I've actually just had different plugs for the lights and the charger, just plugged the charger to the hub when I wanted to use it. Which has not been that often, as I have Etrex using AAA batteries. And then the charger is separate from everything else, in case it fails. And it doesn't add any resistance when it's not plugged in.
