Low Power Routers

Hi,
We operate quite a few solar sites and use RB493G as they are quite powerful and only use around 6w of power. What is the next generation of routers likely to be replacing these ? I notice a lot of the CCR say POE NO, or power consumption up to 60w, what is the actual DC power consumption of these if the power supply is removed ?

possible this one:
