Notes
HDMI Type-A (Standard) to Molex 4-pin: HDMI and power connectors serve completely different purposes. HDMI cables carry limited power (55mA at 5V) for features like ARC/eARC, but cannot charge devices. The HDMI Type-A (Standard) (HDMI) and Molex 4-pin (Power) are from different connector families.
