The Smok GX 2/4 is a transformer of sorts; able to switch from two batteries to four batteries by swapping an included battery door and adding in the extra batteries.
The Smok GX 2/4 APV (advanced personal vaporizer) box mod seems to be the spiritual successor to the Alien 220W. It is stylish, well designed, and powerful.
It has one of the smallest and slimmest profiles of any two battery mod in the industry. This is the perfect size for almost any hand from small lady hands, all the way to large meaty man hands.
When the Alien was first released it was received extremely well. It was the everyday workhorse mod for a large number of vapers including myself. This mod has become started to take over that spot.
It has the ability to fire up to 350W when using four batteries and 220W in two battery mode. The mod features a slim profile squeeze or front firing bar that is natural feeling to depress.
Smok bills the GX2/4 as the smallest two battery mods on the market and when in 4 battery mode it isn't much bigger than some three battery mods.
If you are looking for a powerful mod that is also easy to use and also looks attractive, this may be the mod for you.
This mod is also featured as part of the Smok GX 2/4 Big Baby Beast vape starter kit.
