That "google" (actually TP-Link) router looks like a potential power hog: 3A@12V. Mind you, with a USB3 port not actually in-use, the baseline power consumption is more likely to be between 10W and 20W, but that's still not exactly eco-friendly.

TP-Link does have a smaller, cheaper ($12 vs $200) router that uses less than 2W power..
