Is There Phantom Power Usage In Your Home?

The takeaway for me from all of this is that modern computers and computer-like devices, as long as they are not desktop computers, use almost no electricity. He plugged in 11 devices, almost all of which can act as computers of a sort, and they maxed out at 195 watts total. That’s less than 20 watts per device, less than the power it takes for a 100-watt-equivalent CFL bulb. And when they were charged, they drew less than one watt each. That’s not a phantom load. That’s a rounding error. The lesson: don’t give a second thought to laptops, cell phones, and other handheld devices when it comes to their power usage. Focus on the important stuff, like heating and cooling, lighting, larger electronics (I would love to see his measurements for his set-top boxes, wi-fi router, and cable modem) and large appliances.
