-d6bvS8IX6Q 0:01–1:03 — Everyone has come across a USB (Universal Serial Bus) at some point, but this is just a general name for connecting different devices.
-d6bvS8IX6Q 1:07–2:09 — However, some of these devices now use the new USB-C port.
-d6bvS8IX6Q 2:16–3:21 — USB 3.0 was launched in 2008 and came with a major upgrade of transfer speeds of up to 5 Gbps.
-d6bvS8IX6Q 3:26–4:16 — USB4 offers power delivery of up to 100 watts because it uses the USB-C port.
jD54dscsefw 0:01–1:06 — So many devices come with only the charging cable and not the actual charger, plug/block itself, which has the label on it stating what voltage and amperage rating it has.
jD54dscsefw 1:09–2:09 — That's part of the definition of that particular version of the USB standard.
jD54dscsefw 3:21–4:30 — Now, if there's no conversation, then the default is, our old friend, 5 volts.
jD54dscsefw 4:33–5:36 — What that means ultimately is that the conversation I just mentioned between the power supply and the device now includes a third voice, the cable connecting the two.
jD54dscsefw 5:42–6:48 — This one, I think, came with my third or fourth phone ago, right? So this is probably a good 10 or 15 years old.
jD54dscsefw 6:53–6:56 — I'm Leo Notenboom, and this is askleo.com.

字幕可核对事实展开收起

字幕依据：Everyone has come across a USB (Universal Serial Bus) at some point, but this is just a general name for connecting different devices. So in today's clip you will find a complete guide to the types of USBs. USB-A is the most popular USB standard and is found at the end of almost every USB cable nowadays. -d6bvS8IX6Q@0:01
字幕依据：However, some of these devices now use the new USB-C port. USB-C can be used in conjunction with Thunderbolt 3 technology, which allows Thunderbolt and USB-C to combine for 40 Gbps bandwidth. In addition to the types of USB connectors we talked about, each USB cable and port has a speed standard. -d6bvS8IX6Q@1:07
字幕依据：USB 3.0 was launched in 2008 and came with a major upgrade of transfer speeds of up to 5 Gbps. USB 3.0 has become USB 3.1 Gen 1, and can be recognized by its blue color and is compatible with previous versions. USB 3.1 was launched in 2013, and the transfer speed can reach up to 10 Gbps and received the label USB 3.1 Gen 2 (Now USB 3.2 Gen2). -d6bvS8IX6Q@2:16
字幕依据：USB4 offers power delivery of up to 100 watts because it uses the USB-C port. It will also allow content display at 8K 60fps resolution with HDR and even at 16K 60fps. Thunderbolt 4 is the next communications standard. The new standard can send 4K video content on two monitors or 8K on one monitor. -d6bvS8IX6Q@3:26
字幕依据：So many devices come with only the charging cable and not the actual charger, plug/block itself, which has the label on it stating what voltage and amperage rating it has. I've yet to find charging cables that come with such a labeling on them. jD54dscsefw@0:01
字幕依据：That's part of the definition of that particular version of the USB standard. Now, originally, USB A ports were limited by that specification to providing only one-half of one amp of power, 0. 5 amps or 500 milliamps, though that's been increased in USB 3 to nearly twice that, 900 milli amps, and even 1. jD54dscsefw@1:09
字幕依据：Now, if there's no conversation, then the default is, our old friend, 5 volts. On the other hand, if the two can negotiate something better, then yeah, that's what they're going to use. If that happens, your device will charge faster. jD54dscsefw@3:21
字幕依据：What that means ultimately is that the conversation I just mentioned between the power supply and the device now includes a third voice, the cable connecting the two. The conversation amongst the three of them then covers what the power supply can supply, what the device can accept, and what the cable can handle. jD54dscsefw@4:33
