Are all USB ports the same?

New Specifications. There are now six USB specifications — USB 1.0, 2.0, 3.0, 3.1, 3.2, and USB4. USB 1.0 is old enough that you'll virtually never see it, so USB2-USB4 covers the spectrum for most people. Separately from that, there's USB-C, which is a physical connection standard that devices can use.

How do I know if my USB port is fast charging?

Check the Voltage and Current Output

If you see a cable that puts out power at 5V, 9V, 12V or even 2000mA, this is a sure sign that it's a fast charger. On the other hand, anything below 1000mAh is considered a slow charger. So look for 5V-2A or 5V-2000mA.

Do all USB ports provide power?

What is the power output from a computer USB port? Most computer USB ports supply 5V of electricity with a maximum current of 0.5A. This amount of current is standard across the majority of computers and means the overall power output will be 2.5 Watts at best. Later USB designs bring that current up to 0.9A.

What happens if you plug a USB into an outlet?

Absolutely nothing bad would happen if any standard USB device were plugged into a USB charger. At worst any "power" LEDs that light up when plugged into a computer would still light up, but nothing more. A USB charger puts out 5V unless the device negotiates a higher voltage.
