Review on Portable Touchscreen UPERFECT Upgraded 1920X1080 15.6", 60Hz, Built-In Speakers, Flicker-Free, Ultrawide Screen, MDS-156G16, HD by Kenny Fusu

This monitor appealed to me because it offers a self contained battery and I like working from behind without having to power a second monitor. Battery life is pretty good when fully charged. I have failed several times for more than three hours without a full discharge. I'm pretty sure it will take four hours or more. The screen has a matte finish that helps reduce glare even when working outdoors. A few notes: 1. It charges via a Lightning USB-C connector. So don't make the mistake I made by plugging the charging cable into a different USB-C port that doesn't charge the device.2. If you use a USB-C cable from your computer's lighting port to the monitor's non-lighting port, you get a dual screen and the touchscreen works! If you're using an HDMI connection, you won't have a touch screen.3. It's really nice that they provide you with a wide range of cables in the box.4. The magnetic cover is also an added plus.5. The only downside (and since this is a monitor, that's not a huge minus) is that the sound quality and volume are rather weak when using the monitor. I just switch the audio output to my connected laptop and the sound is fine. The convenience of being able to slip this monitor into a case with a laptop and be able to work with two screens while working remotely is a huge PLUS for me, especially given the pretty decent battery life you get.
