PowerPoles are not meant to be used in "permanent" installations - they need to be "used" in order to maintain proper connectivity. PowerPoles , if left unconnected (or connected all the time) develop resistance in the two spring contact - enough to slow to a stop small 100 - 200 mW loads. Look at a cross-section of what little metal-to-metal contact is actually made. They work well when regularly plugged in and out - "self-cleaning." But if they are not engaged/disengaged often, the contacts deteriorate with corrosion, with resistance at small current levels .
