The Wismec Preva DNA pod e-cig is a high end pod kit, which can be used by a wide variety of vapers thanks to the different empty cartridges/pods available. With three power output settings as standard, they will change depending on the resistance of the coil in your atomizer head.
Vapers who want a more restricted draw and less vapour should use the 0.5ohm KTR cartridge, this will output 10W, 12W or 14W. Vapers who want more vapour and prefer to directly inhale should use the 0.25ohm cartridge, that will output 14W, 16W or 20W.
