Perhaps the biggest annoyance to those who enjoy their portable vaporizer on the go is that the coil heating system wears out too quickly. Evoke has set out to make a vape system that caters to enthusiasts in more ways than one. The dual-sided gadget has a rounded side that fits easily into the palm of the hand, or flat side for sitting securely on the table. It also uses induction heating rather than the coil heating method, so it lasts longer, heats faster, and is able to control the temperature instantly while still remaining cool on the outside. Early bird backers can get theirs for $79.
