Can a voltage booster be used with a VaporWorx controller?

In most cases, yes.

If your controller was purchased prior to June 2015 then the input voltage should be limited to 17.5v. Later versions are rated to 22v. The voltage booster should be used to feed the VaporWorx controller.

Note that many boosters lack sufficient power to drive high-power modules. The JMS FuelMax is the best unit we have used.
