Rating 5v 100ma - Optical Mouse

The 100mA figure is also a strategic design choice regarding the USB standard. Under USB specifications, a device can draw up to 100mA before it must request permission from the host controller for more power (up to 500mA). By cabling the mouse’s maximum consumption at or below the 100mA threshold, engineers ensure that the device is a "low-power" USB unit. This allows the mouse to function on bus-powered hubs (hubs that draw power from the computer rather than a wall outlet) without the risk of triggering an over-current error or shutting down the port. It creates a seamless user experience where the device is guaranteed to work regardless of the specific USB port used.

But what does this current actually do ? In an optical mouse, the current powers three primary subsystems: optical mouse rating 5v 100ma

Mice with this specific 5V 100mA rating are versatile and found in several categories: The 100mA figure is also a strategic design
