John. a USB charger left unplugged will draw a max current of 1ma if your lucky and should be 0, now take a battery thats 11a. it takes 1000hrs (41days) to drain 1a at 1ma. guaranteed your cmos in the clocks will take more than that to keep your time accurate.
so unless the device thats plugged into the USB charger is constantly on and drawing 1-2a the charger is not going to drain a battery.
i have been using the older version of
THIS for about 4 years and its still going strong. mind you i do use one of my gizmo's for all my accessory's so i know its off when the ignition is.
