In an effort to minimize power consumption around the house to reduce greenhouse gas emissions, it’s important for us to know how much power each piece of hardware we have takes up. I’ve managed to get my hands on a P3 Kill-A-Watt and I’ve been using it wherever I can. With the SPF-85V, there is no power consumption with the unit off and fully charged, otherwise it draws 8W. With Wi-Fi enabled and storage devices plugged in, the SPF-85V required between 9 and 10W for operation, regardless of whether it was running through a slideshow or playing a movie. When charging the internal battery, it takes 12W.

When unplugged from the AC outlet and cycling through a slideshow, the battery lasts 42 minutes before warning you that the battery is dying. On the 43rd minute, the unit shut itself off.
