I'm changed my mind

I have a kill-a-watt at home and decided to double check on my vampire phone charger. In 21 hours it used 0.01 kWh. Which seems like a very tiny amount. But, if you multiply that by 7 days per week that's 0.07 kWh, which is 70 Wh, which is like having a 70 watt lightbulb on for an hour. Which is actually significant. So, back to unplugging the darn vampires.
