I wish to connect a kanger evod clearomiser as directly as possible to a USB port - I have seen an option on a certain website I really liked, very compact, just a long cord leading to a short base with a button 510 threaded (don't remember if ego threaded or not)... but I don't remember which site it was or the name of the product. Although there are likely threads on here and other places on this subject I cannot for the life of me find them. I just want something bare bones and simple so I can connect it to a computer USB port or a car cig lighter -> USB adapter and vape with no battery. The majority of my vaping is near a computer or in my car so I could get one of these for the car, one for the computer then just use little 650mAh ego batteries for on the go. Product names or websites or links or anything really would be a great help. Thanks in advance.
