Evolv DNA 200 

 

200 Watt Variable Power Module with Temperature Protection and USB 

Preliminary Datasheet 

The DNA 200 is a power regulated digital switch-mode DC-DC converter for personal vaporizers. 

It features Evolv’s patented Wattage Control, Temperature Protection, Preheat, Digital User Controls, 
OLED Screen, Onboard Buttons and Synchronous Rectification for maximum battery life and minimal 
heat generation. The DNA 200 runs from a 3 cell lithium polymer battery, and features cell-by-cell 
battery monitoring and integrated balance charger. The USB port and Evolv’s EScribe software can be 
used to customize or monitor the user experience. It is the most advanced personal vaporizer controller 
ever made.
