Whilst the Drag S2 and Drag X2 both offer a generous battery life, variable power output and the same vaping modes: the Drag S2 features a built-in battery and the X2 a removable one. Which kit you should go for largely depends on your usage. If you’re after a simple recharge, go for the Drag S2. If you prefer not to wait, go for the X2 – you can swap your battery out whilst the other recharges!
