There is no ON/OFF button on the Julie Lindh Ageless Beauty Wands, and there is no light or indication that the wand is on, but if the solar panel on the handle is exposed to light, it will always be on. The wand is ready to use as soon as you take it out of the box and expose it to light.
The Julie Lindh Ageless Beauty Wands are solar-powered. The solar panel on the handle absorbs light and generates electricity. This panel acts as a built-in battery that gets recharged by either indoor OR outdoor light.
