Does anyone know how long the iPad (3, new iPad) battery lasts with SkyDemon always on? Also, has anyone tryed the Cessna 152's cigarette lighter with iPad? I am not sure if the voltages are correct but I know that the SkyDemon Mobile MD comes with an aircraft power adapter (cigarette lighter) and I don't know if it works in the 152's lighter and the POH doesn't state anything about it, is this possible with the iPad?
