I am new this is only my second post. Does anyone have info on the ego booster that you screw I to you're ego battery. It is supposed to turn the regular joyetech eGo battery into a variable voltage battery. Does anyone know if you use this device will it hurt the ego or void your warranty?
Here's a link to a detailed review of the Ego Booster. There's also a link to the vendor in the first post. They may be able to help with the warranty question.
