Wow, well I'm using a 510 now with a passthrough at my computer. I'm about to get an adapter to use it in my car as well. I've heard these things don't last long, but it's been working great for the past few days. I want something I can keep powered through a usb if possible, and lasts a long time away from it, and produces a great throat hit like my 510 does, although I have learned that not all 24mg nic juices are created equally, because some of my juices give a huge hit, and others not so much. So something that could really bring out the power in my vapes would be nice as well.
