FØ uses alternating current (AC) to produce a waveform that runs continuously while you vape. This is possible by sending an electrical output in a much more precise and efficient way through the coil.

You can adjust the hertz output to match your coil and e-liquid. When properly matched to your atomizer, FØ will extend coil life, provide smoother heat transfer, and even enhance specific flavors in e-liquid. AC will heat your e-liquid at a gradual rate, ensuring that it does not burn and produce a bad taste, so many of us have experienced.

We recommend using FØ whenever possible, to take full advantage of AC technology.
