What is the USB output voltage on the computer?

The output voltage of the USB interface on the computer isDC 5V.

The standard voltage of the USB interface is 5V, and the industry-accepted tolerance is /-0.25V, so the normal situation is 4.75V-5.25V. However, in many cases devices can work normally if the voltage is lower than 4.75V, but it cannot be lower than 3.2V in any case.

USB devices mainly have the following advantages:

1. Can be hot-swapped. That is, when using an external device, the user does not need to turn off and on again, but can directly plug in the USB when the computer is working.

2. Easy to carry. Most USB devices are known for being "small, light and thin", which is very convenient for users to carry large amounts of data with them. Of course, USB hard drive is the first choice.

3. Unified standards. Common ones are hard drives with IDE interfaces, serial mouse and keyboards, and parallel port printers and scanners. But with USB, these application peripherals can all be connected to personal computers using the same standards. Then there are USB hard drives, USB Mouse, USB printer, etc.

4. Can connect multiple devices. USB often has multiple interfaces on personal computers and can connect several devices at the same time.
