Does the adapter support audio output through HDMI?
Yes, the HDMI port supports audio output along with video. Ensure your connected monitor or TV has speakers or audio output to take advantage of this feature.
Does the adapter require driver installation?
No, the USB-C On-the-Go Multiport Adapter is plug-and-play and does not require driver installation for most operating systems.
What is the USB port Specs?
We can confirm that the USB ports on the USB-C ON-THE-GO MULTIPORT ADAPTER support USB3.2 GEN1.
What is length of the two cables included?
The length are 4.5 inches for the hide-away flat cable and 32 inches for the long cable.
Can the adapter connect an iPhone 15 Pro Max to a TV/monitor without power, like Apple's USB-C HDMI adapter, or is power always needed?
Absolutely! The adapter works like a charm with or without power. However, for the best experience, we'd recommend keeping it plugged in.
On-The-Go Hub 4K 30Hz Video Output Issue- Firmware Update (Windows 10 device required)
Through customer feedback, we were able to identify that in some cases the On-The-Go Hub will only support 4K @ 30Hz with certain monitors. Although this is not a common issue, we have a firmware update available to resolve the 30Hz video output issue.
Please note: To complete the update you will need a Windows 10 device.
- Simply plug in your On-The-Go Hub to your Windows device, double-click the file (ST-UCMBAM Video Output Firmware Update.zip) to enter the unzipped folder.

- Then, open file ’00_Update_FW.bat', you will see a black command window and a progress bar pop up. When the progress bar reaches 100%, it will disappear which then means the firmware upgrade was successful.
If you do not have a Windows device on hand, please reach out to our support team by sending an email to support@satechi.com or by creating a ticket here --> https://support.satechi.com/hc/en-us/requests/new.
