I don't know if there are better method, but I happen to have an
inexpensive external power meter, it looks like a plug with a small LCD
screen, capable of measure from few watt to 2000watt, display voltage,
power factor, and calculate overall power usage, so it is quite handy
for home use. It should be easy to find a good one in local shop or
online.
