Good battery life (about 2 days) for this little box coupled with a AeroTank V2. Fast charging (about 2:30 on sector). Ability to pass a variable voltage or variable power (3 consecutive presses of the power button) or 0.1W 0.1V increments. Note that it is possible to vaper while being supported. The screen is visible. It lets you view the battery charging status, voltage, power and resistance value. In short, my Spinner V2 replaces bored ... Fast delivery and careful.
