I somehow missed the ASUS MB168B+ USB 3.0 monitor. It is a 15.6-inch, 1080p, TN display that connects to the PC by a single USB 3.0 cord. This provides both power and video, so you can have multiple monitors on the go without struggling to find a wall outlet. At the very least, you can reduce it to just the one charging your laptop.
This was upgraded at CES to the MB169C+. It has a few differences. First, it uses an IPS display instead of the MB168B+'s TN panel. This should provide better color and viewing angles. It also switches from a USB 3.0 Type-A connector to a USB 3.0 Type-C one, which is starting to arrive in smaller laptops and tablets (which have to be running Windows for this device). The display is 8.5mm thick and weighs 1.76 lbs.
Pricing and availability vary by region.
