Ubiquiti routers all use 8 watts (actually maybe only 6.5 watts for current gen gear). That comes to 5856 watt-hours per month. As of May 2013, the average price for electricity in the bay area was 22.8 cents per kilowatt-hours. $0.228 * 5.856 kilowatt-hours ~= $1.335. So less than $1.5 per month. | Ubiquiti routers all use 8 watts (actually maybe only 6.5 watts for current gen gear, and we should test that). That comes to 5856 watt-hours per month.

The Ubiquiti gear takes between 10.5 volts and 25 volts. I believe most of their official numbers state something like 12 to 24 volts, but one of their engineers posted a spreadsheet on their forum which listed the actual limits. | The Ubiquiti gear takes between 10.5 volts and 25 volts.
