Yes, very good. That is the charging cord for that particular device, many of thes types of "e-cigs" use USB chargers. That one is a Innokin VV Ver 3.0 which you can charge and vape at the same time sort of. Basically it will stop charging when I press the button, but will start up right again after. I can even charge in my car using the same mini USB as I use for my phone. It is good because the battery on that one is only 800mah, as opposed to the 1300mah device I can't plug in at vape at the same time. I prefer to call the Personal Vaporators. I hate the term e-cig. For me, that means those ciggarette lookalike things that don't work neary as well as a good PV and tank system.
