The DNA system lets anyone build Evolv’s revolutionary power regulated technology into their own products. The DNA 20D is a power regulated digital switch-mode DC-DC converter for personal vaporisers. It features controlled power from 7 to 20 watts, runs from a single lithium cell and includes protective features such as overcurrent, over and undervoltage protection and a thermal shutdown. It features a small OLED display, analog or digital user controls, onboard buttons and synchronous rectification for maximum battery life and minimal heat generation.
•Variable voltage: Adjust the voltage output from 3.0 to 6.0 volts in 0.1 volt increments.
•Variable wattage: Set the preferred wattage (from 3 to 15 watts) and the VAMO V2 will adjust the voltage automatically no matter what atomizer you use.
•RMS Out: RMS provides a more accurate voltage output.
•510 Threaded: Compatible with 510 atomizers, cartomizers, Vision Ego Clearomizer 2.0, eGo CE4 PLUS V2, Vision Vivi Nova Tanks, Smoktech DCTank and Kanger Clearomizer
•Can be used with single 18650, single 18350 or two 18350 (flat top)
