I have a homemade passthrough that a buddy of mine fashioned for me, and I really don't want to place my computer's USB ports under so much stress. So, I was wondering where I might find a USB to A/C (wall outlet) adapter that'll run my PT. The ones I have right now don't work. I have the adapter to plug the charge chord in from an eGo charger (which delivers very little energy) and the USB to A/C adapter for my Kindle (which delivers zero energy [as far as I can determine from the atty not working at all]). I just need a single port adapter though. I've seen some on Amazon, but I don't know if they'd work or not, and I hate playing the "Let's see if that will work" game with Amazon.
