- USB 1.0: Capable of data transfer speeds of up to 12 Mb/sec. This is not fast enough to use as a video cable connection. USB 1.0 carries an electrical current of 5 volts (V), 0.5 amps (A), and a max power of 2.5 watts (W), which is not enough power to support fast charging.
- USB 2.0: Capable of data transfer speeds of up to 480 Mb/sec. USB 2.0 has the same power output as USB 1.0 and does not support fast charging.
- USB 3.2 Gen 1 “AKA - USB 3.0”: Capable of data transfer speeds of up to 5 Gb/sec which is fast enough to use as a video cable. Like USB 2.0, they deliver a power output of 5V, but unlike USB 2.0, they can deliver nearly double the watts (4.5W) and amps (0.9A) of a normal USB 2.0 cable. This means the cable can charge a little faster than a USB 2.0 cable but is still not considered a fast-charging cable.
- USB 3.2 Gen 2: Capable of data transfer speeds of up to 10 Gb/sec and are capable of video transfer. USB 3.1 Gen 2 has a power output of between 5V to 48V, between 0.5A to 0.9A, and up to 240W. These cables are generally considered fast charging cables.
- USB 3.2 Gen 2x2: Capable of data transfer speeds of up to 20 Gb/sec. This is fast enough to use as a video cable connection. They have the same power output as a USB 3.1 Gen 2 cable and are generally considered fast charging cables.
- USB 4.0: Capable of data transfer speeds of up to 40 Gb/sec. This is more than enough speed to use as a video cable connection. They have the same power output as a USB 3.1 Gen 2 and USB 3.2, and are generally considered fast charging cables.
