ZIP™ CHARGING
Zip™ is a high speed charging system for Vapor Shark devices. We’ve
integrated proprietary charging technology that works to charge your
device up to 2.3 times faster than previous models.
Our long awaited DNA 200 is everything you've been looking for in a mod.
Sleek, pocket friendly, powerful and completely customizable. Unlike the
DNA and rDNA, the DNA 200 is made out of 6031 aluminum, making it
lighter than it's predecessors. The finish starts with a black anodization
process, followed by black paint and then a light rubberized coating
completes the process. Truly our most durable finish to date.
Zip Charging is on board to make sure charging is done in a flash when
plugged in to a 2A power source. No one likes waiting for their batteries to
charge. The DNA 200 is powered by a 3 cell 10 Watt hour lipo pack. One
of the best features of the DNA 200 is Escribe."
