Actually the product should be integrated, which might result in a lower value. I have a power meter, which does that. It gives me a power consumption of around 60 W with a "power factor" of around 0.55. So apparently the current is not in phase with the voltage. However most other power meters including most of those that calculate our power bills do not measure power, but current, so actually the phase shift or "power factor" does not count anyway. But if you use an electronic power meter if might measure the actual power consumption which is lower than what you pay for. So my MythTV box uses 60 W, but I pay for 110 W.
