Charging
Some L2 charging stations are notorious for excessive parasitic draw. The stock 2013 EVSE uses a low quality transformer for internal power so it isn''t great, but it''s not bad. I doubt it would consume more than a few pennies worth of power per week, but unplugging it when not in use is not a bad thing.

The conservation of energy principle alone does not guarantee us that a charging device uses more energy while charging and less while not charging. A charging device could consume the same energy regardless of whether or not it is charging, by wasting power when it''s not charging.
Does Leaving A Charger Plugged In Use Electricity
Leaving it plugged into a laptop with a full battery will draw more power as it maintains the battery, so it''s best to unplug it from the laptop, if not the wall. It''s hard to say exactly how much power a laptop charger draws when plugged into a laptop that is switched off – it depends on how full the battery is, and how powerful the laptop is.
How Much Power an Inverter Draws with No Load
To find out how much power an inverter draws without any load, multiply the battery voltage by the inverter no load current draw. A 1000 watt 24V inverter with a 0.4 no load current has a power consumption of 9.6 watts. 24V x 0.4 = 9.6 watts. If you want to figure out the no load current in amps, divide the watts consumption by the battery voltage.
