No battery required; Just like riding a bike! Your hand is the battery of this device. The motion of your hand rotating the Spinner is similar to making ice cubes swirl inside a glass. The essence of operating the Spinner is not about how fast you rotate your wrist. It¡¯s about how to synchronize your wrist rotation to the momentum and timing the rhythm of the rotor¡¯s gyration. The faster the rotor spins, the easier it is to operate. Make sure you start the Spinner with sufficient speed.
