I don't think I've ever actually seen someone with a portable monitor... folks that have one, where are you taking it and how frequently?
I use mine for my PS4. Bring it with me when I go to a friend's house or vacation and I love it cause all it needs is just one USB port for power (which the PS4 has two ports) so just need one plug in outlet to use both the monitor and system. Only downside to the monitor that I use is that it doesnt have any built in speakers so I have to use an external speaker if I need the sound. I use mine probably once a month.
