Green = QuickCharge - 5v * 3A = 15 Watts; 9v * 2A = 18 Watts; 12v * 1.5A = 18 Watts Black = Regular - 5v * 2.4A = 12 Watts You could use the Green USB-A to charge your iPhone (or Android device). You can use the other port to charge a portable speaker. Or if you are really adventurous, connect the 4-Port Insignia USB-A Hub and use it to power a USB Fan, USB Lights, etc.
Sorry, there was a problem. Please try again later.The Black USB port is regular 5V/2.4A and the Green USB port is Quick Charge 5V/3A, 9V/2A, 12V/1.5A. The Quick Charge function is available when you are only using the Green QC port.
