Notes
HDMI Type-D (Micro) to DC Barrel 5.5/2.1mm: 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-D (Micro) (HDMI) and DC Barrel 5.5/2.1mm (Power) are from different connector families.
