I'm new here but after banging my head around last night I tried to figure out how to plug my accessories in to charge without draining the battery on my JKU 2013. The center counsel 12 volt power adaptor is always hot even with ignition off. Final simple solution: 1 dual USB 12 volt adaptor (without a light) (I used Verizon Model BULLETYPC - DC201210, 1 USB IPHONE CABLE, 1 micro USB for blue tooth charging. Assuming you take your IPOD, IPHONE, blue tooth headset out to use when you aren't driving your JEEP and you leave the cables in, this works very well! Hope this helps!
