Review on Thinlerain T-101-TOUCH Portable Touchscreen External with Built-In 🖥️ Speakers - 1920X1200 Resolution, 60Hz, Touchscreen, Wall Mountable, HD, HDMI by Som Holden

It's not in the product description. To use the touch screen, you need an external power supply in addition to USB. This is only documented in the instructions for use, not in the product description. If I had known that, I would not have bought this product. I need a portable flat panel display that requires as few connections as possible to my Lenovo Thinkpad X390 Yoga. It must be able to draw power and provide power, touch and video through the monitor's USB-C port and then daisy chain power to the laptop. I was willing to compromise with a smaller size to only get power and USB-C touch signal through the USB-C port and use the HDMI port for the video signal. When you need a portable monitor, you need as few ports as possible and no external power supply, connect the USB-C PD adapter to the monitor and your device. I want a portable monitor with the same functionality as the Lenovo Thinkvision M14t. This seller advertises it as such. I should be able to plug it into USB-C on my Thinkpad and only use the HDMI port for video. It is not so. Leaflet with instructions broke english speaking from chinese rubbish. Revain needs to add a field to item descriptions about where the item is made or make it an expandable listing condition. The only thing the Chinese did right was give us all the S-19s. I would also ask them to put their owner's manuals or brochures online so buyers can make an informed decision. Now I have to take care of the trouble of returning this garbage. A Tier 1 manufacturer like Lenovo performs a quality check on everything that is made overseas. There are no such manufacturers.
