- 【Capture While Charging Your Tablet or Pad】 Designed for tablet, pad, and compatible USB-C host capture setups, this capture card supports PD 3.0 100W USB-C charging passthrough to help keep the device running the capture software powered during live broadcasts or long recording sessions. Please note: the charging function only supports the USB-C host device on the capture/software side, not the HDMI source device or display device. Note: A 100W charger is required to achieve the same fast charging speed; The capture card may heat up slightly during charging, but it's normal

- 【Note】This capture card supports one-way transmission (HDMI to USB-C). Video input via USB-C to HDMI conversion may cause signal loss due to cable protocol differences. If the PS5 shows a black screen, please disable HDCP. Use a USB 3.0 port whenever possible to ensure bandwidth and resolution. The capture card works through video decoding, which introduces millisecond-level latency, and different video formats (MJPEG, YUY2) support different resolutions. Signal loss may occur if the device disconnects; reconnect or restore default settings. To check if the capture card is functioning properly, connect the USB port to a computer or tablet and open your capture software to confirm detection
