Compact for travel, yes. There are no bulky stones here. I use it for my Surface Go. Loads pretty fast. However, I have learned to deal with it. Because during the charging process, after about 10 minutes of connection, my touchscreen starts to glitter. I tap the screen to select something and it looks like I tapped multiple times to open some other apps! I can easily use my keyboard and touchpad while charging. But I can't use the touchscreen because sometimes it gets spasmodic. My MS power supply for Surface does not have these problems. I got this for travel and charged up while walking. You just have to know how to use it. YMMV.
