How much mAh is the power supply from the USB interface of the general motherboard?
Generally, the power supply of the motherboard USB interface is 500mAh.
Because the USB interface power supply standard is USB2.0, the standard output current is 500mAh, which is also the maximum output current of the USB interface on most motherboards.
In addition, standards such as USB3.0 and USB-C also have their own output current standards, but their common application on motherboards is not as widespread as USB2.0.
Although the USB interface power supply standard on the motherboard is 500mAh, there are also some motherboards that can increase the current to 1A or more through different current adjustment technologies.
In addition, in order to ensure the stability and safety of the device's output, there are many USB interface-specific current extenders and power adapters on the market that can provide larger current output.
What is the maximum voltage of USB?
1. 5V
2. The USB (Universal Serial Bus) standard stipulates that the voltage of the USB interface is 5V. This is to ensure compatibility and stability between devices.
At the same time, USB also stipulates a maximum current of 500mA to ensure the safety and stability of the device.
3. The voltage and current standards of the USB interface are to ensure the compatibility and stability of the device, as well as to ensure the safety of the device.
When using USB devices, you need to pay attention to the power and current requirements of the device to avoid exceeding the maximum current and power limits of the USB interface, causing device damage or safety issues.
