To charge a Mr Fog Max 1000, you actually don't need to—it's a disposable vape device that comes pre-charged and is designed for single use. Once the battery or e-liquid runs out, the device is meant to be disposed of and replaced with a new one. It does not have a charging port or rechargeable battery. If you're looking for a rechargeable option, you might want to consider other models in the Mr Fog lineup that are specifically designed with rechargeable features.
