The Freemax Twister combines the capability of a vape pen with the versatility of variable wattage. Driven by an interior 2300mAh electric battery, you can fire at up to 80 watts by simply rotating the bottom of the battery. It still has the usual solo button design you’d expect in a pen vape, with LED indicators behind it to show you remaining battery existence. Perfect for Sub Ohm vaping on the run or for those just engaging in variable wattage.
