Vention HDMI to VGA Converter with Female Micro USB and Audio Port (ACHBB) is an adapter that converts a digital HDMI signal to an analog VGA video signal, with the addition of a 3.5mm audio output and a Micro USB port for supplemental power. It is a one-way converter, meaning it only works from an HDMI source to a VGA display. 

Connectivity: HDMI male input to VGA female output.
Audio: Includes a 3.5mm audio port to carry the sound signal separately, as VGA does not transmit audio.
Power: Features a female Micro USB port for additional power when connecting to devices that don't provide sufficient power through the HDMI port.
Resolution: Supports high-definition resolutions up to 1080p (1920x1080) at 60Hz.
Material and length: A 0.15m (15cm) black cable with gold-plated connectors for stable transmission. 

Connect modern devices to older displays: Allows you to connect a modern device with an HDMI output (such as a laptop, PC, PS4, or TV box) to an older display with a VGA input (such as a monitor or projector).
Plug and play: It is generally plug-and-play, with no additional drivers required.
Audio and video support: Unlike some simple VGA adapters, this model carries both video and audio signals, providing a more complete solution.
Stable signal: The Micro USB power port helps ensure a stable signal, particularly for high-power devices or those with lower-power HDMI ports
