Just opened my mail from a couple of days ago and found I had received a passthrough I ordered just a few days before. It screws right onto my 510 Evod tanks and has a USB connection - no battery needed. Only warning is to not plug into a computer. Plugged it into my power bar beside my comfy chair, which conveniently has a couple of USB ports, and sorted out the only control. It has 4 voltage settings, from 3 to 4.8, so I set it to 3.6 as the closest to my Evod battery (3.7) and I'm vaping away, happy as a clam. Now I won't be running back and forth, charging batteries when I'm into a good book or a movie marathon! I think it might be really nice on a road trip, too, plugged into a cigarette lighter USB charger. Anybody else find one of these? Haven't found anything about them on this forum.
