and this thing is cool. I got a black 650 passthrough one. I thought this thing would just be too big, but I kinda like the way it feels, kinda like a cigar. I also like that the usb plugs right into it so i don't need a separate charger and since there are USB ports darn near everywhere I'm at, this thing should never run dry. I'm not sure why this is not a standard option, it just seems soooo much more convenient. PCC and little batts, you have served me well, but it is time to pay you forward. Now for some 2 ohm cartomizers.
