Specifications for the M4U eX / M8U eX power supply
Even though M4U eX and M8U eX get powered via USB from the computer, for standalone operation and when using the integrated USB 3.0 hub, a power supply is required. This power supply is included by default, yet can be replaced with a standard power supply (which is not recommended by us).
