The Mega Volt by Council of Vapor.
This device packs a massive punch for its size, with a whopping 80W running a built in 1750mAh battery. It also includes a full 510 connection for those who need some real power on-the-go. Fitting in the palm of your hand, its lightweight, yet sturdy design allows for it to be pocketed without weighing your pockets down. The Micro USB port in the bottom charges the entire battery within a Half Hour! On top of all that, it has temperature control features for Ni, SS, and Ti making this tiny device capable of more than many others in a similar size.
