Depends on the adapter Jwark sir. This thread explains each carto and says what it will or won't run on for the tank cartos-
Replacement cartos for tanks
As for the vv pt's, ego vv's, etc. something that needs to be touched up on, they all have an amp limit as well. Even with the best vv ego, a 1.5ohm dc carto will only run at 3.7-3.8v max. In other words not really a step up from the currebnt egos Vapor4Life sells with the 1.5ohm dc cartos. With the vv pt's, the only setting that will work with the 2.0-2.1a adapters is the 3.7v setting, and that's not a guarantee because even at 3.7v they need 2.46a of power.
