provide 500mA and USB 3.0 up to 950mA, but is theĭevice able to draw the extra power the USB 3.0 port can provide andĬharge at 950mA, or will it draw up to 500mA and then not be able toĭraw any more? It takes two: The power source and the thing it powers. While you are asking this question as a general, non-device specific question, the reality is it’s completely device dependent nothing will take on more power than it’s designed to take and will limit it’s input to what it needs even if given more “juice.” More details below. I’m not askingĪbout a specific device I have, I just mean in general.

Plugged into a USB 3.0 port rather than a USB 2.0 one. Fairly simple question, do USB 2.0 devices charge quicker if they are
