According to the blurb on the Velvet Cloud site for the eGo v6 I bought, "This mod has 3 Voltage Settings - 4V, 5V, 6V with an indication by color on an LED band under the main switch. Remember this is a High Voltage system, so you must use high resistance atomizers. Also please note this has a 510 connection."
So okay on the connection, but then I read a review for these cartos and I see this, which is esp. important to me b/c I prefer tobacco flavors so far: "Remember, standard for flavors, LR for tobacco!"
Oy! So many factors, I'm dying here!
If I understand what we're saying above, maybe I want to get LR cartos and not use the 5 or 6 volt modes...and if I did I would cook the carto, right, not my battery...or my funky self, I hope!
