This mini USB monitor runs purely off of USB port, it does not need any batteries or power cords and it’s got built-in video card. All these also save you the hassle of having to bring power cords and batteries that may add some little burden.
This mini USB monitor provides decent brightness and contrast and can be used in either vertical or horizontal orientation. It weighs less 1 kg (1.3 pounds about 590g), which should be light enough for any kind of user to carry it around. The price tag of $130 sounds little steep.
