I'm assuming it means it's the same as the Chromecast, i.e. it isn't powered from the HDMI port.

Chromecast is typically powered by the USB port on the TV, not the wall. I'm not going to buy this if I need to plug it into the wall.

Chromecast is powered by USB, whether that comes from the TV or the wall depends on whether the TV has a free USB port (which requires having a USB port to start with.) I suspect lots of Chromecasts are used with older, pre-USB TVs (the popularity of TV USB ports largely coincides with Smart TVs, and Chromecast adds more to a TV that isn't already a Smart TV.)
