Automatic
batteries?

Hmmm, haven't used those since the first week I began
vaping. Manual's are FAR better, but to each his own. Good luck in your search.
BTW, I've tried Smoktech and Boge, but by a wide margin Ikenvape cartos are the best. Better flavor and last longer. And good luck finding those in stock. (If interested, get on the 'notify me' email list)
