I bought this charger for my phone back in February, after my bags had been lost on a flight through Paris.
For a while, I thought it was a bit of a waste to have an LED light up whenever the charger is plugged in. LED’s don’t consume a significant amount of power, but over time, electronics left on standby or mobile phone chargers left plugged in to the wall drain up to 10% of a households total energy. This little red LED was yet another tip of the energy iceberg in my apartment. After some time however, that turned out to be a good thing. The red light serves as a reminder that the charger is still drawing power and, if I’m not currently charging my phone, I should pull it out. The LED’s consumption turned out to be a tiny price for a much greater savings.
