Review on Eviciv Portable Monitor: Touch Screen, Built-In Speakers, 7-Inch Display (1024X600), MDS-702 by Oscar Nemitz

I like it. I've been using this for the screen with a Raspberry Pi 4 for 2 1/2 years and it works really well. Being able to mount the Pi on the back of the display is handy to create a single wearable device. The display also comes with a good set of cables. Eviciv tech support was quick to respond to my question about the touch functionality issue - turns out I was just using the microUSB cable for power. They offered to send replacements. FYI, for mobile use: The display draws about 400mA at 3.3V or 1.3W. This equates to about 6W for the RPi 4.
