This cube can fit in your pocket very snug with your favourite 510 thread prefilled cartridge. With its new deluxe Camo, and Rainbow colour units, the Quatro is sure to steal the show. So we know it looks good but this baby also packs a punch and has the performance to back it up. It has 400mAh capacity meaning you can run this workhorse long and hard before needing a charger, it has 3 power settings maxing out at 4.2 Volts, and a useful preheat function. To make things simple it has a micro USB charging port on the foot of the battery and 15W of output performance.
