The Voopoo Drag X2 is a refillable pod kit for people who want some control over how their vape runs. It works off a single 18650 battery, sold separately, so you can swap in a charged cell rather than waiting on a recharge. Power ranges from 5 to 80 watts, enough to cover a tight mouth-to-lung draw right up to a looser, airier direct-to-lung pull. There are three modes to switch between. Smart mode reads the coil you've fitted and sets a sensible wattage on its own, which is the easy option. Eco stretches the battery further between charges. RBA mode hands you manual control if you want to dial the power in yourself. Switching between them takes a couple of clicks. It suits someone stepping up from a simple pod who wants room to adjust without jumping to a full box mod.
