I just got an ego passthru and it works great. Has a long cord and I unplug it when it is charged and use it like a regular ego then. It is really handy because this is an area away from my normal vape area and other PV's. So I have a back up PV that is a passthru and can be used independently as well. Plus I don't have to drag my other PV's around to this area. Works great! bnrk
